浅谈建筑环境与暖通空调能耗
浅谈建筑环境与暖通空调能耗暖通空调发展到今天,在满足人们众多功能要求的同时,不得不将考虑的范围扩展到建筑周围的生态环境。
能源的大量使用,对周围环境的无限破坏,这些都对人类发展产生了严重的影响。
如何建立一种生态的平衡,这需要我们暖通空调进行反思。
研究建筑环境,了解暖通空调负荷产生的原因及影响因素,可以更加合理地提出解决问题的方法。
1、建筑环境与暖通空调能耗概述(1)建筑与建筑生态环境之间的关系,本质应该是建筑去适应其生态环境,减少对环境的各种恶劣影响,而暖通空调系统此时便在建筑中发挥一种能动性的作用,利用各种方法创造良好的建筑生态环境,以此来协调建筑与环境之间的关系。
为了创造舒适的室内空调环境,必须消耗大量的能源。
暖通空调能耗是建筑能耗中的大户,由此可见建筑节能工作的重点应该是暖通空调的节能。
从暖通空调的能耗组成可以看出:暖通空调系统的能耗主要决定于空调冷、热负荷的确定和空调系统的合理配置,空调系统的布置和空调设备的选择是以空调负荷为依据的。
所以暖通空调节能的关键是空调外界负荷和内部负荷的确定,而暖通空调节能工作也应该从这个方面着手,合理布置建筑物的位置,正确选择外墙、门、窗、屋顶的形状及材料等,尽量减少空调负荷。
暖通空调的目标是为人们提供舒适的生活和生产室内热环境,在一般的舒适性空调中,以能够使人体保持平衡而满足人们的舒适感觉为目的;在恒温恒湿或有洁净要求的工艺性空调中,一切以满足生产工艺为目标。
而房屋的建筑热工设计是恰当地利用房屋维护结构的热导性,抵抗室外气候的变化,使房间内产生舒适的微气候。
(2)围护结构包括外围结构和内围护结构。
外围护结构主要包括屋面、外墙和窗户;内围护结构主要包括地面、顶棚、内隔墙等。
在采暖建筑中,围护结构的传热热损失占总的热损失的比例是较大的,在北京地区,通过围护结构的传热热损失约占全部热损失的77％;通过门窗缝隙的空气渗透热损失约占23％;在哈尔滨地区,通过围护结构的传热热损失约占全部热损失的71％;通过门窗缝隙的空气渗透热损失约占29％。

外文翻译ANALYSIS OF HVAC SYSTEM ENERGYCONSERVATIONIN BUILDINGSABSTRACTE conomic development and people's increasing demand for energy, but the nature of the energy is not inexhaustible. Environment and energy issues become increasingly acute, if no measures are taken, then the energy will limit the rapid economic development of the question.With the improvement of living standard, building energy consumption in the proportion of total energy consumption is increasing. In developed countries, building energy consumption accounts for 40% of total energy consumption of the community, while the country despite the low level of socio-economic development, but the building energy consumption has nearly 30% of total energy consumption, and still rising. Therefore, in western countries or in China, building energy consumption is affecting the socio-economic status of the overall development of the question. In building energy consumption, the energy consumption for HVAC systems has accounted for 30% of building energy consumption -50%, with the extensive application of HVAC, energy consumption for HVAC systems will further increase Great. HVAC systems are often coupled with high-quality electric energy, and our power and relatively tight in some areas, lack of energy supply and demand which is bound to lead to further intensification of contradictions. Therefore, energy-saving heating, higher professional requirements is inevitable across the board.KEYWORDS:energy-saving，HVAC1. Energy saving design measures should be takenRapid changes in science and technology today, area HVAC new technologies emerge, we can achieve a variety of ways of energy saving HVAC systems.1.1 Starting from the design, selecting, designing HVAC systems, so that the efficient state of the economy running.Design is a leading engineering, system design will directly affect its performance. The building load calculation is an important part of the design, a common problem is that the current design of short duration, many designers to save time, wrong use of the design manual for the design or preliminary design estimates of cold, heat load with the unit construction area of cold, heat load index, direct construction design stage as hot and cold load to determine the basis, often making the total load is too large, resulting in heating equipment, air conditioning is too large, higher initial investment, operating costs, increased energy consumption.1.2 using the new energy-saving air-conditioning and heating comfort and healthy mannerAffect human thermal comfort environment of many parameters, different environmental parameters can get the same effect of thermal comfort, but for different heat and moisture parameters of the environment of its energy consumption air conditioning system is not the same.1.3 Actual situation of a reasonable choice of cold and heat sources, seek to achieve diversification of cold and heat sourceWith the extensive application of HVAC systems on non-renewable energy consumption also rose sharply, while the broken part of the ecological environment are becoming increasingly intensified. How to choose a reasonable heating sources, has caused widespread concern of all parties.1.4 to enhance the use of hot and cold recycling of the work, to achieve maximum energyHVAC systems to improve energy efficiency is one of the ways to achieve energy-saving air-conditioning. Heat recovery system installed mainly through energy recovery, with the air from wind energy to deal with new, fresh air can reducethe energy required for processing, reducing the load, to save energy. In the choice of heat recovery, the should be integrated with the local climate Tiao Jian, Jing Ji situation, Gong Cheng actual situation of harmful exhaust gases of the situation in a variety of factors Deng integrated to determine the Xuanyong suitable heat recovery, so as to achieve Hua Jiao Shao's investment, recovery of more heat (cold) the amount of purpose.1.5 focus on development of renewable energy, and actively promoting new energyAs the air-conditioning systems used in high-grade, non-renewable energy resources and environmental problems caused by the increasingly prominent, have to develop some reasonable and effective renewable energy to ease the current tensions. To heat (cold) and solar and other renewable resources used in air conditioning and refrigeration, has certain advantages, but also clean and pollution-free. Ground Source Heat Pump is a use of shallow and deep earth energy, including soil, groundwater, surface water, seawater, sewage, etc. as a cold source in winter and summer heat is not only heating but also a new central air-conditioning system cooling.2. Saving design problemsAchieve energy-saving HVAC systems, now has a lot of mature conditions, but in practical applications there are some problems：2.1 The issue of public awareness of energy conservationThe past is not enough public understanding of energy, and on the air conditioning is also very one-sided view. For a comfort of air conditioning system or heating system, should the human body has a very good comfort. But the prevailing view now is: the colder the better air-conditioning, heating the more heat the better. This is obviously we seek the comfort of air conditioning is contrary to the view. In fact, this not only greatly increase the energy consumption of air conditioning heating, indoor and outdoor temperature and because of the increase, but also to the human body's adaptability to different environmental decline, lowering the body immunity. Therefore, we need to improve advocacy efforts to change public to the traditional understanding of air conditioning and heating, vigorous publicity andpromotion in accordance with building standards and the cold heat energy metering devices to collect tolls, raise public consciousness of energy.2.2 The design concept of the problemReasonable energy-saving design is a prerequisite. At present, some designers due to inadequate attention to design empirical value when applied blindly, resulting in the increase of the initial investment, energy consumption surprising, therefore recommended that the government functions and the energy-saving review body, to increase the monitoring of the HVAC air-conditioning energy saving efforts enhance staff awareness of energy conservation design, so that energy conservation is implemented.2.3 The promotion of new technologies issueNew technology in the HVAC system for energy conservation provides a new direction. Such as ground source heat pump systems, solar cooling and heating system, not only to achieve efficient use of renewable energy, and can bring significant economic benefits, is worth promoting. However, as with any new technology, these new technologies are often high in cost, and the geographical conditions of use have certain limitations, and technically there are still many areas for improvement to improve. Therefore, new energy-efficient technologies, we should be according to local conditions, sum up experience, and actively promote.3. ConclusionHVAC systems saving energy in the building occupies a very important position, should attract enough attention to the designer. Designers should be from a design point of view fully into account the high and strict compliance with energy standards energy saving ideas to run through all aspects of the construction sector. Energy-saving technologies and renewable energy recycling, the Government and other relevant departments should support and vigorously promoted. And the design, construction, supervision, quality supervision, municipal administration and other departments should cooperate closely and pay close attention to implementing a cold, heat metering devices to collect tolls, so people really get benefit from energy efficient building, energy-saving construction and non-heating energy efficientbuilding can not have the same charge standard. At the same time to raise public awareness of energy conservation, and vigorously promote the development of new energy-saving technologies to achieve sustainable development of society.References[1] "residential design standard" DBJ14-037-2006.[2] "Public Buildings Energy Efficiency Design Standards" DBJ14-036-2006.[3] "Technical Specification for radiant heating" JGJ142-2004.析暖通空调系统在建筑中的节能问题摘要经济的发展使人们对能源的需求不断增加,但是自然界的能源并不是取之不尽,用之不竭的。

空调节能技术中英文对照外文翻译文献(文档含英文原文和中文翻译)中英文对照资文翻译空调节能技术的研究1、引言节能可以说是楼宇自动控制系统的出发点和归宿。
众所周知，在智能建筑中HV AC (采暖、通风和空调)系统所耗费的能量要占到大楼消耗的总能量的极大部分比例，大致在50%~60%左右。
特别是冷冻机织、冷却塔、循环水泵和空调机组、新风机组，都是耗能大户。
所以实有必要发展一种有效的空调系统节能方法，尤其用是在改善现有大楼空调系统自动化上方面。
DDC(Dircctdigitalcontrol)直接数字化控制，是一项构造简单操作容易的控制设备，它可借由接口转接设各随负荷变化作系统控制，如空调冷水循环系统、空调箱变频自动风量调整及冷却水塔散热风扇的变频操控等，可以让空调系统更有效率的运转，这样不仅为物业管理带来很大的经济效益，而且还可使系统在较佳的工况下运行，从而延长设备的使用寿命以及达到提供舒适的空调环境和节能之目的。
一般大楼常用的空调系统有CA V、V A V、VWV等，各有不同操控方式，都可以用DDC控制。
（1）定风量系统(CA V)定风量系统(ConstantAirV olume，简称CA V)定风量系统为空调机吹出的风量一定，以提供空调区域所需要的冷(暖)气。
当空调区域负荷变动时，则以改变送风温度应付室内负荷，并达到维持室内温度度于舒适区的要求。
常用的中央空调系统为AHU(空调机)与冷水管系统(FCU系统)。
这两者一般均以定风量(CA V)来供应空调区，为了应付室内部分负荷的变动，在AHU定风量系统以空调机的变温送风来处理，在一般FCU系统则以冷水阀ON/OFF控制来调节送风温度。
（2）变风量系统(V A V)变风量系统(VarlableAirV olume，简称V A V)即是空调机(AHU或FCU)可以调变风量。
常用的中央空调系统为AHU(空调机)与冷水管系统FCL系统。
这两者一般均以定风量(CA V)来供应空调区，为了应付室内部分负荷的变动，在AHU定风量系统以空调机的变温送风来处理，在一般FCU系统则以冷水阀ON/OFF控制来调节送风温度。

将变频控制装置和光电感应装置安装在自动扶梯上，乘客进入扶梯时，扶梯以正常的速度运行，当扶梯内无乘客时将转为低速运行，其节能效果十分明显。
2.4强化管理环节特种设备安全节能运行关键因素在于人员素质及其管理制度的健全。
由于科学技术进步迅速，尽管特种设备操作人员和管理人员持证上岗，但是对先进工艺、技术以及设备的了解和掌握程度较低，使得节能所产生的效果并不显著。
因此必须对特种设备相关人员定期进行培训和考核，提高其特种设备专业技术水平和操作水平。
同时，相关部门应利用网络、电视、广播广泛宣传节能减排的重要性和紧迫性，提高全社会节能环保意识，在企业、机关、社区以及学校积极开展节能环保的科普宣传活动，促进特种设备节能、环保同步、健康发展。
3结束语作为高耗能、高污染的特种设备，其肩负的节能减排历史任务十分艰巨，其该空间节能减排的潜力较大。
因此企业、家庭以及个人应该提高对特种设备节能减排重要性的认识程度，在科学发展观的指导下，相关部门应积极采取有效措施，加强节能减排法制建设，建立节能减排工作相关激励政策，不断研发和推广新技术、新工艺以及新设备，强化特种设备相关人员的培训力度，加大特种设备节能环保的宣传力度，从而最大程度降低特种设备能源消耗，保护和改善环境，促进社会经济健康、和谐、稳定的发展。

1999 Air conditioning has also grown rapidly in commercial buildings From 1970 to 1995 the percentage of commercial buildings with air conditioning increased from 54 to 73 Jackson and Johnson 1978 and DOE 1998Air conditioning in buildings is usually accomplished with the use of mechanical or heat-activated equipment In most applications the air conditioner must provide both cooling and dehumidification to maintain comfort in the building Air conditioning systems are also used in other applications such as automobiles trucks aircraft ships and industrialfacilities However the description of equipment in this chapter is limited to those commonly used in commercial and residential buildings Commercial buildings range from large high-rise office buildings to the corner convenience store Because of the range in size and types of buildings in the commercial sector there is a wide variety of equipment applied in these buildings For larger buildings the air conditioning equipment is part of a total system design that includes items such as a piping system air distribution system and cooling tower Proper design of these systems requires a qualified engineer The residential building sector is dominatedby single family homes and low-rise apartmentscondominiums The cooling equipment applied in these buildings comes in standard packages that are often both sized and installed by the air conditioning contractor The chapter starts with a general discussion of the vapor compression refrigeration cycle then moves to refrigerants and their selection followed by packaged Chilled Water Systems11 Vapor Compression CycleEven though there is a large range in sizes and variety of air conditioning systems used in buildings most systems utilize the vapor compression cycle to produce the desired cooling and dehumidification This cycle is also used for refrigerating and freezing foods and for automotive air conditioning The first patent on a mechanically drivenrefrigeration system was issued to Jacob Perkins in 1834 in London and the first viable commercial system was produced in 1857 by James Harrison and DE SiebeBesides vapor compression there are two less common methods used to produce cooling in buildings the absorption cycle and evaporative cooling These are described later in the chapter With the vapor compression cycle a working fluid which is called the refrigerant evaporates and condenses at suitable pressures for practical equipment designsThe four basic components in every vapor compression refrigeration system are the compressor condenser expansion device and evaporator The compressor raises the pressure of the refrigerant vapor so that the refrigerant saturation temperature is slightly above the temperature of the cooling medium used in the condenser The type of compressor used depends on the application of the system Large electric chillers typically use a centrifugal compressor while small residential equipment uses a reciprocating or scroll compressorThe condenser is a heat exchanger used to reject heat from the refrigerant to a cooling medium The refrigerant enters the condenser and usually leaves as a subcooled liquid Typical cooling mediums used in condensers are air and water Most residential-sized equipment uses air as the cooling medium in the condenser while many larger chillers use water After leaving the condenser the liquid refrigerant expands to a lowerpressure in the expansion valveThe expansion valve can be a passive device such as a capillary tube or short tube orifice or an active device such as a thermal expansion valve or electronic expansion valve The purpose of the valve is toregulate the flow of refrigerant to the evaporator so that the refrigerant is superheated when it reaches the suction of the compressor At the exit of the expansion valve the refrigerant is at a temperature below that of the medium air or water to be cooled The refrigerant travels through a heat exchanger called the evaporator It absorbs energy from the air or water circulated through the evaporator If air is circulated through the evaporator the system is called a direct expansion system If water is circulated through the evaporator it is called a chiller In either case the refrigerant does not make direct contact with the air or water in the evaporatorThe refrigerant is converted from a low quality two-phase fluid to a superheated vapor under normal operating conditions in the evaporator The vapor formed must be removed by the compressor at a sufficient rate to maintain the low pressure in the evaporator and keep the cycle operating All mechanical cooling results in the production of heat energy that must be rejected through the condenser In many instances this heat energy is rejected to the environment directly to the air in the condenser or indirectly to water where it is rejected in a cooling tower With someapplications it is possible to utilize this waste heat energy to provide simultaneous heating to the building Recovery of this waste heat at temperatures up to 65°C 150°F can be used to reduce costs for space heatingCapacities of air conditioning are often expressed in either tons or kilowatts kW of cooling The ton is a unit of measure related to the ability of an ice plant to freeze one short ton 907 kg of ice in 24 hr Its value is 351 kW 12000 Btuhr The kW of thermal cooling capacity produced by the air conditioner must not be confused with the amount of electrical power also expressed in kW required to produce the cooling effect21 Refrigerants Use and SelectionUp until the mid-1980s refrigerant selection was not an issue in most building air conditioning applications because there were no regulations on the use of refrigerants Many of the refrigerants historically used for building air conditioning applications have been chlorofluorocarbons CFCs and hydrochlorofluorocarbons HCFCs Most of these refrigerants are nontoxic and nonflammable However recent US federal regulations EPA 1993a EPA 1993b and international agreements UNEP 1987 have placed restrictions on the production and use of CFCs and HCFCs Hydrofluorocarbons HFCs are now being used in some applications where CFCs and HCFCs were used Having an understanding of refrigerants can helpa building owner or engineer make a more informed decision about the best choice of refrigerants for specific applications This section discusses the different refrigerants used in or proposed for building air conditioning applications and the regulations affecting their use The American Society of Heating Refrigerating and Air Conditioning Engineers ASHRAE has a standard numbering systemfor identifying refrigerants ASHRAE 1992 Many popular CFC HCFC and HFC refrigerants are in the methane and ethane series of refrigerants They are called halocarbons or halogenated hydrocarbons because of the presence of halogen elements such as fluorine or chlorine King 1986 Zeotropes and azeotropes are mixtures of two or more different refrigerants A zeotropic mixture changes saturation temperatures as it evaporates or condenses at constant pressure The phenomena is called temperature glide At atmospheric pressure R-407C has a boiling bubble point of –44°C –47°F and a condensation dew point of –37°C –35°F which gives it a temperature glide of 7°C 12°F An azeotropic mixture behaves like a single component refrigerant in that the saturation temperature does not change appreciably as it evaporates or condenses at constant pressure R-410A has a small enough temperature glide less than 55°C 10°F that it is considered a near-azeotropic refrigerant mixture ASHRAE groups refrigerants by their toxicity and flammability ASHRAE 1994 Group A1 is nonflammable and least toxic while Group B3 isflammable and most toxic Toxicity is based on the upper safety limit for airborne exposure to the refrigerant If the refrigerant is nontoxic in quantities less than 400 parts per million it is a Class A refrigerant If exposure to less than 400 parts per million is toxic then the substance is given the B designation The numerical designations refer to the flammability of the refrigerant The last column of Table com shows the toxicity and flammability rating of common refrigerantsRefrigerant 22 is an HCFC is used in many of the same applications and is still the refrigerant of choice in many reciprocating and screw chillers as well as small commercial and residential packaged equipment It operates at a much higher pressure than either R-11 or R-12 Restrictions on the production of HCFCs will start in 2004 In 2010 R-22 cannot be used in new air conditioning equipment R-22 cannot be produced after 2020 EPA 1993bR-407C and R-410A are both mixtures of HFCs Both are considered replacements for R-22 R-407C is expected to be a drop-in replacement refrigerant for R-22 Its evaporating and condensing pressures for air conditioning applications are close to those of R-22 Table com However replacement of R-22 with R-407C should be done only after consulting with the equipment manufacturer At a minimum the lubricant and expansion device will need to be replaced The first residential-sized air conditioning equipment using R-410A was introduced in the US in 1998 Systems usingR-410A operate at approximately 50 higher pressure than R-22 Table com thus R-410A cannot be used as a drop-in refrigerant for R-22 R-410A systems utilize compressors expansion valves and heat exchangers designed specifically for use with that refrigerantAmmonia is widely used in industrial refrigeration applications and in ammonia water absorption chillers It is moderately flammable and has a class B toxicity rating but has had limited applications in commercial buildings unless the chiller plant can be isolated from the building being cooled Toth 1994 Stoecker 1994 As a refrigerant ammonia has many desirable qualities It has a high specific heat and high thermal conductivity Its enthalpy of vaporization is typically 6 to 8 times higher than that of the commonly used halocarbons and it provides higher heat transfer compared to halocarbons It can be used in both reciprocating and centrifugal compressorsResearch is underway to investigate the use of natural refrigerants such as carbon dioxide R-744 and hydrocarbons in air conditioning and refrigeration systems Bullock 1997 and Kramer 1991 Carbon dioxide operates at much higher pressures than conventional HCFCs or HFCs and requires operation above the critical point in typical air conditioning applications Hydrocarbon refrigerants often thought of as too hazardous because of flammability can be used in conventional compressors and have been used in industrial applications R-290 propane has operatingpressures close to R-22 and has been proposed as a replacement for R-22 Kramer 1991 Currently there are no commercial systems sold in the US for building operations that use either carbon dioxide or flammable refrigerants31 Chilled Water SystemsChilled water systems were used in less than 4 of commercial buildings in the US in 1995 However because chillers are usually installed in larger buildings chillers cooled over 28 of the US commercial building floor space that same year DOE 1998 Five types of chillers are commonly applied to commercial buildings reciprocating screw scroll centrifugal and absorption The first four utilize the vapor compression cycle to produce chilled water They differ primarily in the type of compressor used Absorption chillers utilize thermal energy typically steam or combustion source in an absorption cycle with either an ammonia-water or water-lithium bromide solution to produce chilled water32 Overall SystemAn estimated 86 of chillers are applied in multiple chiller arrangements like that shown in the figure Bitondo and Tozzi 1999 In chilled water systems return water from the building is circulated through each chiller evaporator where it is cooled to an acceptable temperature typically 4 to 7°C 39 to 45°F The chilled water is then distributed to water-to-air heat exchangers spread throughout the facility In theseheat exchangers air is cooled and dehumidified by the cold water During the process the chilled water increases in temperature and must be returned to the chiller sThe chillers are water-cooled chillers Water is circulated through the condenser of each chiller where it absorbs heat energy rejected from the high pressure refrigerant The water is then pumped to a cooling tower where the water is cooled through an evaporation process Cooling towers are described in a later section Chillers can also be air cooled In this configuration the condenserwould be a refrigerant-to-air heat exchanger with air absorbing the heat energy rejected by the high pressure refrigerantChillers nominally range in capacities from 30 to 18000 kW 8 to 5100 ton Most chillers sold in the US are electric and utilize vapor compression refrigeration to produce chilled water Compressors for these systems are either reciprocating screw scroll or centrifugal in design A small number of centrifugal chillers are sold that use either an internal combustion engine or steam drive instead of an electric motor to drive the compressorThe type of chiller used in a building depends on the application For large office buildings or in chiller plants serving multiple buildings centrifugal compressors are often used In applications under 1000 kW 280 tons cooling capacities reciprocating or screw chillers may be moreappropriate In smaller applications below 100 kW 30 tons reciprocating or scroll chillers are typically used33 Vapor Compression ChillersThe nominal capacity ranges for the four types of electrically driven vapor compression chillers Each chiller derives its name from the type of compressor used in the chiller The systems range in capacities from the smallest scroll 30 kW 8 tons to the largest centrifugal 18000 kW 5000 tons Chillers can utilize either an HCFC R-22 and R-123 or HFC R-134a refrigerant The steady state efficiency of chillers is often stated as a ratio of the power input in kW to the chilling capacity in tons A capacity rating of one ton is equal to 352 kW or 12000 btuh With this measure of efficiency the smaller number is better centrifugal chillers are the most efficient whereas reciprocating chillers have the worst efficiency of the four types The efficiency numbers provided in the table are the steady state full-load efficiency determined in accordance to ASHRAE Standard 30 ASHRAE 1995 These efficiency numbers do not include the auxiliary equipment such as pumps and cooling tower fans that can add from 006 to 031 kWton to the numbers shownChillers run at part load capacity most of the time Only during the highest thermal loads in the building will a chiller operate near its rated capacity As a consequence it is important to know how the efficiency of the chiller varies with part load capacity a representative data for theefficiency in kWton as a function of percentage full load capacity for a reciprocating screw and scroll chiller plus a centrifugal chiller with inlet vane control and one with variable frequency drive VFD for the compressor The reciprocating chiller increases in efficiency as it operates at a smaller percentage of full load In contrast the efficiency of a centrifugal with inlet vane control is relatively constant until theload falls to about 60 of its rated capacity and its kWton increases to almost twice its fully loaded valueIn 1998 the Air Conditioning and Refrigeration Institute ARI developed a new standard that incorporates into their ratings part load performance of chillers ARI 1998c Part load efficiency is expressed by a single number called the integrated part load value IPLV The IPLV takes data similar to that in Figure com and weights it at the 25 50 75 and 100 loads to produce a single integrated efficiency number The weighting factors at these loads are 012 045 042 and 001 respectively The equation to determine IPLV isMost of the IPLV is determined by the efficiency at the 50 and 75 part load values Manufacturers will provide on request IPLVs as well as part load efficienciesThe four compressors used in vapor compression chillers are each briefly described below While centrifugal and screw compressors are primarily used in chiller applications reciprocating and scrollcompressors are also used in smaller unitary packaged air conditioners and heat pumps34 Reciprocating CompressorsThe reciprocating compressor is a positive displacement compressor On the intake stroke of the piston a fixed amount of gas is pulled into the cylinder On the compression stroke the gas is compressed until the discharge valve opens The quantity of gas compressed on each stroke is equal to the displacement of the cylinder Compressors used in chillers have multiple cylinders depending on the capacity of the compressor Reciprocating compressors use refrigerants with low specific volumes and relatively high pressures Most reciprocating chillers used in building applications currently employ R-22Modern high-speed reciprocating compressors are generally limited to a pressure ratio of approximately nine The reciprocating compressor is basically a constant-volume variable-head machine It handles various discharge pressures with relatively small changes in inlet-volume flow rate as shown by the heavy line labeled 16 cylinders Condenser operation in many chillers is related to ambient conditions for example through cooling towers so that on cooler days the condenser pressure can be reduced When the air conditioning load is lowered less refrigerant circulation is required The resulting load characteristic is represented by the solid line that runs from the upper right to lower leftThe compressor must be capable of matching the pressure and flow requirements imposed by the system The reciprocating compressor matches the imposed discharge pressure at any level up to its limiting pressure ratio Varying capacity requirements can be met by providing devices that unloadindividual or multiple cylinders This unloading is accomplished by blocking the suction or discharge valves that open either manually or automatically Capacity can also be controlled through the use of variable speed or multi-speed motors When capacity control is implemented on a compressor other factors at part-load conditions need to considered such as a effect on compressor vibration and sound when unloaders are used b the need for good oil return because of lower refrigerant velocities and c proper functioning of expansion devices at the lower capacities With most reciprocating compressors oil is pumped into the refrigeration system from the compressor during normal operation Systems must be designed carefully to return oil to the compressor crankcase to provide for continuous lubrication and also to avoid contaminating heat-exchanger surfacesReciprocating compressors usually are arranged to start unloaded so that normal torque motors are adequate for starting When gas engines are used for reciprocating compressor drives careful matching of the torque requirements of the compressor and engine must be considered35 Screw CompressorsScrew compressors first introduced in 1958 Thevenot 1979 are positive displacement compressors They are available in the capacity ranges that overlap with reciprocating compressors and small centrifugal compressors Both twin-screw and single-screw compressors are used in chillers The twin-screw compressor is also called the helical rotary compressor A cutaway of a twin-screw compressor design There are two main rotors screws One is designated male and the other female The compression process is accomplished by reducing the volume of the refrigerant with the rotary motion of screws At the low pressure side of the compressor a void is created when the rotors begin to unmesh Low pressure gas is drawn into the void between the rotors As the rotors continue to turn the gas is progressively compressed as it moves toward the discharge port Once reaching a predetermined volume ratio the discharge port is uncovered and the gas is discharged into the high pressure side of the system At a rotation speed of 3600 rpm a screw compressor has over 14000 discharges per minute ASHRAE 1996 Fixed suction and discharge ports are used with screw compressors instead of valves as used in reciprocating compressors These set the built-in volume ratio the ratio of the volume of fluid space in the meshing rotors at the beginning of the compression process to the volume in the rotors as the discharge port is first exposed Associated with thebuilt-in volume ratio is a pressure ratio that depends on the properties of the refrigerant being compressed Screw compressors have the capability to operate at pressure ratios of above 201 ASHRAE 1996 Peak efficiency is obtained if the discharge pressure imposed by the system matches the pressure developed by the rotors when the discharge port is exposed If the interlobe pressure in the screws is greater or less than discharge pressure energy losses occur but no harm is done to the compressor Capacity modulation is accomplished by slide valves that provide a variable suction bypass or delayed suction port closing reducing the volume of refrigerant compressed Continuously variable capacity control is most common but stepped capacity control is offered in some manufacturers machines Variable discharge porting is available on some machines to allow control of the built-in volume ratio during operation Oil is used in screw compressors to seal the extensive clearance spaces between the rotors to cool the machines to provide lubrication and to serve as hydraulic fluid for the capacity controls An oil separator is required for the compressor discharge flow to remove the oil from the high-pressure refrigerant so that performance of system heat exchangers will not be penalized and the oil can be returned for reinjection in the compressorScrew compressors can be direct driven at two-pole motor speeds 50 or 60 Hz Their rotary motion makes these machines smooth running andquiet Reliability is high when the machines are applied properly Screw compressors are compact so they can be changed out readily for replacement or maintenance The efficiency of the best screw compressors matches or exceeds that of the best reciprocating compressors at full load High isentropic and volumetric efficiencies can be achieved with screw compressors because there are no suction or discharge valves and small clearance volumes Screw compressors for building applications generally use either R-134a or R-22中文译文空调系统过去 50 年以来空调得到了快速的发展从曾经的奢侈品发展到可应用于大多数住宅和商业建筑的比较标准的系统在 1970 年的美国 36

浅谈建筑环境与暖通空调节能
景观环境Landscape & Environment– 240 –随着暖通空调被广泛应用到我国人民的日常生活中，我国人民的生活质量显著提升，但是暖通空调的普及化应用造成了较大的能源供应压力，且暖通空调使用过程存在较严重的能源浪费问题，对我国社会经济稳定发展造成一定影响。
通过深入分析建筑环境与暖通空调节能，有利于找出更加可靠的措施使暖通空调节能水平得到提高，为我国社会发展奠定良好基础。
一、建筑环境对暖通空调节能的影响（一）室内环境对暖通空调的影响首先，在进行建筑设计过程中，需要合理设计建筑物体形系数及窗墙比，以此提高建筑物本身的节能性能。
通过正立面朝向、平面设计等建筑节能措施能够有效降低能源消耗，使暖通空调的负荷得到控制。
其次，为降低暖通空调的负荷，需要重视建筑朝向及建筑造型的设计，以此实现暖通空调的能源节约。
在进行建筑造型及平面设计时，需要利用南北通透、玻璃幕墙等各种方式提高建筑物的节能效果，使暖通空调的负荷得到降低。
最后，为居民构建舒适的居住环境，调节室内的气体流速、湿度、温度及热辐射是暖通空调的主要作用。
通过发挥建筑围护结构的热特性能，能够降低室外温度变化对室内环境的影响，进而使暖通空调的使用率得到控制。
（二）室内环境对暖通空调的影响为实现对暖通空调负荷的有效控制，需要充分了解室外环境对暖通空调的影响，其主要体现在以下几个方面：（1）气象条件对暖通空调的影响。
目前暖通空调包括了通风、采暖、空调等几个系统，这些系统对室外参数的要求不同，需要准确计算系统的负荷，为实现节能型的暖通空调提供有利依据。
（2）环境绿化对暖通空调的影响。
在建筑工程项目的建设过程中，普遍都会种植一些花草树木，既能够起到良好的环境美化作用，也能够起到一定的防辐射及吸热作用。
若是环境绿化达到要求，可以充分利用植物的吸热及隔热等作用，使暖通空调的负荷得到降低。
二、暖通空调实现节能的具体措施（一）降低空调新风系统的负荷新风量是暖通空调卫生健康标准的重要内容，一般空调新风系统的能耗占系统总能耗的30%左右，当新风量不断上升的时候，空调系统的能耗也就随之提高。

车辆工程技术163工程技术 目前，资源短缺问题已经成为人类必须面对的严峻挑战，社会的不断发展，带动了各个领域不同程度的发展，同时也增加了能源的使用与消耗量，造成能源消耗已经远远超过了能源再生以及收集的速度，能源紧缺问题日益严重。
为了实现可持续发展的目标，国家对不同领域的建设都提出了相应的节能要求，而作为能源消耗量较大的建筑行业也必须作出相应的节能措施，合理改善建筑环境，促进暖通空调实现节能环保的目标，从而为改善生态环境做出贡献。
1 建筑环境对暖通空调的影响1.1 建筑内部对暖通空调的影响 室内环境的舒适程度决定了人们使用暖通空调的使用量，因此通过内部结构的合理化设计，可以有效改善室内环境，从而减轻空调的负荷。

浅谈建筑环境与暖通空调节能发布时间：2021-07-20T17:10:40.403Z 来源：《工程管理前沿》2021年3月第8期作者：张志超1 冯珊珊2 [导读] 为提高暖通空调的节能水平，张志超1 冯珊珊2 身份证号码：23122219911207**** 身份证号码：44078519920504**** 摘要：为提高暖通空调的节能水平，本文就针对建筑环境对暖通空调节能的影响进行分析，并提出一些具体措施，希望能为暖通空调节能技术的发展提供有效参考依据。
关键词：建筑环境;暖通空调;节能 1 建筑环境对暖通空调节能的影响 1.1 室内环境的影响（1）室内温度，如果对暖通空调设定过高或过低的温度要求会直接造成电能的浪费，同时过大的室内外温差也容易使人们发生疾病，更会使得暖通空调长期处于大功率工作状态，因此无论是室内温度、湿度，还是室内气体的流动速度都要给人们一种舒适感;（2）建筑设计结构，应该在建筑设计时将建筑物的体形系数和窗墙比等参数严格控制在《公共建筑节能设计规范》的要求范围内，还要大面积减少围护结构去采用玻璃幕墙;（3）围护结构性能，屋顶与外界环境的接触面积大，不仅要做到防水，还要采用合适的材料隔热，墙体的主要作用是承重，可以利用复合墙体来节约一部分资源。
1.2 室外环境的影响建筑物所在的地理位置以及气候条件、周边绿化构成主要的室外环境，影响着暖通空调的节能減排效果，所以，设计人员在对建筑物设计过程中要充分考虑室外环境的各种因素，构建有利于暖通空调节能的有利条件。
①气候条件的控制对于建筑物暖通空调节能有着重要的影响，因此，选择拥有气候优势的地理位置对于建筑的建造也至关重要，每一个地理位置的气候都不相同，对于建筑物的作用也是影响较大。
我国的领土广阔，南北跨度大，气候条件的差异大，总体呈现南方潮湿，北方干燥的总体特点，特殊的地势有其自身特色，所以，对于气候条件的把握不容易，设计人员短时间内很难得出准确的结论，需要到当地进行实地的考察和分析，尤其利用好当地的优势环境条件，对适合该地的暖通空调进行设计。
