If you want to break this application limitation, it is required to use two-stage compressor or cascade system. Meanwhile, the working condition of high pressure ratio brings problems to the traditional single-stage compressors during compression process, such as excessive gas leakage and high exhaust temperature etc., which leads to low efficiency and poor reliability when it is working is such harsh conditions.The compound two-stage compressor well solves above problems. Compared with the two-stage compressors or cascade system, the compund two-stage compressors occupy less space and the system is easy to control, so it's more efficiency and reliable.LT Series compound two-stage compressor’s evaporation temperature can be as low as -60~-65°C , Its full load evaporating temperature can be -25°C, LT-S-L Series compound two-stage low temperature compressor is based on the LT-S series which modified the internal structure and optimized the motor matching to increase the compressor full-load evaporation temperature to -10 °C, So that LT-S-L series can meet the requirements of industrial refrigeration、quick freezing tunnel and freezing library without pre-coolingFor above reasons, Therefore The Shanghai Hanbell Precise Machinery Co., Ltd. developed the LT series high temperature compressors. High efficiency and reliability under big pressure differential and compression ratio working condition is the main demand in designing. It is a elitist product which accumulates Shanghai Hanbell's rich technology and extensive application experience. It can be widely used in many industries such as high temperature hot water, central heating and so on.2. Product Specification2.1 NomenclatureTable 2-1.LT series low temperature compressor nomenclature 2.2 Product LineTable 2-2.LT low temperature series product specification★2.3 Compressor specification tableTable 2-3.LT series compressor specification2.4Operating range graph图2-1. R22运行范围图图2-2.R404A运行范围图3.Construction & Functions3.1Design Features1）Starting loadStarting with light load; its starting load is similar to ordinary single stage compressor, so as to avoid greater impact on power grid.2）Motor cooling channelExcellent motor cooling channel design which ensures the high efficiency of the compressor, while realizing the reliable cooling of the motor, so that the compressor can operate in a very wide range, and a more extensive scope of application.3）integrated design of system partsPre-installed medium pressure check valves, shut off valves and economizer filters that ensure reliable protection of compressors and simplify customer system configuration.4）Motor temperature visualizationThe embedded temperature sensor of motor, PT100, PT1000 and NTC, are optional, which can directly read the motor temperature to control the motor temperature.3.2Capacity modulation systemLT series screw compressor is equipped with 3/4 step capacity modulation system or continuous (stepless) capacity modulation system.Both of the two capacity modulation systems are composed of slide valve, piston rod, piston cylinder and piston. As shown in Figure 3-1 below.When the spool is fully in contact with the suction side, the screw rotor is in full-load suction state, at which time the working volume of the compressor is maximized. As the spool is separated from the suction side, it moves toward the exhaust side. A bypass cavity is formed between the slider and the suction side.Its presence causes the compressed gas in this range to be bypassed directly to the low pressure, and the actual suction volume of the screw rotor is reduced.The more the slide valve moves toward the exhaust side, the smaller the actual suction volume of the compressor will be.And the system cooling capacity will also reduce The slide valve is driven by the pressure differential among the internal capacity modulation system.The lubricant comes from the external oil separator and passes through the oil filter then enters into the oil inlet port of the compressor, and at last divided to bothsides of the piston. As a result, the piston can be controlled by discharging the high pressure lubricant at one side to low pressure, letting it flow to the low pressure side so that the slide valve will move with the piston to realize the loading and unloading of the compressor.The purpose of the piston spring is to push the piston to its initial position (min. load position), so as to realize the automatic unloading start. It not only reduces the mechanical impact on the compressor's moving parts, but also reduces the electrical current during compressor start up.Stepless capacity control, solenoid valve(SV1:unloading, SV3:50%, SV5:100%) is controlled by a micro controller or a thermal switch to adjust the piston smoothly to stably control cold output. If the oil filter capillary or solenoid valve of the capacity modulation system don't work properly, it will cause the capacity modulation system to be abnormal and fail.Figure 3-1.Capacity Modulation System3.2.1 Step type capacity modulation system1） Step type control logicY: Energize the solenoid valve N: Do not energize the solenoid valveTable 3-1. Step Type Capacity Modulation Control Logic2） Step type capacity modulation graphFigure 3-2. Step Type Capacity Modulation3）Step type control logic description10% loadFigure 3-3. 10% LoadWhen starting up thecompressor, SV1(unload) &SV2 (10%) need to beenergized to make the pistonkeep at the 10% position(leftside)In this state, the highpressure oil passes throughSV1(unload) then goes to theright side of the piston. At thesame time, the oil from left side of the piston passes through SV2 (10%) then discharge to the low pressure side. By doing so, the piston can be held at the 10% load position.★ Note: 10% load is for start up only. Running the compressor at 10% load for a long time is not recommended.50% loadAt this time, the capacity adjustment solenoid valves SV1 (unload) and SV3 (50%) are active.Under 50% load, SV1(unload) &SV3 (50%) are energized.In this state, the high pressure oil passes to the left side of the piston continuously. At the same time, the oil passes through SV1 (unload) then goes to the right side of the piston.If the piston is at the left side of the 50% hole (the loading is less than 50%), the oil at the right side of the piston will pass through SV3 (50%) and discharge to the low pressure side then the piston will move to right side until the position blocks the 50% hole. Thus the compressor is loaded to 50% smoothly.Vice versa, if the piston is at the right side of the 50% hole (the loading is more than 50%), the oil in the left side of the piston will pass through SV3 (50%) and go out to the low pressure side then the piston will move to left until the position blocks the 50% hole. Thus the compressor is loaded to 50% smoothly.75% LoadUnder 75% load, SV1（unload）&SV4 (75%)are energized.The logic of 75% load issimilar to that of 50%. Thepiston can be held around75% position by 75% holeto make the compressorrun under 75% load.Figure 3-5.75% Load100%LoadUnder 100% load, SV5(100%) is energized. In this state,the high pressure oil passes to theleft side of the piston continuously.At the same time, the oil in theright side of the piston passesthrough SV5 (100%) then goes tothe low pressure side to make thepiston be held at 100% position.fig3-6.100% Load4） Step type capacity modulation and water temperature controlFigure 3-7.Step type capacity modulation and water temperature control★Note: T & T' should be adjusted by system designer’s experience and practical application.Time启动Set point + 2TSet point + TSet pointSet point – T'Storage temperaturet1 t21~3min 60~90 sec3.2.2Stepless type capacity modulation systemStepless type is suitable when the refrigeration system needs to achieve precise control of cooling capacity.1）Stepless type control logicTable 3-2. Stepless Type Capacity Modulation Control Logic 50%~100%2）Stepless type capacity modulation graphFigure 3-8.Stepless Type Capacity Modulation3）Stepless type control logic descriptionIn stepless type capacity modulation system, the oil keeps going to the left side of the piston. The oil bypass in the left side of the piston is controlled by SV3 (50%). The oil inlet in the right side of the piston is controlled by SV1 (unload) and oil bypass in the right side of the piston is controlled by SV5 (100%). These three solenoid valves are controlled by temperature controller or PLC.Through the three solenoid valves, the cooling capacity can be controlled at any position from 50%~100%, so through periodical adjustment of SV1、SV3、SV5, the energy output can controlled stably.★Note: SV2(10%) can only be used for machine start and stop. Don't run the machine at 10% load for long time once the machine is started. It shall be switched to load model directly.The stepless type capacity modulation system shall be connected to the micro controller(optional), eg. PLC etc. in order to control the system at the target working condition.LoadDuring load process, the SV5 (100%) adopts pulse activating, and the rest solenoid valve are not energized.In this kind ofsituation, the highpressure oil goes into theleft side of the pistoncontinuously and the oilin the right side of thepiston bypasses throughSV5 (100%) to the lowpressure side.The piston willcontinue to move to theright side and thecompressor completeload process.Figure 3-9. LoadUnloadDuring unload process,the SV2(50%) stays active,and SV1 (unload) adopts pulseactivating, and the restsolenoid valve are notenergized.The high pressure oilcontinues to go to the left sideof the piston and goes into theright side of the piston passingthrough SV1(unload).Through SV3(50%), it Figure 3-10. Unload bypasses to the low pressure side, so that the piston continues to move to the left side, and the compressor will load to 50% piston.Keep load stateFigure 3-11. Keep Load StateDuring this process, all S/V are not energized. The high pressure oil coming continues to go to the left side of the piston. The left side oil inlet of the piston SV1(unload) and SV5(100%) are closed to keep the oil amount in the right side of the piston. The piston will not be able to move and stay at its original position, so that the compressor capacity will not change as well.Stepless type capacity modulation and water temperature controlBelow picture shows the load control of single compressor in the application of stepless type capacity modulation.Figure 3-12. Stepless Type Capacity Modulation★Note ：X ′Upper Limit ；X 〞Lower Limit ；X Set Point ；H Control Range ；Y Actual valve❆ Description:● The actual water temperature exceeds the upper limit between A & B. Itmeans the compressor ought to unload until the actual value is within the control range.● The real value is smaller than the bottom line between C & D. It means therequired cooling capacity is decreasing and the compressor needs to be unloaded until the real value returns to the control range.Figure 3-13.

Hanbell designs for LT compressor the function of unloading startup. To ensure compressor loads steadily, please follow Figure 3-16 to load step by step during the whole loading process.When compressor is about to shut down, it is also required to unload to ensure that the slide valve is at lowest loading position during next startup and compressor could have an unloading startup. Thus Hanbell requires no matter what load condition of the compressor is, it should be unloaded step by step till minimum load before stop according to below Figure 3-16.Figure 3-16. Compressor Startup and Stop ProcessCaution：1）A fter startup, keep the minimum load for 10 seconds. Before shut down, keep the minimum load for 30 seconds(Time can be set to 10~60seconds).2）A fter startup, when the pressure difference between high pressure and middle pressure is less than 3.5bar, the compressor shall be run at 10% load at low pressure stage. Don't load and open ECO.3）t=30 seconds(Time can be set to 30~60seconds).4）A fter the compressor shut down, the SV1 (unload) & SV2(10%) need to be still energized for 3 minutes, so as to ensure the compressor can still at min load position at next startup.5）H anbell strongly recommends that the compressor start-up and shutdown control logic shall refer to above graph. For detail informationplease refer to the regulations written in LT-S Control Requirements.4.LubricantTable 4-1. Lubricant SpecificationCaution:1）P lease refer to the table above to select the suitable lubricant and refrigerant and its operation range need to be taken into consideration as well.2）H anbell strongly recommends do not use the lubricant which isn’t certified by Hanbell since it may damage the compressor seriously.3）T his specification table is for LT series compressors only.4）T he oil temperature at the point when the compressor starts is suggested to be 5K higher than the corresponding saturation temperature of the oil separator in order to avoid too much oil containing in the refrigerant which may affect the lubricant. 5）A fter compressor stops, please turn on the oil heater of the external oil separator.If the compressor shuts down for a long time, please turn off the oil heater. Please heat the lubricant for more than 2 hours before next start up.1）B e sure to make the system clean and no welding spatter and other impurities before lubricant filling2）I n order to ensure that the system is dry enough, it should be dehumidified before filling. It is advisable to fill the system with dry nitrogen first and then vacuum the system. The vacuum time should be as long as possible. It is strongly recommended to repeat the above steps several times to minimize the water contained in the system.Caution1）D o not use the lubricant which is not approved by Hanbell, otherwise it may causeserious damage to the compressor2）D o not mix different brands of lubricants, otherwise they may cause serious damage to the compressor. Pay attention to it when replacing lubricating oil for the system.4.2The Replacement of Lubricant4.3.1Oil Change Schedule1）C heck lubricant every 10,000 hours after continuous running. For the first operation of the compressor, it is recommended to change the oil and clean the external oil filter after running 2,000 hours. Check the system whether clean or not and then change oil every 20,000 hours or after 4 years continuous running if the system operates in good condition.2）T he oil will deteriorate if the compressor runs at high discharging temperature (above 95℃) in the long term. Please avoid this situation, but if it’s necessary to run in this condition, please shorten the intervals of oil changing.4.3.2Pre-cautions for changing oil1）I t is recommended to check the quality of oil periodically in order to maintain the lubrication performance.2）T he lubricant absorbs moisture in the air. Avoid to expose it to the air for a long timeIf the compressor motor is burned, the acid and harmful substances and burned debris will be brought into the system. Therefore, the oil filters and lubricants must be replaced repeatedly. It is suggested to replace the lubricating oil again after 72 hours of operation until the quality of the lubricating oil in the system returns to standard valve.3）T he foreign body in the oil will block the oil line, so it is necessary to install an oil filter in the external oil line. Also, the pressure differential sensor need to be installed before and after the oil filter. If the pressure differential valve between these two sensors reaches 1.5 bar, the oil filter need to be changed.4）T he acidity of oil will directly affect the life of the motor, and it is recommended to change the oil when PH≤6. (Please also change the filter drier at the same time to make sure the system is dry.）5）I t is important to replace the oil, especially when the motor is burnt because the acidity remains in the system. By replacing the oil can help check the status of thesystem. Check the acidity of the lubricant, and re-change the oil after the system runs for 72 hours until the acidity of the lubricant reaches the standard valve.6）I n case of motor burned out, please not only change the compressor, but also change the oil and check the condition of the oil periodically. If the acidity excesses the standard, please change it immediately and always be aware of the cleanliness and moisture contained in the system.5. System Application★Note ：Please consult Hanbell for parallel application and heat pump application.5.1 Piping Design5.1.1 Suction and Discharge Piping Layout1）Material and structure of suction and discharge pipeThe vibration of the compressor is small in normal operation, so it is not necessary to use flexible joints for suction and discharge tubes, but the pipes need to have enough flexible length to ensure the suction and discharge pipes won't cause any stress to the compressor. It is recommended to use copper tube for the suction and discharge piping in order to decrease the piping vibration when the compressor is in operation.2）The dimensions of suction and discharge piping:It is suggested to design the dimension of suction and discharge piping according to Hanbell recommendation (refer to 10.2.2).3）Piping for parallel systemTo improve the system operation efficiency, it’s necessary to reduce the gas -flow resistance and consider the oil return of suction piping. The recommended piping of suction and discharge side for parallel system is shown below:Be aware of the area of the main pipe should not be less than the area of the other pipes to make sure the pressure drops could be controlled in reasonable range. ❆ Piping at discharge side❆ x x xFigure 5-2 Suction Piping for Parallel SystemDetail Drawing 2 4) Suction filterThis model of compressor has a built-in suction filter, but it is only used as a final protection. It should not be used as an suction filter that needs to be cleaned regularly.So It is necessary to install a suction filter (25μm) which is easy to remove and clean it regularly.When the system is first used, it may need to be cleaned up frequently. If the pressure drop is bigger than 0.5 bar, the filter element should be replaced or cleaned until the system is clean. When the filter is disassembled, if the filter is found to be damaged, it needs to be replaced in time, and the impurities in the pipeline should be cleaned up. Ensure that the filter is oriented correctly during installation and it is recommended to add a shut-off valve at the inlet and outlet for easy maintenance.Hanbell The recommended suction filter design is shown in Figure 5-3 below.Figure 5-3.suction filterx xx Detail Drawing 2★Note：External suction filter should be used for cryogenic refrigeration systems。

所有这两种谐波都会对发电机造成损坏。
显然，由于输入滤波器的引入，大大地改善UPS的输入电源供电质量。
2.整流器/充电器9315系列UPS采用微处理器控制的三相全桥可控硅式整流桥，其微处理器芯片采用16位80C166，该芯片除精确控制整流桥外，还与其它控制电路的CPU形成通信网络(HAWKNET )，进行快速的信息传递，通信频率高达300K 。

整流器的保护功能有：三级输入电流限制，线性输入电流“爬升”特性，初始磁化电流限流，高阻接地保护电路。
三级输入电流限制：在正常工作时，整流器可供125％满负荷电流，并限定在125％，防止更大的电流损坏元器件。
在发电机给UPS供电时，输入电流限流值会自动变小，以保护发电机。
其大小可在43％－125％范围选择设定。
一旦发电机退出，限制值又会自动返回到125％。
UPS工作在旁路方式时，整流器输入电流的限流值会自动地变为更小值，以防止产生过大的充电电流而损坏电池。
限流值可在6％－34％范围选定。
一旦UPS带载，电流限制值会自动回复到设定的额定工作电流数值。
线性输入“爬升”特性：在市电输入加电后，为使UPS逐渐承担负荷，在整流器的控制电路中设有输入“爬升”电路，直流电压的“爬升”时间为4－6秒，一旦升至电池合闸电压，电流将以每秒10％满负荷电流的速率增加。
高阻接地保护电路，以检测电池对地之间泄漏电流。
