摘要

在能源短缺的今天，保持可持续发展，改善能源过度浪费的现状刻不容缓。本课题应对国内存在的机房降温系统的不足，设计了一套基于西门子LOGO!的机房空调节能控制系统。通过对室内温度，室外温度、湿度、粉尘度的采集和处理，智能控制空调和风机的启停，适宜的情况下优先使用风机利用室外冷源对机房进行降温，以减少空调的启动，达到节能降温的目的，同时也延长了空调设备的使用寿命。

系统中设置的参数主要有：室内温度，室外温度，室外粉尘高限，室内上限温度，室内下限温度，上限湿度，空调停机温度，警报温度，风机工作最低温度。全部参数均可以自定义设置，以满足在不同环境中更合理的控制要求。此外系统具有完善的警报触发机制，温度、湿度、粉尘度等一旦超出设定范围和出现设备故障则声光警报。

本系统稳定可靠，安装便捷。经过大量的调查统计，理论上在南方城市的车站机房中运行本系统每年可节省电能约20%。对于常年处在低温环境的北方城市来说效果将更加显著。

关键词：机房节能降温空调风机

Abstract

Energy shortage of today, to keep sustainable development, improve the status of excessive waste of energy is not a moment to hesitate. This topic against the insignificancy of the room cooling system , design a room air conditioning energy saving control system based on Siemens LOGO!.This system can intelligent control the air-conditioning and the fan start or stop,by collect and deal with the indoor temperature, outdoor temperature, humidity, dust degree,encounter suitable conditions this system can take precedence use of Fan to cool the engine room by the outdoor cold source,thus can not only reduce the start times of air conditioning to energy-saving cooling, but also extend the life of air-conditioning equipment.

System parameters set are: indoor temperature, outdoor temperature, outdoor dust, high limit, the indoor maximum temperature, minimum temperature indoors, limit humidity, air conditioning shutdown temperature, alarm temperature, fan working minimum temperature. You can customize all the parameters are set to meet in different environments more reasonable control requirements. Addition, the system has a complete alarm trigger mechanism, temperature, humidity, dust, etc. Once you exceed the set level range and equipment malfunctions make a sound and light alarm.

The system is reliable and easy to install. After extensive survey, theoretically station in the southern city of room to run this system annual energy savings of about 20%. For year-round in a low-temperature environment of the northern city, the effect will be more significant.

Keywords：machine room Energy-saving cooling air-conditioning fan
