摘　　要：数据中心是当前节能工作重点,其新风系统节能较为重要。常规数据中心采用低温盘管除湿和后端加湿的系统,浪费能源于恒温恒湿,且无法有效利用室外免费冷源。本文介绍数据中心双冷源恒温恒湿新风机组的系统原理,并以某实际工程案例为例介绍系统配置,末端设计和运行策略,并分析COP及PUE,认为此技术具有明显的节能效果。Data center is the key point of current energy saving work in which the energy saving of its fresh air system is more important.The conventional data center adopts the system of low-temperature coil dehumidification and terminal humidification.It not only leads to energy consumption for constant temperature and humidity,but also cannot effectively use the outdoor free cold source.This paper introduces the principle of a dual-cooling sources fresh air system in data center which can maintain constant temperature and humidity.Through a practical engineering case,it introduces the system configuration,terminal design and operation strategy.By analyzing COP and PUE,it is considered that this technology has the obvious effect on energy saving.
