摘要
数据中心较常规舒适性空调系统拥有小焓差大风量低湿负荷高显热比等负荷特点,所以相对于常规的7℃/12℃和32℃/37℃的空调水温设计,采用大温差和提高冷冻水供水温度的方式,十分有利于降低数据中心暖通系统全年能耗,提高PUE。
Compared with the conventional comfort air conditioning system, the data center has the characteristics as follows: Small enthalpy and strong wind, low humidity load and high Sensible heat factor. Therefore, compared with the conventional water temperature design such as 7℃/12℃ and 32℃/37℃, large supply/return water temperature difference technology and Increased supply Water Temperature is very beneficial to reduce the annual energy consumption of the data center HVAC system and improve PUE.
