深圳地区办公建筑供冷季空调系统综合能耗分析

Analysis on Comprehensive Energy Consumption of Air Conditioning System for Office Building of Shenzhen in Cooling Season

采用鸿业全年负荷计算及能耗分析软件HY-EP 5.0,选用中国标准年(CSWD)气象数据,对深圳某办公建筑进行了动态负荷计算,以《非供暖季不同末端空调系统综合能耗的计算分析方法浅析》一文中的计算分析方法对风机盘管、多联机、定风量空气处理机组和变风量空气处理机组4种不同的空调末端形式的供冷季空调系统综合能耗进行了计算分析,并将计算结果与办公楼的实际能耗进行了对比。结果表明,办公建筑多联机空调系统的空调综合能耗最低,变风量空气处理机组系统次之,其次是风机盘管系统,定风量空气处理机组系统最高;风机盘管系统计算值与实际值各月变化规律基本相同,计算值各月均比实际值略大,偏差在20%左右,说明此模拟计算方法是可靠的,模拟计算的结果是可信的。

The energy simulation HY - EP 5. 0 program is applied to simulate dynamic loads＇, using the China Standard Weather Database （CSWD） for input condition. An office building in Shenzhen is studied. The method mentioned in ＂Calculation Methods about Comprehensive Energy Consumption of Air Conditioning System by Different Terminal Units＇ in Non - heating Season＂ （ issued on Journal of ＂Building Energy Efficiency＂, 46（2）, 2018） is utilized to calculate and attalyze comprehensive energy consumption of air conditioning system by four terminal units＇ about fan - coil unit, multi - connected split unit, constant air volume system and variable air volume system in cooling season of a full year. The results showed that about comprehensive energy consumption of air conditioning system, multi - connected split unit is＇ the lowest, variable air volume system is the second, fan - coil unit is the third, constant air volume system is the highest. The change regulation about fan - coil unit air conditioning system of the calculated values and the actual values is largely the same in every months, and the calculated values is larger than the actual values, the deviation date is about 20%. The result shows that the method mentioned in ＂Calculation Methods＇ about Comprehensive Energy Consumption of Air Conditioning System by Different Terminal Units＇ in Non -heating Season＂ is reliable, and the calculated value is credible.
