空调冷负荷的计算分析

Analysis and Calculation of Air Conditioning Cooling Load

空调冷负荷计算是空调工程设计的基础,其计算结果决定着空调系统冷源及各末端设备的选配。采用鸿业负荷V6.2计算软件,选取4个不同功能公共建筑,计算了夏季逐时空调冷负荷,对计算结果进行分析得出:在夏季空调各项冷负荷中,新风冷负荷、人员冷负荷、围护结构冷负荷为冷负荷的主要组成部分;通常在人员密度较高、群集系数较大、人员劳动强度较高的房间,人体潜热负荷比重较大。进一步指出合理选择人员密度数值。

Air -conditioning cooling load calculation is the basis of air -conditioning engineering design, the result of calculation determines the selection of cold source of air conditioning system and all terminal equipment. By Hongye Load V6. 2 software, we selected four functions of public buildings to calculate the summer hourly air -conditioning cooling load, the calculating results show that fresh air cooling load, staff cooling load, and cooling load of retaining structure are main components in summer air-conditioning cooling load; usually, the proportion of human body heat load is larger in the room of larger personnel density, higher cluster coefficient and heavier labor intensity. The reasonable personnel density and fresh air volume standard are crucial to calculation of air -conditioning cooling load for public buildings in summer.
