冰蓄冷空调“除热量”分析

本文对除热量的构成进行了讨论,并对冷冻水、楼板和内墙造成的除热量的逐时分布进行了估算,用某大厦空调运行的实测数据进行了验证。理论计算和实测数据表明,空调运行的开始阶段除热量数值比较大,甚至为主要空调冷负荷,认为除热量对冰蓄冷空调有着重要的影响,就建立在科学基础上的冰蓄冷空调技术而言,在进行负荷计算时,必须要对除热量予以适当的考虑。

Analysis to the heat extraction rate of cool storage air conditioning system

In this paper, the component part of heat extraction rate is discussed, and the distributing time by time of heat extraction rate which caused by cool water, floors and inside walls of a building are evaluated and which verified with testing data to operating of air conditioning system in a building. And theory calculation and testing data indicate that heat extraction rate is larger in early stage of air conditioning system operating, and even is major cool load of a building. And writers consider that heat extraction rate has important effect to a cool storage air conditioning system which must based on a scientific fact, we must pay enough attention to the heat extraction rate of a building when its cool load is evaluated.
