Design practice and analysis of heat-source-tower heat pump air conditioning in hospital buildings
摘要：
以夏热冬冷地区某医院建筑为例,采用HDY-SMAD软件计算了空调冷热负荷及全年动态负荷,通过方案对比,确定了采用热回收型热源塔热泵机组作为空调系统的冷热源,介绍了热源塔热泵空调系统的设计、选型、控制及运行维护。结合实测数据,分析了热源塔热泵机组的实际运行能效,总结了热源塔热泵空调系统的设计要点。
Abstract：
Taking the construction of a hospital in the hot summer and cold winter zone as an example, the HDY-SMAD software is used to calculate the heating and cooling loads, as well as the annual dynamic loads. Through comparison of the schemes, it is determined to use a heat recovery type heat-source-tower heat pump unit as the cold and heat source for the air conditioning system. The design, selection, control, and operation maintenance of the heat-source-tower heat pump air conditioning system are presented. Based on the actual measurement data, the practical operating efficiency of the heat-source-tower heat pump unit is analysed, and the key design points of the heat-source-tower heat pump air conditioning system are summarized.
