摘　　要：为降低深圳市高层住宅集中式太阳能热水系统的能耗损失及运营成本,以某小区空气源热泵辅助太阳能集中热水系统为例进行能耗分析,进而对系统运行模式进行合理优化。通过实地调研提出目前深圳市集中式太阳能热水系统使用中存在的问题,分析系统单位热水能耗的组成,从能量平衡和能量转化的理论出发确定了热水用量、热水设定温度、系统热损失、集热系统集热效率和热泵机组热效率五个主要的影响因素。对深圳市某小区空气源热泵辅助加热太阳能热水系统进行运行监测,对比了模拟计算的系统能耗和实际能耗,并对系统的运行提出了优化建议。In order to reduce the energy consumption and operating costs of centralized solar energy hot water system in the high-rise residential in Shenzhen, take the air source heat pump assisted solar energy hot water system of a district as an example for analysis of energy consumption, and then optimize the system operation mode. Put forward the problems existing in the use of the centralized solar energy hot water system through the investigation in Shenzhen, then analyze the composition of the unit energy consumption of hot water, from the energy balance and energy conversion theory to determine the amount of hot water, hot water set temperature, the system heat losses, collection efficiency of solar collector system and thermal efficiency of the heat pump unit are five main factors. Operate and monitor the air source heat pump assisted solar energy hot water system of a district in Shenzhen, Compared the simulated energy consumption with the actual energy consumption and optimized the system.
