摘要
针对空气源热泵用于冬季供热时存在的不足及太阳能热泵应用特点,提出可同时利用空气和太阳能两种低位热源的复合热源热泵模式:制热工况时,该热泵机组有两个并联的蒸发器;制冷工况时,机组有两个并联的冷凝器。建立了复合源热泵系统的稳态仿真模型,对复合热源热泵机组样机进行了测试,模型分析和测试结果表明,复合源热泵机组的性能大大优于传统的风冷热泵机组。
In view of the disadvantages of the air source heat pump in heat supply and the characteristics of the application of solar energy heat pump, a compound source heat pump using air and solar energy as low-order heat source was put forward, which has two parallel evaporators under heating condition and two parallel condensers under refrigerating condition. The steady-state simulation model of compound source heat pump system was developed, and the performance test of compound source heat pump unit for heating and refrigerating was carried, which indicates that the performance of the compound source heat pump system is much better than that of the air source heat pump system in general.
