摘　　要：为解决农村采暖问题,设计了一种太阳能/直蒸式水源热泵耦合供暖系统;该系统日间利用太阳能供暖,同时将热量储存在蓄热水箱中;夜间采用水-冰相变释放的潜热供暖。实验结果显示:该系统在直蒸式水源热泵进口温度为15℃时的制热能效比COP为4.5;在直蒸式水源热泵出口温度为0℃时的制热能效比COP为2.9;系统性能稳定,水源热泵进口温度在-5~15℃的运行良好。经济性分析结果显示;该系统的运行费用较低。以期为河北省南部地区乡镇住宅采暖提供技术可靠、供暖稳定、初装成本较低的新型供暖系统。In order to solve the problem of rural heating,a solar energy/direct steaming water source heat pump coupling heating system is designed,which uses solar heating during the day,while heat is stored in the heat storage water tank,and latent heat released by the water-ice phase is used for heating at night.Experiment results show that the system has a thermal energy efficiency ratio(COP)is 4.5 when the inlet water temperature of direct steaming water source heat pump is 15℃,and COP is 2.9 when the outlet water temperature of direct steaming water source heat pump is 0℃.The system is stable and the water source heat pump operates well at the inlet temperature of-5~15℃.The economic analysis shows that the operating cost of the system is low.It provides a new heating system with reliable technology,stable heating and low initial installation cost for townships residential heating in southern Hebei Province.
