无水地暖热水两联供空气源热泵实验研究
Experimental Study on the Performance of Waterless Floor Heating and Hot Water Dual Supply Air-Source Heat Pump System
摘要
Abstract
A new type of air-source heat pump system is proposed,combining domestic hot water and waterless floor heating that is achieved by the direct condensation of the refrigerant in buried pipes.The high-temperature refrigerant is exchanged in the wrapped coil water heater to produce domestic hot water.The prototype was assembled and tested in three modes:standalone floor heating,dual supply,and standalone domestic hot water.The experimental results show that in all three cases,the surface temperature of the floor was maintained between 25℃and 33℃,and the air temperature was maintained between 18℃and 22℃.Due to the heat storage effect of the capillary floor,the air temperature in the room remained above 18℃within 113-245 min after terminating the system.At an ambient temperature of-5℃,after 572.3 min,the water temperature of the water heater rose to 45℃.The minimum system heating capacity and energy efficiency ratio(EER)can reach 2.70 kW and 3.55,respectively.关键词
