Experimental Study on Coupled Heat Pump Heating System with Water Phase-Change Energy and Air-Source Dual Heat Sources
摘要
Abstract
A coupled heat pump heating system with water phase-change energy and air-source dual heat sources was designed,and three heat extraction meth-ods of the heat extraction unit were analyzed.Taking an office building as the heating target,experimental methods were employed to test and analyze indoor tem-perature and heat pump unit heating performance coef-ficient under the three heat extraction methods.Method A:The shell-type phase-change heat exchanger operates independently.Method B:The finned-tube air-cooled heat exchanger operates inde-pendently.Method C:The shell-type phase-change heat exchanger and finned-tube air-cooled heat exchanger operate in a coupled manner.When the out-door temperature ranges from-6 to-1 ℃,Method B fails to meet the minimum indoor temperature require-ments,while Methods A and C satisfies the minimum indoor temperature requirements.Compared with Method A,Method C presents a slightly lower average indoor temperature but a higher average heating COP of the heat pump unit.For Method B,the outdoor tem-perature exerts a significant impact on the performance of the heat pump unit,and the unit still fails to meet the minimum indoor temperature demand at an outdoor temperature of-6 to-1 ℃.When the outdoor tempera-ture is relatively low,Methods A and C are recom-mended for adoption.When assessing the operation performance of the heat pump unit,it is not feasible to rely solely on the heating COP,and the indoor tempera-ture should also be taken into full account.关键词
