水环热泵系统作为节能型空调系统的一种形式,近年在中国得到较多应用。对于近年有些工程提出了采用空气源热泵作为热源与水环热泵联合供暖的方式,本文依据生产厂家提供的技术参数,拟合出空气源热泵和水环热泵的COP性能曲线,对两种热泵联合运行供热时的系统性能系数COP进行了理论分析并用Maple软件进行模拟计算,得出联合运行系统与单独采用空气源热泵系统相比并不节能的结论。
Water ring heat pump system as a form of energy-saving air-conditioning system, in recent years in China have been more applications. Some projects in recent years proposed the use of air source heat pump as a heat source and water ring heat pump combined heating mode, this article based on the technical parameters provided by the manufacturer to fit the air source heat pump and water ring heat pump COP performance curve, the two heat pump The system performance coefficient COP at heating operation is theoretically analyzed and simulated by Maple software. The conclusion is that the combined operation system is not energy saving when compared with the air source heat pump system alone.
