辐射空调系统供暖特性试验研究

Experimental study on heating characteristics of radiant air conditioning system

为探究辐射空调系统供暖特性,搭建辐射空调系统试验台,进行7 d的系统间歇运行试验,对两级新风机组送风温湿度,空气源热泵主机制热量、能效比,以及系统能耗和能效比进行分析。结果表明,在设定参数下,两级新风机组稳定时送风温湿度分别为27℃和35%左右,空气源热泵主机平均制热量为4.5 kW,制热性能系数(COPU)为4.10;辐射空调系统耗电量为1.5 kW·h,系统性能系数(COPS)为3.02。试验结果可为系统的进一步优化和推广提供参考。

To explore the heating characteristics of a radiation air conditioning system,a radiation air conditioning system test bench was built,a 7-day intermittent operation test was conducted.The temperature and humidity of the air from two-stage fresh air unit,the heat output and efficiency of the air-source heat pump,as well as the energy use and efficiency ratio of the system were analyzed emphatically.The results show that under setting parameters,the stable supply air temperature and humidity of the two-stage fresh air are about 27℃and 35%,respectively.The average heating capacity of the air source heat pump host is 4.5 kW,and the heating coefficient of performance(COPU)is 4.10.The power consumption of the radiation air conditioning system is 1.5 kW·h,and the system coefficient of performance(COPS)is 3.02.The results can provide reference for further optimization and promotion of the system.
