Experimental study on heating characteristics of radiant air conditioning system
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.
