Experimental study on joint heating performance of double-cold-source fresh air unit and metal radiant panels

In view of the current situation that few researches on the operational characteristics of dual-cold source fresh air dehumidifier and radiant panel combined refrigeration systems in the office were carried out，a test platform for metal radiant panel and dual-cold source fresh air dehumidifier was built，the heating operation status of the metal radiant panel and dual-cold source fresh air dehumidifier air-conditioning system was tested，and the heating performance of the dual-cold source fresh air dehumidifier and air source heat pump and indoor temperature distribution characteristics and indoor air quality were tested in detail.The results show that after 8 hours of operation of the metal radiant panel and dual-cold source fresh air dehumidifier air-conditioning system，the air temperature of the air outlet fluctuates at about 22 ℃，and the moisture content is 7 g/kg；While the indoor heat and humidity demand is achieved，the temperature distribution in vertical direction is uniform and the indoor temperature difference in vertical direction is 0.89 ℃/m；And the indoor air quality is good，concentration of CO_2 continuously dropsto 433 mg/L，and the concentration of indoor PM2.5 drops to 10 μg/m~3.The research results have a certain reference value for the in-depth study of the heating effect of the combined operation of the metal radiant panel and the dual-cold source fresh air dehumidifier and the engineering application of the system in areas hot in summer and cold in winter.
