Abstract

Taking the variable refrigerant flow (VRF)-based household radiant air-conditioning (A/C) system as the research object, this paper established the experimental test platform of the VRF-based household radiant A/C system in an existed psychometric room, simulated winter and summer operating conditions, and conducted a performance test study of the system, to verify the stability of the VRF-based household radiant A/C system and obtain the relationship between the parameters of the system and the outdoor air temperature. The experimental results showed that the VRF-based household radiant A/C system could operate stably in both winter and summer experimental conditions. In summer mode, the total cooling capacity (TCC) of the system increased by 31.32%, as the outdoor air temperature varied from 29 to 43 ℃. Also, the electric power consumption of the VRF outdoor unit increased by 45.4%, and the system EER decreased to a minimum of 3.55. In winter mode, when the outdoor air temperature changed from 7 to −5 ℃, the total heating capacity (THC) of the system increased by 27.70%, while the electric power consumption of the VRF outdoor unit increased by 42.41%, and the system COP decreased to a minimum of 3.48.
