Thermal comfort of refrigerant radiant cooling systems

Taking a sample office in Zhengzhou with a refrigerant radiant cooling system as an example, simulates the indoor temperature, the velocity field, the relative humidity field and the cloud distribution of PMV and PPD under the standard cooling condition of heat pump and the evaporate capillary coil spacing of 100 mm with Airpak3.0 software. Verifies the reliability of the simulation results with experimental data. The simulation results show that adopting the refrigerant radiant cooling system, the indoor occupants’ comfort requirements could be satisfied in the zone of over 0.36 m of the floor.
