Abstract
In view of the high energy consumption of heating and air conditioning in buildings, the study takes the unit radiation plate filled with Phase Change Material (PCM) as the research object, and proposes an energy storage scheme combining double-layer energy storage floor with ceiling-mounted energy storage radiant panel air conditioning to improve the utilization rate of valley electricity. Numerical simulation method is used to simulate the phase change heat transfer process, and the heat transfer characteristics of the phase change energy storage radiant air conditioning system under different ambient temperatures and indoor heat fluxes are studied. The results show that the floor surface can maintain a warm surface of 24–18 °C in the heat storage environment of 19 °C and the heat release environment of 12 °C in winter. And the floor surface can maintain a cool surface of 19–24 °C, and the radiant panel surface can maintain a cool surface of 18–23 °C in the cold storage environment of 26 °C and the cold release environment of 32 °C in summer. The system can not only meet the requirements of indoor heating and ventilation, but also alleviate the uncomfortable problem of rapid temperature change of radiant panel, and effectively solve the dewing problem of radiant panel.
