Abstract
It is proposed to use the phase-change heat storage heating wall(with air source heat pump con-denser tube inside the wall as the heating element and phase change material as the heat storage element)for the radiant heating of the temporary housing.During the start-up phase of the heat pump(8:00-17:00),the heating wall supplies heat while storing heat(the heat-ing element releases heat while the heat storage ele-ment stores heat).During the shutdown phase of the heat pump(17:00-8:00 the next day),the heat storage body releases heat to maintain the basic indoor tem-perature.The indoor temperatures during the start-up and shutdown stages of the heat pump are simulated to optimize the configuration of the heating wall param-eters.During the shutdown phase of the heat pump,only the heat storage element inside the heating wall is used to release heat,which can maintain the basic in-door temperature.During the start-up phase of the heat pump,the higher the temperature of the heating ele-ment,the higher the indoor temperature,and the shorter the complete melting time of the phase change material.During the initial stage of heat pump start-up,the indoor temperature is low,and it is recommended to turn on the heat pump in advance to improve thermal comfort.关键词
