摘要
提出利用相变蓄热供暖墙(墙体内空气源热泵冷凝器管作为发热体,相变材料作为蓄热体)为临时用房辐射供暖。在热泵开机阶段(8:00—17:00),供暖墙边供暖边蓄热(发热体放热的同时蓄热体蓄热)。在热泵停机阶段(17:00—次日8:00),蓄热体放热,以维持基础室内温度。模拟热泵开停机阶段室内温度,对供暖墙参数进行优化配置。热泵停机阶段仅采用供暖墙内蓄热体放热,可维持基础室内温度。热泵开机阶段,发热体温度越高,室内温度越高,相变材料完全熔化时间越短。在热泵开机的初始阶段室内温度偏低,为提高热舒适性,建议提前开启热泵。
It is proposed to use the phasechange heat storage heating wall(with air source heat pump condenser 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 startup phase of the heat pump(8:00-17:00),the heating wall supplies heat while storing heat(the heating element releases heat while the heat storage element 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 temperature.The indoor temperatures during the startup and shutdown stages of the heat pump are simulated to optimize the configuration of the heating wall parameters.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 indoor temperature.During the startup phase of the heat pump,the higher the temperature of the heating element,the higher the indoor temperature,and the shorter the complete melting time of the phase change material.During the initial stage of heat pump startup,the indoor temperature is low,and it is recommended to turn on the heat pump in advance to improve thermal comfort.
