THERMAL PERFORMANCE ANALYSIS OF A SOLAR HEATING AND NOCTURNAL RADIANT COOLING SYSTEM

摘要：

The solar heating and nocturnal radiant cooling techniques are united to produce a novel heating and cooling system. The HCPs (heating and cooling panels) can be used as structure materials for building envelope, which realizes the real building integration. Its thermal performance, namely heat-collecting capacity, heat-collecting efficiency and cooling capacity are analyzed after a systematic description of the whole system. HCPs thermal performances are compared among different coatings. The results show that the system has good heating and cooling functions, which can supply domestic hot water, space heating and space cooling loads. With two sorts of coating materials, which are acrylic resin coating, sprayed on HCPs, the daily average heat-collecting efficiency are respectively about 32％ and 20％ with the maximum points of 50％ and 30％, while at night the cooling capacity are about 20W/m2 and 40W/m2 in Tianjin, China in November.
