摘要
本文在对目前国内外光伏光热建筑一体化(BIPV/T)系统、地源热泵-光伏光热(PV/T)耦合系统的研究现状和发展方向进行综述及分析的基础上,针对当前建筑外围护结构中光伏可利用面积较大却未被完全利用及阴雨天光伏余热供应不足的问题,提出了一种将地源热泵技术与BIPV/T系统相结合的耦合系统,即地源热泵-BIPV/T耦合系统。首先分析了该耦合系统的运行模式,然后以该耦合系统中单位面积的南向BIPV/T墙体为例,对其外表面温度和得热量进行了模拟,并与普通墙体进行了对比,结果显示:夏季时,地源热泵-BIPV/T耦合系统中BIPV/T墙体1天的得热量可比普通墙体1天的得热量减少0.027 kWh/m^(2);冬季时,该BIPV/T墙体1天的得热量可比普通墙体1天的得热量增加0.097 kWh/m^(2);以上数据说明地源热泵-BIPV/T耦合系统具有较好的节能效果。
On the basis of summarizing and analyzing the research status and development direction of PV photothermal building integration(BIPV/T)system and ground source heat pump-PV photothermal(PV/T)coupling system at home and abroad,aiming at the problems of large usable area of PV in the building envelope but not fully utilized and insufficient supply of PV waste heat in cloudy and rainy days.A system combining ground source heat pump technology with BIPV/T system is proposed,that is,ground source heat pump-BIPV/T coupling system.Firstly,the operation mode of the coupling system is analyzed,and then the external surface temperature and heat gain of the south facing BIPV/T wall per unit area in the coupling system are simulated,and then compared with ordinary wall,the results show that the heat gain of the BIPV/T wall of the ground source heat pump-BIPV/T coupling system in one day can be reduced by 0.027 kWh/m^(2) compared with that of the ordinary wall in one day in summer,and in winter,the one day heat gain of the BIPV/T wall can be increased by 0.097 kWh/m^(2) compared with that of the ordinary wall.The above data shows that ground source heat pump-BIPV/T coupling system has better energy saving effect.
