效率介于5%~11%之间。
Abstract
In order to improve the utilization efficiency of solar energy by traditional collector-heat storage walls in cold regions, this study takes a village house in Xinjiang Shihezi region as the research object, builds a set of photovoltaic collector-heat storage wall system, and tests the thermoelectric performance of the photovoltaic collector-heat storage wall system in the village house in cold regions under the winter climate. The results show that compared with the traditional collector-heat storage wall, the heat collection effect of the PV collector-heat storage wall system is obviously better than that of the traditional one, the average heat gain of the room of the PV collector-heat storage wall system is 51.41 W/m2, and that of the room of the traditional collector-heat storage wall is 47.32 W/m2, and the average heat gain of the room of the PV collector-heat storage wall system is 4.09 W/m2 higher than that of the traditional collector-heat storage wall, which is the same as that of the traditional collector-heat storage wall. 4.09 W/m2; the electric efficiency of the PV collector-heat storage wall system fluctuates between 6% and 11%, the energy efficiency fluctuates between 7% and 26%, and the exergy efficiency fluctuates between 5% and 11%. The results of the experimental research in this paper have certain guiding significance for the application of photovoltaic collector-thermal storage wall system in the severe cold region.
