PVT heat pump system capable of realizing divided daytime and night-time heat, power and cooling supply by means of solar radiation and sky cold radiation

摘要

A PVT heat pump system capable of realizing divided daytime and night-time heat, power and cooling supply by means of solar radiation and sky cold radiation. Photovoltaic power generation technology and PVT heat pump technology are used, and the two are relatively independent and mutually promoted in terms of function. The main energy sources of the system are solar radiation energy and sky long-wave cold radiation energy, and energy is converted into electric energy, heat energy and cooling capacity by means of PVT photoelectric-evaporation/condensation components in different working modes in different time periods. The system has multiple functions integrated into same, such as power generation, heating and cooling, and the composition is simple, the device utilization rate is high, the energy saving effect is significant, the energy utilization rate is improved to the greatest extent, and the multiple purposes and divided daytime and night-time combined heat, power and cooling supply are thus achieved.
