Abstract

The invention provides a PVT heat pump system capable of achieving day and night time-division heat, power and cold supply through solar radiation and sky cold radiation, and a photovoltaic power generation technology and a PVT heat pump technology which are relatively independent and mutually promoted in function are used simultaneously. Solar radiation energy and sky long-wave cold radiation energy are used as main energy resources of the system, and the energy is converted into electric energy, heat energy and cooling capacity through a PVT photoelectric-evaporation / condensation assembly in different modes at different times. The system integrates the various functions of power generation, heating, cooling and the like, equipment composition is simple, the equipment utilization rate is high, the energy saving effect is remarkable, the energy utilization rate is increased to the greatest extent, and the effects of achieving multiple purposes through the system and achieving day and night time-division heat, power and cold supply are achieved.

Description

Technical field [0001] The invention relates to a PVT heat pump system that utilizes solar photovoltaic power generation technology and PVT heat pump technology, absorbs solar radiation and sky cold radiation, and realizes day and night time-sharing thermoelectric cold supply. Background technique [0002] Solar energy is an inexhaustible new type of renewable energy. In the face of increasingly depleted fossil fuel resources and serious environmental pollution, solar and other renewable energy sources are effective substitutes for fossil fuels. Solar thermal utilization and photovoltaic utilization technologies are relatively mature and have been widely used in the fields of energy and power, refrigeration and air conditioning, social life, aerospace technology, etc. However, due to the low energy density, strong periodicity, and Poor stability and other shortcomings, there are also many problems in the use of solar energy. The low utilization rate of solar energy resources and ...
