Solar energy auxiliary heat pump and phase-change energy-storage integrated heating system

Abstract

The invention relates to the field of new energy utilization, and discloses a solar energy auxiliary heat pump and phase-change energy-storage integrated heating system. The integrated heating systemcomprises a solar photoelectric photothermal collector, a hot water box, a first circulating pump, a heat pump, a heat exchanger and a phase-change energy-storage unit; solar auxiliary heat circulation is formed by the solar photoelectric photothermal collector through the first circulating pump, the heat pump is connected with one side of the heat exchanger, the solar photoelectric photothermal collector provides electric energy to the heat pump system for driving, and the phase-change energy-storage unit is connected with the other side of the heat exchanger; and a second water outlet is connected with a radiator through the other side of the heat exchanger and the phase-change energy-storage unit, and returns a backwater inlet. In the daytime, electricity amount consumed by the heat pump can be significantly reduced by adopting a solar photovoltaic photothermal technology and a large number of solar heat collection is used for heating, and the operating cost is significantly reduced; and at night, the phase-change energy-storage unit is used for heat storage, the utilization rate of trough electricity can be greatly improved, and thus waste of resources is greatly reduced.

Description

Technical field [0001] The invention relates to the field of new energy utilization, in particular to a solar auxiliary heat pump and a phase change energy storage integrated heating system. Background technique [0002] With the continuous development of industrial production, people's consumption of conventional energy continues to increase. The consumption of energy sources such as coal, oil and natural gas is on the rise. The ever-increasing demand has led to over-exploitation of various energy sources, which has a bad impact on the ecological environment. Today, energy conservation and emission reduction have become the trend of the times, saving energy and reducing carbon emissions are the most fashionable way of life. At present, all countries are committed to the development of new energy. Solar energy is an inexhaustible green energy. It is one of the most promising and cleanest energy sources in the 21st century. [0003] Because power plants continue to generate elect...
