Zero-energy-consumption uninterrupted operation solar heating system

Abstract

The invention belongs to the technical field of heating equipment, and particularly relates to a zero-energy-consumption uninterrupted operation solar heating system. The zero-energy-consumption uninterrupted operation solar heating system comprises a heat pump system, a solar photovoltaic system and a heat storage system which are connected with one another, wherein the heat pump system is used for supplying heat by utilizing the heat of the solar photovoltaic system or the heat storage system; the solar photovoltaic system is used for converting solar energy into electric energy so as to heat the heat storage system and converting the solar energy into heat energy so as to supply heat to the heat pump system; and the heat storage system is used for converting the electric energy of the solar photovoltaic system into heat to supply heat to the heat pump system. According to the zero-energy-consumption uninterrupted operation solar heating system provided by the embodiment of the invention, indoor heating can be achieved by arranging the heat pump system, heat can be provided for the heat pump system by arranging the solar photovoltaic system, and heat can be stored by arranging the heat storage system so as to supply heat to the heat pump system.

Description

technical field [0001] The invention belongs to the technical field of heating equipment, in particular to a solar heating system with zero energy consumption and uninterrupted operation. Background technique [0002] At present, it is difficult for solar heat pumps to achieve uninterrupted heating throughout the day, especially in areas with large temperature differences between day and night, where the nighttime temperature is low, and there is frost on the outdoor unit of the heat pump, which seriously affects the efficiency and normal operation of the heat pump. [0003] In order to solve the frosting problem of the solar heat pump outdoor unit, there are currently two main methods: one method is to increase the chassis electric heating of the outdoor unit, but this method must consume high-quality energy, and the power consumption will increase significantly; the second method is to use The heat storage tank and the outdoor heat exchanger adopt a shell-and-tube heat exc...
