Heating system of solar energy heat pump in type of accumulating heat by soil as well as method for supplying heat

Abstract

This invention discloses a solar energy heat pump heating system of earth heat storage solar energy accumulator, heat exchanger, heat pump device and circulating pump in which outlet of solar accumulator connects to the inlet of heat exchanger, which outlet connects with the inlet of solar energy accumulator via heat pump and circulation pump so as to form heat-carrying fluid loop, side inlet or outlet of the heat pump connects with users, heat exchanger is set under the earth as the heat retainer suitable for winter use.

Description

technical field [0001] The invention relates to a heat supply system and a heat supply method using energy, more specifically, to a heat supply system and a heat supply method using solar energy. Background technique [0002] Heat pump is a recognized efficient and energy-saving heating and air conditioning method. However, when it is used for heating in winter in northern regions, the air source has the disadvantages of large outdoor heat exchangers, frequent defrosting, and low coefficient of performance. With the destruction of groundwater resources and other issues, soil sources have disadvantages such as high initial investment. [0003] Solar energy is an abundant, clean, and safe energy source. Since the 1970s, in view of the limited supply of conventional energy sources and the increasing pressure on environmental protection, many countries in the world have set off an upsurge in the development and utilization of solar energy. However...

AI Technical Summary

Problems solved by technology

However, water heat storage or phase change heat storage is usually used, which makes the heat storage tank bulky and expensive

Moreover, in winter or when solar energy is insufficient, the solar collector cannot heat up the heat-carrying fluid, and the system cannot supply heat.
