Abstract

The invention discloses a solar energy and heat pump combined heat supply system suitable for alpine regions and a method thereof. The system involves a solar heat collector, a heat pump compressor, acondensation heat accumulator, an auxiliary condenser, a heat regenerator, a throttle valve, an evaporator, a heat supply tail end, circulating water pumps, three-way valves and the like. According to the system, a solar heat collection technology, an air source heat pump technology and a phase-change heat storage technology are organically combined to solve the problem of heat supply in the alpine regions. According to winter environment change characteristics in the alpine regions, a solar energy independent heat supply mode, a solar energy and heat pump combined heat supply mode, a heat pump independent heat supply mode and a condensation heat accumulator heat supply mode can be correspondingly adopted by the system to carry out continuous uninterrupted heat supply on buildings. According to the system and the method, solar energy and air energy can be comprehensively utilized for carrying out stable heat supply on the buildings, and the method and the system are efficient and energy-saving, and are especially suitable for the alpine regions with strict atmospheric environment.

Description

technical field [0001] The invention relates to the technical field of solar energy and heat pump heat supply, in particular to a combined solar energy and heat pump heat supply system and method suitable for alpine regions. Background technique [0002] The demand for heating in winter in alpine regions is prominent, but conventional energy sources are scarce and oil and gas transportation is difficult. Therefore, combining the energy and climate characteristics of the alpine region, the development of efficient and clean heating technology has far-reaching significance for the reduction of carbon emissions and the sustainable development of buildings in the alpine region of our country. my country's alpine regions are rich in solar energy resources, and its utilization and development prospects are very broad. However, solar energy is discontinuous, unstable, and greatly affected by the environment and climate, which restricts its wide application. Air source heat pump i...
