Solar air collector heating system and method

Abstract

The invention relates to a solar air-heating system and method. The system comprises a heat pipe and a vacuum glass pipe, a glass pipe with a vacuum sandwich is adopted by the vacuum glass pipe, the vacuum glass pipe is arranged outdoors, an evaporation section of the heat pipe is arranged in a cavity of the vacuum glass pipe, a condensation section of the heat pipe is arranged indoors, solar heat is directly or indirectly absorbed by the evaporation section of the heat pipe, and then heat exchange with indoor air is performed by the condensation section through a radiator. By adopting the system and the method, the efficiency of absorption of solar energy and the efficiency of heat transfer can be improved greatly, constant heating can be realized indoors, and an indoor environment can be made comfortable. Moreover, the system has the advantages of good safety and reliability and low cost.

Description

technical field [0001] The invention relates to a heating technology, in particular to a high-efficiency and low-cost system and method for using solar energy to heat indoors. Background technique [0002] At present, high-efficiency solar heating is generally an active heating technology, which requires the following processes to realize: 1) The light-to-heat conversion process of solar energy generally uses high-efficiency selective heat-absorbing coatings or heat-absorbing films with low reflectivity; Absorption and storage generally require thermal media and heat storage containers, and high-efficiency heat insulation from the outside world is required; 3) The transportation of thermal energy to the room generally requires circulating pumps and heat exchangers to achieve heat transfer through thermal media; 4) Thermal energy is in the Indoor diffusion generally realizes the heating function through natural convection or fan forced heat exchange. [0003] However, high-e...
