Abstract

The invention is a solar energy heating device, including underground heat storage device filled with variable-phase substance, compressor, expansion valve, condenser and fan matching with the condenser, and also solar energy heat collector, where the heat storage device, expansion valve, solar energy heat collector and compressor are connected in turn through the first circulating pipeline, the heat storage device, compressor, condenser and expansion valve are connected in turn through the second circulating pipeline, and there are several valves installed on the two circulating pipelines. The invention makes full use of solar energy and terrestrial heat to store the heat as storing heat; as releasing heat, uses the heat storage device and the terrestrial heat to release the heat so as to provide the needed heat. It is especially suitable for the place with enough sunlight and large day-night temperature difference, and uses the variable phase principle to make high efficiency absorption on the solar energy and simultaneously uses the variable phase principle to largely absorb soil heat and finally achieves no-pollution low-consumption heating.

Description

technical field [0001] The invention relates to a heating device, in particular to a heating device using solar energy and geothermal heat. Background technique [0002] The applicant has proposed a number of patent applications for heating and / or cooling devices using geothermal or seawater as cold and heat sources and using easy-to-phase-change substances as heat exchange carriers, such as No. 00106206.9 "Liquid-liquid cold heat source Device", No. 00123494.3 "well type liquid cold and heat source system", No. 00123495.1 "geothermal liquid cold and heat source system". However, the disadvantage of their existence is that these devices do not fully utilize the energy of the sun, and are affected by geographical location in application, and are relatively regional. Especially for those places where the intensity of solar radiation is high and the temperature difference between day and night is large, such as the Tibet region of my country, how to make full use of the energy...
