A solar greenhouse heat storage and supply rural residential system according to any one of claims 1 to 3, characterized in that the heat pump heating circulating water pipe is buried under the permafrost layer, and the surface of the heat pump heating circulating water pipe is provided with an insulating layer.
10. A method of solar greenhouse regenerative heating rural home system according to any of claims 1 to 9, comprising:
if the indoor temperature of the sunlight greenhouse reaches a first preset temperature, heating the working medium in the heat pump heating circulating water pipeline by using the heat in the sunlight greenhouse collected by the air source heat pump, and storing the heated working medium in an energy storage tank;
and if the temperature of the rural house is lower than the second preset temperature, the heat radiation device releases the heat provided by the working medium in the tail end heat supply circulating water pipeline to the rural house.
