Air source heat pump coupling cross-seasonal buried pipe heat storage and supply system

The utility model relates to an air source heat pump coupling cross-seasonal buried pipe heat storage and supply system which comprises a secondary network water supply pipe, a secondary network water return pipe, an air source heat pump set and a heat storage device. The air source heat pump set comprises a water inlet and a water outlet, an inlet of the secondary net water return pipe and an outlet of the secondary net water supply pipe are both communicated with a user side, an outlet of the secondary net water return pipe is communicated with the water inlet, and an inlet of the secondary net water supply pipe is communicated with the water outlet; the heat storage device comprises a buried pipe and a compression type heat pump set, the buried pipe is buried underground, the buried pipe is communicated with a secondary network water supply pipe and a secondary network water return pipe to form circulation so as to store heat, and the compression type heat pump set is communicated with the buried pipe, the
