The utility model discloses a multi-
energy coupling heat pump heating and cooling
system which comprises a
solar heat collecting
system connected with a user side to form a heating loop, an air source
heat pump system connected with the user side to form a heating and cooling loop, and a
water source heat pump system connected with the user side to form a heating and cooling loop. The
solar heat collecting system, the air source heat pump system and the
water source heat pump system are arranged for multi-
energy coupling heat supply and cold supply; one part of
heat energy generated by the
solar heat collection system is transmitted to the user side, and the other part is stored in the seasonal heat storage water tank; part of
heat energy and cold energy generated by the air source heat pump system are transmitted to a user side, part of the
heat energy and the cold energy are stored in the seasonal heat storage water tank, and
energy consumption is reduced by arranging the seasonal heat storage water tank to store the heat energy and the cold energy; the input end of the
water source heat pump system is connected with a seasonal heat storage water tank, the
water source heat pump system transmits heat energy and cold energy in the seasonal heat storage water tank to a user side, the solar heat
collection system is communicated with the air source heat pump system through a first
defrosting pipeline, and the seasonal heat storage water tank is communicated with the air source heat pump system through a second
defrosting pipeline. By arranging the first
defrosting pipeline and the second defrosting pipeline, the problem that heat cannot be supplied when the air source heat pump frosts is solved; heating and cooling can be flexibly adjusted according to actual requirements of users by setting multiple working
modes, and a more comfortable
living environment is provided.
