Solar energy coupling air source heat pump integrated air conditioning system and heating and refrigerating method thereof

The invention discloses a solar energy coupling air source heat pump integrated air conditioning system and a heating and refrigerating method thereof. A solar evaporation heat collector is arranged on the inner surface of a shell of an outdoor unit of a solar energy air source heat pump, an indoor unit of the air source heat pump is arranged in a heating room, and a capillary copper pipe mesh radiation heating layer of the air source heat pump is arranged on a base layer of a heating floor and regulated and controlled through a control system and circulation pipelines of the control system to achieve solar energy coupling air source heat pump integrated heating and refrigerating. According to the solar energy coupling air source heat pump integrated air conditioning system and the heating and refrigerating method thereof, thermal field coupling is performed on solar energy and the air source heat pump, functional advantage complementation optimization of the solar energy and the air source heat pump is achieved by controlling the coupling system, the initial investment and operation cost of the system is further lowered, and the function guarantee performance and using comfortableness of the system are improved.
