Air source heat pump assisted solar comprehensive heating and air-conditioning system

The invention discloses an air source heat pump assisted solar comprehensive heating and air-conditioning system. The system is suitable for heating in winter and air conditioning in summer in places with rich solar energy resources, such as villas, low-rise office buildings and rural housing. The system is characterized by consisting of a solar heat collecting system, a radiation heating system and an air source heat pump system. The source heat pump assisted solar comprehensive heating and air-conditioning system adopts the following key technology that one set of solar heat collecting system is adopted, can be used for directly carrying out radiation heating and also can assist the air source heat pump system in carrying out heating and air conditioning; and the system utilizes a radiation heat dissipation tail end and air conditioner composite set, can sufficiently utilize solar energy resources, enables heat collecting efficiency of a solar heat collector to be improved and solves the problems of high energy consumption and low efficiency of a conventional heating system.
