The invention relates to a multi-energy multi-source complementary heating system and an operation method thereof, wherein the system comprises five cycles: the first cycle is an air source heat pump cycle heating and heat storage system and consists of a first evaporator and a first condenser; the second cycle is an intermediate heat exchange and heat storage system which consists of a first condenser, a heat storage and heat exchange water tank and a second evaporator; the third circulation is a water source heat pump heat exchange system which consists of a second evaporator and a second condenser; the fourth cycle is a user side heat utilization system and consists of a second condenser and a heat dissipation tail end; the fifth cycle is a solar heat exchange and storage system, which consists of a solar heat collection plate and a heat storage and exchange water tank. The heating system can exert the complementary advantages of all subsystems to the maximum extent, fully utilizes clean energy such as solar energy, air energy and the like, and solves the problems of low solar energy utilization rate, poor reliability, low heat supply stability of an air source heat pump, low energy efficiency and the like. |
