When the system has the faults of water flow fault, high-pressure fault, large temperature difference fault, high-temperature fault and the like caused by the water channel blockage problem, the water flow is reduced, the water flow sensor transmits signals to the controller 13, and when the water flow is smaller than the set flow value of the controller 13, the controller 13 automatically adjusts the opening of the bypass valve 12, so that the working flow of the air source heat pump heating system is met, the water channel blockage problem is caused in the use process in winter, the system is not stopped, and the anti-freezing problem of winter equipment is solved.
