Abstract
The utility model discloses a heat pump with an anti-freezing function. The heat pump comprises a body, a circulating water pump, a heat exchanger, a water tank and a controller, wherein the heat exchanger is arranged in the body; the water tank is arranged outside the body; the controller is connected with the circulating water pump; a water outlet of the heat exchanger is connected to an inlet of the water tank; an outlet of the water tank is connected to an inlet of the circulating water pump; an outlet of the circulating water pump is connected to a water inlet of the heat exchanger; and a first temperature sensor is also arranged outside the body and is connected with the controller. When the heat pump stops to be in a non-work state, the external temperature can be detected through the first temperature sensor even though the external temperature is reduced to be below zero DEG C, and a signal is emitted by using the controller to control work of the circulating water pump, so that delivery of internal liquid in the heat exchanger is realized, the icing probability can be reduced, and the service life of the heat pump is prolonged.
