The invention discloses a refrigerator condenser heat radiating
system which comprises a water pump, a water tank, a controller, a condenser temperature sensor, a water tank temperature sensor and a
liquid level sensor, wherein the condenser temperature sensor, the water tank temperature sensor and the
liquid level sensor are connected with the controller; the condenser temperature sensor is arranged on the condenser, the water tank temperature sensor is arranged on the water tank, and the
liquid level sensor is arranged on the top of the water tank; and the condenser is a connecting
pipe which is connected with a
cooling pipe and a condenser
pipe side by side, one end of the
cooling pipe is directly connected with the water tank, the other end of the
cooling pipe is connected with the water tank through the water pump, and a water outlet valve is arranged at the lower part of the water tank. The invention also discloses a control method of the refrigerator condenser heat radiating
system, the control method comprises the following steps: automatically cooling the condenser by use of the
temperature difference of the water tank cooling water and the condenser; and simultaneously heating the water in the cooling
pipe by use of the heat of the condenser, thereby not only cooling the condenser but also recycling the heat of the condenser. The control method provided by the invention has the advantages of
high energy utilization rate, and environmental friendliness and
energy conservation; and by utilizing the device and control method provided by the invention, a refrigeratorcan achieve a function of supplying hot water.
