Refrigerator condenser heat radiating system and control method thereof

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of refrigerators for household appliances, in particular to a cooling system for a refrigerator condenser and a control method thereof. Background technique [0002] In the refrigeration process of the refrigerator, after the refrigerant is compressed and vaporized by the compressor, the condenser is required for heat dissipation and cooling, and then to the evaporator for heat exchange refrigeration. Hanging a condenser to dissipate heat or adding a fan to force it to dissipate heat. This method of natural heat dissipation is greatly affected by the ambient temperature. In summer, the ambient temperature around the refrigerator is high, resulting in poor cooling effect of the condenser and poor cooling of the refrigerator. The external heat dissipation of the device will affect the living environment of the user. Contents of the invention [0003] The problem to be solved by the present invention is to p...

Problems solved by technology

[0002] In the refrigeration process of the refrigerator, after the refrigerant is compressed and vaporized by the compressor, the condenser is required for heat dissipation and cooling, and then to the evaporator for heat exchange and refrigeration. If the condenser does not dissipate heat well, the cooling efficiency will be reduced. At present, the heat dissipation method of the condenser generally adopts side plate heat dissipation or back heat dissi
