Embodiment Construction

[0027] The embodiments of the present invention are described in detail below. This embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation methods and specific operating procedures are provided, but the protection scope of the present invention is not limited to the following implementation example.

[0028] see figure 1 , this embodiment discloses a device for reducing frosting on the evaporator 6, which includes a compressor 1, a condenser 2, a dry filter 3, a capillary tube 4 and an evaporator 6 connected in sequence to form a refrigeration circuit, and the outlet end of the capillary tube 4 passes through Two parallel branch pipelines are connected to the inlet end of the evaporator 6, and the two parallel branch pipelines are respectively branch pipeline one and branch pipeline two. An auxiliary capillary 7 and a froster 8 are arranged in sequence along the refrigerant flow direction.

[0029] The froster...

Abstract

The invention discloses a device for reducing frosting of an evaporator, which comprises a compressor, a condenser, a dry filter, a capillary tube and an evaporator which are sequentially connected to form a refrigeration circuit, and the outlet end of the capillary tube is connected to the evaporator through two parallel branch pipelines. At the inlet end of the evaporator, the two side-by-side branch pipelines are respectively branch pipeline 1 and branch pipeline 2. A solenoid valve is installed on the branch pipeline 1, and auxiliary capillary tubes are arranged on the branch pipeline 2 along the direction of refrigerant flow. and froster. The invention also discloses a method for reducing the frosting of the evaporator. Compared with the prior art, the present invention has the following advantages: the water vapor in the air is condensed on the froster before the evaporator through the froster, reducing the amount of frosting on the evaporator, thereby slowing down the decay of the heat exchange efficiency of the evaporator, And prolong the defrosting cycle of the evaporator, improve the heat exchange effect of the refrigerator, and reduce the overall power consumption of the refrigerator.

Description

technical field [0001] The invention relates to the technical field of refrigerators, in particular to a device and method for reducing frosting of an evaporator. Background technique [0002] With the development of the times, the functions of refrigerators have been gradually improved. The emergence of air-cooled refrigerators has solved the shortcomings of direct-cooled refrigerators that cannot be automatically frosted. Wide attention of refrigerator manufacturers and scholars. The increase of the frost layer will affect the heat transfer efficiency of the evaporator, reduce the heat transfer capacity of the evaporator, and then affect the cooling effect of the entire refrigerator. The existing defrosting methods include contact defrosting heaters and thermal radiation defrosting heaters. The power of defrosting heaters is generally relatively high. Reducing the defrosting interval of the evaporator can improve the heat exchange effect of the evaporator, but at the same...
