Embodiment Construction

[0032] Such as Figure 1-2 As shown, the present invention provides an air conditioner outdoor unit, which includes:

[0033] Compressor 1, outdoor heat exchanger 5 and chassis 6;

[0034] The radiator 8 is arranged on the chassis 6 and can communicate with the exhaust port of the compressor 1 through a refrigerant pipeline. The principle of deicing by using refrigerant heating is to add a heat dissipation plate on the chassis, which is arranged along the drainage holes on the chassis, and heats the ice through the radiator to melt it so that it can be completely discharged.

[0035] Through the radiator arranged on the chassis, and the refrigerant pipeline can be connected with the exhaust port of the compressor, the high-temperature and high-pressure refrigerant discharged from the compressor exhaust port can be effectively introduced into the radiator to The heat exchange is completed in the radiator, so that the residual ice formed by defrosting on the chassis can be hea...

Abstract

The invention provides an outdoor unit of an air conditioner, the air conditioner and a control method of the outdoor unit of the air conditioner. The outdoor unit of the air conditioner comprises a compressor (1), an outdoor heat exchanger (5) and a chassis (6); and a radiator (8) is arranged on the chassis (6), and can communicate with an exhaust port of the compressor (1) through a refrigerantpipeline. A high-temperature and high-pressure refrigerant discharged by the exhaust port of the compressor can be effectively leaded into the radiator to achieve the heat exchange effect in the radiator, so that residual ice formed by defrosting on the chassis can be heated to water for removal, the condition of generating the residual ice on the chassis is effectively prevented, the residual iceis thoroughly removed, and the heat exchange effect of the heat exchanger is improved.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to an air conditioner outdoor unit, an air conditioner and a control method for the air conditioner outdoor unit. Background technique [0002] For multi-connected outdoor units, especially those working in low-temperature and high-humidity environments (such as -7°C / -8°C), during long-term heating operation, multiple defrosting and defrosting may occur. , a large amount of defrosting water will be precipitated from the outdoor heat exchanger. Under normal circumstances, the defrosting water will be completely discharged through the water guide groove and the drain hole, and there will not be much water on the chassis; [0003] If the water does not completely flow away from the chassis of the air conditioner, when the unit starts heating after defrosting, the surface temperature of the evaporator is very low, and because the outdoor ambient temperature is very ...
