Embodiment Construction

[0030] The present invention will be described in detail below with reference to the drawings and examples.

[0031] image 3 It is a schematic diagram of the connection between the auxiliary heat exchanger and the outdoor heat exchanger in the outdoor unit of the air conditioner of the present invention; Figure 4 is a schematic diagram of the auxiliary heat exchanger in the outdoor unit of the air conditioner of the present invention; Figure 5 It is a schematic diagram of another angle of the auxiliary heat exchanger in the outdoor unit of the air conditioner of the present invention; Figure 6 It is a plan view of the auxiliary heat exchanger in the outdoor unit of the air conditioner of the present invention.

[0032] Such as Figure 3 to Figure 6 As shown, when the air conditioner is in heating operation, the compressor pressurizes the refrigerant to increase the temperature of the refrigerant, and the high-temperature and high-pressure refrigerant discharged from the...

Abstract

The invention relates to an outdoor unit of an air conditioner. The outdoor unit comprises an outdoor heat exchanger, an outdoor fan, a compressor and an electric heater, wherein an auxiliary heat exchanger which surrounds the compressor is arranged near the compressor; the auxiliary heat exchanger comprises a plurality of fins and a refrigerant pipe for serially connecting the fins; and the auxiliary heat exchanger is connected with the outdoor heat exchanger through the refrigerant pipe. Heat dissipated from the compressor is absorbed by the auxiliary heat exchanger, and the temperature of the outdoor heat exchanger can be increased by refrigerant circulation, therefore, the whole temperature of the outdoor heat exchanger is higher than the ice point, the frosting possibility of the outdoor heat exchanger can be effectively reduced, the capacity of the electric heater is reduced, and thus the electric energy is saved. In addition, the times for frosting when the air conditioner is powered off during heating can be reduced by increasing the temperature of the outdoor heat exchanger by utilizing the auxiliary heat exchanger, and the heating efficiency of the air conditioner is improved.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to an outdoor unit of an air conditioner in which an auxiliary heat exchanger is arranged around a compressor, and the refrigerant in the outdoor heat exchanger is heated by the heat of the compressor, thereby improving the defrosting effect. Background technique [0002] Generally speaking, an air conditioner is a refrigeration cycle that performs a sequential cycle of evaporation→compression→condensation→expansion in summer, and switches the four-way valve in winter to perform a heat pump heating cycle that is reverse to the refrigeration cycle to maintain the indoor temperature at the user's desired temperature. Cooling or heating systems on the required level. Air conditioners usually have both cooling and heating functions, the air purification function of inhaling indoor polluted air, filtering it and changing it into clean air and then discharging it indoors,...
