Air-conditioning outdoor machine for preventing dust accumulation of condenser

Abstract

The invention discloses an air-conditioning outdoor machine for preventing dust accumulation of a condenser, which comprises a shell, a chassis, a compressor, the condenser, a fan motor, an outdoor fan, a baffle and a top cover. A high-voltage electrode generator is arranged between the shell at the rear part and the condenser. The air-conditioning outdoor machine is additionally provided with the high-voltage electrode generator, thus, under attraction of the high voltage, an electrode of the outdoor machine can realize dust adsorption to greatly reduce quantity of accumulated dust of fins of the condenser, improve the heat exchange efficiency of the condenser on the outdoor side, reduce resistance that the air passes through the fins of the condenser so as to reduce the rotating speed of the fan and reduce noise. The performance quality and the energy-saving rate after the product operates for a long time are improved. Meanwhile, after the air-conditioning outdoor machine shuts down, the high voltage disappears to make the dust adsorbed on the electrode drop down naturally so as to reduce assembly and disassembly times of the electrode.

Description

technical field [0001] The invention relates to an air conditioner, in particular to an air conditioner outdoor unit which prevents dust from accumulating in a condenser. Background technique [0002] Generally, an air conditioner is a device that causes a refrigerant inside to undergo a refrigeration cycle consisting of a compression process, a condensation process, an expansion process, and an evaporation process. In the air conditioner, the refrigerant that has been compressed into a high-temperature and high-pressure state can dissipate heat to the outside in the condenser, and when it flows through the expansion valve, its temperature and pressure are significantly reduced, and then the low-temperature, low-pressure refrigerant flows through the evaporator. Absorbs heat and finally flows back to the compressor. Among them, the compression process, condensation process and expansion process are carried out in the outdoor unit of the air conditioner, and the evaporation ...

Problems solved by technology

[0004] like image 3 As shown, the condenser 15 of the outdoor unit of the air conditioner in the prior art, due to its long-term operation outdoors, under the condition of forced convection, it is easy to cause too much dust to accumulate on the fins of the condenser, resulting in a decrease in heat exchange efficiency

Excessive dust accumulation will also increase the resistance of air passing through the condenser fins, resulting in increased fan speed and increased noise
