Air conditioner outdoor unit with electric heating device and control method of air conditioner outdoor unit

Abstract

The invention relates to an air conditioner outdoor unit with an electric heating device. The air conditioner outdoor unit comprises a front panel, an annular air guiding ring and a heater arranged on the surface of the outer side of the air guiding ring. The air guiding ring is arranged on the front panel in the air outlet direction of a fan. The heater is connected with a power supply control device through a power wire. The heater is a soft belt body with the two ends connected through a locking device. The invention further provides a control system of the air conditioner outdoor unit with the electric heating device and a control method of the air conditioner outdoor unit with the electric heating device. The soft heater is arranged on the air guiding ring of the air conditioner outdoor unit, when an outdoor low-temperature air conditioner defrosts, the generator is electrified to work, the temperature of the air guiding ring can be effectively increased through the heat of the heater, steam produced during defrosting can be prevented from being frozen into ice on the air guiding ring, and the purpose of protecting safety running of the axial fan of the air conditioner is achieved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an outdoor unit of an air conditioner with an electric heating device and a control method thereof. Background technique [0002] The outdoor unit of the existing air conditioner generally uses an axial flow fan. When the axial flow fan is working, it rotates at a high speed in the air guide ring of the front panel of the outdoor unit to discharge air forward. Opportunity to blow out cold air that is lower than the ambient temperature, which will cause the temperature of the air guide ring to drop below the ambient temperature. When the air conditioner enters defrosting, the axial flow fan will stop running, and the temperature of the condenser will decrease during defrosting. When the frost on the condenser is finally melted, water vapor will be generated inside the outdoor unit. When the water vapor diffuses to the wind guide ring, it will condense on it. When the air ...

[0002] The outdoor unit of the existing air conditioner generally uses an axial flow fan. When the axial flow fan is working, it rotates at a high speed in the air guide ring of the front panel of the outdoor unit to discharge air forward. Opportunity to blow out cold air that is lower than the ambient temperature, which will cause the temperature of the air guide ring to drop below the ambient temperature. When the air conditioner enters defrosting, the axial flow fan will stop running, and the temperature of the condenser will decrease during defrosting. When the frost on the condenser is finally melted, water vapor will be generated inside the outdoor unit. When the water vapor diffuses to the wind guide ring, it will condense on it. When the air conditioner resumes heating operation, it will blow out cold air again. This will cause the condensed water on the air guide ring to freeze, and the ice layer will continue to thicken during long-term operation. In severe cases, it will touch the axial flow fan blades, affecting the safe operation of the fan and causing the air conditioner to malfunction.
