Embodiment Construction

[0035] Such as figure 1 As shown, the present invention provides an air conditioner outdoor unit, which includes:

[0036] heat exchanger 1;

[0037] The infrared heater 2 can radiate infrared waves to heat the heat exchanger 1, so as to heat and defrost the heat exchanger 1 when it is frosted;

[0038] The infrared reflective material 3 is arranged inside the outdoor unit of the air conditioner and can reflect infrared rays.

[0039] In the present invention, by setting an infrared heater inside the outdoor unit of the air conditioner, the heat exchanger can be heated by infrared radiation, and the infrared heater is radiated wave heating, which has a high utilization rate of the heat source and is not affected by the thermal resistance of the air. The effect of heating and defrosting is better, and with the infrared reflective material installed inside the outdoor unit of the air conditioner, it can reflect infrared rays, further enhancing the intensity and area of ​​infra...

Abstract

The invention provides an air-conditioner outdoor unit and an air-conditioner. The air-conditioner outdoor unit comprises a heat exchanger (1), an infrared heater (2) and an infrared reflection substance, wherein the infrared heater (2) can radiate infrared waves to heat the heat exchanger (1) so as to heat and defrost the heat exchanger (1) when the heat exchanger (1) frosts, and the infrared reflection substance is arranged in the air-conditioner outdoor unit, and can carry out the reflection effect on the infrared rays. By means of the air-conditioner outdoor unit, the heat source utilization rate is high, the influence of air heat resistance is avoided, the infrared rays can be reflected to the surface of the heat exchanger again, the area, radiated by the infrared rays, of the heat exchanger is increased, the utilization rate of the infrared rays is increased, the heat exchanger heating effect is improved, and the problem of defrosting existing in the low-temperature heating process of an existing outdoor unit heat exchanger is effectively solved.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to an air conditioner outdoor unit and an air conditioner. Background technique [0002] At present, when the outdoor unit of the air conditioner is heating at low temperature, the fins of the heat exchanger are cold surfaces. When the humidity in the air is high, the surface of the fins can easily reach the dew point, and then condensation will occur. The water will slowly condense into frost. When the frost layer completely covers all fin surfaces, the heat exchanger will lose its heat exchange performance, and the heat exchanger needs to be defrosted. [0003] Existing defrosting technologies mostly use reverse cycle, hot gas bypass, heat storage and defrosting, etc. These methods use the heat of the air conditioner itself to defrost. Changed to refrigeration, the heat exchanger of the outdoor unit uses the work of the compressor to heat the refrigerant to d...
