Embodiment 1

[0037] like figure 1 and figure 2 As shown, the present invention is equipped with a layer of ice-phobic coating on the fin-tube heat exchanger outside the air-conditioning room. The heat exchanger is composed of fins 1 and copper tubes 2. Ice coating, a layer of ice-phobic coating is prepared on the surface of the copper tube 2 . The ice-phobic coating has a composite microstructure of nano-protrusions and nano-pores, and the static contact angle of water droplets on the ice-phobic surface (coating) is ≥150°; the rolling angle of water droplets on the ice-phobic surface (coating) is ≤5°; The preparation method of the ice-phobic surface (coating) can adopt anodic oxidation method, coating method, chemical corrosion candle method, plasma treatment method, thermal oxidation method, sandblasting treatment method, one-step solution immersion method or sol-gel method; The prepared sample finally needs to be modified by the low surface energy substance FAS, and the ice-phobic sur...

Embodiment 2

[0039] The difference between this embodiment 2 and embodiment 1 is only that, as image 3 As shown, the heat exchanger is a parallel flow heat exchanger, including flat tubes 4 , collecting pipes and cooling fins, and the outer surfaces of the flat tubes 4 , collecting pipes and cooling fins are all provided with an ice-phobic layer 3 .

[0040] The present invention also provides an air conditioner, including an outdoor unit for the air conditioner. By setting the air conditioner with an ice-phobic layer, when the air conditioner is in defrosting operation, the frost can be quickly detached from the surface of the heat exchanger, which has the characteristics of short defrosting time and high efficiency.

[0041] Based on the above technical scheme, the present invention has at least the following beneficial effects:

[0042] The ice-phobic layer provided on the exposed surface of the outdoor heat exchanger for air-conditioning provided by the present invention can not only...

Abstract

The invention provides an outdoor device for an air conditioner, and the air conditioner, and relates to the technical field of air conditioners. By adoption of the outdoor device for the air conditioner, and the air conditioner, the technical problem of poor heat exchange performance, caused by frosting, of outdoor heat exchangers is solved. The outdoor device for the air conditioner comprises adevice body and an anti-frosting protection layer arranged on the whole or one part of the device body. The device body is an outdoor heat exchanger of the air conditioner. The anti-frosting protection layer is a deicing layer. By arranging the deicing layer on one part of or the whole exposed surface of the outdoor heat exchanger, the appearance of ice crystals can be delayed, the problem of frosting of the surface of the heat exchanger is effectively solved, and the frosting degree of the outdoor heat exchanger is greatly reduced or the frosting start time of the outdoor heat exchanger is greatly delayed. When the air conditioner operates in a defrosting mode, frost can be rapidly removed from the surface of the heat exchanger; the defrosting time is short, and the efficiency is high; and when removed from the surface of the heat exchanger, condensate water or frost can take away tiny particles such as dust on the surface of the heat exchanger, and thus, a good self-cleaning functionis achieved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an outdoor device for air conditioners and an air conditioner with the same. Background technique [0002] The air conditioners currently on the market are usually in heating operation, because the surface temperature of the outdoor heat exchanger is lower than the dew point temperature of the outdoor air, the water vapor in the air will condense into water droplets on the surface of the condenser. When the air temperature or the surface temperature of the condenser is lower than 0°C, the condensed water droplets will quickly form frost (fine ice crystals) on the surface of the condenser. When the frost layer becomes thicker and thicker, the ventilation resistance will increase. affect heat transfer performance. [0003] To solve this problem, the usual way is to change the direction through the four-way valve of the air conditioner to heat the condenser and melt the ic...
