Embodiment 1

[0036] Since the cleanliness of the outdoor heat exchanger has no effect on the indoor air quality, the cleaning of the outdoor heat exchanger is often easily overlooked. The thermal performance directly affects the cooling and heating capacity of the air conditioner, and the outdoor environment where the outdoor heat exchanger is located is harsher and more likely to accumulate dust. Over time, it is easy to affect the heat transfer performance of the outdoor heat exchanger. Therefore, it is very necessary to propose The invention discloses a self-cleaning method for an outdoor heat exchanger, so as to realize the automatic cleaning of the outdoor heat exchanger. Due to the different functions and working conditions of the outdoor heat exchanger and the indoor heat exchanger, the self-cleaning control method of the indoor heat exchanger cannot be applied to the self-cleaning of the outdoor heat exchanger, and the cleaning of the outdoor heat exchanger is affected by the outdoo...

Embodiment 2

[0064] This embodiment proposes an air conditioner, which is a fixed-frequency air conditioner, including the self-cleaning control method for the outdoor heat exchanger of the fixed-frequency air conditioner described in Embodiment 1. For details, please refer to Embodiment 1 and the appended figure 1 , figure 2 recorded, and will not be repeated here.

[0065] Compared with the prior art, the advantages and positive effects of the present invention are: the self-cleaning control method of the outdoor heat exchanger of the fixed-frequency air conditioner of the present invention can make the outdoor heat exchanger quickly form a large amount of low-density frost in a short time, The frost is then quickly melted to wash away the dust adhering to the outdoor heat exchanger.

Abstract

The invention discloses a self-cleaning control method for a fixed frequency air-conditioning outdoor heat exchanger and an air conditioner. The control method comprises the following steps: (1)detecting the current air-conditioning operation mode, (2) to control frost formation of outdoor heat exchangers, (3) according to the current operation mode of air-conditioning, corresponding control methods are adopted to melt the frosting of outdoor heat exchangers and complete the self-cleaning control. The self-cleaning control method of the constant frequency air-conditioning outdoor heat exchanger enables the outdoor heat exchanger to quickly bind a large amount of low density frost in a short time, and then quickly melt the frost, thereby washing away the dust attached to the outdoor heat exchanger.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a self-cleaning control method for an outdoor heat exchanger of a fixed-frequency air conditioner and an air conditioner. Background technique [0002] Whether the air conditioner is running or standing still, dust will adhere to the indoor and outdoor heat exchangers. For the consideration of indoor air quality and heat exchange efficiency of indoor heat exchangers, many brands of air-conditioning products have applied the self-cleaning control method of indoor heat exchangers for the cleaning of indoor heat exchangers. The outdoor heat exchanger is located outdoors, there is no air quality problem caused by the operation of the air conditioner, and its cleanliness is easily overlooked by people. However, due to the external environment, the outdoor heat exchanger is more likely to adhere to more and thicker dust. The heat transfer performance of the air conditioner ha...
