Method and device for collecting condensed water to clean air conditioner based on rotation speed regulation of compressor

Abstract

A method and a device for collecting a condensed water to clean an air conditioner based on rotation speed regulation of a compressor are disclosed. A heat exchanger in the air conditioner is used for condensing water vapor inside the air conditioner into a liquid water, and thereby cleaning the dirt adhered on the surface of the heat exchanger. The step of condensing the water vapor into the liquid water comprises: determining a surface temperature for condensation of the heat exchanger as an expected temperature, on the basis of a current environment temperature and a current environment humidity of the air conditioner; regulating and maintaining the temperature of the heat exchanger at the expected temperature by regulating the rotation speed of the compressor in the air conditioner. An optimal temperature of the heat exchanger in the current environment is determined by analyzing the influence of the environment temperature and the environment humidity to the dew point, thereby acquiring enough condensed water for cleaning the dirt on the surface of the heat exchanger. When the actual temperature of the heat exchanger is unequal to the expected temperature, the rotation speed of the compressor is regulated to rise up or lower down the temperature of the heat exchanger, accordingly maintaining the temperature of the heat exchanger at the determined optimal temperature, and thereby achieving the automatic cleaning and self-adaptive regulation of the heat exchanger, and ensuring the cleaning effect of the heat exchanger.

Description

technical field

[0001] The invention relates to the technical field of air-conditioning equipment, in particular to a method and a device for collecting condensed water and cleaning an air-conditioner based on the rotation speed of a compressor. Background technique

[0002] During the operation of the air conditioner, the surface of the heat exchanger will accumulate dirt. On the one hand, these dirt will reduce the heat transfer performance of the heat exchanger, and on the other hand, it is easy to breed bacteria and form spot mold. Odor.

[0003] At present, the above problems can be solved in two ways. The first way is to add a dust removal device, such as using a nozzle to spray pressure gas on the surface of the heat exchanger to remove dust and dirt, but this way is costly, bulky, and It is difficult to set up and is not suitable for air conditioners; the second method is to use the condensed water formed when the heat exchanger is used as an evaporator to take away...
