Washing method for air conditioner

Abstract

The invention discloses a washing method for an air conditioner. The washing method comprises the following steps of: (S1) moisture condensation, namely forming condensate water on the surface of a heat exchanger by refrigeration of the air conditioner so as to wash the surface of the heat exchanger; (S2) frost formation, namely forming a frost layer on the surface of the heat exchanger by refrigeration of the air conditioner; (S3) heating, namely heating by using the air conditioner to realize defrosting so as to wash the surface of the heat exchanger, and sterilizing; and (S4) ventilation, namely making an indoor unit run in a ventilation mode so as to quick dry and cool the heat exchanger. The air conditioner comprises a control device, andoperations of the rotating speed of a fan and the running frequency of a compressor in the steps are preset in the control device. On one hand, the washing method for the air conditioner disclosed by the invention realizes two-step washing, also realizes sterilization, can be used for effectively cleaning the heat exchanger and maintains the heat exchanger to be sanitary and free of pollution; and on the other hand, the rotating speed of the fan and the running frequency of the compressor are set in each stage of the washing method so that the system of the air conditioner is utilized as far as possible, and thus the cleaning effect of theair conditioner is improved.

Description

technical field [0001] The invention belongs to the field of air conditioners, and specifically proposes an air conditioner cleaning method. Background technique [0002] There is a lot of dust and dirt in the air conditioner room after the air conditioner in daily use is placed or used for a long time. These dusts are attached to the heat exchanger, and the air conditioner will produce condensed water during the cooling process, and the condensed water will stay on the heat exchanger of the air conditioner. The dust on the heat exchanger is in a humid environment, which will easily cause the evaporator to breed Lots of bacteria. In this way, the accumulation of dirt and bacteria will not only reduce the heat exchange efficiency of the evaporator, but will also be discharged into the environment with the use of the air conditioner, thereby polluting the environment and possibly producing peculiar smells, thereby damaging the cleanliness and comfort of the environment, and a...

Problems solved by technology

However, the present invention only controls the frequency limit of the compressor in the heating and defrosting stage, and there is no limit in other stages, resulting in a waste of resources

[0004] The existing technology relies on frosting and defrosting or condensed water in the cleaning process. This cleaning method can effectively clean the dust and other dirt on the surface of the air conditioner, but the cleaning method is closer to the surface of the heat exchanger tube The cleaning effect of the more stubborn dust and other dirt is poor

In addition, the self-cleaning mode of the air conditioner is based on the air conditioner operation theory of cooling and heating, but it relies too much on the mode limitation of the normal operation of the air conditioner, and fails to make full use of the cooling and heating system of the air conditioner according to the characteristics of each stage of self-cleaning characteristics, resulting in high energy consumption
