Washing method of air conditioner

Abstract

The invention discloses a washing method of an air conditioner. The washing method comprises the steps: S1, dewing is conducted, specifically, refrigeration is conducted to form condensate water for primary washing; S2, frosting is conducted, specifically, refrigeration is conducted to form a frost layer; S3, heating is conducted, specifically, heating is conducted to defrost to washing the surface of a heat exchanger, and sterilization is conducted; and S4, ventilating is conducted, so that the heat exchanger is quickly dried and cooled. The air conditioner comprises a control device, and operations of the rotating speed of a fan and the operating frequency of a compressor of the steps are preset in the control device, wherein the preset operation in the step S3 is that the mapping relation between the pipe temperature T of the heat exchanger and the frequency of the compressor and the mapping relation between the environment temperature and the rotating speed of the fan cooperate tocontrol the pipe temperature of the heat exchanger. According to the washing method, on the one hand, two-step cleaning is achieved, and sterilization is conducted; on the other hand, a system of theair conditioner is utilized to the largest extent; and secondly, through setting of the heating stage, the problems that under the high-temperature working condition, the operating frequency is too high, the air speed is too low, the pipe temperature rises too quickly, when frequency decreasing is triggered, the pressure is too high, and compressor driving protection occurs are avoided.

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 cl
