Automatic cleaning system, air conditioner and control method

Abstract

The invention provides an automatic cleaning system, an air conditioner and a control method. The automatic cleaning system comprises a water storing device of which the first end is connected to an indoor unit condensed water collector and an outdoor unit condensed water collector, a cleaning water pump of which one end is connected to the second end of the water storing device and while the other end is connected to an indoor unit water sprayer and an outdoor unit water sprayer, a first detecting module for detecting the first operation state parameters of an indoor heat exchanger, a second detection module for detecting the second operation state parameters of an outdoor heat exchanger, and a control module for determining whether to start the cleaning water pump to automatically clean the indoor heat exchanger and / or the outdoor heat exchanger according to the first operation state parameters and / or the second state parameters. According to the technical scheme, the system has the advantages that the heat exchangers can be automatically cleaned, so that the timeliness and efficiency of cleaning of the heat exchangers can be effectively improved, and as a result, the operation reliability of the air conditioner can be improved; in addition, the condensed water can be recycled, and thus the water resource can be saved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an automatic cleaning system, an air conditioner and a control method. Background technique [0002] With the development of air-conditioning technology, air-conditioning is known and used by more and more people because of its energy-saving, high-efficiency and comfort features. During the long-term operation, the dust on the heat exchanger of the outdoor unit will gradually increase due to accumulation, which will increase the wind resistance and reduce the return air volume; and during the long-term operation of the air conditioner indoor unit, the dust on the return air filter will also increase. Because the accumulation gradually increases, the wind resistance increases, resulting in a decrease in the return air volume. Therefore, when the air conditioner is in cooling operation, the evaporation side air volume is reduced, so that the liquid refrigerant cannot be c...

Problems solved by technology

[0002] With the development of air-conditioning technology, air-conditioning is known and used by more and more people because of its energy-saving, high-efficiency and comfort features. During the long-term operation, the dust on the heat exchanger of the outdoor unit will gradually increase due to accumulation, which will increase the wind resistance and reduce the return air volume; and during the long-term operation of the air conditioner indoor unit, the dust on the return air filter will also increase. Because the accumulation gradually increases, the wind resistance increases, resulting in a decrease in the return air volume

Therefore, when the air conditioner is in cooling operation, the evaporation side air volume is reduced, so that the liquid refrigerant cannot be completely evaporated, and the unevaporated liquid refrigerant returns directly to the compressor, causing the compressor to have a hidden danger of liquid compression; while in the heating operation of the air conditioner , the air volume on the condensing side is reduced, which will make the cooling state of the refrigerant worse, resulting in excessively high superheat of the return air of the compressor and high discharge temperature, which will affect the life of the compressor

It can be seen that the degree of dust accumulation in the heat exchanger of the indoor unit and the heat exchanger of the outdoor unit directly affects the stability of the operation of the air conditioner. decreased reliability

In the existing air conditioners, the maintenance personnel often come to the door for maintenance after the air conditioner breaks down and shuts down, and most of the time they clean the heat exchanger artificially, which is not only inefficient, but also the timeliness of cleaning is not good enough.
