Self-cleaning control method of air-conditioning system

Abstract

The invention relates to a self-cleaning control method of an air conditioning system. The self-cleaning control method is characterized in that an air quality detection device is arranged at an indoor air return port position of an air conditioner and is used for detecting particulate matters such as TSP, PM10, PM2.5 or PM1 in indoor air to judge whether self-cleaning needs to be carried out or not, so that the judgment timeliness and accuracy are effectively improved, and meanwhile, an indoor heat exchanger and an outdoor heat exchanger are cleaned in a frosting-defrosting mode, an outer door fan reversal mode and the like, so that the self-cleaning effect of the air conditioning system is greatly improved, and the market requirements are fully met.

Description

technical field [0001] The invention relates to an air-conditioning control method, in particular to a self-cleaning control method, in particular to a self-cleaning control method for an air-conditioning system. Background technique [0002] The self-cleaning of the air conditioning system may include indoor unit self-cleaning and outdoor unit self-cleaning. [0003] At present, the self-cleaning of indoor units mainly includes: ① Determine whether to make filter or evaporator cleaning reminders by regularly cleaning or calculating the accumulated running time. The disadvantage of this method is that due to the different specific use environments of indoor units, the cleaning The degree varies greatly, so it is prone to false reminders, and cannot accurately and objectively reflect the cleanliness of the air filter or evaporator. ②Enter self-cleaning by detecting the current of the indoor fan motor. After the indoor heat exchanger is dirty and blocked, the surface resista...

AI Technical Summary

Problems solved by technology

However, the defect of this method is that when detecting the degree of dust accumulation through the change of the fan current of the outdoor unit, ① the dust accumulation in the outdoor heat exchanger must be very serious, resulting in a significant change in the current, and the accuracy is low; ② there is a serious lag, when When entering self-cleaning, the outdoor heat exchanger has accumulated a lot of dust

[0005] To sum up, most of the current air-conditioning system self-cleaning methods have deficiencies such as judgment lag and low accuracy, which seriously affect the cleaning effect of the air-conditioning system. Therefore, it needs to be improved in order to better meet the needs of the market
