Example Embodiment

[0029]In the following, the present invention will be further described in conjunction with the embodiments.

[0030]A self-cleaning control method for an air-conditioning system is suitable for the following air-conditioning systems. An air detection device can be installed at the air inlet of the air-conditioning system to detect TSP, PM10, PM2.5 or PM1 and other particulate matter indicators in the air. The control device can choose products such as Tianjia series air quality detectors, and can work when the air conditioning unit is turned on or off.

[0031]The self-cleaning control method of the air conditioning system of the present invention includes the following steps:

[0032]1) The indoor unit is self-cleaning;

[0033]1.1) The air detection device detects the air quality of the indoor return air;

[0034]1.2) When any value of TSP, PM10, PM2.5 or PM1 in the indoor air is higher than the standard value, or sulfur dioxide is higher than the standard value, go to step 1.3); otherwise, go ...

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...
