Abstract

The embodiment of the invention provides a self-cleaning control method and device and a multi-split air conditioner, and relates to the technical field of air conditioners. The self-cleaning controlmethod comprises the steps: obtaining a reference current value of an indoor fan of the indoor unit; acquiring a real-time current value of the indoor fan; judging whether the indoor unit corresponding to the indoor fan meets a self-cleaning condition or not according to the real-time current value and the reference current value; and if the indoor unit meets the self-cleaning condition, controlling the multi-split air conditioner to conduct self-cleaning. According to the self-cleaning control method and device and the multi-split air conditioner, whether the indoor unit needs to be self-cleaned or not can be effectively and accurately judged, and the steps are simple and easy to implement.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a self-cleaning control method, a multi-line self-cleaning control device and a multi-line. Background technique [0002] Multi-connection means that one outdoor unit matches multiple indoor units. Some dust and impurities will accumulate on the surface of the heat exchanger coil of the indoor unit. If it is not cleaned in time, it will not only affect the heat exchange efficiency of the heat exchanger, but also easily breed bacteria, causing the The device produces peculiar smell, affects the air quality of the indoor environment, and even affects the health of users. [0003] When multiple indoor units need to perform self-cleaning, if the self-cleaning is started at the same time, it is easy to cause the protection of the unit due to the low pressure of the outdoor side, which will stop the self-cleaning action and even affect the normal use of the multiple units. C...
