Problems solved by technology

Since the indoor unit of the central air conditioner is generally installed in the ceiling, for the user, the installation position is high and difficult to clean, and some dust and impurities will accumulate on the surface of the heat exchanger of the indoor unit heat exchanger. If it is not cleaned in time, it will affect the heat exchanger. The heat exchange efficiency is low, and it is easy to breed bacteria, which will cause the air conditioner to produce peculiar smell, affect the air quality of the indoor environment, and even affect the health of users.

no. 1 example

[0048] see figure 1 , this embodiment provides a multi-split unit 1, the multi-split unit 1 includes a controller 2 and a plurality of indoor units 4, the number of indoor units 4 is greater than 1, and 3 to 5 indoor units 4 can be set. Each indoor unit 4 is equipped with a wind speed sensor 3, and the wind speed sensor 3 is used to monitor in real time the wind speed value F1 of the air inlet side and the wind speed value F2 of the wind outlet side of each indoor unit 4; The wind speed value F1 of the air inlet side and the wind speed value F2 of the air outlet side of 4 are used to determine whether the indoor unit 4 starts self-cleaning.

[0049] see figure 2 , based on the above multi-line 1, this embodiment also provides a multi-line self-cleaning control method, including the following steps:

[0050] S11: Real-time monitoring of the wind speed value F1 of the air inlet side and the wind speed value F2 of the air outlet side of each indoor unit 4 .

[0051]Among them...

no. 2 example

[0066] see image 3 , based on the multi-line 1 of the first embodiment, this embodiment also provides a multi-line self-cleaning control method, which differs from the control method in the first embodiment in that the control method in this embodiment pre- The number N of indoor units 4 that start self-cleaning is set, specifically including the following steps:

[0067] S21: Real-time monitoring of the wind speed value F1 of the air inlet side and the wind speed value F2 of the air outlet side of each indoor unit 4 .

[0068] S22: Preset the number N of indoor units 4 that start self-cleaning.

[0069] In this way, in order to ensure cleaning efficiency and avoid triggering low-pressure protection, the number N of indoor units 4 that start self-cleaning is preset, and according to the wind speed value F1 of the air inlet side and the wind speed value F2 of the air outlet side of each indoor unit 4, Synchronously start N indoor units 4 for self-cleaning.

Abstract

The invention provides a multi-split air conditioner and a self-cleaning control method thereof, and relates to the technical field of air conditioner assembly. The self-cleaning control method of themulti-split air conditioner comprises the steps that the air inlet side air speed value F1 and the air outlet side air speed value F2 of each indoor unit are monitored in real time; and whether eachindoor unit starts self-cleaning or not is judged according to the corresponding air inlet side air speed value F1 and the air outlet side air speed value. Self-cleaning can be conducted, dust and impurities accumulated on the surface of the multi-split air conditioner are removed in time, the heat exchange efficiency of the heat exchanger is guaranteed, bacterium breeding and peculiar smell generation are avoided, and the air quality of the indoor environment and user health are guaranteed. Meanwhile, the situation that only one indoor unit can be started for self-cleaning is avoided, the multiple indoor units can be flexibly controlled for self-cleaning according to the actual situation, the self-cleaning efficiency is improved, meanwhile, the situation that only all the indoor units canbe started together for self-cleaning is avoided, and triggering of low-voltage protection is avoided.

Description

technical field [0001] The invention relates to the technical field of air conditioner assembly, in particular, to a multi-connector and a self-cleaning control method thereof. Background technique [0002] At present, with the maturity of central air-conditioning technology, central air-conditioning has gradually entered the homes of ordinary people from the original use of shopping malls and hospitals. [0003] Since the central air conditioner only needs one outdoor unit to match multiple indoor units, the central air conditioner is also called multi-connected, which greatly saves the storage space of the outdoor unit; It is more beautiful and can save indoor space at the same time. Household central air-conditioning has become the first choice for many new properties and young people. [0004] As people's requirements for health and air quality are getting higher and higher, air conditioners, as ordinary household appliances, not only need to achieve the effect of cool...
