[0029] Please refer to figure 2 , figure 2 A multi-line self-cleaning method provided by an embodiment of the present invention is shown. The multi-line self-cleaning method is applied to figure 1 The multi-connected air conditioning system 1 shown. Such as figure 2 As shown, the multi-line self-cleaning method includes:

[0030] Step S101, according to the preset frequency of the compressor, control the indoor unit 3 to enter the cooling mode, and control the fan of the indoor unit 3 to stop running.

[0031] In the embodiment of the present invention, when the multi-connected air-conditioning system 1 receives the automatic cleaning and cooling triggered by the user, the multi-connected air-conditioning system 1 is controlled to enter the cooling mode, and the compressor of the outdoor unit 2 is started to run at the preset compressor frequency. The fan of the indoor unit 3 stops running, so as to avoid the influence of the fan on the frosting and the bad experience ...

[0054] Please refer to Figure 4 , Figure 4 Another part of the schematic diagram of the multi-connected air-conditioning system 1 provided by the embodiment of the present invention is shown. The multi-split air conditioning system 1 further includes a first temperature sensor 4 , a second temperature sensor 5 and a third temperature sensor 6 .

[0055] The above-mentioned first temperature sensor 4 can be respectively arranged on the coil inlet of the evaporator of the indoor unit 3 of each air conditioner, and is used to collect the temperature of each indoor unit 3 evaporating into the coil. The above-mentioned second temperature sensor 5 can be respectively arranged on the coil outlet of the evaporator of the indoor unit 3 of each air conditioner, and is used to collect the temperature of the evaporating coil of the indoor unit 3 of each air conditioner. The third temperature sensor 6 is respectively arranged on the coil of the evaporator of the indoor unit 3 of each a...

Abstract

The embodiment of the invention provides a multiple on-line self-cleaning method and a multi-split air conditioning system. The multiple on-line self-cleaning method is applied to the multi-split airconditioning system, and the multi-split air conditioning system comprises a plurality of indoor units. The multiple on-line self-cleaning method includes the steps that the indoor units are controlled to start a cooling mode according to a preset compressor frequency, and fans of the indoor units are controlled to stop running; average evaporation temperature information corresponding to the indoor units in the cooling mode is acquired according to a preset time period; the compressor frequency is adjusted according to the average evaporation temperature information, so that the indoor unitsall satisfy a preset refrigeration exit condition; and the indoor units are controlled to start a heating mode to complete cleaning. According to the scheme, the compressor frequency is adjusted according to the average evaporation temperature information of the indoor units which still operate in the cooling mode, it is ensured that each indoor unit can reach the ideal frosting effect, and the final cleaning effect of each indoor unit is ensured.

Description

technical field [0001] The invention relates to the field of multi-connection technology, in particular to a multi-connection self-cleaning method and a multi-connection air conditioning system. Background technique [0002] The multi-connection system is commonly known as "one-to-many", and in recent years, the multi-connection system has become more and more popular with users for its energy saving and low operating costs. Take the multi-split air conditioner system as an example, one outdoor unit is connected to two or more indoor units by piping. It saves the additional cost of multiple outdoor units, but due to its one-to-many feature, the control process is not flexible enough, and some functions are not effective. Among them, it has a great influence on the self-cleaning function of the air conditioner. [0003] Due to the long-term use of the air conditioner, it is inevitable that the heat exchanger of the indoor unit of the air conditioner will accumulate dust. A...
