[0108] refer to Figure 5 , the present invention provides a third embodiment of a control method of one dragging multiple air conditioners, which is based on all the above-mentioned embodiments, and the control method of one dragging multiple air conditioners further includes:
[0109] Step S40, when the indoor unit is turned on, obtain the preset opening degree of the electronic expansion valve in the unopened indoor unit;
[0110] Step S50, while controlling the electronic expansion valve in the indoor unit to be opened to the initial opening degree, simultaneously controlling the electronic expansion valve in the unopened indoor unit to adjust to the preset opening degree.
[0111] In a one-to-many air conditioner, based on the fact that one or more indoor units can be turned on as needed, when adjusting the indoor unit to be turned on, the electronic expansion valve in the unturned indoor unit is opened to a fixed opening to prevent damage to the unstarted indoor unit , ...

[0114] refer to Image 6 , the present invention provides a fourth embodiment of a control method of one dragging multiple air conditioners, which is based on all the above-mentioned embodiments, and the control method of one dragging multiple air conditioners further includes:
[0115] Step S60, when the indoor unit to be turned on is turned on, the operation mode of the indoor unit to be turned on is acquired;
[0116] When the operation mode of the indoor unit to be turned on is the heating mode, the step of obtaining the outdoor ambient temperature value and the nominal capacity value of the indoor unit is performed.
[0117] According to the present invention, the one-to-multiple air conditioner operates in the heating mode. Based on the unstable change of the heating mode, when the indoor unit to be turned on is turned on, the operating mode of the indoor unit to be turned on is determined first. The specific operating mode can be determined according to the start comman...

Abstract
The invention discloses a method for controlling a multi-split air conditioner. The method comprises the following steps that when an indoor unit is started, an outdoor environment temperature value and the nominal capacity value of the indoor unit to be started are acquired; the initial opening degree of an electronic expansion valve in the indoor unit to be started are determined according to the outdoor environment temperature value and the nominal capacity value; and the electronic expansion valve in the indoor unit to be started is controlled to be opened to the initial opening degree. The invention further discloses a device for controlling the multi-split air conditioner and a computer readable storage medium. The initial opening degree of the electronic expansion valve in the indoor unit to be started is determined according to the outdoor environment temperature value and the nominal capacity value, the electronic expansion valve of the indoor unit to be started is controlledto be opened to the initial opening degree, and thus the initial opening degree of the electronic expansion valve of the indoor unit is adjusted according to outdoor environment changes. Therefore, the heating capacity of the multi-split air conditioner is optimized, the heating effect of the multi-split air conditioner is improved, and heating energy output is improved.
Description
technical field [0001] The invention relates to the technical field of air conditioners, in particular to a control method, device and computer-readable storage medium for one-driver-multiple air conditioners. Background technique [0002] One-to-many air conditioners are air conditioners in which one outdoor unit is connected to multiple indoor units. It is mainly applicable to homes. One outdoor unit is connected to the indoor units in each room, reducing the layout and installation of outdoor units. One-to-many air conditioners include heat pump-type one-to-many air conditioners and refrigeration-type one-to-many air conditioners. At present, when the heat pump type is running for heating, when the indoor unit is turned on, the opening of the electronic expansion valve is a fixed initial opening when the outdoor environment is not used. The requirements for the initial opening are different. Based on the existing system, the initial opening of the electronic expansion va...
