Embodiment 1

[0029] According to an embodiment of the present invention, an embodiment of a control method of a multi-line working mode is provided. It should be noted that the steps shown in the flow charts of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions , and, although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0030] figure 1 It is a flow chart of an optional control method for multiple online working modes according to an embodiment of the present invention, such as figure 1 As shown, the method includes the following steps:

[0031] Step S102, generating a mode switching signal if the multi-connected internal unit performs working mode switching;

[0032] Step S104, based on the mode switching signal, the working modes of other multi-connected indoor units and multi-connected outdoor units are sw...

Embodiment 2

[0067] According to another aspect of the embodiment of the present invention, there is also provided a control device 30 in a multi-line working mode, such as image 3 with Figure 4 As shown, the control device 30 includes:

[0068] A generating unit 301, configured to generate a mode switching signal if the multi-connected internal unit performs working mode switching;

[0069] The switching unit 302 is configured to switch the working modes of other multi-connected internal machines and multi-connected external machines in conjunction with each other based on the mode switching signal.

[0070] Optionally, the internal unit that performs working mode conversion in the multi-connection can be any one of all the internal units in the multi-connection, and the other internal units in the multi-connection are relative to the same multi-connection. When the mode is switched, except for the internal unit that performs the working mode conversion, all other internal machines sh...

Abstract

The invention discloses a multiple on-line working mode control method, device and system. The method comprises the following steps: if multiple on-line internal machines perform working mode conversion, generating a mode conversion signal; and converting the working mode of other multiple on-line internal machines and multiple on-line external machines on the basis of the mode conversion signal. The method solves the technical problem of lower efficiency in the air conditioner multiple on-line conversion working mode, and implements the technical effects of simplifying operation and eliminating mode confliction in the multiple on-line working mode conversion process.

Description

technical field [0001] The present invention relates to the field of air conditioner control, in particular to a control method, device and system for multi-connected working modes. Background technique [0002] In the field of multi-connected air conditioners, the system can only choose to operate in cooling or heating mode at the same time, and the mode switching of the whole machine is realized by switching the internal unit mode. When the number of internal units is large, the following two methods are usually used to switch the mode of the whole unit: [0003] 1. First open priority mode, that is, the whole machine mode runs according to the first opened internal machine mode, and if other internal machine modes are inconsistent with the first opened internal machine mode, it will report a mode conflict and interrupt the operation. Therefore, the mode switching of the whole machine needs to switch the modes of all the internal machines under the system, that is, it is ...
