[0033] Based on this problem, an embodiment of the present invention provides a multi-connection control method. see figure 1 , the multi-connection control method includes, for example:

[0034] Step S1: According to the running frequency of the multi-connector 200, determine the startup sequence of the type a configuration module 220;

[0035] Step S2: Determine the number n of configuration modules 220 to be run according to the capacity b of the internal machine and the capacity of the external machine;

[0036] Step S3: Run the configuration modules 220 sequentially according to the startup sequence and the number n of configuration modules 220 to be run.

[0037] It should be noted that when the multi-connector 200 runs at any operating frequency, the configuration modules 220 of type a of the multi-connector 200 have a corresponding startup sequence, so that the configuration modules 220 with high operating efficiency at the operating frequency are preferentially acti...

Abstract

The invention provides a control method and device for a multi-split air conditioner and the multi-split air conditioner. The control method for the multi-split air conditioner comprises the steps that: the starting sequence of a configuration modules is determined according to the operation frequency of the multi-split air conditioner; the number n of the configuration modules needing to be operated is determined according to the capacity b of the started indoor unit and the capacity b of the started outdoor unit; and the configuration modules are operated in sequence according to the starting sequence and the number n of the configuration modules needing to be operated. According to the control method and device provided by the embodiment of the invention, the problem of low operation efficiency caused by the fact that the multi-split air conditioner cannot control the configuration modules to operate according to the startup load demand is solved.

Description

technical field [0001] The present invention relates to the technical field of air conditioning control, in particular to a multi-connection control method, a multi-connection control device and a multi-connection connection. Background technique [0002] In a multi-module multi-connected system, there is an area with the best energy efficiency in the operation of each module. If the same module operation order or operation quantity is used for different load requirements when multi-lines are started, the optimal operation efficiency cannot be achieved, resulting in energy waste. Contents of the invention [0003] The problem solved by the present invention is: the multi-connector cannot control the operation of the configuration module according to the start-up load demand, resulting in the problem of low operating efficiency. [0004] In order to solve the above problems, on the one hand, the present invention provides a multi-line control method, including: according t...
