Multi-connection control method, multi-connection and computer storage medium

Abstract

The invention discloses a multi-connection control method. The multi-connection control method includes the following steps: when the oil return opening condition is satisfied, acquiring the first indoor unit in the multi-connection that is not in the windless mode; The target opening of the first electronic expansion valve of the indoor unit; the first electronic expansion valve is adjusted to the target opening for oil return, wherein the target opening is greater than the first preset opening corresponding to the windless mode. The present invention adjusts the indoor unit that is not in the windless sense to a larger opening degree when the multi-line needs to return the oil, so that the main oil return is carried out by the indoor unit that is not in the windless sense, so that even if the indoor unit without windy feeling is not in the indoor unit The opening of the machine is still small, and the oil return is less or no oil return, which can also ensure the overall oil return effect of the multi-connection. User comfort in the space where the wind-sensing indoor unit works.

Description

technical field [0001] The present invention relates to the technical field of multi-connection, in particular to a control method of multi-connection, multi-connection and computer storage medium. Background technique [0002] When the multi-connected indoor unit is in the no-wind-sensing mode, if the multi-connection has oil return demand, the opening of the indoor unit electronic expansion valve required for the no-wind-sensing mode is usually small, and the indoor unit electronic expansion valve required for oil return is open. The speed is usually large. Therefore, at present, it is first to exit the windless mode to control the oil return of each indoor unit of the multi-connection. User comfort when in oil. [0003] The above content is only used to assist the understanding of the technical solutions of the present invention, and does not mean that the above content is the prior art. SUMMARY OF THE INVENTION [0004] The main purpose of the present invention is to...

[0002] When the multi-connected indoor unit is in the windless mode, if the multi-connected unit has oil return demand, the electronic expansion valve opening degree of the indoor unit required by the windless mode is usually small, and the electronic expansion valve of the indoor unit required for oil return is opened. Therefore, at present, exit the no-wind sensing mode first to control the oil return of each indoor unit of the multi-connection unit, and then re-enter the no-wind-sensing mode after the oil return is completed, which will greatly reduce the return of the multi-connection unit. User comfort when oiling
