Abstract

The invention provides a multi-split air conditioner control method and device and an air conditioner. The method comprises the steps of detecting the air return temperature of an indoor unit; when the air return temperature is larger than or equal to a preset halt threshold value, controlling the indoor unit to enter the standby mode; by adopting the first time as an interval, circularly startingan internal fan. In this way, the internal fan is operated one time at the interval of the first time for performing air circulation, thermal aggregation inside the indoor unit is lowered, and therefore the influence of thermal aggregation on temperature monitoring is lowered, the disturbance caused by thermal aggregation inside the indoor unit on detected values is avoided, and the misjudgment possibility is eliminated.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to a multi-connected air conditioner control method, device and air conditioner. Background technique [0002] When the multi-connected air conditioner unit is in heating operation, some of the internal units are often running, and some of the internal units are shut down or shut down when the temperature reaches the temperature. [0003] Because the expansion valve of the indoor unit when the heating is shut down or the indoor unit is turned off at temperature needs to maintain a certain opening degree, so as to adjust the refrigerant operation demand of the whole system. Therefore, when the refrigerant circulates in the shutdown / warm shutdown internal unit, it will also dissipate heat to the outside. At this time, the fans of these indoor units are all in a stopped state, so the heat dissipated will be gathered inside the unit (especially some ceiling indoor unit...
