Problems solved by technology

Due to the large difference between the return air temperature of the fresh fan and the return air temperature of the ordinary indoor unit, if the fresh fan and the ordinary indoor unit are installed in the same system, they will usually affect each other. The temperature should not be too high. On the one hand, the temperature of the air sent by the ordinary indoor unit should not be too high. If it is too high, the human body will not feel cool.

Abstract

The invention discloses a control method for a multi-split air conditioner system. The multi-split air conditioner system involves an outdoor unit and an indoor unit group composed of a plurality of indoor units, wherein each indoor unit is provided with an electronic expansion valve, and each indoor unit can be arbitrarily switched between the working mode of an ordinary unit and the working modea fresh air ventilator according to requirements. The control method comprises the following steps of A, detecting the running state of the multi-split air conditioner system, the running number of the indoor units powered-on and started, and the working mode corresponding to each indoor unit once at each rated time interval; and B, enabling the electronic expansion valves to adjust the opening correspondingly within a predetermined opening adjustment range by the indoor units powered-on and running according to the detection conditions in step A.

Description

Technical field [0001] The present invention relates to the technical field of multi-online systems, in particular to a control method for multi-online systems. Background technique [0002] The return air of the indoor unit of the general air conditioner is the wind in the indoor room. This kind of wind has been circulating indoors and is generally not fresh; a comfortable indoor environment usually requires a certain amount of fresh air entering the room through the outside, and usually requires new installation. The fan comes to get fresh air. [0003] The return air outlet of the new air-conditioning fan needs to be connected to the air outlet to introduce fresh air from the outdoor side to the indoor room. Usually, when the ambient temperature of the outdoor side is higher than that of the indoor room, (for example, the ambient temperature of the outdoor unit is 40°C and the indoor environment temperature is 27°C) , The return air temperature of the indoor unit of the fresh a...
