[0071] refer to figure 2 , the first embodiment of the control method for one-to-many air conditioners provided by the present invention, the control method of one-to-many air conditioners includes:

[0072] Step S10, when it is detected that defrosting or oil return is finished, increase the opening degree of the electronic expansion valve in the unopened internal unit, so as to remove the condensation on the heat exchanger of the unopened internal unit;

[0073] In the present invention, when the one-to-many air conditioner is running for heating, the system needs to run the defrosting or oil return mode to improve the performance of the air conditioner. However, when the system is running the defrosting or oil return mode, the internal unit is in the cooling mode , In this way, low-temperature refrigerant flows through the unopened internal machine. In order to prevent the condensation generated by the heat exchanger of the unopened internal machine from affecting the indo...

Abstract

The invention discloses a control method of a multi-split air conditioner. The control method of the multi-split air conditioner comprises the following steps of (1) increasing the opening degree of an electronic expansion valve in an indoor unit not turned on so as to remove condensation on a heat exchanger of the indoor unit not turned on when detecting completion of defrosting or oil return; and (2) restoring the electronic expansion valve of the indoor unit not turned on to the initial opening degree after completion of condensation removing. The invention further discloses the multi-splitair conditioner and a storage medium. According to the technical scheme, after completion of defrosting or oil return, the amount of refrigerant going into the heat exchanger of the indoor unit not turned on is increased in the heating process so as to remove condensation on the heat exchanger of the indoor unit not turned on by increasing the opening degree of the electronic expansion valve in the indoor unit not turned on; accordingly, the outer surface of the heat exchanger of the indoor unit not turned on for a long term is kept dry without concentration in real time.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a one-drive-multi-air conditioner, a control method thereof, and a storage medium. Background technique [0002] With the development of science and technology, people's living standards are also constantly improving, and air conditioners have generally entered the family, especially one-to-many air conditioners are more and more popular. One-to-many air conditioners have multiple indoor units and one outdoor unit, and multiple indoor units share one outdoor unit, so that the indoor unit can be used in multiple rooms, which is convenient and saves the installation of multiple outdoor units. For the one-drag air conditioner, sometimes the indoor unit in the room does not need to be turned on when no one is using the room, so the one-drag air conditioner is often not fully turned on, and the one-drag multi-air conditioner is not fully turned on when the indoor unit is not ...
