Problems solved by technology

Since the volumes of the two rooms and the parameters of the air conditioners in the two rooms are different, in the process of controlling the air conditioners in the two rooms using the traditional control method, the two rooms are independently heated or cooled, which will cause the difference between the two rooms. The heat flow between the two rooms is not uniform, which in turn leads to poor stability in the heating process or cooling process of the two rooms, and finally leads to poor stability when the indoor temperature of the two rooms reaches the set temperature
It can be seen that in the case of simultaneously heating or cooling two rooms with heat exchange, the existing control method cannot take into account the temperature adjustment rate and the stability when the temperature of the two rooms reaches the set temperature

Abstract

The invention relates to the technical field of intelligent air conditioners, and discloses a method for controlling an air conditioner. The method comprises the steps that under the condition that a first room and a second room with heat exchange are heated or cooled at the same time, a first temperature difference value between a set temperature and a first indoor temperature and a second temperature difference value between the set temperature and a second indoor temperature are obtained; under the condition that the first temperature difference value is larger than a first temperature threshold value, a first air conditioner of the first room is controlled according to a first control strategy, and a second air conditioner of the second room is controlled according to a second control strategy; and under the condition that the first temperature difference value is smaller than or equal to the first temperature threshold value, a first air conditioner of the first room and a second air conditioner of the second room are controlled according to a third control strategy. By the adoption of the method, the stability of the indoor temperature in the heating or cooling process can be improved, and then the stability of the indoor temperatures of the two rooms reaching the set temperature is improved. The invention further discloses a device for controlling the air conditioner and the multi-split air conditioner.

Description

technical field [0001] The present application relates to the technical field of intelligent air conditioners, for example, to a method and device for controlling an air conditioner, and a multi-connected air conditioner. Background technique [0002] At present, air conditioners can be installed in different rooms in a family. These air conditioners can be multi-connected air conditioners or split-type air conditioners. Each air conditioner can adjust the temperature of the room where it is located. In the process of adjusting the temperature in the home, a set temperature can be set, and the room whose indoor temperature is higher than the set temperature is determined as a cooling room. If the air conditioner in the cooling room is in the heating mode, the air conditioner in the cooling room will The operating mode of the system is switched to cooling mode, so that the temperature of multiple rooms in the home can be adjusted to the target temperature. [0003] For the a...
