Problems solved by technology

[0002] At present, when the multi-connected system is heated to the point where defrosting is required, in order to avoid blowing cold air into the room and reduce the impact on user comfort, the existing technical solution is to increase the external heat source, one is to increase the electric auxiliary heat, but it will increase Additional equipment and energy consumption; the other is to add phase-change energy storage materials to release heat during defrosting, but this will not only add additional equipment, but also absorb part of the heat originally supplied to the room during energy storage, reducing the normal heating effect

Embodiment 1

[0054] Controlling at least a part of the indoor units in the standby state to operate in the cooling mode is specifically: controlling the indoor units in the standby state and meeting the operating conditions to operate in the cooling mode.

[0055] In the defrosting mode, it is necessary to judge whether the indoor unit meets the operating conditions, not all the indoor units in the standby state operate in the cooling mode, only when the operating conditions are met, they will operate in the cooling mode to prevent indoor heat exchange The heat absorbed by the device or the sudden operation of the indoor fan will adversely affect the indoor unit or the users in the room where the indoor unit is located. For example: the indoor unit in the standby state has certain restrictions, and the cooling mode cannot be turned on at will; or the room where the indoor unit in the standby state is located has certain restrictions on the environment, and the cooling mode cannot be turned ...

Embodiment 2

[0063] The difference from Embodiment 1 is that the operating conditions include: the environment where the indoor unit in the standby state is located satisfies the set working conditions.

[0064] The environment of the indoor unit is set with working conditions. When the environment of the indoor unit in the standby state meets the set working conditions, the indoor heat exchanger and indoor fan of the indoor unit can work. The environment of the room where the machine is located may adversely affect the users in the room. The environment where the indoor unit is located meets the set working conditions, including but not limited to, if there is no one in the room where the indoor unit is located, or there are people but the position of the person is not at the air outlet of the indoor fan, or the room where the indoor unit is located The temperature in the room is lower than the temperature of the cold air blown by the indoor fan, etc., so as to ensure that the cold air bl...

Embodiment 3

[0071] The difference from the first embodiment is that the contents of the second embodiment are combined on the basis of the first embodiment.

[0072] Specifically, the operating conditions include: the indoor unit in the standby state meets the set operating conditions, and the environment in which the indoor unit in the standby state is located meets the set working conditions (such as: the environment where the indoor unit is located is greater than the set duration threshold, and the temperature of the environment where the indoor unit is located is less than the set temperature threshold).

[0073] That is: when the multi-connected system is in the defrosting mode, after the indoor unit receives the defrosting request of the outdoor unit, the fan of the indoor unit running the heating mode and setting the anti-cold air function will stop; The sensing sensor judges whether there are people in the room and continues to reach the set time, and judges whether the room temp...

Abstract

The invention provides a control method, a control device, a multi-split air conditioner system and a readable storage medium. The control method is suitable for the multi-split air conditioner systemand includes the steps that the multi-split air conditioner system is controlled to enter a defrosting mode; and in the defrosting mode, at least part of indoor units in the standby state are controlled to run in a refrigerating mode. By means of the technical scheme, the defrosting process of outdoor units is accelerated, the defrosting time is shortened, the indoor unit shutdown waiting time during normal heating is shortened, in addition, an external heat source does not need to be increased for conducting heating and defrosting on the outdoor units, the heating effect cannot be affected,energy consumption is also reduced, the production cost of an enterprise is saved, and the use cost of a user is saved.

Description

technical field [0001] The present invention relates to the technical field of household control, in particular, to a control method, a control device, a multi-connection system and a computer-readable storage medium. Background technique [0002] At present, when the multi-connected system is heated to the point where defrosting is required, in order to avoid blowing cold air into the room and reduce the impact on user comfort, the existing technical solution is to increase the external heat source, one is to increase the electric auxiliary heat, but it will increase Additional equipment and energy consumption; the other is to add phase-change energy storage materials to release heat during defrosting, but this will not only add additional equipment, but also absorb part of the heat originally supplied to the room during energy storage, reducing the Normal heating effect. Contents of the invention [0003] In order to solve at least one of the above technical problems, a...
