Abstract
A multi-split air conditioning system having an outdoor unit and multiple indoor units and control method therefor. The control method comprises the following steps: obtaining an outdoor ambient temperature when an indoor unit sends a start instruction received from a user; determining whether the outdoor ambient temperature falls within a preset temperature range; and determining an operation mode of the multi-split system according to operations status of other existing started indoor units when the outdoor ambient temperature falls within the preset temperature range.
Claims12
A method for controlling a multi-split air conditioning system having an outdoor unit and multiple indoor units, comprising:
- acquiring an outdoor ambient temperature using the outdoor unit when one of the indoor units sends a starting instruction received from a user;
- determining whether the outdoor ambient temperature is within a preset temperature range;
- and
- determining an operating mode of the multi-split air conditioning system according to current operating conditions of the indoor units, when the outdoor ambient temperature is within the preset temperature range.
A multi-split air conditioning system, comprising at least one outdoor unit and at least two indoor units, wherein the at least two indoor units and the at least one outdoor unit form a refrigerant cycle loop and communicate with each other, the outdoor unit comprises a controller configured to receive a control signal from the indoor units and control the outdoor unit according to the control signal;
- the controller is configured to:
- acquire an outdoor ambient temperature when one of the indoor units sends a starting instruction received from a user;
- determine whether the outdoor ambient temperature is within a preset temperature range;
- and
- determining an operating mode of the multi-split air conditioning system according to current operating conditions of the indoor units, when the outdoor ambient temperature is within the preset temperature range.
