Kind Code:
A1
Abstract:
A control method for a three-pipe multi-split air conditioning unit, comprising: determining an operating mode of an outdoor unit of an air conditioning unit; when the outdoor unit operates in a refrigeration main body mode, determining whether a heating effect of an indoor heating unit is poor, and if it is determined that the heating effect of the indoor heating unit is poor, enabling the air conditioning unit to enter a refrigerant quantity compensation mode of the indoor heating unit to increase the refrigerant quantity flowing into the indoor heating unit; and when the outdoor unit operates in a heating main body mode, determining whether a refrigeration effect of an indoor refrigerant unit is poor, and if it is determined that the refrigeration effect of the indoor refrigerant unit is poor, enabling the air conditioning unit to enter a refrigerant quantity compensation mode of the indoor refrigerant unit to increase the refrigerant quantity flowing into the indoor refrigerant unit. By means of the configuration above, an indoor unit can have a good refrigerant effect or heating effect, regardless of whether the outdoor unit operates in the refrigeration main body mode or operates in the heating main body mode, such that the user experience is improved.
