AI Technical Summary
In an air treatment system, when the outdoor unit has a large capacity and is connected to at least two indoor units, the amount of refrigerant is too high during low load operation, resulting in poor heating performance of the indoor unit, and frequent adjustment of the refrigerant regulating valve opening of the outdoor unit will increase noise.
When the indoor unit is in heating operation, if the capacity of the opened indoor unit is not greater than the first threshold value and the opening of the first regulating valve reaches the maximum set value, the opening of the first regulating valve is reduced and the opening of the second regulating valve is increased to ensure the heating performance of the indoor unit and reduce the noise of the outdoor unit.
By adjusting the opening of the regulating valve, the heating performance of the indoor unit is improved, and the noise of the outdoor unit is reduced, thereby improving the user experience.
