Abstract
A control method for a multi-split air conditioning system capable of simultaneous cooling and heating to solve the problem that uneven cooling and heating occurs when running an existing multi-split air conditioning system. The method includes calculating the cooling or heating temperature effect deviation of each indoor unit on the basis of the indoor ambient temperature and set temperature of the environment where each indoor unit is located; calculating the total cooling effect deviation and total heating effect deviation of an multi-split air conditioning system on the basis of the horsepower of all the indoor units and the corresponding cooling temperature deviation or heating temperature deviation; and selectively adjusting the degrees of opening of valve boxes on the basis of the total cooling effect deviation and the total heating effect deviation. The method ensures balanced distribution of refrigerant, balanced running effects the units, and avoids uneven heating and cooling.
