Abstract

Disclosed herein is a simultaneous cooling and heating operation controlling method of a multi air conditioner system comprising a plurality of indoor units connected in parallel to an outdoor unit. The simultaneous cooling and heating operation controlling method comprises differently setting a cooling and heating reference range to decide main operation mode of the multi air conditioner system based on outdoor temperature, measuring the outdoor temperature to select the cooling and heating reference range based on the outdoor temperature, summing capacities of the indoor units where a cooling or heating operation is set to calculate cooling and heating ratio, and identifying part of the cooling and heating reference range corresponding to the cooling and heating ratio to decide the main operation mode of the multi air conditioner system.
