Abstract (en)
A simultaneous cooling-heating multiple type air conditioner includes a plurality of cooling-heating combined-use indoor units controlled in an operation domain divided into a plurality of operation zones based on a refrigerant suction pressure and a refrigerant discharge pressure of a compressor. The operation domain includes three operation zones. In the first operation zone, a cooling-initiative simultaneous cooling and heating operation mode is switched to a heating-initiative simultaneous cooling and heating operation mode. In the second operation zone, the cooling-initiative simultaneous cooling and heating operation mode or the heating-initiative simultaneous cooling and heating operation mode, does not switch to different modes. In the third operation zone, the heating-initiative simultaneous cooling and heating operation mode is switched to the cooling-initiative simultaneous cooling and heating operation mode.
