CONTROL METHOD OF MULTI SYSTEM AIR CONDITIONER

摘要

PURPOSE: A control method of a multi-type air conditioner is provided to improve cooling efficiency of all indoor units by preventing refrigerant from flowing in one direction. CONSTITUTION: A plurality of indoor units is connected to one outdoor unit. A part of multiple indoor units is not connected with the outdoor unit. The intake temperature of a compressor which is located in the outdoor unit is measured(301). The intake temperature of a compressor is compared with a preset target intake temperature(302). The opening degree of an electronic expansion valve which is located in the indoor unit which does not communicates with the outdoor unit is controlled according to a comparison result(303,304).
