Abstract: A multi type air-conditioner is provided. The multi type air conditioner includes an outdoor unit having a plurality of outdoor heat exchangers that heat-exchanges with outdoor air and a compressor that compresses a refrigerant; a plurality of indoor units that performs either cooling or heating; a high pressure pipe connected between a discharge side of the compressor and the plurality of indoor units; a low pressure pipe connected between a suction side of the compressor and the plurality of indoor units; and a refrigerant exhauster provided between the high pressure pipe and the low pressure pipe. The refrigerant exhauster discharges a liquid refrigerant to the low pressure pipe when the liquid refrigerant is accumulated in the high pressure pipe, whereby degradation of cooling capability due to a lack of refrigerant may be prevented by minimizing accumulation of the liquid refrigerant in the high pressure pipe in a cooling operation mode.

Abstract: The present invention discloses an air conditioner having multiple outdoor units, including a plurality of outdoor units disposed outdoors, at least one indoor unit connected to the plurality of outdoor units through refrigerant tubes, for exchanging heat with indoor air, and when part of the outdoor units are operated, a control unit for storing refrigerants in non-operated outdoor units, so that a proper amount of refrigerants can be supplied to the operated outdoor units. The air conditioner having the multiple outdoor units can improve performance and durability by preventing the refrigerants from being excessively concentrated on the operated outdoor units.
