PURPOSE: An air conditioning system which performs heating and cooling is provided to prevent refrigerant from being accumulated in an outdoor heat exchanger. CONSTITUTION: An air conditioning system comprises a compressor, indoor heat exchangers(110,110'), an outdoor heat exchanger(210), and a refrigerant heating unit(300). The compressor compresses refrigerant. The indoor heat exchanger condenses the refrigerant compacted in the compressor in the heating mode. The outdoor heat exchanger evaporates the refrigerant condensed in the indoor heat exchanger. The refrigerant heating device heats the refrigerant condensed in the indoor heat exchanger. The refrigerant condensed in the indoor heat exchanger is heated with the refrigerant heating unit. A part of the refrigerant compacted in the compressor is selectively bypassed to the outdoor heat exchanger. |
