ABSTRACT:
An air conditioner coolant circulation route changing apparatus for improving efficiency of the heating operation during the heating operation and to prevent efficiency of its cooling operation from being deteriorated in case the heating operation is changed into the cooling operation, the air conditioner having dual functions of heating and cooling operations provided with a compressor for compressing a coolant into the coolant of high temperature and high pressure, an outdoor heat-exchanger for condensing the coolant of the compressor, a cooling capillary tube for expanding the condensed coolant at the outdoor heat-exchanger, an indoor heat-exchanger for changing the coolant into a perfect gas coolant of low temperature and low pressure and for getting heat-exchanged with the air flown into the room, the apparatus which changes the coolant circulation direction of the coolant flowing inside of the indoor heat-exchanger, regardless of heating or cooling operation, from inside of the indoor unit to the room air suction side, that is, the reverse direction to that of the air flowing into the indoor unit.
