Abstract (en)
The invention provides a heating dedicated air conditioner that, if performing test operation in a reverse cycle to that of the heating cycle, can prevent drain water from an indoor heat exchanger from overflowing a drain pan. The heating dedicated air conditioner comprises: a compressor ( 21 ); an indoor heat exchanger ( 42 ); an outdoor heat exchanger ( 23 ); an outdoor expansion valve ( 24 ), which is provided between one end of the indoor heat exchanger ( 42 ) and one end of the outdoor heat exchanger ( 23 ); a four-way switching valve ( 22 ) that switches between a first state, wherein a discharge side of the compressor ( 21 ) and an other end of the indoor heat exchanger ( 42 ) are connected and a suction side of the compressor ( 21 ) and an other end of the outdoor heat exchanger ( 23 ) are connected, and a second state, wherein the discharge side of the compressor ( 21 ) and the other end of the outdoor heat exchanger ( 23 ) are connected and the suction side of the compressor ( 21 ) and the other end of the indoor heat exchanger ( 42 ) are connected; an indoor fan ( 43 ), which ventilates the indoor heat exchanger ( 42 ); and a control unit, which controls at least the compressor ( 21 ), the outdoor expansion valve ( 24 ), the four-way switching valve ( 22 ), and the indoor fan ( 43 ); wherein, the control unit, in the test operation mode, switches the four-way switching valve ( 22 ) to the second state; and a drain water inhibited interval during which drain water inhibition control is performed, wherein the control unit operates the compressor ( 21 ) and stops the indoor fan ( 43 ), is provided to the test operation mode.
