Disclosed is a cooling-heating combination air conditioner being provided with an outdoor heat exchanger and an indoor heat exchanger in a single case. The present invention has advantages of freely adjusting a ventilation rate from 0% to 100% with its simple structure without equipping a separate ventilator, and improving efficiency in cooling and heating effectively by recovering an air discharged during a ventilation process and a waste energy of condensed water generated in the indoor heat exchanger and by maximizing a path along which a coolant is circulated according to cooling-heating mode conversion.
