A unitary air conditioner comprises a 1-stage thermostat (51) mounted in a room for generating an air conditioner ON/OFF signal, an indoor unit (53) configured to operate based on a signal from the 1-stage thermostat (51), and a variable-capacity outdoor unit (55) connected to the 1-stage thermostat (51) and the indoor unit (53). The variable-capacity outdoor unit (55) has variable operation stages, which are changed based on the previous operation state and the current operation state. When a unitary-capacity operation signal (Y) is inputted from the 1-stage thermostat (51), a start operation stage of an outdoor unit (55) is determined based on the combination of the operation stage of the outdoor unit (55) operated before the operation signal (Y) is inputted and the operation time in the stage, and the determined operation is performed. The 1-stage thermostat (51) can be connected to the variable-capacity outdoor unit (55) according to circumstances. Consequently, the present invention has the effect of accomplishing various applications and providing more pleasant air conditioned circumstances. |
