PURPOSE:To prevent cold air feeling of a person due to the lowering of blow-off temperature and appropriately adjust air blow-quantity to increase air-conditioning efficiency by providing an air quantity control region controlling the indoor air quantity within a blow-out temperature range and an ability control region controlling the compression function to control the capacities of the blower and the compressor on indoor side. CONSTITUTION:The air quantity control region controlling indoor air quantity within the blow-off temperature range and the capacity control region controllin the compressor capacity are provided. When the temperature control is carried out, a compressor motor operates at a frequency as it is during the operation up to the blow-off temperature of 37 deg.C, when the blow-off temperature is lower than 37 deg.C, the frequency is lowered by 10Hz. Once the blow-off is lower than 37 deg.C, the frequency is increased, and when the blow-off temperature exceeds 40 deg.C, the frequency is restored to the original state. The fan motor is operated at a rotational speed of 900rpm up to the blow- off temperature of 40 deg.C, and the rotational speed of the fan motor is increased by 200rpm when the blow-off temperature exceeds 40 deg.C. Further, when the blow-off temperature rises up and exceeds 48 deg.C, the rotational speed is decreased by 200rpm. In the case where the blow-off temperature is lowered, when the blow-off temperature become lower than 40 deg.C, the rotational speed is lowered by 200rpm.
