<p>An air cycling type air conditioner comprising a heat exchanger (3), an air compressor (1) adapted to compress the suction air, transfer the compressed air to the heat exchanger (3), compress the air transferred from the heat exchanger (3) and transfer the resultant compressed air as supply air, an expander (4) adapted to expand the suction air, transfer the expanded suction air to the heat exchanger (3), expand the air transferred from the heat exchanger (3) and transfer the resultant expanded air as supply air, and a motor (2) for driving the compressor (1) and expander (4). The air-conditioner further includes a dehumidifier (10) for dehumidifying the suction air, a first temperature and humidity measuring member (12) for measuring the temperature and humidity of the suction air, and a control member (14) for calculating the amount of dehumidification on the basis of the temperature and humidity measured with the first measuring member (12) and requested temperature and humidity and controlling the dehumidifier (10) on the basis of the calculated amount. As the suction air is dehumidified by the dehumidifier (10) during room cooling operation, the water is not condensed even when the temperature of the air is lowered by the heat exchanger (3) and expander (4), whereby the efficiency of the air-conditioner as a whole is improved.</p> |
