Abstract: An air-conditioning apparatus includes a heat pipe, which performs heat exchange. The air-conditioning apparatus provides supply air in a set state (temperature, humidity) through a change in the flow passage of ventilation air and outside air by the selective opening/shutting of dampers, cooling the outside air by spraying mist, and cooling and humidifying the supply air. The cooling temperature and humidity of the supply air is controlled at a ratio of the ventilation air passing through a cooling coil and the ventilation air passing through a bypass passage. Using a bypass passage, ventilation air can directly move to an air supply block without the intervention of the cooling coil within a heat exchange block through which a ventilation air passes.

Abstract: An apparatus includes a flash tank, a medium temperature low side heat exchanger, a low temperature low side heat exchanger, a first compressor, a second compressor, and an ejector. The flash tank stores a refrigerant. The medium temperature low side heat exchanger uses the refrigerant from the flash tank to cool a space proximate the medium temperature low side heat exchanger to a first temperature.

The first compressor compresses the refrigerant from the low temperature low side heat exchanger. The second compressor compresses the refrigerant from the medium temperature low side heat exchanger. The ejector directs a mixture of the refrigerant from the first compressor and the refrigerant from the second compressor to the low temperature low side heat exchanger during a defrost cycle.
