Abstract

Disclosed herein is an air-conditioning apparatus using a heat pipe, wherein the heat exchange and mixed supply of outside air and ventilation air are effectively performed by comparing the state (e.g., temperature, humidity or wet-bulb temperature) of the outside air with the set state (e.g., temperature or humidity) of supply air, and supplying the 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 through latent heat by spraying mist, and cooling and humidifying the supply air. The energy of the air-conditioning apparatus can be reduced because energy efficiency can be improved using the evaporation latent heat of water. 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. Operation costs can be reduced and financial gains can be made because an efficient operation is performed.
