PURPOSE: An energy-saving air conditioning system is provided to reduce energy consumption by supplying hot water from a cooling tower to a pre-heating/pre-cooling coil unit to increase the dry-bulb temperature of exterior air. CONSTITUTION: An energy-saving air conditioning system comprises a filter(110) which filters foreign materials from exterior air, a pre-heater(120) which preheats exterior air in the winter, a pre-heating/pre-cooling coil unit(130) which controls the temperature of exterior air, a water spray type humidification unit(140), a reheating coil unit(150), and a blower(160). The hot water delivered from a cooler(210) for cooling the air circulating in a clean room(200) to a cooling tower(220) is supplied to the pre-heating/pre-cooling coil unit so that the dry-bulb temperature of exterior air increases over 19°C by passing through the pre-heater and the pre-heating/pre-cooling coil unit. The reheating coil unit and the blower maintain the temperature and humidity of exterior air at 12°C and 90%, respectively.
