The present invention relates to an energy saving air conditioning system for constant temperature and constant humidity control. The system includes a main duct with an internal space and sucking indoor air and outdoor air to blow the air to the indoor; a compressor, a first condenser connected to the compressor, a second condenser connected to the first condenser; an air conditioning unit having an expansion valve selectively connected to the first or second condenser, and a air-conditioning coil (evaporator); an evaporation type humidifier installed in the main duct to spray evaporated water and provided with at least one of the condensers; a heating unit provided in the main duct to increase the temperature of the air passing the main duct; a first direction switching valve controlling the flow of a refrigerant discharged from the compressor to pass the first condenser or not to pass the first condenser; and a second direction switching valve controlling the flow of the refrigerant discharged from the compressor to pass the second condenser or not to pass the second condenser. Therefore, the energy is saved since a separate heat source is not used for the air conditioning and humidifying operation or for the dehumidifying and heating operation. Since the entire length of the refrigerant pipe is shortened, the equipment is simple, and the installation costs can be reduced. |
