DEHUMIDIFIER FOR REDUCTION OF OPERATIONAL COSTS

摘要

The present invention relates to a dehumidifying apparatus (100) for operation-saving use which is used for internal humidity control, and includes a dehumidification rotor (110) for absorbing moisture in the introduced air; A condenser 120 installed in an air flow path to the dehumidification rotor 110 for condensing the refrigerant compressed at a high temperature and a high pressure by the compressor 122; A regeneration fan 130 for discharging the air that has been dried by the dehumidification rotor 110 to the outside or circulating the air to the inside of the apparatus; A precooler (140) which evaporates the refrigerant expanded by the expansion valve to a low temperature and low pressure gas to absorb the ambient heat to cool the regeneration air circulated into the apparatus by the regeneration fan (130) or the outside air to be introduced; A drain pan 150 for collecting and collecting condensed water generated in the precooler 140; A heat exchanger (160) installed to lower the temperature of the air introduced from the precooler (140) and heat exchanged with the condensed water collected in the drain pan (150) against the air dehumidified by the dehumidification rotor (110); And an air supply fan 170 for discharging the air that has passed through the heat exchanger 160 and supplying the air to the room. According to the present invention, by eliminating the aftercooler and recycling the condensed water, the operation cost can be reduced in the summer and the facility capacity can be reduced. Therefore, the installation space can be minimized when the line is installed.
