Dehumidifier

Abstract

A dehumidifier comprises a suction unit 45 which humid air 47 is sucked in, a dehumidifying unit 43 having a chiller 56 and for cooling down the humid air sucked in and for dehumidifying by condensing the moisture in the humid air, a discharge unit 46 having a heat radiator 54 and for heating and discharging dry air 49 as dehumidified at the dehumidifying unit, a refrigerant circulating system 44 for cooling down the humid air at the dehumidifying unit and for heating the dry air at the discharge unit, and a heat exchanger 1 for performing heat exchange between the humid air and the dry air as dehumidified at the dehumidifying unit.

Description

technical field [0001] The present invention relates to a dehumidifier installed in a room such as a drying room to dehumidify room air. Background technique [0002] Conventional dehumidifiers humidify the air by vaporizing the liquid refrigerant, cooling the cooler with the heat of vaporization, cooling the humid air drawn from the outside by the cooler, and condensing moisture in the humid air by cooling. Dehumidification, the compressor liquefies the refrigerant, heats the dehumidified dry air with the condensation heat generated during the liquefaction, and then discharges the dry air to the outside. [0003] However, in the case of conventional dehumidifiers, since the temperature difference between the humid air sucked from the outside and the cooled and dehumidified dry air increases, the power consumption required for cooling during dehumidification and temperature rise after dehumidification varies. many questions. [0004] In addition, Japanese Patent Applicatio...
