Abstract
A dehumidifier includes a suction unit, a dehumidifying unit having a chiller, a discharge unit having a heat radiator, a refrigerant circulating system, and a heat exchanger. The suction unit sucks humid air into the dehumidifying unit, which cools the humid air and condenses the moisture in the humid air to create dry air. The discharge unit heats and discharges the dry air coming from the dehumidifying unit, and the heat exchanger exchanges heat between the humid air and the dry air coming from the dehumidifying unit. The refrigerant circulating system is used to cool the humid air at the dehumidifying unit and to heat the dry air at the discharge unit. In some embodiments, the heat exchanger includes a heat transfer unit, wherein flat plates are turned back alternately in opposite directions, and a first and second flow passage are prepared alternately in many layers between the flat plates.
