Problems solved by technology

However, since the absolute amount of moisture contained in the air is very small, it is impossible to make the supplied air into a state that is prone to condensation (increase the moisture content and increase the relative humidity), and there is a limit to the improvement of the dehumidification capacity.
[0005] In addition, when the room temperature is low as in winter, since frost adheres to the heat absorber (covered state), it must be operated while defrosting, and the dehumidification capacity is significantly reduced.

Abstract

A dehumidifying device achieves improved dehumidifying ability by having a body case (3) provided with a suction opening (1) and a discharge opening (2), a refrigeration cycle mechanism (4) provided in the body case (3), a fan (9) for sucking air into the body case (3) from the suction opening (1) and forming an air flow path in which the sucked air is sent to the discharge opening (2) after being passed through a heat dissipater (6) and a heat absorber (8) in that order, a moisture releasing section (11) of a dehumidifying rotor (10) located in the air flow path and provided between the heatdissipater (6) and the heat absorber (8), a moisture absorbing section (12) of the dehumidifying rotor (10) located in the air flow path and provided between the heat absorber (8) and the discharge opening (2), and a refrigerant heat exchanger (13) located in the air flow path and provided between the humidity discharging section (11) and the heat absorber (8).

Description

technical field [0001] The present invention relates to a dehumidifier equipped with a refrigeration cycle mechanism. Background technique [0002] A conventional dehumidifier of this type described in, for example, Patent Document 1 has the following configuration. That is, it includes: a main body case having an intake port and an exhaust port; and a refrigeration cycle mechanism provided in the main body case. The refrigeration cycle mechanism is composed of a compressor, and a radiator, an expander, and a heat absorber arranged downstream of the compressor in this order. Moreover, a blower is provided, and the blower blows the air sucked into the main body casing from the air inlet to the air outlet through the radiator and the heat absorber in sequence. [0003] Such a conventional dehumidifier is a device that dehumidifies indoor air by dehumidifying it by dew condensation in a heat absorber. In the refrigeration cycle mechanism, since refrigerant supplied to the co...
