Abstract

A humidity controller (10) is provided with a refrigerant circuit (60). The refrigerant circuit (60) has first and second heat exchangers (61, 62) carrying an adsorptive agent and circulates a refrigerant to perform a freezing cycle. Further, in the refrigerant circuit (60), the direction of circulation of the refrigerant is reversible. The first and second heat exchangers (61, 62) are installed in a casing (11). In the humidity controller (10), air flow paths are switched so that first air passes through either of the heat exchangers (61, 62) that works as an evaporator and second air passesthrough the other that works as a condenser. A compressor (63), an expansion mechanism (65), and a four-way selector valve (64) of the refrigerant circuit (60) are installed in the casing (11) together with the heat exchangers (61, 62).

Description

technical field [0001] The present invention relates to a humidity control device for adjusting the humidity of air, in particular to a technique for performing refrigeration cycle for regeneration and cooling of adsorbent. Background technique [0002] Conventionally, for example, there is a humidity control device disclosed in Patent Document 1 that uses an adsorbent and a refrigeration cycle to adjust the humidity of air. The humidity control device has two adsorption units. Each adsorption unit includes a mesh container filled with an adsorbent and a refrigerant tube of a drum mesh container. The refrigerant pipes of each adsorption unit are connected to a refrigerant circuit that performs a refrigeration cycle. The humidity control device is provided with a damper for switching the air sent to each adsorption unit. [0003] During the operation of the humidity control device, the compressor of the refrigerant circuit is operated, and a refrigeration cycle is performe...
