Title:
MOISTURE CONDITIONING DEVICE
Document Type and Number:
WIPO Patent Application WO/2005/098322
Kind Code:
A1
Abstract:
A moisture conditioning device, wherein a compressor (63), an expansion valve (65), and two heat exchangers (61) and (62) carrying a moisture adsorbable/desorbable adsorbent are connected to each other and the circulation of a refrigerant in a refrigerant circuit (60) for performing a refrigerating cycle is switched to alternately adsorb/desorb moisture by the heat exchangers (61) and (62). A liquid storage device (66) sucking an excess liquid refrigerant in a high-pressure state when the circulation of the refrigerant is switched is installed in a high-pressure line always brought into a high-pressure state by a directional control circuit (72). Also, the device comprises a circulation switching part (91) switching the circulation of the refrigerant after the fans of the heat exchangers (61) and (62) used as condensers are stopped for a specified time. Thus, since the excess liquid refrigerant is not present in a low-pressure line switched to a low-pressure state, the liquid refrigerant can be prevented from flowing into the compressor (63).
