Title:
MOISTURE CONDITIONING DEVICE
Document Type and Number:
WIPO Patent Application WO/2005/095868
Kind Code:
A1
Abstract:
A moisture conditioning device, wherein a refrigerant circuit (60) is formed by connecting a compressor (63), a four-way selector valve (64), a first adsorbing heat exchanger (61), an expansion valve (65), and a second adsorbing heat exchanger (62) to each other so that the circulation of a refrigerant can be reversed for performing a vapor compression refrigerating cycle. Adsorbent for adsorbing and desorbing moisture is carried on the surfaces of the first adsorbing heat exchanger (61) and the second adsorbing heat exchanger (62). To alternately adsorb and desorb the moisture by the first adsorbing heat exchanger (61) and the second adsorbing heat exchanger (62), the switching mechanism (four-way selector valve) (64) is switched to change the circulating direction of the refrigerant in the refrigerant circuit (60). In addition, before the circulation of the refrigerant is switched, the compressor (63) is stopped to lower a pressure difference between the high-pressure side and low-pressure side of the refrigerant circuit (60).
