MOISTURE CONDITIONING DEVICE

Title:

MOISTURE CONDITIONING DEVICE

Document Type and Number:

WIPO Patent Application WO/2006/129644

Kind Code:

A1

Abstract:

A moisture conditioning device has a refrigerant circuit (50) including a compressor (53), a first adsorption heat exchanger (51) where an adsorption agent is carried, an expansion valve (55) whose opening is adjustable, and a second adsorption heat exchanger (52) where an adsorption agent is carried. A first batch operation and a second batch operation are alternately performed to feed moisture-conditioned air into a room, where, in the first batch operation, moisture in the air is adsorbed by the second adsorption heat exchanger (52) and moisture is discharged into the air by the first adsorption heat exchanger (51) and, in the second batch operation, moisture in the air is adsorbed by the first adsorption heat exchanger (51) and moisture is discharged into the air by the second adsorption heat exchanger (52). Further, the degree of opening of the expansion valve (55) is controlled. At the time the first batch operation is started, the expansion valve (55) is set to the degree of opening at which the preceding first batch operation is completed. At the time the second batch operation is started, the expansion valve (55) is set to the degree of opening at which the preceding second batch operation is completed.
