PURPOSE:To reduce the load in heat exchanging operation by installing a heat pipe unit in which a heat absorbing part is arranged at an upstream side of a heat exchanging unit and a heat discharging part is arranged at a downstream side of the heat exchanging unit. CONSTITUTION:Air Qw of high temperature and high humidity fed into a first chamber 3 is deprived of its heat portion by a heat absorbing part 11a of a heat pipe unit 11. Working liquid within a pipe 11c is evaporated and moved toward a heat discharging side 11b. Vapor of the working liquid is cooled by air Qb of low temperature and absolute low humidity flowed out from the other side 5b of a heat exchanging unit 5 and liquified. condensed latent heat is discharged into the air Qb to increase the temperature of the air Qb. The working liquid condensed and liquified is returned back to the heat absorbing side 11a. Air heat is absorbed at a heat absorbing side of a heat pipe unit, the air temperature is lowered and guided out into a heat exchanging unit. The heat absorbed at the heat absorbing side of the heat pipe unit is thermally transmitted to a heat discharging side of the heat pipe unit and discharged into air having a low vapor density fed out of the heat exchanging unit, and its temperature is increased, so that a heat exchanging characteristic in the heat exchanging unit is improved.
