<p>PROBLEM TO BE SOLVED: To provide a gas conditioning system in which an effective use of low exergy heat source is achieved while reducing increasing in size.SOLUTION: A gas conditioning system 1 includes: a pre-temperature changing part 11 provided in a flowing order of a temperature adjusted gas A; a middle temperature changing part 12; a lower temperature changing part 13; means 51 for switching installation of the middle temperature changing part 12 between a large temperature difference heat medium CH and a small temperature difference heat medium W; means 52 for switching the small temperature difference heat medium W to be installed into the pre-temperature changing part 11 between those flowing the middle lead flow path 43 and those flowing not via the middle temperature changing part 12; and means 53 for switching the heat medium CH, W flowing in the middle lead flow path 43 between those flowing a pre-lead flow path 44 and a middle discharge path 26. At the time of cooling down the temperature adjusted gas A, the heat contained in the small temperature difference heat medium W can be used at maximum by installing the small temperature difference heat medium W into the middle temperature changing part 12 and the pre-temperature changing part 11. At the time of heating, two-step humidifying can be conducted by installing the large temperature difference heat medium CH into the lower temperature changing part 13 and the middle temperature changing part 12.</p> |
