<p>PROBLEM TO BE SOLVED: To lower a temperature of air while keeping a humidity approximately same as that of the outdoor air by using a heat exchange device in which a vaporization type latent heat exchanger and a sensible heat exchanger are combined.SOLUTION: A heat exchange device is provided with a first vaporization type latent heat exchanger 11 for lowering a temperature of intake air by utilizing latent heat in vaporizing water, and a first sensible heat exchanger 33 in which air intake directions are orthogonal to each other to exchange heat between the air taken in the orthogonal directions. The first sensible heat exchanger 33 is disposed at a downstream side of the air of the first vaporization type latent heat exchanger 11. The air having exchanged heat in the vaporization-type latent heat exchanger 11 and the outdoor air, exchange heat by the sensible heat exchanger 33. A temperature of the air from the sensible heat exchanger 33 can be lowered while keeping a humidity approximately same as that of the outdoor air.</p> |
