Description

  The present invention relates to an indirect vaporization type air conditioner having an air conditioning core section in which a wet channel for generating a vaporization phenomenon and a dry channel for passing air to be cooled are partitioned by a base and alternately arranged. The present invention relates to an indirect vaporization air conditioning method.

  When the air is humidified, a vaporization phenomenon occurs and latent heat is taken away, whereby the temperature of the air is cooled to the wet bulb temperature of the air. However, at the same time, the air to be cooled is humidified. This principle is widely known as humidification cooling, and a vaporization-type cooler using it is widely made and sold. When humidification of the released air is not desired, the humidified cooling zone (wet channel) and the zone through which the air to be cooled (dry channel) is separated, and the temperature cooled in the humidified cooling zone is heat exchanged Thus, a method of transmitting only to the zone of the air to be cooled and cooling only the sensible heat of the air in the zone to be cooled, so-called indirect vaporization cooling is performed (see, for example, Patent Document 1).
