Abstract

PURPOSE:To effectively utilize the latent heat of evaporation in return gas and to make the reversible heat exchanger small size, by exchanging heat the return gas with the raw air, after the return gas is cooled with the latent heat of evaporation and inducing the return gas to the reversible heat exchanger, cooling the raw air.
