Abstract

Method and device for conditioning a gas such as air, wherein the gas is cooled by means of a cooling circuit for dehydration of the gas by evaporation of a refrigerant in the evaporator (16) of the cooling circuit. The gas is conducted also through a treatment zone in a regenerative exchanger apparatus, in which moisture is delivered to a moisture absorbing drying agent. The cooling circuit comprises in addition to the evaporator (16) a compressor (26) and a condenser (24). The cooling circuit is regulated as to its effect so that the greatest cooling and dehydration effect is obtained without any formation of ice on the evaporator taking place.
