Abstract
An air conditioning process and apparatus includes absorption of water vapor in a circulating absorption liquid composed of an aqueous salt solution. The absorption liquid is regenerated by evaporative concentration by indirect heat exchange with a heating fluid in an evaporator. The water vapor produced in the evaporator is condensed in a condenser by indirect heat exchange with a cooling liquid which is mainly composed of the absorption liquid to be concentrated or which has already been concentrated in the evaporator. The water vapor pressure over the cooling liquid in the condenser is lowered by causing gas to flow in contact with the cooling liquid.
