<p>PURPOSE: To efficiently reproduce a liquid absorbent of a LiCl aqueous solution, etc., with small energy. CONSTITUTION: The LiCl aqueous solution L whose concentration becomes dilute after absorption of moisture in air, is heated by using a condenser 22 of a heat pump 20 and the heated LiCl aqueous solution L is introduced into an evacuated room 15 set to the atmosphere of lower water vapor partial pressure than its equilibrium water vapor partial pressure. The water in the LiCl aqueous solution is evaporated in the evacuated room 15 and is released and also the released water vapor is condensed by using an evaporator 24 of the heat pump installed in the room to produce water. Thus, the LiCl aqueous solution is reproduced to the original concentration and is utilized for recycling, in the absorption type humidifier.</p> |
