<P>PROBLEM TO BE SOLVED: To provide an ammonia absorption type refrigerating machine having a separation film of high mechanical strength and heat resistance. <P>SOLUTION: This ammonia absorption type refrigerating machine includes an evaporator 1 for evaporating ammonia liquid, an absorber 2 to which the ammonia vapor obtained in the evaporator 1 is guided for making the same absorbed by an ammonia aqueous solution, a heater 5 to which the concentrated ammonia aqueous solution obtained by the absorber 2 is guided for heating the same, a separator 6 to which the ammonia aqueous solution accompanying with water vapor heated and evaporated by the heater 5 and the ammonia vapor is guided for separating the ammonia vapor, and a condenser 4 to which the ammonia vapor obtained by the separator 6 is guided for condensing the same. Further, an inorganic film element 35 is disposed in the separator 6 to separate the ammonia vapor, and the inorganic film element 35 is made of a porous ceramic tube provided with a silicalite membrane on its surface. <P>COPYRIGHT: (C)2012,JPO&INPIT |
