摘要： PURPOSE:To adsorb and evaporate refrigerant continuously and improve an operating efficiency jumpingly by a method wherein a cooling chamber is formed at one side of a film having multitude of fine through holes while a heating chamber is formed at the other side of the film. CONSTITUTION:Refrigerant vapor, supplied into a cooling chamber 2, is adsorbed into the fine through holes 8 of a film 1 to liquefy it while latent heat, dissipated upon liquefying, is removed by a cooling pipe 10 arranged in the cooling chamber 2. The liquid of the refrigerant moves through the through holes 8 by a temperature difference between the cooling chamber and a heating chamber as well as capillary phenomenon and enters into the heating chamber 3, heated by a heating tube 11, through a hole 9 so as to be evaporated. The refrigerant vapor in the cooling chamber 2 is made to flow sequentially into the through holes 8 to adsorb it accompanying the evaporation of the refrigerant solution in the through holes 8. The refrigerant vapor in the heating chamber 3 enters into a condenser 4 and is cooled here so as to be condensed and liquefied. Subsequently, the liquefied refrigerant is choked by an expansion valve 5 to effect adiabatic expansion and, thereafter, enters into a heat exchanger 6 so as to be evaporated by cooling a refrigerating load and circulated into the cooling chamber 2 again under this condition.
