摘要： PROBLEM TO BE SOLVED: To facilitate air-cooling of a condenser and make the corrosion- resistant technique of a high grade unnecessary by employing hydrofluorocarbon refrigerant having no problem of destroying ozone layer as refrigerant. SOLUTION: Thin absorbing solution is supplied from an absorber 5 into a reproducer 3 through a solution heat exchanger 10 and a solution pump 7 to evaporate refrigerant in the regenerator 3 by heating the thin absorbing solution by heating gas supplied from an external source and condense the absorbing solution. On the other hand, the reproducer 3 is provided with a fractionater 8 at the outlet port thereof to liquefy evaporated refrigerant supplied from the regenerator 3 into the condenser 4 through the fractionater 8. Further, the refrigerant, liquefied in the condenser 4, is supplied into the evaporator 6 of an indoor machine 2 through an expansion valve 11 and is vaporized in the evaporator 6 by depriving heat of a room. The vaporized refrigerant is supplied from the evaporator 6 into the absorber 5 of an outdoor machine 1 while thick absorbing solution is supplied from the generator 3. In this case, hydrofluorocarbon is used as the refrigerant.

摘要： PURPOSE:To prevent the formation of a concentration boundary film and improve permeation efficiency of a selected solution component by making a selective permeation separation membrane by a wavy shape in a liquid separation system by a penetration gasification method using the permselective membrane. CONSTITUTION:Permselective membranes 7, 7' are made to be a wavy shape in a liquid separation apparatus composed of a high pressure side first chamber 1 to which a prescribed liquid mixture of a liquid to be selected and another liquid containing the liquid to be selected is supplied and a low pressure side second chamber 2 adjacent to the high pressure side first chamber 1 having the permselective membranes 7, 7' for penetration gas pressure between them. Since the liquid mixture supplied to the inside 11 of the high pressure side first chamber flows curvedly along the wavy planes of the permselective membranes 7, 7', a concentration boundary film on the surfaces of the selective permeation membrane 7, 7' is disturbed and the concentration boundary film is not formed. Also, owing to the wavy shapes of the permselective membrane 7, 7', the surface area (permeation surface area) of the membranes 7, 7' are enlarged and in this point, the permeation efficiency is improved.

CONSTITUTION:A braided body 3 is knitted together with a heat exchanger tube 1 made of a hollow string-like body as woof and cotton strings as warp 2a, 2b, 2c, and two lines of coagulative layer 5, 5 are formed by painting melted liquid of heat melting material on suitable place. Sequentially, a cylindrical bundle of heat exchanger tube 8 is formed by winding the braided body 3 around a cellular core 6 having many holes 7, 7.... And partition walls 9, 9 are formed out of coagulative body of the heat melting material by quick cooling after melting the coagulative layer, and a baffle plate 11 is formed in the bundle of heat exchanger tube 8 by pouring and hardening two-liquid hardening type synthetic resin between the wall. Consequently, the baffle plate 11 unified with the heat exchanger tube 1 is formed in the bundle of heat exchanger tube 8 by the simple method.
