COMPOSITE HOLLOW FIBER MEMBRANE MODULE FOR PURIFYING SUCTION LIQUID OF ABSORPTION REFRIGERATING MACHINE AND THE WATER HEATER AND COOLER

摘要

A composite hollow fiber membrane module for purifying a suction liquid of an absorption type refrigeration machine and a cold and hot water purifier is provided to prolong life of the module, simplify the module, and improve productivity by simultaneously using composite hollow fiber membranes with superior strength and water passing performance and using heat resistant polyurethane as an adhesive for bonding one sides of the composite hollow fiber membranes in a bundle shape. A composite hollow fiber membrane module for purifying a suction liquid of an absorption type refrigeration machine and a cold and hot water purifier comprises: composite hollow fiber membranes(B) formed by forming polysulfone resin thin films on a stiffener; and a heat resistant polyurethane resin(A) for bonding one sides of the composite hollow fiber membranes to each other in a bundle shape, wherein one ends of the composite hollow fiber membranes that are adhered by the heat resistant polyurethane resin are opened while the other ends of the composite hollow fiber membranes are closed. The composite hollow fiber membrane module further comprises a protection net(C) adhered onto surfaces of the composite hollow fiber membranes.
