Abstract: PURPOSE: An absorbing refrigeration machine is provided to achieve an improved heat or substance transfer performance while reducing the size and weight of the machine, and installation cost, by allowing the heat transfer section with a plasma hydrophilic-reformed surface to be mounted in a heat exchanger. CONSTITUTION: In an absorbing refrigeration machine consisting of an evaporator, an absorber and a condenser, a heat transfer section has a plasma hydrophilic reformed surface which is a plasma polymer film having a receding contact angle of 30 degrees or lower. Since the pipe with plasma hydrophilic reformed surface has a thin water screen formed at the surface of the pipe, heat transfer performance is improved due to the increased heat transfer surface area and decreased heat resistance.
