Absorption refrigeration system using a heat transfer additive
Abstract
Abstract An apparatus and method for increasing the effectiveness of a heat transfer additive, such as, for example, 2-ethyl, n-hexanol, in an absorption refrigeration machine by introducing the refrigerant containing the additive directly from the condenser into a circulating stream of refrigerant being withdrawn from the evaporator, and being pumped to the evaporator refrigerant distribution system, thus distributing the additive flow from the condenser uniformly throughout the evaporator surface. Any noncondensables from the condenser are vented back to the absorber, where they are removed by a conventional purge device. Increased capacity can also be achieved by cooling the refrigerant with condensing water.
