Abstract: An absorption heating and cooling apparatus includes a generator for separating a dilute solution into a high temperature gaseous refrigerant and a refrigerant-absorbing liquid. The gaseous refrigerant is conducted to an absorber either directly (heating cycle) or indirectly by way of a condenser (cooling cycle). In a heating cycle, the hot gaseous refrigerant fed to the absorber heats a heat exchange fluid (e.g., for heating a room), whereupon the gaseous refrigerant condenses to a liquid. In the cooling cycle, the gaseous refrigerant is condensed into a cold liquid refrigerant in the condenser and is sent to the absorber wherein it cools the heat exchange liquid. In both the heating and cooling cycles, refrigerant-absorbing liquid conducted from the generator to the absorber is mixed with the liquid refrigerant therein following the heat-exchange step.

Abstract: In an absorption cooling system, a refrigerant condensate is converted to a refrigerant gas in an evaporator to achieve a cooling effect. The refrigerant gas is then converted into smaller bubbles in an inlet chamber of an absorber, and a mixture of those bubbles and lithium bromide solution is raised through a heat-exchange conduit to an outlet chamber of the absorber to cause the refrigerant gas to be absorbed by the lithium bromide. The lithium bromide which is diluted by the refrigerant gas is fed to a generator which separates the refrigerant from the lithium bromide. Residual refrigerant gas in the out let chamber of the absorber is returned to the inlet chamber.
