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. That mixture is returned to the generator along a path in which it travels in heat exchange relationship with the refrigerant-absorbing liquid being conducted to the absorber.
