Abstract:
1. An absorption cooling system of the type including a liquid absorbent that remains in a liquid phase throughout an operation cycle, and a refrigerant having both a liquid phase and a vapor phase in said cycle, a basic system being powered by heat extracted from a hot fluid and powered auxiliary components, the system including five basic components of a generator, an economizer, a condenser, an evaporator and an absorber, and further including a fluid circuit for a rich solution including a circulation pump, a fluid circuit for a lean solution, and for a refrigerant gas extracted from said liquid absorbent and replaced therein, partial circuits for hot fluid and for cooling fluid, a jet mixer operating to mix saturated refrigerant gas with said lean solution to re-form said rich solution, the improvement comprising installing means for increasing pressure of a saturated refrigerant gas flowing from said evaporator to said jet mixer.
