Abstract
An absorption refrigeration system incorporating a novel solution flow control is disclosed. The solution flow control includes a sensor, preferably in the form of a float which senses the level of the solution in the absorber of the system. The signal from the level sensor is utilized to position a valve for controlling the flow of weak solution in such a manner that the solution flow increases/decreases as the level of the solution in the absorber decreases/increases. The solution control not only provides improved efficiency of the refrigeration system but also protects the system from the risk of crystallization of the solution. In one embodiment, a compact solution control is fully enclosed by an air-tight shell of the absorber and comprises a float, a rod mechanically and drivingly coupling the float with a solution valve so that the buoyancy of the float directly positions the valve. This arrangement does not need to meet the requirement of having an air tight structure and assures a long life in use.
