Abstract
Abstract In the preferred form of this refrigerating system, the refrigerant condensing in the condenser is fed to the upper compartment of a receiver boiler in which a membrane having osmotic properties passes the liquid refrigerant into the lower compartment where it is vaporized by a heater. This vapor passes through the primary venturi passage of an aspirator which discharges into the top of the condenser. Some refrigerant liquefied in the condenser flows successively through one heat exchanger passage and a restrictor and an evaporator and the second passage of the heat exchanger to the low-pressure suction inlet of the aspirator.
