Title: Refrigeration system having improved heat transfer and reduce power requirement for various evaporative refrigerants

Patent ·
OSTI ID:5055602

A description is given of an improved refrigerating system of the type which includes (A) an evaporator for circulating a fluid refrigerate therethrough to absorb heat from a refrigerating medium, whereby said medium is cooled and said refrigerant is converted from a liquid to a gas, (B) an oil lubricated compressor connected in receiving relation to said evaporator for compressing and superheating said gas, (C) a condenser connected in receiving relation to said compressor for condensing said compressed gas to form a liquid, and (D) a receiver connected in liquid receiving relation to said condenser for storing said liquid and connected in liquid supplying relation to said evaporator, the improvement comprising (E) heat exchanger means having a liquid refrigerant confining shell and a heat exchanger tube disposed in said shell, an inlet end of said tube being connected in receiving relation to said compressor for receiving said compressed, superheated gas therein, said shell having an inlet port connected in receiving relation to an outlet port of said condenser for circulating a portion of the liquid refrigerant condensed in said condenser about said tube to partially desuperheat said compressed gas, and (F) an impurity removing oil-mist separator/collector unit connected in receiving relation to an outlet end of said tube for removing impurities, including oil, from said partially desuperheated gas, said unit being connected in supplying relation to said condenser for supplying cleaned, partially desuperheated gas to said condenser.
