Abstract

A shell-and-tube evaporator of a refrigerant system includes a refrigerant inlet distributor that traps a pocket of gaseous refrigerant to displace liquid refrigerant underneath the evaporator's tube bundle, thereby reducing the total charge of refrigerant in the evaporator. In some embodiments, the distributor comprises four sections interconnected by a central refrigerant feed line, which properly apportions the refrigerant to the four sections.
