CONDENSER/ACCUMULATOR AND SYSTEMS AND OPERATION METHODS

摘要

A condenser/accumulator (60) has a shell (62). A coolant flowpath extends from a coolant ( 144) inlet to a coolant outlet ( 1 46). An upper tube bundle (68) is within the shell, a first branch of the coolant flowpath passing through tubes of the upper tube bundle. A lower tube bundle (70) is within the shell, a second branch of the coolant flowpath passing through tubes of the lower tube bundle. A refrigerant flowpath extends from a refrigerant inlet (64) to a refrigerant outlet (66) and is in heat transfer relation with the coolant flowpath. There is a vertical gap (76) between the upper tube bundle and the lower tube bundle and comprising at least 50% of a free volume of a refrigerant space within the shell.
