Abstract: An evaporator (168) in a vapor compression system (14) (168) includes a shell (76), a first tube bundle (78); a hood (86); a distributor (80); a first supply line (142); a second supply line (144); a valve (122) positioned in the second supply line (144); and a sensor (150). The distributor (80) is positioned above the first tube bundle (78). The hood (88) covers the first tube bundle (78). The first supply line (142) is connected to the distributor (80) and an end of the second supply line (144) is positioned near the hood (88). The sensor (150) is configured and positioned to sense a level of liquid refrigerant (82) in the shell. The valve (122) regulates flow in the second supply line in response to the level of liquid refrigerant (82) from the sensor (150).
