ABSTRACT:
An evaporator feed and control system maintains a relatively high level of stability over a wide range of varying loads. The evaporator system includes a first evaporator having a multiple pass inlet and a single pass outlet, and a second evaporator having an inlet and an outlet. The inlet of the second evaporator is connected to the output of the first evaporator. A control valve device is utilized for bypassing at least a portion of refrigerant-oil flowing in the first evaporator from the second evaporator directly to a suction line when system is operating at a reduced capacity.
