Flooded-gas shut-off leg

The system shown in Fig. 10-13 similar to that shown in Fig. 10-12. However, the liquid leg evaporator dump right in the surge without a safety valve. In this system, the valve C a defrost controller. It is placed in the suction line, where he usually works. During defrost, the valve C change the mode defrost controller. In such a system, it is recommended to large capacity of the separator or valve is used as a bypass valve. It will bleed defrost pressure gradually around the valve C in the suction line. Notice how the line check valve is used to prevent cross flow.
