Flooded recirculator

The bottom of the hot gas feed

Several system shown in Fig. 10-20 shows the return valve is installed in each of the liquid refrigerant branches. One solenoid valve is used in the main line of the refrigerant. Defrost gas from below.

Top gas supply

The system is shown on Fig. 10-21 shows valve is mounted directly on the outlet of each fluid-solenoid valves. Defrost gas-the fed. This system allows selective thawing of each evaporator. One accumulator is used to protect the compressor during thawing, and also to accumulate as liquid refrigerant and thawing of condensate. This protection is implemented using differential pressureregulator valve in the bypass circuit evaporator.

Differential pressureregulator valve is opened enough to relieve excess pressure at the compressor inlet.

Discharge pressure as excess pressure drop occurs. When the pressure drop is less than the regulator valves, the regulator should be tightly closed.
