Suggested Media Piping for Liquid Over Feed Refrigeration

The liquid feed solenoid valve when opened, allows liquid refrigerant to flow into the jacket of the heat exchanger. The

flow is regulated by a manually set flow control valve. Cooling is achieved when the pressure control valve is opened,

causing the pressure in the jacket to be reduced. This causes the liquid refrigerant to change phase, absorbing heat from

the heat exchanger tube and product. The cooling rate is controlled by the back pressure on the system and stops when the

valve is closed. Hot gas is used to push all of the remaining liquid from the system into the ammonia low pressure receiver

and quickly warm the system. The low pressure receiver in the compressor room is designed to separate the liquid from

the vapor before re-compressing.
