LIQUID RECEIVER AND EMPTYING TANK

The liquid receiver stores the refrigerant fluid in a cooling plant.

In a cooling plant with several evaporators, the liquid receiver is also a transition tank. When one or more evaporators are emptied and the refrigerant is not sent to other evaporators; it will remain stored in the receiver. When the evaporators start working again, the liquid level will decrease in the receiver. In plants where evaporators suffer large variations of charge, the liquid charge may vary considerably. Such variations require certain volume of compensation in the liquid receiver. In large plants with defreezing systems of hot gas an emptying tank is necessary, since during the defreezing one or more evaporators are imptied of liquid and the liquid is sent to an ordinary receiver tank placed in the upper part of the general liquid receiver. Our receiver and emptying tanks have a horizontal design, but they can be designed vertically if required.
The tanks have connections for liquid inlet/outlet, level display window, oil vent, connection to level pressure, air vent, manometer and security valve.
The tanks are statured under ASME code for recipients under pressure and tested at 25 kg/cm3.
Approval certificates from authority can be provided with low extra cost.

RULES FOR SELECTION

The dimension of receiver should be such so that 70% of its internal volume is available to store all services that can be emptied in the plant simultaneously. The remaining 30% will be a lung for normal working conditions of the installation.
In small plants with a few evaporators, the receiver will have a dimension so that its volume plus 50% of the internal volume of the condenser store all the refrigerant of the plant.
In large plants with several evaporators, the receiver must contain the regular storing load (1/3 of its internal volume) plus the liquid load in the evaporator/s which can occassionally be emptied simultaneously because of defreezing of repairing.
In plants of recirculating, the recirculating separator of low pressure can be used as emptying tank. The emptying tank should be 1 ½ the volume of the largest load of liquid to empty or defreeze.
