Abstract

The condenser has a condenser shell with a reservoir portion, condenser tubes for cooling vapor flowing over the condenser tubes to condense the vapor to a liquid, and subcooler tubes in a subcooler compartment for cooling liquid within the reservoir portion. The condenser includes a drainage member for forming a void in the reservoir portion and having an upper surface inclined relative to a horizontal plane for directing the liquid from the condenser tubes toward the entrance to the subcooler compartment. The drainage member reduces the amount of liquid required in the reservoir for efficient subcooler and system operation by occupying space in the liquid reservoir that normally is occupied by liquid.

Dependent claims

A condenser comprising:

a condenser shell having a reservoir portion;
a vapor inlet through which vapor enters the condenser shell;
condenser tubes for cooling vapor flowing over the condenser tubes to cause the vapor to condense to a liquid and flow into the reservoir portion;
subcooler tubes for cooling liquid in the reservoir portion;
a subcooler compartment for housing the subcooler tubes, the subcooler compartment having an entrance through which the liquid within the reservoir portion flows into the subcooler compartment and over the subcooler tubes;
and
a drainage member for forming a void in the reservoir portion and having an upper surface inclined relative to a horizontal plane for directing the liquid from the condenser tubes toward the entrance to the subcooler compartment.
