Patent number: 5509466Abstract: 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.Type: GrantFiled: November 10, 1994Date of Patent: April 23, 1996Assignee: York International CorporationInventors: William F.
