Precooler/Chiller/Reheater Heat Exchanger System

A system for drying and tempering flowing air, comprising:

• a first heat exchanger for precooling and subsequently reheating the flowing air;
• a second heat exchanger for chilling the flowing air below the incoming dew point thereof to remove moisture therefrom, the second heat exchanger disposed adjacent to the first heat exchanger such that the flowing air passes serially therethrough;
• a moisture removal section having an inlet and an outlet, the moisture removal section disposed adjacent to the second heat exchanger for removing entrained moisture from the air after it exits the second heat exchanger, the moisture removal section defined by sidewalls, the moisture removal section having a demister core disposed therein, the demister core disposed at an angle relative to at least one of the sidewalls to define an enlarged entrance area adjacent to the inlet and an enlarged exit area disposed adjacent to the outlet;
• means for providing refrigerant to the second heat exchanger including a distributor in fluid communication with the second heat exchanger for providing refrigerant to a second side of the second heat exchanger and a collector in fluid communication with the second heat exchanger for collecting spent refrigerant from the second side of the second heat exchanger;
• wherein said flowing air is compressed to a super atmospheric pressure prior to treatment by the system.

• a first crossover manifold for conveying air from the first heat exchanger to a first side of the second heat exchanger;
• a second crossover manifold for conveying air from said moisture removal section to a second side of the first heat exchanger;
• an inlet manifold for conveying warm, moist air to the first side of the first heat exchanger;
• an outlet manifold for conveying dried reheated air from the second side of the first heat exchanger
• wherein said flowing air is compressed to a super atmospheric pressure prior to treatment by the system.
