Drainage management system for refrigeration coil

An air conditioning or refrigeration unit associated with air handling equipment, said unit comprising:

• a support structure;
• a heat exchanger, said heat exchanger mounted in said support structure;
• and
• a drain pan disposed beneath said heat exchanger in said support structure, said drain pan including a base portion having a sloped region and a channel, said channel defining a low point of said base portion, said drain pan further including a plurality of walls extending from said base portion, said plurality of walls including a first wall adjacent said channel and having a first port, said plurality of walls including a second wall adjacent said channel and have a second port whereby condensate from said heat exchanger which falls on said base portion may be drained through either said first port or said second port;
• and
• a secondary drain plug structured and arranged to be located in one of said first and second ports to provide a second drainage path higher than the other of said first and second ports.

An air conditioning or refrigeration system comprising:

• a compressor;
• first and second heat exchangers coupled with said compressor;
• and
• a support structure for supporting one said first and second heat exchangers, and a drain pan disposed beneath said one of said first and second heat exchangers, said drain pan disposed in said support structure, said drain pan including a base portion having a sloped region and a channel, said channel defining a low point of said base portion, said drain pan further including a plurality of walls extending from said base portion, said plurality of walls including a first wall adjacent said channel and having a first port, said plurality of walls including a second wall adjacent said channel and having a second port whereby condensate from said one of said first and second heat exchangers which falls on said base portion may be drained through either said first port or said second port, and a secondary drain plug structured and arranged to be located in one of said first and second ports to provide a second drainage path higher than the other of said first and second ports.

A support assembly for a heat exchanger in an air conditioning or refrigeration system comprising:

• a drain pan having a sloped region and a channel, said channel being in fluid communication with a drainage system;
• a plate disposed on said drain pan;
• and
• a baffle supported by said plate for supporting the coils of the heat exchanger;
• said baffle including a surface abutting a portion of said plate, said plate including a passageway for directing flow of condensate from the coils to said plate and to said drain pan whereby condensate which forms on the heat exchanger is effectively removed from the heat exchanger to said drain pan.
