Air conditioning condensation drainage system

An air-conditioning condensate drainage system for air-conditioning units mounted on the roof structure of buildings, the roof structure having a roof membrane, comprising:

• elongate strips of material extending from said air-conditioning units and having an isolation membrane defining a bottom surface for assembly to a roof membrane and having an upper surface, said elongate strips of material defining substantially parallel side edges;
• a pair of ridges being integral with said substantially parallel side edges of said elongate strip of material and being disposed in spaced relation with one another and cooperating with said isolation membrane to define an air-conditioning condensate drainage channel between said ridges;
• a panel member of generally triangular configuration being fixed to the roof membrane and having side edges;
• ridges projecting upwardly from said side edges of said generally triangular panel member and being disposed in angular relation with one another and defining a condensate collection basin therebetween, said ridges defining at least one inlet opening within which a portion of said elongate strip of material is located and defining at least one outlet opening;
• and
• at least one condensate drain channel being in condensate draining communication with said condensate collection basin.

A method for installing an air-conditioning condensate drainage system on the roof structure of a building having one or more air-conditioning units, wherein the roof structure includes a roof membrane, said method comprising:

• affixing a condensate collection basin to said roof membrane, said condensate collection basin having an isolation membrane of generally triangular configuration and perimeter ridges of sufficient height to define a collection basin of sufficient volume to accommodate the condensate drainage from a plurality of air-conditioning units, said condensate collection basin defining at least one inlet in communication with the condensate drain channel structure and having an outiet;
• affixing at least one elongate strip of condensate drain material to the roof membrane along a desired drainage path from a plurality of air-conditioning units to said condensate collection basin, said condensate drain material defining a pair of spaced ridges defining a drainage path therebetween and being disposed in condensate supplying communication with said condensate collection basin;
• and
• affixing an elongate strip of condensate drain material to the roof membrane along a desired drainage path from said condensate collection basin to an in-roof drain of the roof structure, said elongate strip of condensate drain material having side edges and edge ridges projecting upwardly from said side edges.

An air-conditioning condensate drain channel structure, comprising:

• at least one strip of substantially solid material having a mounting base sutface having a generally triangular cross-sectional configuration, having opposed angulated side surfaces extending upwardly from said base surface and being disposed in upwardly converging relation and merging with a ridge top surface;
• at least one elongate ridge member projecting upwardly from said mounting base surface and having upwardly converging side surfaces and an upper surface intersecting said side surfaces;
• said at least one strip of material being of hollow construction defining an interior space and having a base wall and angulated side walls projecting upwardly from said base wall and being disposed in upwardly converging relation with one another, said at least one strip of material having a strip top wall being integral with each of said side walls;
• and
• an intermediate structural wall being located within said interior space and having spaced bottom edges being in integral connection with at least said base wall, said intermediate structural wall providing said at least one strip of material with enhanced structural integrity.

An air-conditioning condensate drain channel strip comprising:

• a drain channel ridge element having upwardly converging angulated side walls and an upper wall defining an internal ridge space;
• at least one base flange being integrally connected with at least one of said angulated side walls and adapting said drain channel strip for mounting to a roofing substrate;
• and
• an intermediate internal wall having side edges integrally connected with said angulated side walls and enhancing the structural integrity of said drain channel ridge element.
