Abstract

A method of cleaning an HVAC coil unit located above a drain basin comprises providing a supply and collection assembly having a reservoir containing liquid cleaning solution, a pump operative to output the liquid cleaning solution through a supply outlet, and a vacuum source operative to draw in used liquid cleaning solution through a collection inlet. A nozzle device is in fluid communication with the supply outlet. A fluid return tool is in fluid communication with the collection inlet, and positioning the fluid return tool in the drain basin. A filter assembly is located between the fluid return tool and the collection inlet in the fluid return path. A further step of the method involves moving the delivery face of the nozzle device across the surface of the HVAC coil unit to deliver the cleaning solution into areas between fins thereof.

Abstract

An apparatus for cleaning an HVAC coil unit comprises a supply and collection assembly with a housing defining an interior space for containing a quantity of cleaning solution. A pump has an inlet positioned to be in fluid communication with the cleaning solution and is operative to deliver the cleaning solution to an outlet of the supply and collection assembly in a volume of at least 40 gallons per minute. Fluid return piping defines a conduit to conduct used cleaning solution from the HVAC coil unit back to a collection inlet. A filter assembly is positioned along the fluid return piping to filter the used cleaning solution. A fluid flow device is operative to provide pressure to move a quantity of the used cleaning solution through the fluid return piping. The used cleaning solution is returned to the interior space through the collection inlet during operation of said fluid flow device.

Abstract

An apparatus for cleaning HVAC cooling coils comprises a supply and collection assembly having a housing defining an interior space for containing a quantity of cleaning solution. A pump has a pump inlet positioned to be in fluid communication with the cleaning solution and is operative to deliver the cleaning solution to a supply outlet of the supply and collection assembly. A vacuum source has a vacuum inlet positioned to be in fluid communication with an ullage space above the quantity of cleaning solution such that the vacuum source creates negative pressure in the ullage space during operation. A collection inlet is in fluid communication with the ullage space such that the cleaning solution is returned to the interior space through the collection inlet during operation of the vacuum source. A nozzle device is in fluid communication with the supply outlet via outlet piping so as to deliver the cleaning solution to a surface of an HVAC coil unit. A fluid return tool is in fluid communication with the collection inlet via return piping so as to collect used cleaning solution from the HVAC coil unit.
