1. An equipment enclosure assembly in combination with mechanical equipment for building systems or processes comprising a heating or cooling element and a blower;
- said equipment enclosure assembly including;
an enclosure with an open top;
a chassis supporting the mechanical equipment, said chassis moveable between a lowered position in which said chassis and said mechanical equipment are retracted within said enclosure and a raised position in which said chassis and said mechanical equipment are raised relative to said enclosure to provide access to said mechanical equipment;
a cover mounted on said chassis over said mechanical equipment and advanceable into and out of covering relationship with said open top of said enclosure;
a positive pressure plenum formed in said enclosure when said chassis is advanced to said lowered position;
said blower positioned on said chassis and operable to pull air into said enclosure through one or more air inlet openings in said enclosure or said cover and past said heating or cooling element and then advance the air into the positive pressure plenum.

Abstract
An equipment enclosure system includes an equipment enclosure mounted through a hole in a roof and a chassis supporting the mechanical equipment and which is moveable between a lowered position within the enclosure and a raised position relative to the enclosure to provide access to said equipment. A cover mounted on chassis advances into covering relationship over the enclosure when the chassis is retracted.

7. A method of installing on a roof of a structure mechanical equipment for building systems or processes comprising a heating or cooling element and a blower, the method comprising:
-
a) providing an enclosure having an open top and a chassis moveable between a lowered position in which said chassis is retracted within said enclosure and a raised position in which said chassis is raised relative to said enclosure; b) installing the mechanical equipment in the enclosure and on said chassis such that access is provided to said mechanical equipment when said chassis is raised relative to said enclosure; c) mounting a cover relative to the enclosure which selectively covers the open top of the enclosure such that a positive pressure plenum is formed in said enclosure when said chassis is advanced to said lowered position; d) forming a hole through the roof; e) securing the enclosure to the structure such that a portion of the enclosure extends through the hole in the roof; and f) positioning said blower on said chassis such that the blower is configured to operate to pull air into said enclosure through one or more air inlet openings in said enclosure or said cover and past said heating or cooling element and then advance the air into the positive pressure plenum. - View Dependent Claims (8, 9, 10)

11. A method of installing on a roof of a structure mechanical equipment for building systems or processes comprising a heating or cooling element and a blower in which the roof includes a layer of insulation supported on roof decking, the method comprising:
-
a) providing an enclosure having an open top and a chassis moveable between a lowered position in which said chassis is retracted within said enclosure and a raised position in which said chassis is raised relative to said enclosure; b) installing the mechanical equipment in the enclosure and on said chassis such that access is provided to said mechanical equipment when said chassis is raised relative to said enclosure; c) mounting a cover relative to the enclosure which selectively covers the open top of the enclosure such that a positive pressure plenum is formed in said enclosure when said chassis is advanced to said lowered position; d) forming a hole in the roof extending at least down to the roof decking; e) forming a curb around the hole in the roof; f) positioning the enclosure on the roof such that at least a portion of the enclosure is recessed within the curb and into the hole formed in the roof; and g) positioning said blower on said chassis such that the blower is configured to operate to pull air into said enclosure through one or more air inlet openings in said enclosure or said cover and past said heating or cooling element and then advance the air into the positive pressure plenum.
