Filed:

Appl. No.:

5/801082

Inventors:

Howard W. Cox - Tempe AZ

Assignee:

Mission Marketing Corporation of Arizona - Tempe AZ

International Classification:

F04D 2508

F24F 1300

US Classification:

98116

Abstract:

A ventilating damper assembly particularly adapted for use in conjunction with an evaporative cooler system for architectural structures includes a duct inserted into the ceilings of rooms cooled by the evaporative cooling system to discharge air from within the room through an attic space located above the ceiling and out into the atmosphere through vents in the attic. The ventilating damper assembly has a gravity-closed pivotally-mounted lid on the upper end of the duct to keep the duct closed whenever the evaporative cooling system is not in operation or whenever backdrafts from the attic occur. Positive air pressure within the room moves upwardly through the damper assembly, opening the lid to permit air to escape from the room into the attic, thereby maintaining the air flow necessary for efficient operation of an evaporative cooler and additionally exhausting the relatively cool air into the attic space above the ceiling to further improve the cooling efficiency of the system. Temperature sensitive normally-open self-closing anti-draft dampers close the duct whenever abnormally high temperatures occur.

International Classification:

US Classification:

Abstract:

A leg assembly for leveling a device, such as an evaporative cooler or refrigeration unit, on a pitched roof, includes an elongated leg member having first and second ends and first and second perpendicular sides for attachment to the device to be leveled. A foot having an "L" shaped configuration has a base for placement on the roof; and an upright portion which is attached to the leg member. The leg member has a series of equally spaced holes extending along the length of at least one of the sides; and that side is located in a plane which is the plane of the pitch of the roof. The upright portion of the foot member is attached to the lower end of the leg member through a resilient vibration isolation damper. In some installations, a second vibration isolation damper is placed between the leg and the device to be supported, to act both as a spacer and as a vibration isolation member, to reduce the amount of vibrations transmitted to the roof.

International Classification:

F24F 706

US Classification:

98 40C

Abstract:

An air deflection duct assembly is disclosed for use in adding an evaporative cooler unit to an existing refrigeration air conditioning duct to increase the efficiency of operation of the evaporative cooler by causing a higher percentage of the air flow from the cooler to pass into and through the existing refrigeration ducts. To accomplish this, first and second spaced apart duct assemblies are mounted over holes cut into the existing refrigeration air conditioning duct system. Each duct assembly has an adapter plate constructed with a circular hole in it, and this hole is normally closed by a pressure-opened deflector hinged at one edge of the hole. The hinged edges of the deflectors are mounted facing one another. When air is passed into the collar of the assembly extending upward from the hole from the evaporative cooler, the deflector plates open and extend at an angle into the existing refrigeration duct to deflect the air in opposite directions from the space between the openings cut in the duct. Thus, the evaporatively cooled air to moves into the preexisting refrigeration air conditioning duct in opposite directions from the installation of the first and second duct assemblies.
