US Classification:

261097000, 261099000, 261DIG003, 261DIG043

Abstract:

A media pad for an evaporative cooler includes a plurality of superposed sheets of slit and expanded wicking paper joined together. A pressure drop across the media pad is less than about 0.25 inches of water at an air speed of 225 feet per minute and at about room temperature. A means for providing capillary dispersion of water having a Klemm greater than about 3 inches in 10 minutes is also disclosed. An evaporative cooling system including a housing having with an evaporative media pad that is flexible is also disclosed.

International Classification:

F28C 3/08
F25D 17/06
F25B 39/04

US Classification:

62 92, 62305, 62 89

Abstract:

An evaporative cooled condenser unit employs a quiet motor/fan system that pulls air across an evaporative media pad, through a drift eliminator and delivers cool air to a condensing unit of an air conditioner thereby increasing the operating efficiency of the air conditioner. A condenser enclosure into which the cool air is delivered is adjustable for various sizes of condenser units and contains a plurality of barometric dampers to provide failsafe operation and provide for external air flow to the condenser during heat pump operation or when the auxiliary cooling module is disabled.

Appl. No.:

6/706352

Inventors:

Donald W. Townsend - Phoenix AZ
Edward E. Routery - Phoenix AZ

Assignee:

Stellar Energy Systems, Inc. - Phoenix AZ

International Classification:

F24J 210

US Classification:

126438

Abstract:

A solar energy concentrator and collector having a concentrator made up of one or more anticlastic panels that feature a non-developable doubly curved surface. The panels are concave in the north-south direction and convex in the east-west direction. In one embodiment, the panels are formed to have parallel circular arcs in the north-south direction of increasing radius from the center of the panel to its edges and having a curved cross-section in the east-west direction. The concentrator reflects light to a narrow zone of concentration which moves within a plane in response to changes in the angle of incidence of sunlight thereon. A method for forming the specially shaped reflective fiber reinforced plastic panel is also disclosed.

Assignee:

Arvin Industries, Inc. - Columbus IN

International Classification:

H05B 102

US Classification:

219506

Abstract:

A heater assembly includes heating element for generating heat to warm a space to be heated. A heat sensor is provided sensing the temperature within the radiant heater assembly for automatically disabling the heater elements upon exposure of the sensor to temperature in excess of a predetermined threshold temperature. A tip-over switch is provided for disabling the heater elements in resonse to predetermined tilting movement of the radiant heater assembly relative to a normal upright position. Alert indicators are provided for indicating disablement of the heater elements upon actuation of either the heat sensor or tip-over switch.
