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.

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.

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.
