Removal of worn or damaged gear and the fitting of new gear in replacement.

The amount (percent) of light that is reflected by a surface relative to the amount that strikes it.

Upwarddirected solar radiation, reflected by the earth's surface and the atmosphere.

Same as mirror nephoscope.

A rainbow formed by light rays which have been reflected from an extended water surface. Not to be confused with a reflected rainbow whose image may be seen in a still body of water. The center of a reflection rainbow is at the same elevation as the sun b ...

Materials with various qualities that are applied to glass windows before installation. These coatings reduce radiant heat transfer through the window and also reflects outside heat and a portion of the incoming solar energy, thus reducing heat gain. The ...

A window glass that has been coated with a reflective film and is useful in controlling solar heat gain during the summer.

An aluminum foil fabricated insulator with backings applied to provide a series of closed air spaces with highly reflective surfaces.

A material applied to window panes that controls heat gain and loss, reduces glare, minimizes fabric fading, and provides privacy. These films are retrofitted on existing windows.

Downward-facing pyranometer used for measuring reflected solar radiation.

In general, any object that reflects incident energy. Usually it is a device designed for specific reflection characteristics.

A type of incandescent lamp with an interior coating of aluminum that reflects light to the front of the bulb. They are designed to spread light over specific areas.

The change in direction of a ray of light when it passes through one media to another with differing optical densities.

A metal having an extremely high melting point, for example, tungsten, molybdenum, tantalum, niobium, chromium, vanadium, and rhenium. In the broad sense, this term refers to metals having melting points above the range for iron, cobalt, and nickel.

Media of heat transfer in a refrigeration unit. R12 and R22 are commonly used refrigerants.

The compound (working fluid) used in air conditioners, heat pumps, and refrigerators to transfer heat into or out of an interior space. This fluid boils at a very low temperature enabling it to evaporate and absorb heat.

The process of the absorption of heat from one location and its transfer to another for rejection or recuperation.

A measure of the effective cooling capacity of a refrigerator, expressed in Btu per hour or in tons, where one (1) ton of capacity is equal to the heat required to melt 2,000 pounds of ice in 24 hours or 12,000 Btu per hour.

The complete cycle of stages (evaporation and condensation) of refrigeration or of the refrigerant.

A device consisting of a heat transfer system, a moisture elimination system and a refrigeration system designed to improve the quality of the air and reduce the temperature of the air.
