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.
Industry:Energy
A measure of the average amount of a specified pollutant or material emitted for a specific type of fuel or process.
Industry:Energy
A measure of the amount of light incident on a surface; measured in foot-candles or Lux.
Industry:Energy
A measure of the amount of energy lost during the generation, transmission, and distribution of electricity.
Industry:Energy
A measure of the ability of a light source to show colors, based on a color rendering index.
Industry:Energy
A measure of seasonal or annual efficiency of a central air conditioner or air conditioning heat pump. It takes into account the variations in temperature that can occur within a season and is the average number of Btu of cooling delivered for every watt-hour of electricity used by the heat pump over a cooling season.
Industry:Energy
A measure of light quality. The maximum CRI value of 100 is given to natural daylight and incandescent lighting. The closer a lamp's CRI rating is to 100, the better its ability to show true colors to the human eye.
Industry:Energy
A measure of air purity that is equal to one complete air change (in an interior space).
Industry:Energy
A means to increase the thermal efficiency of a steam electric generating system by increasing temperatures and interposing a device, such as a gas turbine, between the heat source and the conventional steam-turbine generator to convert some of the additional heat energy into electricity.
