Energy Efficiency Ratio / Energie-Wirkungsgrad-Verhältnis

ENERGY EFFICIENCY RATING. This is a number assigned to every air conditioning unit based on how efficiently an AC unit uses up energy. This number is arrived at by taking the unit's BTU/hr divided by its electrical input in watts. The higher this number is, the more efficient the air conditioning unit is (and the more money it wills save you in the long run on your energy bill). Smaller units can have an EER up to about 11 while the most efficient larger model AC's can have an EER rating of up to 13. For example, an AC unit with an EER rating of 10 should use up to 20% less energy than a similar unit with an EER rating of 8.

See Chapter 12, Efficiency Ratings, for more information.

Energy Efficiency Ratio. Instantaneous efficiency of air conditioners measured at standard test conditions. The amount of cooling provided per unit of electricity purchased. The higher the EER, the more efficient the air conditioner.

Energy Efficiency Ratio. Standard air-conditioning performance rating, defined by the U.S.D.O.E. Air-Conditioning Test Procedure, equal to the ratio of cooling capacity in BTUs to the power input in watts at ARI rating conditions.

The ratio of cooling capacity of an air conditioning unit in Btus per hour to the total electrical input in watts under specified test conditions. California Code of Regulations, Section 1602(c)(6).

Energy efficiency ratio is a measure of how efficiently a cooling system will operate when the outdoor temperature is at a specific level (usually 95 degrees F). A higher EER means the system is more energy efficient.

Energy Efficiency Ratio. The ratio of the cooling capacity of the air conditioner, in Btu per hour, to the total electrical input in watts under test conditions specified by the Air-Conditioning and Refrigeration Institute.

Energy Efficiency Ratio. Cooling capacity in BTU/hr divided by electrical energy consumed in watts.

(energy efficiency ratio). A measure of cooling efficiency computer by dividing a cooling unitâ€™s output in BTUs by its input in watts.

(energy efficiency ratio): a measurement of the energy required by a cooling system as it attempts to maintain indoor comfort at a specific outdoor temperature - usually 95°F. The term EER is most commonly used when referring to window air conditioners and geothermal heat pumps. EER equals the number of Btu worth of cooling provided at the specified outdoor temperature divided by the number of watts used to provide that level of cooling.

Energy Efficiency Ratio is figured by dividing BTU hours by watts.

Energy Efficiency Rating. A measure of how efficiently an appliance uses energy. Determined by dividing the Btu per hour output by the number of watts used. A higher EER means greater efficiency.

Energy Efficiency Ratio (steady state)

Energy Efficiency Ratio. A measure of the energy efficiency of room air conditioners based on the U.S. Department of Energy guidelines.

Energy Efficient Ratio. The ratio of net equipment cooling capacity in Btu/h to total rate of electric input in watts under designated operating conditions. When consistent units are used, this ratio becomes equal to the coefficient of performance.

Energy efficiency ratio. An equipment efficiency rating that is determined by dividing the output in Btuh by the input in watts. This does not take into account the startup and shutdown for each cycle.

Energy Efficiency Ratio. The measure of the instantaneous energy efficiency of room air conditioners; the cooling capacity in Btu/hr divided by the watts of power consumed at a specific outdoor temperature (usually 95 degrees Fahrenheit).

Energy Efficiency Ratio means the ratio of the cooling capacity of the air conditioner in British Thermal Units per hour, to the total electrical input in watts under ARI-specified test conditions.

Energy Efficiency Ratings (EER) measure the efficiency with which a product uses energy to function. It is calcuated by dividing a product's BTU output by its wattage.

energy efficiency ratio - a factor calculated to determine how efficient a unit/system is.

Energy Efficiency Ratio The ratio of the cooling capacity of the air conditioner in BTUs per hour to the total electrical input in watts This measure is determined by comparing test units to the Air Conditioning and Refrigeration Institute specifications

A ratio calculated by dividing the cooling capacity in Btu's per hour (Btuh) by the power input in watts at any given set of rating conditions, expressed in Btuh per watt (Btuh/watt). EER & SEER can not be compared equally. Air source equipment is rated by SEER and geothermal equipment is rated by EER.

(Energy Efficiency Ratio) Calculated by dividing BTU hours by watts.

Energy efficiency rating. A number indicating the relative amount of energy consumed by a given appliance. The higher the EER, the more efficient it is.

See ENERGY EFFICIENCY RATIO.

Energy Efficiency Ratio. a measure of the cooling or air-conditioning efficiency of an appliance, calculated by dividing the cooling output in Btu/h by the energy input in watts.

Acronym for Energy Efficiency Ratio. This is a measurement of the efficiency of the cooling unit. It is calculated by comparing the Btu's to the watts of electricity consumed and the higher the efficiency rating the more efficient the unit. This benefits both environment and consumer as less energy is used which results in a lower operating costs.

Energy Efficiency Ratio. The ratio of the rated cooling capacity in BTUs per hour divided by the amount of electrical power used in watts at any given set of conditions.
