In the United States, the efficiency of air conditioners is often rated by the seasonal energy efficiency ratio (SEER) which is defined by the Air Conditioning, Heating, and Refrigeration Institute, a trade association, in its 2008 standard AHRI 210/240, Performance Rating of Unitary Air-Conditioning and Air-Source Heat Pump Equipment. [1]
In Europe, the seasonal efficiency of refrigeration equipment, chillers and air conditioners is often rated by the European seasonal energy efficiency ratio (ESEER) which is controlled (among others) by the Eurovent Certification Company. [1] A similar standard in the United States is the integrated energy efficiency ratio (IEER).
For air conditioners, the directive applies only to units under 12 kW. Every label contains the following information: the model, the energy efficiency category from A+++ to G, the annual energy consumption (full load at 500 hours per year) the cooling output at full load in kW
Every air conditioning system when evaluated by the test procedures for SEER and EER will provide some hopefully repeatable number. For that air conditioning system, these two ratings will have some ratio to each other. Accordingly, that ratio is fixed only by the SEER rating and the EER rating and is not affected by where the system is installed.
The coefficient of performance or COP (sometimes CP or CoP) of a heat pump, refrigerator or air conditioning system is a ratio of useful heating or cooling provided to work (energy) required. [ 1 ] [ 2 ] Higher COPs equate to higher efficiency, lower energy (power) consumption and thus lower operating costs.
The rating system consist of a scale ranging from A to E basis, where A represent the most efficient and E represent the least efficient rating. The rating scheme consider three aspects of buildings; Building envelope thermal performance; Lighting system efficiency; Installed power and air conditioning system efficiency
