Energy Efficiency Ratio


The energy efficiency ratio of a particular product is determined by using the power input in watts to divide the cooling capacity of the same. The calculations are performed under a specific set of conditions. The output of the unit, whose energy efficiency is being calculated, is expressed in Btus per hour. In the calculations of the energy efficiency ratio the consumption of energy by the unit is given in watts.

The energy efficiency ratio is useful for the purpose of determining the seasonal energy efficiency ratio. Seasonal energy efficiency ratio is a parameter that is used in order to measure the cooling efficiency of an air conditioner. It has been observed that the efficiency of the air conditioner is directly proportional to the numerical value of the ratio.

Energy efficiency ratio is also useful for the purpose of finding out the energy efficiency of a cooling or heating unit. The energy efficiency ratio is useful in order to find out how well a cooling system would be functioning at a given temperature. The temperature that is used for the purposes of calculations, generally, is 95 degrees Fahrenheit.

The term energy efficiency ratio is applicable for the heat pumps as well in the way that the ratio can be used to measure its efficiency. The energy efficiency ratio can also be used for geothermal heat pumps and water-source. The concept of energy efficiency ratio also has some impact on the operating economy of a particular system.

Energy efficiency ratio is an important part of the concept known as thermodynamics. Thermodynamics is basically the division of chemistry and physics that deals with the impact of the alterations in the temperature, volume and pressure on a physical system. These are measured in the context of the macroscopic scale. It may also be described as the rating of efficiency of an equipment at a particular couple of internal and external temperatures.
