Energy Efficient Ratio Meaning

The energy efficiency ratio (EER) is a measure of how efficiently a cooling system uses energy to cool a space. It is calculated by dividing the cooling capacity of the system (in British thermal units, or BTUs) by the amount of energy it consumes (in watts). The higher the EER, the more efficient the system is. An EER of 10 or higher is considered very efficient, while an EER of 8 or lower is considered inefficient. The EER can be used to compare the energy efficiency of different cooling systems, and to determine which system is best for a particular application. It is important to note that the EER is only one factor to consider when selecting a cooling system; other factors such as noise level, installation cost, and maintenance requirements should also be taken into account. By taking all of these factors into consideration, you can ensure that you select the most energy-efficient cooling system for your needs.
