EER stands for Energy Efficiency Ratio. This term is specifically used to measure the efficiency of cooling devices, such as air conditioners and heat pumps. The ratio is defined as the cooling output (measured in BTUs) divided by the energy input (measured in watts) during a specific test period. A higher EER indicates a more efficient appliance, which is particularly important for consumers looking to reduce their energy consumption and associated costs. Understanding EER is crucial for the selection and evaluation of HVAC systems, as it directly impacts energy usage, operational costs, and environmental considerations within energy management practices.
