-
Energy Efficiency Rating
-
Energy Efficiency Ratio
-
Energy Efficiency Reduction
-
Energy Efficiency Requirement
B
Correct answer
Explanation
The (EER) or Energy Efficiency Ratio measures the efficiency of an air conditioner by calculating the ratio of its cooling capacity in BTU per hour to the power input in watts.
What is the primary purpose of the (Energy Star) label on appliances?
-
To indicate energy efficiency
-
To promote sustainable manufacturing
-
To reduce carbon emissions
-
To ensure product safety
A
Correct answer
Explanation
