What is the primary factor that determines the energy efficiency of an air conditioner?
-
Refrigerant type
-
Compressor efficiency
-
Air filter quality
-
Thermostat settings
B
Correct answer
Explanation
The efficiency of an air conditioner is largely determined by the efficiency of its compressor.
Which of the following is (NOT) a recommended practice for using energy-efficient appliances?
-
Using appliances during off-peak hours
-
