Tonnage of Air conditioner

Energy Efficiency Ratio for AC:

• EER = cooling capacity / Power consumption (both in Watt)

 Cooling capacity of ONE tonne AC is 3514 Watts &

If Actual power consumption 1,500 Watts

• EER of 1 TR (about 3,514 W) capacity air conditioner = 3,514/1500 = 2.34

Star Rating System based on EER –

.    1-Star: 2.3

• 2-Star: 2.5 
• 3-Star: 2.7 
• 4-Star: 2.9 
• 5-Star: 3.1
