1. Air Conditioner Labeling
National Educational / Awareness Programme On
Standards & Labeling

2. Basic Terms For Air Conditioners
Cooling Capacity
Amount Of Cooling Produced By The AC
Units Used: TR, Btu/hr, kCal/hr, Watts
1TR = 12,000 Btu/hr = 3,024 kCal/hr = 3,514 Watts
Power Consumption
Electrical Power Consumed By Electrical Equipment Used In AC
= Compressor + Fan Motor
Split ACs Use 2 Fan Motors Totally
Unit Used: Watts (W), Kilo Watts (kW)

3. What Is Energy Consumption?
We Pay Electricity Charges Based On “Units Of Consumption”
1 Unit = 1 kWh
Example-1: Nos of 100 Watts Bulb Turned ON For 10 Hours Will Consume
10Nos x 100W x 10 Hrs = 10,000 Wh
= 10 kWh = 10 Units
Example-2:- Electrical Appliance Having 2,000 W Power Input And Continuous Operation Of 8 Hours Will Consume
2,000W x 8 Hrs = 16 kWh = 16 Units

4. Energy Efficiency Ratio (EER) For Air Conditioners
EER Of AC = Cooling Capacity (Watt) / Power Consumption (Watt)
EER Of 1TR (3,514 W) Capacity AC Consuming 1,500W Power =
3,514 / 1,500 = 2.34
Star Rating System As Of Now Based On EER
Star-1: 2.3, Star-2: 2.5, Star-3: 2.7, Star-4: 2.9, Star-5: 3.1
EER Can Be Improved By Increasing Cooling Capacity Or Reducing Power Input Or Both Through
Increasing Heat Exchanger Surface Area Of Indoor Unit & Outdoor Unit
Optimizing Heat Transfer coefficient on both the air and refrigerant side and also reducing air leakages
Use Of High Efficiency Compressor & Fan Motors
Higher number of Stars Means Higher Incremental Cost Difference
International Market: Average Rs.1,500 Per Star
India Market As Of June’08: Average Rs. 750 – 1,000 Per Star

5. Situation Before Energy Labeling
Testing Methods Different
No Monitoring Agency; No Way To Check Claims
Lack Of Clarity To Customers – With So Many Claims
Energy Not Really Getting Saved In The Country
Grooved Copper Tube
Fin Design & Heat Transfer
Coil & No. Of Rows
Compressor

6. Standards Comparison BIS Norms BEE Norms
The capacity of the production unit as determined on the room side shall be not less than 90% of the name plate rating
Maximum power consumption specified in the standard
the measured cooling capacity shall be > 0.95 of the rated value
the measured energy consumption shall be < 1.05 of the rated value
the measured EER shall be > 0.95 of the rated EER
Monitoring & Controlling System In Place

7. Situation In Labeling Scenario
NABL Accredited Common Test Lab For All OEMs
Standardized Test procedure
Monitoring System & Agency In Place
Gain Customer Trust In Labeling
Save Significant Energy For Our Country
Challenge Testing To Dissuade Tall Claims
Energy Labeling For AC Is In Voluntary Adoption Phase Now Became Mandatory

8. Current & Practical Approach To Labeling
If EER Value Of AC Is
What Star Will The Mfr. Declare?
2.68
2 Star
3.1
4 Star
Manufacturers Will Prefer To Keep Safety Margin For Production Deviations
BEE Has An Audit Check System In Place To Take Action Against Claims

9. Labeling Helps Whom?? Labeling Helps The Whole Value Chain
OEMs – Improved Top Line & Bottom Line, Product Differentiation
Channel Partners – Improved Margins
End Users – Savings In Monthly Energy Bill, Faster Paybacks
Our Country / Government – Huge Reduction In Energy Demands
BEE Has Specific Programs To Engage OEMs, Channel Partners And End-users To Move The Labeling Program Forward

10. Energy Saving Potential India Air Conditioners Labeling Program
Kaiga plant: 3 reactors of 220MW each = 660MW
1 more 220MW under construction
Tarapore: 2 * 160 = 320MW boiling water reactors
2 * 540MW = 1080MW Pressurised heavy water reactor
Kalpakkam Nuclear Plant Generation Capacity: 440MW. Cost: Rs. Xxxx Crores
Neyveli Thermal Plant Generation Capacity: 2,490MW. Cost: xxxx Crores

11. User Benefits Of Star AC Need To Be Conveyed At Point Of Sale
Kaiga plant: 3 reactors of 220MW each = 660MW
1 more 220MW under construction
Tarapore: 2 * 160 = 320MW boiling water reactors
2 * 540MW = 1080MW Pressurised heavy water reactor

12. Role Of Channel Partners
Provide Correct Information On Labeling To Customers
Guidance In Choosing “Higher Star” AC
Interfacing Between Customers & OEMs
Spreading Awareness On Star Labeling

13. Promoter Card
Pocket Book For Show Room Salesmen To Explain Labeling To Customers
Covers The Following:
Essence Of Energy Label
How It Impacts Air Conditioner Performance
Energy Bill Saving & Payback Calculation

14. Promoter Card Star Label & Impact On Air Conditioner Performance
Energy Meter Unit Consumption (kWhr) Depends On Input Power (kW) Of Labeled AC
Power = Capacity / COP
For 5 Star 1.5TR AC
= 5271W / 3.2
= 1650 W
