Air Conditioner Labeling

National Educational / Awareness Programme On

Standards & Labeling

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)

What Is Energy Consumption?

• We Pay Electricity Charges Based On “Units Of Consumption”

• 1 Unit = 1 kWh

• Example-1:- 10 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

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

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

• 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

Challenge Testing To Dissuade Tall Claims

Energy Labeling For AC Is In Voluntary Adoption Phase Now Became Mandatory

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

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
