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 In The Country Grooved Copper Tube Fin Design & Heat Transfer Coil & No. Of Rows Compressor

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

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

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
