Eco 8, Practical intelligence Energy saving simulator with Altivar
Schneider Electric 2 - M&D – Hieulle Sylvain – 2008/07/21 Eco 8 estimates your energy savings in pumps & fans applications By adding a speed drive in your installation instead of electromechanical flow control Taking into account all datas of your installation As the energy efficiency for fan or pump systems depends on the control method used, a speed drive is especially efficient when the system is running with partial flow.
Schneider Electric 3 - M&D – Hieulle Sylvain – 2008/07/21 Eco 8 main benefits The tool provides financial figures for assessing the profitability of purchasing ALTIVAR Simulate the possible savings on your installations adding a variable speed drive instead of electromechanical devices Select the suitable Altivar product according to : The mechanical and electrical datas The duty cycle of your installation Calculate how long it takes to get a return on your investment Estimate how much reactive energy you could save
Schneider Electric 4 - M&D – Hieulle Sylvain – 2008/07/21 ECO 8 is not a contractual tool The accuracy of the results is affected by the accuracy of the inputs datas. Results should be used only for estimating purposes. The results of this calculation program must not be used as the basis for guaranteed energy savings.
Schneider Electric 5 - M&D – Hieulle Sylvain – 2008/07/21 Customise your Eco 8 tool Select : Your language Your currency The price of energy Select : File, then Customise
Schneider Electric 6 - M&D – Hieulle Sylvain – 2008/07/21 Eco 8 allows you to describe your project Define the project characteristics Select the application Define the electrical characteristics Define the air flow or water flow cycle time Get the final results and ROI
Schneider Electric 7 - M&D – Hieulle Sylvain – 2008/07/21 Step 1 : Define the project characteristics Fill all the boxes
Schneider Electric 8 - M&D – Hieulle Sylvain – 2008/07/21 Step 2 : Select the application Choose you market : That will propose the right drive selection (ATV21 or ATV61) Select fan or pumping
Schneider Electric 9 - M&D – Hieulle Sylvain – 2008/07/21 Step 2 : Some advices on pump datas With vane control, make the right choice according to your installation : HMT : Pump head at 0 flow Z : Total dynamic head = static head + friction head of installation For transfert pump : Z ~ 0 (no static head) For high elevation, the ratio is closed to 0,85
Schneider Electric 10 - M&D – Hieulle Sylvain – 2008/07/21 Step 3 : define the electrical characteristics Choose the product protection : IP20 or IP54 Select the voltage Select the motor power Current, cos phi, efficiency, price of electricity are filled automatically (could be adjusted) Select the price of total project
Schneider Electric 11 - M&D – Hieulle Sylvain – 2008/07/21 Step 3 : Some advices on installation price You have to give a price evaluation to your customer, but ………….. you dont know the price of installation ! One of the method could be : –Use the list price of the IP54 solution –This price could represent the drive + installation cost
Schneider Electric 12 - M&D – Hieulle Sylvain – 2008/07/21 Step 4 : define the operating time Select the operating time reference Fill the right cells for each flow rate
Schneider Electric 13 - M&D – Hieulle Sylvain – 2008/07/21 Step 4 : Some advices on cycle time All the final results are strongly linked to the cycle time, but sometimes, the customer doesnt know the real cycle time ! This software can give you only an estimation of the savings, thats to say, to decide if its interesting to invest…… So, if you dont know the cycle, you can propose 2 simulations : -One optimistic -One pessimistic This is a simple way to limit the investigations
Schneider Electric 14 - M&D – Hieulle Sylvain – 2008/07/21 Step 5 : get the results Show the differences of energy consumption : with or without speeddrive Give the time of return on investment (payback period, 1-2 years is acceptable) Show reactive energy you could save with speeddrive - avoid the use of capacitors bank - reduce your energy penalties
Schneider Electric 15 - M&D – Hieulle Sylvain – 2008/07/21 Step 5 : Print your results To be integrated in the commercial proposal (Word file) To keep a record on your proposal
