1 Eco 8, Practical intelligence Energy saving simulator with Altivar
2 Eco 8 estimates your energy savings in pumps & fans applications By adding a speed drive in your installation instead of electromechanical flow controlTaking into account all datas of your installationAs 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.
3 Eco 8 main benefitsThe tool provides financial figures for assessing the profitability of purchasing ALTIVARSimulate the possible savings on your installationsadding a variable speed drive instead of electromechanical devicesSelect the suitable Altivar product according to :The mechanical and electrical datasThe duty cycle of your installationCalculate how long it takes to get a return on your investmentEstimate how much reactive energy you could save
4 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.
5 Customise your Eco 8 tool Select :File,thenCustomiseSelect :Your languageYour currencyThe price of energy
6 Eco 8 allows you to describe your project Define the projectcharacteristicsSelect theapplicationDefine the electricalcharacteristicsDefine the air flowor water flowcycle timeGet the finalresults and ROI
7 Step 1 : Define the project characteristics Fill all the boxes
8 Step 2 : Select the application Choose you market :That will propose the right drive selection (ATV21 or ATV61)Selectfan or pumping
9 Step 2 : Some advices on pump datas With vane control, make the right choice according to your installation :HMT : Pump head at 0 flowZ : Total dynamic head = static head + friction head of installationFor transfert pump : Z ~ 0 (no static head)For high elevation, the ratio is closed to 0,85
10 Step 3 : define the electrical characteristics Choose the product protection :IP20 or IP54Select the voltageSelect the motor powerCurrent, cos phi, efficiency, price of electricity are filled automatically(could be adjusted)Select the price of total project
11 Step 3 : Some advices on installation price You have to give a price evaluation to your customer, but …………..you don’t know the price of installation !One of the method could be :Use the list price of the IP54 solutionThis price could represent the drive + installation cost
12 Step 4 : define the operating time Select the operating timereferenceFill the right cellsfor each flow rate
13 Step 4 : Some advices on cycle time All the final results are strongly linked to the cycle time, but sometimes, the customer doesn’t know the real cycle time !This software can give you only an estimation of the savings, that’s to say, to decide if it’s interesting to invest……So, if you don’t know the cycle, you can propose 2 simulations :One optimisticOne pessimisticThis is a simple way to limit the investigations
14 Step 5 : get the results Show the differences of energy consumption : with or without speeddriveShow reactive energy you could save with speeddrive- avoid the use of capacitors bank- reduce your energy penaltiesGive the time of return on investment(payback period, 1-2 years is acceptable)
15 Step 5 : Print your results To be integrated in the commercial proposal (Word file)To keep a record on your proposal
