<div>Hi all ,</div>
<div> </div>
<div>I am confused with last step i.e. finding out difference for each hour. </div>
<div> </div>
<div>This is what my understanding is :-</div>
<div> </div>
<div>Electric input to heat and electric inpur to cool gives the energy consumption of the compressor per hour.</div>
<div> </div>
<div>Thus total energy consumed for each compressor is equal to the sum of each hour for whole year.</div>
<div> </div>
<div>Thus energy saved is equal to annual energy consumed minus the total energy consumed by all the compressors.</div>
<div> </div>
<div>Am i correct??</div>
<div> </div>
<div>Has anyone done these calculation for a project...can you please share this exceptional calculation??</div>
<div> </div>
<div>Thanks,</div>
<div> </div>
<div>Pawan.<br></div>
