Re: [TRNSYS-users] Tank losses in general and Type4



Michael,
I think you need to use an equation; divide the tank losses output by the tank volume.

Dear all,

I´m working with Type 4 to simulate a stratified storage tank.

I have a question due to my results. If the storage volume (liters) increases of course the absolute tank losses (Wh) are getting higher as well. But how can i show that the relative value decreases if the storage tank gets bigger? The literature says, that the relative tank losses decrease with a higher tank volume since the relation of volume to surface increases.

But even if I compare the "tank losses" to the "energy from heat source", the relative value gets higher with a bigger storage tank.


I am very thankful for any suggestions to answer this question.

Best,
Michael
