<div> </div>
<div>Thank you for the suggestion. I'll use Type 534 - coiled, but can you suggest me which are usually used values for the "geometry factor for natural convection" and "geometry exponent for natural convection".</div>

<div>Best Regards</div>

<div>Martin,<br /> I would highly recommend that if at all possible you use Type534 from the TESS Storage Tank library in place of Type60. Type534 has an internal heat exchanger model that is far more robust than the one built in to Type60.<br /> Kind regards,<br /> David

<div dir="ltr">Dear TRNSYS users,
<div> </div>
<div>I'm trying to analyse the influence of the heat exchanger area on the solar fraction and collector efficiency.</div>
<div> </div>
<div>I'm using storage tank Type 60c with internal HX. Although I change the area and the length(keeping the outside diameter constant) I always get same results for the monthly solar fraction and efficiency - like there is no influence.</div>
<div> </div>
<div>What could be the reason for this? </div>
<div> </div>
<div>Best regards</div>
<div>Martin</div>
