You will need quite a bit of PCM for substantial differences (.gt. 1 to 2 K), probably.</div><div><br></div><div>Which PCM model are you using? I think the basic "53" model cannot really take different temperatures for melting/solidification into account.</div><div><br></div><div>A simple approach for testing: If you have two otherwise identical surfaces, put the PCM in one and then look at the temperature profiles for a day for these surfaces (or split one of the PCM surfaces into two and remove the PCM from one of these). This should quickly give you an idea on if something is happening ("something" may be disappointingly small temperature differences).</div><div><br></div><div>Best</div><div>Achim</div><div><br></div><br><div><blockquote type="cite"><div lang="DE-CH" link="blue" vlink="purple" style="font-family: Helvetica; font-size: medium; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: -webkit-auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; "><div class="WordSection1" style="page: WordSection1; "><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; "><span style="font-size: 10pt; font-family: Arial, sans-serif; "> </span><o:p></o:p></div><div><div style="border-style: solid none none; border-top-width: 1pt; border-top-color: rgb(181, 196, 223); padding: 3pt 0cm 0cm; "><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; "><b><span lang="DE" style="font-size: 10pt; font-family: Tahoma, sans-serif; ">Von:</span></b><span lang="DE" style="font-size: 10pt; font-family: Tahoma, sans-serif; "><span class="Apple-converted-space"> </span><a href="mailto:esp-r-bounces@lists.strath.ac.uk" style="color: purple; text-decoration: underline; ">esp-r-bounces@lists.strath.ac.uk</a><span class="Apple-converted-space"> </span>[<a href="mailto:esp-r-bounces@lists.strath.ac.uk" style="color: purple; text-decoration: underline; ">mailto:esp-r-bounces@lists.strath.ac.uk</a>]<span class="Apple-converted-space"> </span><b>Im Auftrag von<span class="Apple-converted-space"> </span></b>Arianna Sdei<br><b>Gesendet:</b><span class="Apple-converted-space"> </span>Mittwoch, 10.<span class="Apple-converted-space"> </span></span><span lang="EN-US" style="font-size: 10pt; font-family: Tahoma, sans-serif; ">September 2014 16:59<br><b>An:</b><span class="Apple-converted-space"> </span></span><span lang="DE" style="font-size: 10pt; font-family: Tahoma, sans-serif; "><a href="mailto:esp-r@lists.strath.ac.uk" style="color: purple; text-decoration: underline; "><span lang="EN-US">esp-r@lists.strath.ac.uk</span></a></span><span lang="EN-US" style="font-size: 10pt; font-family: Tahoma, sans-serif; "><span class="Apple-converted-space"> </span>Club<br><b>Betreff:</b><span class="Apple-converted-space"> </span>[esp-r] phase change materials</span><span lang="EN-US"><o:p></o:p></span></div></div></div><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; "><span lang="EN-US"> <o:p></o:p></span></div><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; "><span lang="EN-GB">Dear All,</span><o:p></o:p></div><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; "><span lang="EN-GB"> </span><o:p></o:p></div><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; "><span lang="EN-GB">I am trying to use phase change materials, phase change plasterboard, via the active components.
