After carefully reading the mathematical description (also related books) of solar thermal system for flat-plate and evacuated-tube collector, I fully understand how the energy output can be predicted from TRNSYS. However, I am struggling to understand how the ASHP Type941 is to predict the power output. It is vital for me to understand how this component works and be able to write into my final PhD thesis. I am wondering if this mathematical description has been released yet? If it is, I will be very grateful if somebody could send me a copy of it. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Sorry, I have asked a similar question before, however, this is so important that I have no choice but keep asking it.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Thank you very much for your help.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Zhe Li<o:p></o:p></p></div><br clear=all> Tá an teachtaireacht seo scanta ó thaobh ábhar agus víreas ag Seirbhís Scanta Ríomhphost de chuid Seirbhísí Faisnéise, ITBÁC agus meastar í a bheith slán. <a href="http://www.dit.ie">http://www.dit.ie</a><br>
