However, it is a straight-forward, and I can summerize it. Please make sure that you are using the current version, 17.1.03 of the TESS Libraries. The source code in the ".\Tess Models\SourceCode\Type941.f90", and you can view this in a simple text editor program. This is an excellent way to see how an output such as power is calculated. It has all of the equations in an easy to follow manner in the new f90 code. Also, the "More" buttons in the proforma are also very helpful for information about the specific variables. It is a performance-map based component like most all of the other HVAC heat pump, air conditioner, and chiller component models. There is a performance map for when it is operating in heating mode, and there is a performance map for when it is operating in cooling mode. These performance map external data files are in the "InterpolateData" format (see the 08-ProgrammersGuild.pdf for more information). Like many of the other TESS heat pump components, the capacity and power in the data file (the dependent variables) are normalized, so the user can adjust the total capacity and power in the parameter of that particular component. <o:p></o:p></p><p>If you have any other specific questions, please feel free to contact me or TESS technical support about the TESS Libraries.<o:p></o:p></p><p> <o:p></o:p></p><p>Thank you,<o:p></o:p></p><p> <o:p></o:p></p><p>Matt<o:p></o:p></p><p> <o:p></o:p></p><div><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'> <o:p></o:p></p></div><p>On 2013-03-07 04:42, Zhe Li wrote:<o:p></o:p></p><blockquote style='border:none;border-left:solid #1010FF 1.5pt;padding:0cm 0cm 0cm 4.0pt;margin-left:3.75pt;margin-top:5.0pt;margin-bottom:5.0pt'><div><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>Dear All,<o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'> <o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>Thank you very much for your time. <o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'> <o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>I have recently built a combined air source heat pump and solar thermal system for my PhD research study.
