However, we have run across some heat pumps like that and so wrote Type927 to handle that case. Type927 is currently available as a non-standard component. It will be part of the TESS Libraries 3.0.<BR>Kind regards,<BR> David<BR><BR><BR>philippe forest wrote:

<P class=EC_MsoNormal><SPAN lang=EN-US><FONT color=#000000>I am using a water-to-water heat pump (type 668) to simulate an existing installation. I have the performance sheet and the capacity data from the manufacturer depend on temperature and the flow at the source and the load. I would like to know if it’s possible to specify the mass flow of the source and load on the Type 668. Do you have any other suggestion to make my way around this problem?</FONT></SPAN></P>
