[Trace-users] Problems with the Simulation of an Air-Water Heat Pump

Fri Aug 13 04:25:17 PDT 2010

Ricardo,

Your attachments did not come through but I can get them from the
archives. Is this a water source heat pump cooling air or a air source
heat pump cooling water?

Greetings,

My name is Ricardo Lic?nio Marques. I work in a thermal consulting
company, Protermia Lda. My version of the software is 6.2.5.1

I would like some clarification on a problem I?m having when simulating
the use of an Air-Water Heat-Pump. Initially, I introduced a water-water
Heat Pump ( Default Water Source HP) with a thermal storage with the
option ?none? and a Heat Rejection with the option ?Condenser Fan for
Heat Pump?.
With these definitions selected, the results of the simulation in Energy
Consumption report Summary came back blank, without any value.

To resolve this problem I?ve changed some definitions of the heat pump I
had created. When I ran the simulation, after these changes, the energy
report summary started displaying results without any problems. The
modifications made are as it follows: In the library editor, cooling
equipment, selecting the heat pump I?ve created, in the ?Unloading
curves option?Ambient modification? I changed ?Wshphi  - Amb Mod? to
?Air to Air Heat Pump - Amb Mod? in primary and ?Wshphi - Amb Mod 2nd?
to ?Air to Air Heat Pump - Amb Mod 2nd? in secondary. The thermal
storage stayed with option ?none? and Heat Rejection with the option
?Condenser Fan for Heat Pump?.

I would like to know if this is the right way to define an Air-Water
Heat Pump also, if there is another way to solve this problem. In
attachment I?m sending two TAF files, one before the changes and one
after the changes. I find it hard to believe that these simple
modifications could have made/cause the difference/problems in the way
the Energy summary reports are presented.

Best Regards,

Ricardo Marques
