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

[Ricardo Marques]

Greetings,



My name is Ricardo Licínio 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
