[TRNSYS-users] TRNSYS-users Digest, Vol 89, Issue 19

Fri May 11 01:26:35 PDT 2012

Hello Dakhli,

very briefly:
You need a table of operation points from your machine. It must consist 
of values for
- Fraction of design load 
(=FLOW_CHW(i)*CP_CHW(i)*(TCHW_IN(i)-TCHW_SET(i))/DesignCapacity)
- Chilled water setpoint
- Entering Chilled Water Temperature
- Inlet Hot Water Temperature
covering the range you want to simulate.
Additionally, you need to calculate the two values for these operation 
points TRNSYS will receive from the performance map:
Fraction of rated capacity (=Capacity(i)/DesignCapacity)
Fract. Of Design Energy Input (=Q_Hot_Water(i)*Design_COP/DesignCapacity)

All values with an "(i)" are values specific for that single operation 
point.

You can have a look at the source code of the type, there it all 
becomes... clear.

Imho, this type is unessecarly complicated and the map is tricky to set 
up. Have a look at the documentation and the source code and If you need 
further assistance, let me know.

Best regards,
Jochen
