Re: [TRNSYS-users] Water-Water heat pump power consumption



Roberto,
 I seem to remember that 4 or 5 years ago there was a bug in Type668 that didn't correctly switch the power use off. What version of the TESSLibs do you have? It might be a good idea to make sure you have the latest version from your distributor.
Best,
 David

Hello all,

I´m working in a full-water HVAC system with a heat pump (type668) as heat source and i´m getting results that seem ilogical:
When no actuator is working, the resulting power consumption of the heat pump is different than 0.
The power consumtion remains the same as the one in the last instant when it was turned ON.

Does anyone know the reason for this?
I have checked my proyect and the source code of the involved type 668 and haven´t found a solution. So any help would be appreciated.

Thanks in advance.
