[Equest-users] VRV output

Without looking at your model, my assumption would be that the
consumption is as a result of the compressor crank-case heater.
 
I would suggest running an hourly report to verify...

Hi,

Really appreciate if someone can explain this anomaly or lack of my
knowledge.

I'm simulating a VRV system using PVVT system type (heat pump) according
to some suggestions posted on bldg-sim. I notice that whenever the fans
are off the electric input to both heating and cooling show 25 watts for
each hour throughout the year. How can a heat pump consume electricity
for both heating and cooling when fans are off?
Would it be realistic to ignore 25 watts for all the hours fans are off?

Thanks much.
