[TRNSYS-users] Fw: RE: Help me please (TRNSYS)

[David BRADLEY]

Is the heat pump a constant compressor speed device or does it have a 
variable speed compressor?

If it is a constant speed device then I would recommend that you take 
your experimental data and plot the heat pump power as a function of 
inlet (load) temperature for some ranges of inlet source temperature. Do 
the same for heat pump capacity (by using heat pump power and COP). 
Those plots can then be used to generate the performance data files that 
the heat pump component requires.

kind regards,

  David
