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,

Hi,

I want to model actual installation of the system in picture 1 in TRNSYS and my cycle is in photo number 2. i think in TRNSYS instead of the cycle i should use the geothermal heat pump (water to water or water to air), I want to use this cycle that I modeling and I want to compare the Experimental results and the theory results, please help me in modeling the cycle in TRNSYS.

As you know, the geothermal heat pump needs a catalog and performance data for the simulation to be defined as an input to this component (total, sensible, power). How can I determine these values form an Experimental project(picture 1)?

Is the third image attached to email simulated this cycle properly in the TRNSYS software base on picture 1 and my cycle?

Thanks a lot
