Dear
Huseyin,
Thanks for your answer. However, in your
paper, you used an air-to-air heat pump; however, as I have a
radiator in my system, I need to use an air-to-water heat pump
which there is only a single stage type in the TRNSYS TESS
library.
Kind regards
Pouyan
Dear Sardari,
You can use two-stage heat
pump models to create low, nominal and high stages for the
considered heat pump.
We had a publication for a
two stage air source heat pump. Pls. see the shared link
below.

Dear All,
I am
modelling a house heated by radiators using an air-to-water
heat pump. This model is based on user-supplied data files
containing catalogue data for the capacity and power based
on the inlet water temperature and air to the heat pump. As
I understand, for a specific existed heat pump, the system
should be tested for several inlet conditions (for example 5
different temperatures of water and air=25 case) and then
create a new data file including the capacity and power. Am
I correct?
My main
question is that is it possible to consider additional
characteristics of the heat pump in the model such as
variable speed compressor so the system can be worked with a
lower power when less heat is required for the radiators?
Thanks in
advance
Best regards
