Muhammad,
Can you be a bit more specific about what you mean by
"transient state" analysis? Type1271 uses a performance
map lookup method. Its compressor is assumed to vary its
speed to maintain a constant outlet temperature on the
load side. In that the heat pump compressor adjusts to the
present load requirements it does do a transient analysis.
However, if you are looking for a component that uses a
more first principals approach and models the state of the
refrigerant in the heat pumps heat exchangers,
compressors, and expansion valve then I think you would
need to look to a different Type than 1271.
As a side comment, please note that Type1271 is an air
(source) to water (load) heat pump, not an air to air heat
pump.
kind regards,
David

Hi,
I am a new
user to TRNSYS from Ulster University. I would be
working for my PhD studies on the topic of variable
speed air source heat pump . I found this "Type
1271v2" ASHP from TESS library useful for me.
I am
interested in the transient state analysis of the HP.
Is this Type suitable for me or i should use some
other software(like EES or Matlab) for the transient
state analysis?
Best Regards
