[TRNSYS-users] Type941 source code

[Zhe Li]

Dear All,

 

Thank you for your time.

 

I am trying to follow the Type941 source code (since there is no
mathematical description available) in order to understand how exactly this
air-source-heat-pump calculates the power output. However, I have a couple
of questions in regarding with it, hope somebody could help me with these:

1.       I have seen that it requires to call Psychrometrics Routine, Moist
Air Properties and Air Properties. Where can I find these property files?
are they standard values and is there any reference for them? 

2.       The component requires to call data from external file containing
'InterpolateData'. This InterpolateData gives friction capacity and power
for a range of air temperature and water temperature, however I am wondering
what will happen when the actual air temperature and/or water temperature is
out of the range (how the calculation is carried out)? Is there any
correlation used for this scenario?  

 

Thank you very much for your help.
