[TRNSYS-users] Question about a line in Type941 source code

[Zhe Li]

Dear All,

 

Thank you for your time.

 

I am trying to understand how TRNSYS calculates power output from this
air-water heat pumps (Type941).

 

I am stuck in a line which I don't know what the two terms are standing for?


 

! Determine the dry air mass flow rate

Flow_air = lps_air*3.6*rho_air_dry_in 

 

Could somebody let me know what are the lps_air and rho_air_dry_in standing
for?

 

I hope I did not break TRNSYS source code rule by asking this question. 

 

Thank you for your help in advance.

 

Zhe Li
