[Equest-users] Help - Understanding hot water loop losses in eQUEST

[Bishop, Bill]

Vaughn,
 
See this ASHRAE article about school potable water heating systems:
http://www.ga.wa.gov/Eas/elcca/Reports/Instantaneous%20Water%20Heating%2
0systems%20for%20schools%20-%20ASHRAE%20artic.pdf
Table 2 has UA values for pipe heat losses. Note that the values in the
table are per foot of pipe.
 
Regards,
Bill

eQUEST
 
This may seem like a silly question, please forgive me, I am an eQUEST
beginner. Does anyone know the basis on which you asign a hot water loop
loss? What exactly is a "supply UA" in a btu/h - degree F? Our model is
currently using the number "9" for a supply UA and seems to be working
nicely. 

Thanks All,
