[TRNSYS-users] type 700 efficiencies

[Pablo Díaz Núñez <p.diazn87@gmail.com>]

Dear trnsys users,

 

I am simulating and studying the behaviour of a central heating system of a residential building with gas boilers. For the boiler I'm using type 700, where combustion and boiler efficiencies are inputs. I need these values as a function of the intlet water temperature and the part load ratio for the model to work and I don't find this data in any boiler catalog. Only partial data like the boiler efficiency at rated power.

 

If somebody had any cataloge with this data I would be very thankful. Or maybe somebody knows any manufacturer who could provide me.

 

I know it's not a doubt or question about trnsys itself, but I'm a bit desperate.

 

Thanks in advance!
