[TRNSYS-users] Generating Steam & Comparing Steam vs. Hot Water

[Matt Duffy]

Fred,

Have you considered the steam boilers in the TESS Cogeneration Library,
Type638 and Type639? These components consider the pressure and enthalpy
and call the steam properties subroutine. I can send you more information
if you wish.

Best regards,

Matt Duffy

Hi All,

Is there a boiler component that can generate low pressure steam. I looked at
Type700 and Type659, and both of them can meet the temperature
requirements of
steam, however I don't know if TRNSYS knows that 110C fluid is steam or
pressurized
water. There doesn't appear to be a boiler with a pressure output.

This is for a study comparing steam boilers vs. hot water heaters. Has
anyone ever
made this comparison?

Thanks,

Fred
