Dear Peter,
die Types 361 und 362 are non-standard types from Transsolar

Hi Juan!
Thank you for the anwser.
Are TYPE 361 and TYPE 362 radiators ?
I can't seem to find TYPE 361 and TYPE 362, are they part of the TRNSYS/TESS library and if so, under which directory are they?
If they are not part of TRNSYS/TESS library then where can you get them?
Best regards
Peter

Hello Peter.
As another option, you may use the nonstandard Types from Transsolar, TYPE 361 and TYPE362, which include static (steady state) and dynamic (considering the
heat capacity of the radiator) models.

Hi !
I am simulating the heating of a house with the help of a solar thermal system in TRNSYS. Previously I used a radiator Type1231 for heating the house, the problem is that I discovered that the water flowing out from the radiator had a temperature lower than
that of the ambient temperature of the house, and sometimes would drop as low as below freezing.
This would meen that the radiator is extracting energy from the water rather than just letting the hot water radiating heat, and thus not simulating a real radiator in an accurate way.
Now I am using the heat exchanger Type5c instead and trying to let it work as a radiator by letting the influid have the specific heat 4.19 kJ/kg*K (water) and the outfluid 1 kJ/kg*K (air). This seems to work reasonably well the problem is that it is hard to
know how large the flowrate should be on the load side to simulate a real radiator in an accurate way.
I have been thinking about maybe using an equation instead, but the same problems with uncertainty regarding how large the flowrate on the load side should be would occur there.
Does anyone know if there is a way to let the radiator Type1231 work properly, or does anyone have any other ide of how to simulate an ordinary radiator with water inflow radiating heat (heating) the air around it?
