Ravi,
 I am not sure what you mean by a loop heat pipe. There is a heat
pipe model available in the TESS HVAC library (Type 689). If you can send
a schematirc of the system that you are trying to model, I might be able
to offer a bit more specific guidance.
Cheers,
 David

Subject: Re: [TRNSYS-users] Effect of outdoor conditions on building load calculation

Chun Kwong,

  From the warnings, it looks to me as though there is a problem

with the input connections between your weather data reader,

radiation processor, and sky temperature model. If you are using a

standard weather file format, I would recommend that you use Type15

instead of the combination of Type89, 16, and 69 to generate the

ambient conditions for your building. If you are using measured data

to drive the building then you will need to use Type9, 16, and 69 (or

possibly Type109 and 69) in which case, please send me your *.tpf,

weather file, *.bui file and any other files I need in order to run

the simulation so that I can find the connection problem.

Regards,

David
