Hello all, I am resending the attached message as it appears not to get through the system on my earlier attempt. I will appreciate your help. Regards Abdullahi -----Original Message----- From: Ahmed Abdullahi Sent: 30 April 2007 16:59 To: 'trnsys-users@engr.wisc.edu' Subject: Hypocaust Type460 Hello all, I am trying to use Type460 to model earth to air heat exchanger. I am not sure how best to specify the input Tsurf/Qsurf. I have tried to do that by using Type 109 TMY2. When I run a simulation using the supplied parameter definition files, the outlet temperature I am getting is the same as ambient temperature (inlet temperature) that tells me something is wrong with my simulation (I suspect the problem is with the Input Tsurf/Qsurf, but not sure). I attach here my project file and parameter def & control files; I will appreciate any suggestions on how to get the project to give me some reasonable results or how best to specify the input Tsurf/Qsurf for different surfaces.
