Re: [TRNSYS-users] Type 60c outlet temperature

[David BRADLEY <d.bradley@tess-inc.com>]

Barto,
  It is not really possible to diagnose the problem without looking at the project. I would recommend using an online plotter to look at all of the temperatures and flow rates of all the flows going into and coming out of the tank. If for some reason all of the temperatures in the system are over 60C (including the temperature of the tempering water) then Type953 would not be able to temper the outlet flow. It could also be that you are seeing higher than 60C temperature at the mixing valve when there is no flow through the valve.
  If you are not able to sort out the problem using Type65 as a debugging tool then you should send your project to your distributor so that they can have a look at it.
Kind regards,
 David

Hi ,

I get some strange result i.e I can not find logic in it: I use tank Type 60c only heated by standard solar collector installation. I use the differential controller(monitoring temp.) to limit the tank top temperature to 60C and I'm also using tempering valve Type 953 with diverting and three-wat valves for controling the outlet temp. In the simulation I get temperatures at the outlet of the three-way valve (after mixing) higher than 60C (even 80-90C) how is it possible?

When I model the HX in Type60c with glycol solution I get convergence problems and with water there is no problem...?

Thank you

Regards

Barto
