Re: [TRNSYS-users] Tank with a heat pump and a heat exchanger

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

Marion,
  The basic idea of TRNSYS is that systems are modeled as groups of components connected to each other according to the user's specifications. In order to model the system that you propose, you would connect the Type534 heat exchanger outlet liquid temperature and flow rate to the Type938 inlet liquid temperature and flow rate. You would also need a controller model so that the heat pump knows when the tank has reached the desired temperature and may turn off. Since this concept is very central to TRNSYS, I would recommend that you look at some of the examples (particularly the solar domestic water heating (SDHW examples) so that you see how components are linked to one another to form a system.
Regards,

Hi everybody, 

I am a new user of TRNsys and I am asking you some help please.

I would like to model a tank with a heat pump and a heat exchanger at the same time. There is a way to do that? Cause in the TESSLibs17 I only found a heat pump water heater and (type 938) a tank with heat exchangers (type 534). Maybe it is possible to couple both or to find an other trick?

Thank you very much!

Regards,

Marion
