Re: [TRNSYS-users] Fuel cell CHP

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

Laura,

 It is a bit hard to answer your question because "CHP" covers a very great number of possible technology combinations. One possibility is that you are producing electricity with a fuel cell and recuperating heat from the fuel cell for some other purpose. The PEM fuel cell model gives you an estimate of various heat flows (heat flow into the cooling water, heat loss to ambient, required aux heat, etc.) Those heat flows can be the inputs to other parts of the CHP system by imposing them on liquid flows either using an equation or using components from the TESS Loads and Structures library (have a look at Type682). Can you be more specific about the shortcomings that you see? It would help a lot in giving a more direct answer.

kind regards,

 David

Hello everyone,

 

I would like to simulate in TRNSYS a fuel cell cogeneration (CHP) system for a residential building.

I do not find a type in the Cogeneration TESS library that simulate this kind of equipment. And I am not sure that the Fuel cell types in the Hydrogen systems library can be used for a cogeneration system.

 

I have already used type 907 (IC engine cogeneration) in the past and I am wondering if it makes sense to use data from the fuel cell CHP in the type 907 (external file).

Do you have other suggestions ?

 

Thank you,

Laura
