[TRNSYS-users] Heat Storage: Type 340

[Mahach, Hassan]

Hi everyone,

I'm Simulating a Heat pump (TYPE 401) connected to a heat exchanger which is immersed in a heat storage (please see picture enclosed). After some time, the simulation stop because of the following error :

"water in the store is ice at I: 56 J:2 T:-0.2..."

And this could be because of the outlet temperature of the evaporator (the input to the HX immersed in the Heat storage)  which may be lower than 0


I'm simulation the heat storage with Type 340, and I change the thermal properties of the fluid in the storage so I can assume that I have water mixed with antifreeze but also the same error.

My question is : is Type 340 just for water or we can we use any kind of fluid?

Have anyone an answer for this question or an idea to solve this problem?

Thank for your cooperation
Hassan
