Dear all,
I am using the “Compressed Gas Storage, Type 164, linked with a liquid piston compressor (a model that I created with FORTRAN).
The simulation consists of compressing air and store it in the reservoir. The outputs of the ‘’Type 164’’ are: Volume of gas in the reservoir, Pressure of the gas in the reservoir, Pressure level and the Vdot_dump.
Initially the ‘’Type 164’’ perform initial time-step manipulations where the number of moles initially in the reservoir are calculated after finding the initial pressure
(P_INI = PLEV_INI (Level of pressure * PMAX * 1E5). And then the PGAS is calculated by calculating the number of moles IN - moles OUT which they are function of VDOT_IN (output of my compressor model)
I want to begin (at first time step) to compress the air from an inlet pressure (that I fix, for ex: 10 bars) to an exit pressure (also that I fix) that is equal to that initial pressure of the reservoir; For that purpose I linked the PGAS (output of the Type 164) to the exit pressure of my compressor (that is an input for my model).
It is not working; (I thought that trnsys will know that at initial time the PGAS = P_INI and then I have an input for my compressor initially at time0); apparently there is something wrong (Maybe PGAS initially is not taking P_INI into consideration and then at this stage PGAS can not be calculated because VDOT_IN is not given).
I need your help.
Thank you in advance.
