Dear TRNSYS users,
I have a txt file that represents cooling load of a building from 0 to 8760 hr (in hr timestep) and it consists of two columns (time,hr & load,kW)
And I'd like to use type 9e to read it in a project that will run only in the summer in 1 min time step.
Therefore, to understand the reading and the interpolating process of type 9e:
I connected type 9e to printer 25c (output 2 of type 9e to printer 25c) and I let the simulation run from 3624 to 3648 (for example) in a 1 hour timestep.
The parameter of type 9e are:
Mode 5
Headers to skip 1
No. of values to read 2
Time interval of data 1 hr
Interpolate or not-1 1 (interpolate)
Multiplication of factor-1 1
Addition factor-1 0
Average or instantaneous value-1 1 (instantaneous)
Interpolate or not-2 1 (interpolate)
Multiplication of factor-2 1
Addition factor-2 0
Average or instantaneous value-2 1 (instantaneous)
However, when I compared the resulted text file with the original (input) load file I found a small difference between them (just the start point was the same value)
hr original type9e
3624 4.08075 4.08075
3625 3.29606 3.68841
3626 2.67251 2.98429
3627 2.11276 2.39263
3628 1.56749 1.84012
3629 1.00987 1.28868
3630 1.97730 1.49358
3631 3.61448 2.79589
3632 6.02759 4.82103
3633 7.45960 6.74359
3634 8.49693 7.97826
3635 9.06962 8.78327
3636 9.21186 9.14074
3637 9.58118 9.39652
3638 10.29610 9.93864
3639 10.89955 10.59782
3640 11.23216 11.06585
3641 11.21300 11.22258
3642 10.30281 10.75791
3643 8.84916 9.57598
3644 7.35176 8.10046
3645 6.42763 6.88970
3646 5.68270 6.05516
3647 4.99971 5.34120
3648 4.34179 4.67075
I changed the mode to 4 but I did not get the same input values as well.
Am I selected the wrong type of 9 or there is something incorrect in the parameters
Please can anyone help me
Kind regards,
Shahen
