Hi Richard
It is possible to use up to 4 independent (inputs) and 5 dependent (outputs) in each dynamic data interpolation. (TRNSYS manual, page 7-64)
To describe the order it is an example of a case with two inputs and one output:
1 2 3 (a, first independent input)
6 7 8 (b, second independent input)
100 (value of c when a=1 and b=6)
200 (value of c when a=1 and b=7)
300 (value of c when a=1 and b=8)
400 (value of c when a=2 and b=6)
500 (value of c when a=2 and b=7)
600 (value of c when a=2 and b=8)
700 (value of c when a=3 and b=6)
800 (value of c when a=3 and b=7)
900 (value of c when a=3 and b=8)
It is all you need to develop a data file.
Note:
Bear in mind that when you are writing a code with Fortran, the order of independents (inputs) should be written reversely. In the other words, in Fortran code 'b' should be considered as the first independent parameter.
Disregards this note if you just want to modify a data file or develop a new data file. The note is useful when you want to write a code for a new component.
For more detail refer to page 7-66 TRNSYS manual.
Hope it helps

Subject: SV: [TRNSYS-users] Question about external files for type 927
Hello!
No I haven?t solved
it yet. I have looked in the example file and can see that the first row is load
flow, the second row is source flow, the third row is load EWT and the fourth
row is source EWT but I don?t know if this data on the rows are in some special
order or if I need values for the whole capacity range of the heat pump. After
the first four rows there are rows for capacity ratio and power ratio but I
don?t know how many rows is to be input and if they should be in some special
order.
It?s probably not so
difficult but I don?t seem to solve this myself.
Best
regards

external files for type 927
Hi Trnsys users.
I?m new to Trnsys and have a problem with
creating an external heating file for the type 927.
I have looked in the manual chapter 7,
7.4.4.4. DynamicData (DYNDATA and DATA) but I still don?t get
it.
Exactly how is the file created? I have
capacity test data for the heat pump according to EN255 and EN14511 in the form
of load and source temperatures and flows and the electrical power and
heating.
Best regards.
