[TRNSYS-users] Help to Heating District with Trnsys16.1 model

[Angel Carrera]

Dear Laura,

Heat exchangers in trnsys can work both for heating and cooling, you don't
have to change the component due to this. Depending on the component you
choose, in psrticular if the hx properties are inputs or parameters, you
will end up with different hydtaulic layouts in your model: you can have
two hx with mixers and diverters on the network side, or just one hx with
the mixers and div on the generator side. I recommend you type 5 or type 91.
About changing the conditions, depends on what vonditions, but remember
that parameters cannot be chaged during a simulation, regsrds
