[TRNSYS-users] Fan coil with heat pump

[David BRADLEY]

Dr Bina,

   I would guess that the cause of the error is that the cooling data 
file doesn't have the correct number of data values in it or else that 
it does not exist where it is expected to be found. The file is not 
accessed until it is needed so it makes sense that the error would not 
appear until cooling is required in the building.

In "supply air conditioning" you want to select "external by another 
component" and then select "userdefined" for both the temperature and 
the humidity. Define input variables for each of these. When you save 
your changes in TRNBuild and return to the Studio you will have three 
new inputs (mass flow rate, temperature, and relative humidity) for the 
air that is going into that zone of the building. These will be passed 
from the fan coil model.

kind regards,

  David
