hello users,
i m modelling radiant cooled building with FCU. i m taking air cooled chiller. my set point temperature is 16 degree C for radiant chiller and 10 degree C for FCU chiller. my room set point is 24 degree celsius. i m taking chiller rated capacity as 10 ton for radiant chiller and 5 ton for FCU chiller. by taking all these as input my zone temperature is coming about 23-25 degree C. The load of Radiant Chiller is coming about 40 KW/hr and the load of FCU chiller is coming about 15 KW/hr which is very more than i expect. when i m doing the same thing in Energy Plus then FCU Chiller is coming about 10 KW/hr and Radiant chiller load is coming about 22 KW/hr that is ok.
so, please tell me what to do so that i can get better results.(i m taking occupancy and internal load schedule same in both trnsys and Energy Plus).
Thanks for any help.
