Comparison of reproducibility of a real cav system by dynamic simulation HVACSIM+ and TRNSYS

It is necessary to use the dynamic simulation program to evaluate the dynamic characteristic of the HVAC system. Some dynamic system simulation programs have been developed, but researches concerning the reproducibility of the dynamic HVAC system characteristic are not so much until now. In this research, HVACSIM+ developed by NIST, USA, and TRNSYS developed by Wisconsin University solar energy laboratory, USA, is discussed for this purpose. Reproducibility of two programs and possibility to use them to generate the database for Fault Detection and Diagnosis were verified by comparing the simulated results and the actual measurements. Moreover, some findings of convenience of program were obtained by comparing difference of calculation algorithm in two simulation programs.
