In order to evaluate the air conditioning system
performance in terms of control, comfort and energy
conservation, this paper presents an approach to
modeling automatic control process in a typical
conditioned space of an office building. As airconditioning
system, constant volume single-duct
system is adopted for interior zone and FCU system
for perimeter zone. As for simulation model, we
adopted dynamic calculation model expanded by
state transition method [1]. The changes of indoor
ambient temperature and relative humidity, the PMVs
and the energy consumption are investigated by these
simulations. The comparison was made between
two cases, one is controlled by temperature only and
the other is simultaneously controlled by temperature
and humidity..
