Abstract
The simulation method that investigate the energy characteristics and the thermal environment of the duct-type heating, ventilating, air-conditioning (HVAC) system for the whole housing has been developed. For the ventilation, the network calculation model is adopted. The dynamic characteristics of the air-conditioner and the variable air volume control system are considered. As a result, the simulation results show the characteristics corresponding to the measurement value. The annual performance factor of the HVAC system is higher than the average COP of the air-conditioner by about 20%.
