  • Railroad car is one of major public transportation because of an increase in population and heavy traffic problems. We design the concept with air filtration of HVAC system using CFD, select environment-friendly components and compose intellectual HVAC system. For this object, the research to connect HVAC system which control temperature, humidity, air flow with pollutant controlling system which can deal with particular dust, nasty smell. In case of train, fresh air should be provided continuously for pleasant environment of the cabin every season. The air will control outer dust, inner particular dust, $CO_2$ density by air conditioning, heating, humidity regulating, air filtering and ventilating. Ventilation system on passenger cars should be designed for the health and comfort of the passengers.

  • The major goal of building energy management is to minimize the energy consumption while maintaining the comfortable environment condition. Nowadays building energy management to save HVAC energy and so on is the most critical issue for existing building service branch with high efficiency equipments and their optimal operation. The effects on the building energy savings of the building equipment retrofit and the improvement of its operation method, especially in the field of HVAC system, were analyzed in this study for domestic small and/or medium sized buildings. Over 8.8% of energy saving was achieved compared withe total energy consumption in commercial building. These results could be used for reasonable maintenance and efficient management of the various building service equipments and related systems.
