HVAC (Heating, Ventilation and Air conditioning) System
HVAC (Heating, Ventilation, and Air Conditioning) is a system that provides heating and cooling. This system uses fresh air from outside to provide high-quality indoor air (oxygen) that is free from smoke, odor, heat, dust, airborne bacteria, carbon dioxide, and other gases at a suitable temperature. This technology will create thermal comfort and acceptable indoor air quality (by room occupants).
