Abstract
A studio HVAC system must provide adequate heating, cooling and ventilation, it must operate as quiet as possible (ideally it should be completely silent) and it should not compromise the sound insulation between rooms (silencers are required between ducts supplying air to different rooms, and between the rooms and the HVAC main machine). So keeping cool while remaining quiet in a control room or on-air studio requires sophisticated air handling systems. The mechanical engineer must design a system that is capable of providing 24-hour cooling for technical equipment, accommodating a significant lighting load and providing a comfortable environment for an audience ranging from 50 to 200 persons, all while meeting a noise-criteria (NC) rating of 25 or lower
