Air Distribution System

Hvac systems are milestones of building mechanical systems that provide thermal comfort for occupants accompanied with indoor air quality.

Air distribution system.

Air is exchanged in all habitable rooms without drafts or bothersome noises at the highest possible efficiency using the cascade distribution principle. If necessary air is heated at the terminal unit. Ahu the purpose of air distribution system is to create the proper combination of temperature humidity and air velocity in the occupied zone of the conditioned room. Variable volume systems provide ventilation and cooling usually through a single duct system.

Primary hvac equipment includes heating equipment ventilation equipment and cooling or air conditioning equipment. We work with engineers contractors and owners to provide high quality engineered products and services. Provide generous plenum chambers in pressure systems for even air distribution metal is cheap fuel and quality loss is more. Since the conditioned air is supplied directly into the occupied space supply air temperatures must be higher than mixing systems usually above 63 f or 17 c to avoid cold draughts at the floor.

By doing so the air quality in the occupied zone is generally superior to that achieved with mixing room air distribution. If not properly designed the air distribution system has the potential to compromise the comfort conditions it was designed. Air distribution corporation adc is a manufacturer s representative serving the commercial hvac markets of new england. Low pressure supply air moves from the air handler or supply air shaft into an underfloor air plenum.

A variation on vav design is the underfloor air distribution system. Air distribution systems contact us. Hvac systems can be classified into central and local systems according to multiple zones location and distribution. The zehnder comfofresh air distribution system brings fresh air to all supply rooms and simultaneously removes moist or contaminated air and odors from extract rooms.

Adjustable diffusers and damper inserts allow for fine adjustment of air. The air distribution system should impose the least possible resistance to air flow in order to provide sufficient drying air and to transport evaporated water away.
