Because of this, there may be instances throughout the year where the minimum required cooling air over cools the space, leading to discomfort for the occupants. These systems are used for cooling purposes in applications having a year-round cooling load. The diagram below shows all the sound paths from a terminal unit and how they reach the occupant. • Requires the use of diffusers with proven distribution characteristics over a wide range of air flows. This is tested at certain airflow points in a reverberation room with connected ductwork routed outside the room, this is an effort to just pick up the sound that is radiated from the casing. A wide range of models, accessories, and options are available. 5 gpm of 180° F water flow would generate ~4, 250 btu/hr of heat. This is more than enough to heat the space. Buildings with a central corridor and rooms with exterior exposures located on both sides of the corridor (double loaded corridors) are usually not good applications for variable air volume. I chose to enter the required leaving air temperature (LAT) and it chose a 1 row coil with. However, not every room in a zone has the same desired set point.

Thanks for your input. Each room can have its own air volume controller, making it possible for every room supplied by the air handler to have independent temperature control even though the temperature leaving the air handling unit does not change.
