About this file
This drawing package provides control diagrams for the HVAC systems in several poultry rooms and related support spaces at the USDA Agricultural Research Service Beltsville Agricultural Research Center. The diagrams show control sequences for unit ventilators, exhaust fans, variable air volume boxes, and related equipment. Poultry rooms will have one to three exhaust fans, two to four circulation fans, and one unit heater each. Control panels will be provided for each poultry room and will operate independently from the direct digital control system. Interlocks are indicated to coordinate operation of fans and dampers.
