Abstract
A method and apparatus for delivering conditioned air to hospital patient rooms or clean rooms which are maintained at a higher or lower pressure level than the adjacent halls. A constant volume delivery duct is provided to counter the constant volume toilet exhaust, and the flow rates in the constant volume ducts are selected to maintain the desired pressure level in the room. The room temperature is maintained by a variable volume system including a variable volume supply duct and a variable volume return duct. Dampers in the variable volume ducts are controlled in unison to control the room temperature as desired while always maintaining equal inflow and outflow in the variable volume system to maintain the pressure level in the room. A specially constructed and partitioned terminal unit provides a terminal for the variable volume supply and return ducts and the constant volume supply duct.
