Abstract:
1. A self-contained system for scavenging contaminated air from above the water surface of a swimming pool that is disposed indoors in controlled environmental air and that is defined in part by a first elongated pool edge along the length of one side of the pool and a second elongated pool edge displaced apart from and opposite the first pool edge, the system comprising: a. a fresh air intake; b. an air intake fan having a suction side and a pressure side, the suction side being connected to the fresh air intake; c. a laminar flow diffuser configured to deliver a laminar flow of air and extending along the length of the first pool edge, the laminar flow diffuser defining a plurality of orifices configured to distribute equally on a volumetric basis along the length of the laminar flow diffuser, the air flowing through said orifices; d. a pressure plenum disposed in flow communication between the pressure side of the air intake fan and the orifices of the laminar flow diffuser; e. a collection plenum extending along the length of the second pool edge and disposed in flow communication with the orifices of the laminar flow diffuser; f. an air exhaust fan having a suction side and a pressure side; g. an exhaust duct having one end and an opposite end, the one end connected to the collection plenum and the opposite end connected to the suction side of the air exhaust fan; and h. an external discharge duct having one end and an opposite end, the one end of the external discharge duct connected to the pressure side of the exhaust fan.
