Apparatus And Methods For Determining Required Vacuum Characteristics Of A Radon Evacuation System

US Patent:
5388444, Feb 14, 1995
Filed:
Oct 6, 1993
Appl. No.:
8/132761
Inventors:
Thomas J. Gerard - Spokane WA
International Classification:
F24F 7007, G01N 1508
US Classification:
73 37
Abstract:
Testing apparatus and methods are described for determining required vacuum characteristics of a radon evacuation system, wherein the radon evacuation system is of a type which utilizes floor vent holes in a basement floor to evacuate radon from beneath the basement floor. The preferred embodiment comprises an elongated vacuum tube extending from a floor vent hole to a variable vacuum test source. Pressure and air velocity measurement devices are positioned to determine actual static pressure and air flow rate within the vacuum tube. To determine the minimum vacuum required at the floor vent hole, the vacuum test source is adjusted to produce the lowest vacuum which will maintain a negative pressure in nearby test holes. The corresponding static pressure and air flow rate are then noted from the measurement devices.
