  • Pressure controlled fresh air supply ventilation system using soil gas pressure as a reference, and method of use
    Patent number: 5131887
    Abstract: A ventilation system allows for a user adjustable minimum inlet fresh air volume inflow rate, a user adjustable minimum exhaust air volume outflow rate, for an enclosed space, and provides for automatic adjustment of the air volume flow rate(s) to maintain the air pressure inside the enclosed space at a user selected level which is measured in relation to the relatively constant soil gas pressure beneath the enclosed space, or pressure under the floor of the lowest occupied level, under which floor, soil gas is present.
