초록 ▼

An apparatus for ventilating the crawl space of a structure, comprising an exhaust fan in a housing adapted to at least partially occlude an aperture in a foundation wall of a structure and oriented to, upon receiving an appropriate stumulus, exhaust crawl space air through said aperture to outside the structure, a temperature sensor and a relative humidity sensor for sensing the respective temperatures and relative humidities of crawl space air and of outside air, and for transmitting respective stimulus dependent thereon to a programmed computer, said computer also adjusting said relative humidity stimulii for temperature-dependent deviation, then determines the absolute moisture differential from said adjusted stimulii and compares said differential to a pre-set minimum absolute moisture differential parameter for ventilation activation, said computer also functionally connected to said fan for controlling the activation thereof

[ I claim:] [1.] An apparatus for ventilating the crawl space of a structure, comprising:at least one electrically powered means for causing the transport of crawl space air, said air transport means adapted to at least partially occlude an aperture in a foundation wall of the structure and oriented to, upon receiving an appropriate stumulus, cause the transport of crawl space air through said aperture to outside the structure;at least one humidity sensing means for determining the relative humidity of crawl space air and of outside air, respectively, and for transmitting respective stimulus dependent thereon (the "RH stimulus");at least one temperature sensing means for sensing the respective temperature of crawl space air and of outside air, and for transmitting respective stimulus dependent thereon;at least one control means including means for setting and storing at least one pre-set minimum absolute moisture differential parameter for ventilation activation, said control means functionally connected to said humidity sensing means for controlling the activation thereof and receiving RH stimulus therefrom, said control means also functionally connected to said temperature sensing means for controlling the activation thereof and receiving temperature stimulus therefrom, said control means also for adjusting said respective RH stimulus for temperature-dependent deviation and determining therefrom the respective absolute moisture of the crawl space air and of the outside air, said control means also for determining the absolute moisture differential between said respective absolute moistures and comparing said differential to said minimum absolute moisture differential parameter for ventilation activation, said control means also functionally connected to said air transport means for controlling the activation thereof, wherein(a) said control means causes said humidity sensing means and temperature sensing means to sense the respective relative humidities and temperatures of crawl space air and of outside air and to transmit to said control means respective RH stimulus and respective temperature stimulus dependent thereon; whereupon(b) said control means adjusts said respective RH stimulus for temperature-dependent deviation and, for each of said respective adjusted stimulus, determines the respective absolute moisture of the crawl space air and of the outside air; whereupon(c) said control means determines the absolute moisture differential between said respective absolute moistures and compares said differential to said minimum absolute moisture differential parameter; whereupon(d) if said absolute moisture differential is greater than said minimum absolute moisture differential parameter, said control means activates said air transport means to cause the transport of crawl space air outside, causing the influx of drier outside air into the crawl space thereby lowering the humidity therein.
