Abstract:

A system and method for maintaining environmental stabilization. In one embodiment, the system includes one or more controllers that communicate with air dehumidification units to control the relative humidity and temperature within a controlled facility. In another embodiment, a single vehicle environmental stabilization system includes a single vehicle unit attached to each vehicle to control relative humidity within the interior of the vehicle. In these embodiments, the system provides alert messages for out-of-range conditions and tracks and reports related maintenance status to local and remote users using an electronic network. A method of achieving environmental stabilization includes determining the ambient value of a relative humidity level at a site, determining a set of design parameters for an environmental stabilization system, selecting a preferred combination of design parameters and structural modifications, remotely controlling the system, and collecting vehicle maintenance status, information using a radio frequency identification system having a portal antenna.
