Abstract
An outwardly projecting air purifier comprising a support, a generally cylindrical array of UV lamp assemblies mounted to the support, wherein each the UV lamp assembly comprises a reflector having a generally parabolic inner surface and a UV lamp so mounted to the reflector that the inner surface of the reflector reflects a portion of the ultraviolet radiation emitted by the lamp in an outward, radial, direction is described herein. The air purifier also includes a convex shaped deflector element so mounted to the support that the airflow is deflected by the deflector element and brought near the lamps.
Abstract
An air purifier has a housing, a motor, a fan, a filtering net, and a power plug. The motor and the fan are positioned in the housing. The filtering net is joined to the front of the housing. The power plug includes a rotatable member and a pair of conductive members; the conductive members have ring-shaped portions concentrically arranged in a chamber of the housing, and are electrically connected to the motor; the rotatable member is rotatably received in the chamber, and has a pair of copper strips, which stick out at outer ends for connection with a power socket, and which constantly touch a respective one of the concentric ring-shaped portions from inner ends in the rotation of the rotatable member for adjustment of the position of the air purifier.
Abstract
In an air conditioning system which includes a catalytic air purifier, a control system is provided for sensing the level of predetermined conditions in a space and for responsively modulating the air purification process in a manner which optimizes the process in terms of its effectiveness and its economical use. The conditions that are sensed include the levels of VOC's, CO.sub.2, and biological contaminants, as well as degree of occupancy, relative humidity and air flow. The air purification process is modulated by varying the power to a UV lamp, turning one or more UV lamps on or off, varying the effectiveness of the catalyst, varying the volume or speed of the air flowstream and/or varying the relative humidity in the space.
