An intense field dielectric air filtration system includes a perimeter frame for wall or ceiling mounting at the inlet of a return air duct for an air conditioning apparatus. A door including a grille disposed thereon is mounted for movement on the frame between working and non-working positions for access to an air filter unit, a pre-filter unit and an intense field particle charging unit. Contacts on the filter unit and the field charging unit engage cooperating contacts on an enclosure mounted on the frame when the door is closed to supply electrical power. An interlock is provided to interrupt power when the door is moved to an open position or the grille is removed. A control system disposed in the enclosure includes user control features accessible when the door is in an open position. An alternate embodiment includes a support frame for positioning the filtration system in ductwork or the like other than a return air inlet.

Air filtration system

An air conditioning apparatus includes a cabinet having air inlet and outlet openings and an intense field dielectric air filtration system disposed in the cabinet between the inlet and outlet openings. The filtration system includes a field charging unit and a filter unit. The filter unit may be mounted for removal from the cabinet on spaced apart support brackets connected to the cabinet or to a frame of the field charging unit. Electrical contact elements may be supported by the support brackets for engagement with corresponding contact elements on the filter unit and charging unit for establishing electrical communication between a power supply and the charging unit and filter unit, respectively. A shorting bar is aligned with the contact members on the filter unit for discharging high voltage potential upon removal of the filter unit from the cabinet.

Air conditioning apparatus with integrated air filtration system

An air filtration system includable in and for HVAC equipment includes one or more intense field dielectric filter units and a field charging unit retained in a support structure or cabinet by a removable door which includes control circuitry and contactors engageable with corresponding contact members on a filter unit and the field charging unit for supplying high voltage DC potential to the respective units. Each filter unit includes a filter core comprising a stacked array of filter elements formed of dielectric sheets interconnected by elongated spaced apart ribs forming flow passages. The field charging unit and the filter units are removable from the support or cabinet for cleaning or replacement by opening or removing the door. An interlock switch and a field shorting mechanism are actuated during servicing or replacement of the system components.

A humidifier () is disclosed having a top portion (), a middle portion () and a bottom portion (). The middle portion is essentially a water tank which provides water to be used in humidification. The bottom portion has a floor () and side walls () extending from the floor to form a tub () having a select height (SH). The bottom portion is configured so that should water be uncontrollably released from the middle portion, the water level within the middle portion (MPEWL) will reach an equilibrium level with the catastrophic water lever (CEWL) within the bottom portion below the selected height of the bottom portion (SH). When the middle portion water lever (MPEWL) reaches the same height or equilibrium lever with the bottom portion catastrophic water lever (CEWL) the flow of water from the middle portion will cease. As this equilibrium level is below the select height of the bottom portion (SH) the water will be fully captured and will not overflow onto the underlying floor.

An air purifier ( ) is provided having a housing ( ) having a grilled air inlet ( ), a grilled air outlet ( ), and a control panel ( ). The air purifier ( ) also includes a pre-filter ( ), a main filter ( ), a blower ( ) and a controller ( ), all mounted within the housing ( ). The controller ( ) has a central processing unit having a permanent memory for storing the program instructions for operation and control of the air purifier, a working memory, and a non-volatile memory for the permanent storage of programs and counters. The controller is programmable so as to control the operation of the blower according to time and speed parameters entered into memory.

A remote control receiver is provided, as well as a system for installing the receiver within a motor housing of a ceiling fan which may comprise a low profile ceiling fan. The receiver may be provided as an add-on unit or pre-packaged with new fans. The receiver includes upper and lower housings which engage one another and define an interior space of the receiver. Electronic circuitry is provided within the interior space which is effective for controlling at least the rotational speed of the ceiling fan motor and the fan blades attached to the motor. The receiver may optionally control the operation of a light fixture included as part of the fan, and in some applications the receiver may also control the direction of rotation of the motor and blades. The system for installing the receiver within the motor housing includes a stationary portion of the ceiling fan, such as a ceiling mount plate or motor mount plate, which is spaced apart from the rotating components. The system may farther include a plurality of apertures formed in the lower housing of the receiver and at least one strap, wire or cable, etc. which is passed through selected ones of the apertures and attaches the receiver to the stationary portion of the fan. Alternatively, the receiver may be disposed within a mount pocket formed by a bracket attached to a stationary portion of the fan such as the ceiling mount plate.

A microprocessor-controlled electronic thermostat system and method that detects the status of a thermostat output relay to determine if the relay has been set to a state as requested by the microprocessor and, if not, providing a boosted or increased voltage to the output relay in an attempt to correct the relay setting. Preferably, the system determines if the output relay is correctly turned off as requested by the microprocessor, and, if it is not, a first boosted voltage value is provided to the output relay in an attempt to turn the relay off. If this fails, a second higher boosted voltage value is provided to turn the output relay off. This continues periodically until an off condition is detected.

Voltage boosting system and method for electronic thermostat relay

An electronic programmable thermostat having a program set made up of a plurality of program start times and program temperature values for a daily time period which can be automatically vacated upon initiation by the thermostat user. The user may initiate a temporary reset of the program time/temperature values whereby a microprocessor sets a new temperature value corresponding to a comfort temperature value obtained from one of the program temperature values. Preferably, the system automatically sets a temperature value equal to the highest temperature value of the program set temperatures, when in a heating mode, or the lowest temperature value when in a cooling mode. The system maintains such reset values until the beginning of one of the program start times depending upon when the reset feature was selected by the user.
