  • Circulating air scrubber
    Patent number: 4846856
    Abstract: An ultrasonic circulating air brush scrubber with a supply of scrubbing liquid in finely dispersed form in the intake air stream, and a high-voltage ionizer, includes at least one circular brush downstream of the ionizer. The brush is driven at high speed and is at the opposite potential from the ionized air stream. The circulating air scrubber provides a high degree of cleaning action for particle sizes down to below 1 .mu.m., low consumption of scrubbing liquid and dries the air on the output side.

  • Air purification electrostatic charcoal filter and method
    Patent number: 4244710
    Abstract: An air purification filter is provided which has a housing; an inlet in the housing for air to be purified; a microporous filter medium, activated charcoal, which is placed in the housing so that the air to be purified passes through this microporous filter medium. The microporous filter medium serves as an electrostatic filter, with the air, including the particulate matter in the air, being charged to one polarity just prior to reaching the microporous filter medium, and with the microporous filter medium itself being directly charged, with an electrode at the downstream surface of the microporous filter medium. In a preferred embodiment an odor neutralizing medium bearing a charge opposite to that of the microporous filter medium is placed upstream of the microporous filter medium.

  • Apparatus to transfer heat or refrigerant
    Patent number: 4143523
    Abstract: The invention relates to an apparatus for the transfer of heat or refrigerant between two separate flows of fluid, by means of a heat pump incorporating a refrigeration cycle. The refrigeration apparatus comprises an evaporator, a compressor, a condenser and a regulating valve, the evaporator and the condenser being adapted for heat exchange with the two separate fluid flows. During a heating operation, one of the fluid flows, before entering the evaporator, is brought into heat exchange in a first heat exchanger with the refrigeration cycle between the condenser and the regulating valve.
