Abstract
A hybrid humidity control and air purification device and method for hybrid humidity control and air purification. The hybrid device is a single unit capable of humidifying dry environmental air, dehumidifying humid environmental air and removing particulates and contaminants from the air. The device controls the outgoing air to a relative humidity setpoint between 35-50% with negligible particulate matter content. Particulate matter is transferred to water, which may be supplied and flushed by an automatic water pumping system.
Claims8
A method for hybrid humidity control and air purification, comprising:
- surrounding a cyclonic vessel, a cold water bath, a heating chamber, a heat pump including a compressor and a controller by an enclosure, the enclosure having a first air intake port and a first air outlet vent, wherein the cyclonic vessel is in the shape of a vertically oriented truncated cone with a wide portion disposed at an upper end of the truncated cone and a narrow portion disposed at a lower end of the truncated cone;
- receiving environmental air at the first air intake port fluidly connected to a cyclonic vessel, by actuating a first fan located within the first air intake port;
- providing a water stream in the cyclonic vessel, by actuating a first water inlet valve located in the cyclonic vessel and spraying water through a spray ring disposed inside the cyclonic vessel at the top end, said spray ring having a plurality of holes configured to direct the water to the interior sides of the cyclonic vessel;
- spinning the environmental air and water stream by adjusting the motor speed of a motor located within the cyclonic vessel, wherein spinning the environmental air propels particulates in the environmental air into the water stream, thus purifying the air and generating a purified air stream;
- expelling the purified air stream from the cyclonic vessel into a first air tube by actuating a second fan located within a first air output port in the cyclonic vessel;
- receiving the first air tube at a second air intake port;
- fluidly connecting the second air intake port to a first microbubbling filter located in a first temperature controlled cold water bath having a first cold water volume;
- the microbubbling filter separating the purified air stream into microbubbles, the microbubbles evaporating into a first air volume located above the cold water volume;
- controlling the temperature of water within the cold water volume by adjusting the motor speed of a compressor connected to a cooling coil located within the cold water volume, wherein controlling the temperature controls the humidity of the air in the air volume;
- expelling the humidified purified air stream from the first air volume into a cold water bath air tube by actuating a third fan located within a third air output port located within the cold water bath;
- receiving the cold water bath air tube at a heating chamber air intake port located in the sidewall of a heating chamber;
- heating the humidified air stream;
- and expelling the heated humidified air stream into the environment by actuating an exit fan located within the first air outlet vent;
- wherein the controlling is carried out by a controller configured to receive signals
- from sensors located within the enclosure, and actuate the fans, actuate the water valves, adjust the cyclonic vessel motor speed, control the motor speed of the compressor, and control an expansion valve based on the signals received from the sensors.
