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.
Claims2
A hybrid humidity control and air purification device, comprising:
- a cyclonic vessel having a controllable motor, 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;
- a cold water bath including
- a first cold water bath containing a first volume of water, a first microbubbling filter and a first cooling coil immersed in the first volume of water, and a first volume of air;
- a second cold water bath, wherein the second cold water bath includes a first chamber including a second cooling coil and a phase change material, wherein the phase change material is at least one of paraffin wax of 14 carbon atoms, paraffin wax of 15 carbon atoms, formic acid, peanut oil, or a mixture of tetradecane and hexadecane;
- and a second chamber, the second chamber containing a second volume of water, a second microbubbling filter, and a second volume of air;
- a heating coil,
- an expansion valve located between the second cooling coil and the heating coil, wherein the second cooling coil is immersed in the phase change material and wherein the heating coil is located in a heating chamber;
- a water level controlling system including controllable water inlet and water outlet valves in each of the cyclonic vessel, the first cold water bath, and the second chamber;
- a water pumping system to flush water from the cyclonic vessel, the first cold water bath, and the second chamber;
- an air moving system which includes:
- air intake ports and air output ports located within an enclosure, the cyclonic vessel, the first cold water bath and the second chamber;
- the air intake and air output ports including fans;
- first air tubing connected between an air output port of the cyclonic vessel and an air input port of the first cold water bath;
- second air tubing connected between the air input port of the first cold water bath and the first microbubbling filter;
- third air tubing connected between an air output port of the first cold water bath and an air intake port of the first chamber;
- fourth air tubing connected between the first chamber and a first end of a cooling loop;
- fifth air tubing connected between a second end of the cooling loop and the second microbubbling filter;
- sixth air tubing connected between an air output port of the second chamber and an air intake port of the heating chamber;
- seventh air tubing connected between the air intake port of the heating chamber and a support bracket within the heating chamber;
- a first set of sensors for measuring particulate matter, relative humidity and temperature of the air in the enclosure;
- a second set of sensors for measuring the water level in the cyclonic vessel, and a water level, water quality and temperature of the water in the first and second cold water baths;
- a controller having circuitry connected to and configured to control controllable fans, a compressor motor, controllable valves, the cyclonic vessel controllable motor;
- wherein the controller is further connected to and has circuitry configured to receive signals from sensors;
- wherein the controller circuitry is further configured to control a relative humidity, temperature and air quality of the air expelled through an environmental air outlet vent based on the signals received from the sensors.
