Corona-discharge air mover and purifier for packaged terminal and room air conditioners
View Patent ↗An air conditioning device for heating and/or an environment is provided. The air conditioning device includes a heat exchanging apparatus, a passage, and a corona discharge apparatus. The passage is in thermal communication with the heat exchanging apparatus and extends between an inlet and an outlet. The corona discharge apparatus is disposed within the passage to draw a fluid from the environment into the passage through the inlet, move the fluid through the passage to permit the heat exchanger to remove or heat the fluid, and expel the fluid through the outlet into the environment. As such, the environment is cooled or heated. Embodiments of the present invention include package terminal air conditioners (PTACs), room air conditioners (RACs), and mini-split heating and cooling systems.
1. An air conditioning device for heating and/or cooling an environment, comprising:
a housing having a passage extending therethrough between an inlet and an outlet
a heat exchanging apparatus in thermal communication with the passage; and
a corona discharge apparatus positioned in relation to the passage such that when operated air from the environment is drawn into the passage through the inlet, moved through the passage, the corona discharge apparatus being the sole means for drawing the air into and through the passage, wherein a heat exchange with the heat exchanging apparatus takes place, and expelled through the outlet into the environment.
2. The air conditioning device of claim 1 , further comprising a high-voltage power supply coupled to the corona discharge apparatus.
3. The air conditioning device of claim 2 , further comprising at least one control component operatively coupled to the high-voltage power supply to vary an output voltage thereof.
4. The air conditioning device of claim 1 , wherein the heat exchanging apparatus includes at least one heat exchanger coil positioned within the passage.
5. The air conditioning device of claim 1 , wherein the heat exchanging apparatus is a phase change heat pump having at least one heat exchanger positioned within the passage.
6. The air conditioning device of claim 1 , wherein the corona discharge apparatus includes at least one negatively charged plate removably positioned in the passage to permit at least one of inspection, cleaning, and replacement.
7. The air conditioning device of claim 1 , wherein the corona discharge apparatus includes negatively charged plates configured to remove contaminants from the air in the passage.
8. The air conditioning device of claim 1 , further comprising:
a variable high-voltage power supply coupled to the corona discharge apparatus; and
a control component operatively coupled to the high-voltage power supply to vary an output voltage thereof between at least two discrete voltages such that the corona discharge apparatus is operative to move air through the passage at at least two discrete speeds.
9. The air conditioning device of claim 1 , further comprising:
a variable high-voltage power supply coupled to the corona discharge apparatus; and
a control component operatively coupled to the high-voltage power supply to vary an output voltage thereof over a continuous range of voltages such that the corona discharge apparatus is operative to move air through the passage at different speeds.
10. The air conditioning device of claim 1 , wherein the corona discharge apparatus comprises a positively charged emitter array in spaced relation to a negatively charged collector array, the emitter array producing positively charge ions that are attracted to the negatively charged collector array.
11. The air conditioning device of claim 1 , wherein the cooling device further comprises an ozone depletion apparatus positioned downstream of the corona discharge apparatus.
12. An air conditioner for cooling an environment, the air conditioner comprising:
a heat exchanging apparatus configured to absorb heat;
a passage operably coupled to the heat exchanging apparatus, the passage extending between an inlet and an outlet;
a positively charged emitter array in the passage; and
a negatively charged collector array in the passage and in spaced relation to the positively charged emitter array, the positively charged emitter array and the negatively charged collector array cooperatively producing an electric wind in the passageway such that a fluid is drawn from the environment into the passage through the inlet, the fluid is moved through the passage where the heat from the fluid is absorbed by the heat exchanging apparatus to cool the fluid, and the cooled fluid is expelled through the outlet into the environment to cool the environment, the emitter array and collector array being the sole means for drawing the fluid into and through the passage.
13. The air conditioner of claim 12 , wherein the heat exchanging apparatus is operative to dehumidify the fluid flowing through the passage.
14. The air conditioner of claim 12 , further comprising a voltage source to provide a positive charge to the positively charged emitter array and a negative charge to the negatively charged collector array.
15. The air conditioner of claim 14 , further comprising at least one control component operatively coupled to the voltage source to vary the positive and negative charge provided thereby to vary a speed of the electric wind.
16. The air conditioner of claim 12 , wherein the heat exchanging apparatus comprises a hot side and a cold side, and wherein the hot side is positioned outside of the environment and wherein the cold side is positioned inside of the environment.
17. The air conditioner of claim 12 , wherein the negatively charged collector array is configured as removable plates to permit at least one of inspection, cleaning, and replacement thereof.
18. The air conditioner of claim 12 , further comprising an ozone depletion apparatus positioned in fluid communication with the passage.
19. The air conditioner of claim 18 , wherein the ozone depletion apparatus is positioned in the passage downstream of at least one of the positively charged emitter array and the negatively charged collector array.
20. The air conditioner of claim 18 , wherein the ozone depletion apparatus is positioned in proximity to the outlet.
