Claims
- 1. An air washer having an airstream passing therethrough for maintaining a substantially constant dew point temperature to a conditioned space comprising:
- (a) a means to spray water into the airstream as air enters the washer, said spray means comprising an elongated manifold, a plurality of spray tubes, said spray tubes in fluid communication with said manifold,
- (b) a means for chilling the water prior to spraying, said chilling means in fluid communication with one end of said manifold,
- (c) a means for collecting excess water sprayed into the airstream, said collecting means in fluid communication with the opposite end of said manifold,
- (d) a means for pumping water from said collecting means, said pumping means in communication with said collecting means and said manifold,
- (e) a means to control said chilling means, said chilling control means in communication with said chilling means, and
- (f) a means to control said pumping means, said pumping control means in communication with said pumping means,
- whereby water can enter said manifold from said chilling means and said collecting means simultaneously through opposite ends of said manifold and can exit each of said spray tubes at a different temperature.
- 2. The air washer of claim 1 and including temperature regulating means, said temperature regulating means connected to said chilling control means.
- 3. The air washer of claim 1 and including humidity regulating means, said humidity regulating means connected to said pumping control means.
- 4. The air washer of claim 2 wherein said temperature regulating means comprises a thermostat.
- 5. The air washer of claim 3 wherein said humidity regulating means comprises a humidistat.
- 6. The air washer of claim 1 wherein said chilling control means comprises a valve.
- 7. The air washer of claim 1 wherein said pumping control means comprises a valve.
- 8. An air washer comprising:
- (a) means to spray water into the airstream passing therethrough, said spray means comprising an elongated manifold, a plurality of spray tubes, said spray tubes in fluid communication with said manifold,
- (b) means to chill water, said chilling means connected to said manifold at one end thereof,
- (c) means to collect excess spray water, said collecting means in fluid communication with said washer,
- (d) means for pumping water from said collecting means to said spray means, said pumping means in fluid communication with said collecting means and with said manifold at the other end thereof,
- (e) means to control said chilling means, said chilling means control connected to said chilling means,
- (f) means to regulate temperature, said temperature regulating means connected to said chilling control means,
- (g) means to control said pumping means, said pumping control means connected to said pumping means, and
- (h) means to regulate humidity, said humidity regulating means connected to said pumping control means,
- whereby water can enter one end of said manifold from said chilling means and can enter the other end of said manifold from said collecting means simultaneously where it can be sprayed into said airstream at different temperatures through different spray nozzles.
- 9. The air washer of claim 8 comprising damper control means, said damper control means positioned proximate said washer, said damper control means for regulating the amount of outside air received by said air washer.
- 10. A method of maintaining a constant dew point temperature to a conditioned space by controlling an airstream as it exits an air washer by spraying the airstream within the washer with chilled and ambient temperature water directed into opposite ends of a manifold where the water passes through a plurality of spray tubes connected to said manifold comprising the steps of:
- (a) sensing the temperature and humidity of the airstream as it exits the washer,
- (b) regulating the amount of chilled water directed into the manifold in accordance with the temperature of the airstream,
- (c) regulating the amount of ambient temperature water directed into the manifold in accordance with the humidity of the airstream, and
- (d) spraying the airstream with different temperature water from each of the spray tubes.
- 11. The method of claim 10 wherein the step of sensing the temperature and humidity of the airstream comprises sensing the temperature and humidity with a thermostat and humidistat immediately as the airstream exits the washer.
- 12. The method of claim 10 wherein the step of regulating the amount of chilled spray water comprises operating a chilled water control valve.
- 13. The method of claim 10 wherein the step of regulating the ambient temperature spray water comprises the step of operating an ambient temperature water control valve.
- 14. The method of claim 10 and including the step of controlling the outside air/return air ratio received by said air washer.
