Abstract

An air cleaner having a plurality of spaced apart filters including an electronic filter, as well as other filters and a spray chamber disposed between some of said filters and having spray nozzles adapted to emit cool liquid in a flow path of air through said filters; and refrigeration means for cooling said liquid so as to cool said air to a degree at which a dew point condition exists such that liquid sprayed into the air will collect moisture from the air, thereby drying and also cooling it.

Claims

1. In an air cleaner the combination of:

a housing having first means defining an air flow path therethrough;

second means for forcing air to flow through said housing along said flow path;

said housing having an inlet and an outlet communicating with said flow path;

a liquid spray chamber in said first means;

nozzle means in said chamber for impingement spraying of air passing through said flow path;

a sump below said chamber for containing water;

refrigeration means in said sump for cooling said water in said sump;

pump means for pumping cool water from said sump to said nozzle means;

said spray chamber having an inlet and an outlet;

a first air filter disposed and adapted to pass air at said outlet of said spray chamber;

an electronic air filter in said flow path of said first means;

said electronic air filter adapted to remove fine particles in the micronic range, from air passing through said flow path;

said refrigeration means adapted to cool said water to a degree whereby spray of said cool water washes said air and causes a dew point condition relative to moisture in said air to thereby clean, dry and cool said air before it passes to said outlet of said housing.

2. The invention as defined in claim 1 wherein a precleaning filter is disposed at said inlet of said chamber;

said nozzle means disposed to receive water from said pump and to emit spray in said chamber adjacent said inlet side of said first filter; and

a filter between said sump and said pump for preventing material collected in said water from entering said pump.

3. The invention as defined in claim 1 wherein an activated charcoal filter in said air flow path is disposed and located between said first filter and said outlet of said housing.

4. The invention as defined in claim 1 wherein a heater is disposed for heating said air, said heater being located between said first filter and said outlet of said housing.

5. The invention as defined in claim 1 wherein an activated charcoal filter is disposed in said flow path and a heater is disposed in said flow path for heating air, said heater being located between said first filter and said outlet of said housing.

6. The invention as defined in claim 1 wherein a water makeup delivery valve is disposed to deliver water to said sump and a float operably connected to said valve to open and admit water to said sump when the water level therein reaches a predetermined minimum level;

and an overflow means disposed to allow drainage of water from said sump when the level of water reaches a predetermined maximum.

7. In an air cleaner the combination of:

a housing having first means defining an air flow path therethrough;

second means for forcing air to flow through said housing along said flow path;

said housing having an inlet and an outlet communicating with said flow path;

a liquid spray chamber in said first means;

nozzle means in said chamber for impingement spraying of air passing through said flow path;

a sump below said chamber for containing water;

refrigeration means in said sump for cooling said water therein;

pump means for pumping cool water from said sump to said nozzle means;

said spray chamber having an inlet and an outlet;

first and second air filters disposed and adapted to pass air at said inlet and outlet respectively of said spray chamber;

an electronic air filter in said flow path of said first means, said electronic air filter located between said first air filter and said outlet of said housing;

said refrigeration means adapted to cool said water to a degree whereby spray of said cool water washes foreign matter from said air and causes a dew point condition relative to moisture in said air to thereby clean, dry and cool said air before it passes through said electronic air filter and to said outlet of said housing.

8. The invention as defined in claim 1 wherein a precleaning filter is disposed at said inlet of said housing;

said electronic air filter being disposed between said precleaning filter and said spray chamber;

a heating means disposed in said flow path between said first filter and said outlet of said housing for heating air after it has passed through spray chamber; and

an activated charcoal filter in said flow path of said housing.
