Abstract
Abstract An apparatus in which air in a room such as sickroom, aseptic working room etc. is fed to an water-spraying cyclone to remove dusts and microbes and make air humid, and fed the resulting air to a temperature-regulating cyclone to remove water droplets and regulate a temperature as required, and then fed thus obtained temperature-regulated air to said room for circulation of the air through this system. Using this microbe-removing and air-conditioning apparatus, it is possible to obtain an air of desired temperature and humidity, and at the same time supply an air from which microbes have been completely removed and which is most appropriate for sickroom, operating room etc.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
180 words
A microbe-removing and air-conditioning apparatus comprising a room; a water-spraying cyclone, in which a return pipe is surrounded with a water pipe which has a plurality of spraying nozzles, said water-spraying cyclone comprising means through which the air in said room is circulated and in which water is sprayed and odor, fine dust and microbes are caused to adhere to the wall of the cyclone and removed, and the air is caused to become saturated with moisture; a temperature-regulating cyclone in which a temperature-regulating medium conduit is spirally arranged within said cyclone, said temperature-regulating cyclone comprising means to remove water droplets from the humid air pressing from said water-spraying cyclone and means to regulate the temperature of the air; and a circulation pipe for feeding the air leaving the room to the water-spraying cyclone and from the water-spraying cyclone to the temperature-regulating cyclone and then back to the room therefrom; wherein upstream the water-spraying cyclone there is provided a sterilization cyclone where a high temperature vapour is introduced and mixed with the air coming from the room to effect sterilization.
Claim 2
Dependent Claim
180 words
A microbe-removing and air-conditioning apparatus comprising a room; a water-spraying cyclone, in which a return pipe is surrounded with a water pipe which has a plurality of spraying nozzles, said water-spraying cyclone comprising means through which the air in said room is circulated and in which water is sprayed and odor, fine dust and microbes are caused to adhere to the wall of the cyclone and removed, and the air is caused to become saturated with moisture; a temperature-regulating cyclone in which a temperature-regulating medium conduit is spirally arranged within said cyclone, said temperature-regulating cyclone comprising means to remove water droplets from the humid air pressing from said water-spraying cyclone and means to regulate the temperature of the air; and a circulation pipe for feeding the air leaving the room to the water-spraying cyclone and from the water-spraying cyclone to the temperature-regulating cyclone and then back to the room therefrom; wherein upstream the water-spraying cyclone there is provided a sterilization cyclone where a high temperature vapour is introduced and mixed with the air coming from the room to effect sterilization.
Claim 3
Dependent Claim
251 words
A microbe-removing and air conditioning apparatus comprising a room; a water-spraying cyclone, in which a return pipe is surrounded with a water pipe which has a plurality of spraying nozzles, said water-spraying cyclone comprising means through which the air in said room is circulated and in which water is sprayed and odor, fine dust and microbes are caused to adhere to the wall of the cyclone and removed, and the air is caused to become saturated with moisture; a temperature-regulating cyclone in which a temperature-regulating medium conduit is spirally arranged within said cyclone, said temperature-regulating cyclone comprising means to remove water droplets from the humid air pressing from said water-spraying cyclone, and means to regulate the temperature of the air; and a circulation pipe for feeding the air leaving the room to the water-spraying cyclone and from the water-spraying cyclone to the temperature-regulating cyclone and then back to the room therefrom; said water-spraying cyclone comprising an elongated vertically disposed cylindrical chamber, the axial length of which is substantially greater than the diameter thereof, said return pipe and said water pipe passing axially into said elongated chamber through the top thereof and extending to near the bottom thereof, said plurality of spraying nozzles being disposed along substantially the entire length of said water pipe and being disposed about the circumference thereof, and said circulation pipe for feeding air to the water-spraying cyclone having an exit end substantially tangent to the cylindrical said wall of and near the top of said cylindrical chamber.
