The method includes creating a rounded main air stream spraying irrigating fluid, separating excess liquid from air, heated air and output air to the consumer. Irrigating fluid is sprayed on a circle coaxial to the axis of winding of the main flow with a simultaneous flow of two streams of air in the tangential and vertical directions so that the sprayed liquid is initially between them. Moreover, additional vertical air flow injected into the area bounded by the circumference of the spray. Conclusion conditioned air produced by channel located along the axis of the swirling flow.

The invention relates to means and methods of air-conditioning and can be used to create the necessary air parameters as in the production process, and in residential buildings.

Currently, when the air conditioning is widespread begin to get setup based swirling air flows. The advantage of these units is that when tightening the air flow get turbulent air flow with higher velocity flow of fluid particles and more what I needed air parameters. However, to create the conditions existing methods and facilities in full it is not possible.

For example, in the known method, implemented in the device for humidifying gas (see A. C. of the USSR № 1488684 in class. F 24 F 6/00), a swirling flow is generated due to the tangential entry of the air into the device further movement around the Central vertical duct down and its subsequent release on this duct is designed for unwinding and atomization of the liquid inside of a truncated cone mounted coaxially to the output duct.

The disadvantages of this method and device for its implementation is that the spin liquid atomization and humidification occur due to one of the swirling flow, which does not provide sufficient crushing of fluid particles and does not provide sufficient contact surface between two media. In addition, given the limited area of the air outlet inner surface of the cone of possible removal of large droplets of liquid into the outlet duct.

More perfect with the position of the spray liquid, the interaction between the liquid and swirling air, and the subsequent separation of these two environments is totip).

The known method, taken as a prototype, includes the following operations: tangential entry of the air, twisting in a hollow vertical cylinder, spraying liquid from the axis of torsion, the separation of liquids from air counter-flow of the main flow of air along the axis of the torsion in the zone of suction, heated air and tangential output to the user.

Known device that implements the specified method and taken as a prototype, contains a fan, a pump and piping system, a cylindrical casing provided with spaced along the tangent to its circumference inlet and outlet nozzles, a tubular element forming with the housing an annular chamber, which is equipped with heaters, spray liquid, mounted on the axis of the tubular element in the upper part and the lower part of the tubular element fortified located with a gap relative to its end disk having a hole.

Thus, the installation consists of two cylindrical chambers of different diameters. Moreover, the camera of smaller diameter, which is fed tangentially original air enters a chamber of larger diameter, from which conditioned air tangentially displayed. In the chamber of smaller dies the reflective disk with a hole to feed the oncoming air, which is part of the core tangential flow. Lifting ring on the camera and podogrevali, the air is displaced upward and tangentially displayed.

The disadvantages of this method and device for its implementation is that the twisting of the original air in the hollow cylinder (tubular member) leads to the formation of a zone of discharge along the axis of the tubular element, which eliminates the use of the entire volume of the chamber for heat and mass transfer processes and requires a large diameter to reduce energy intensity by tightening the air. Counter stream of air is only valid in the area of exit of the mixture from the reflector, and not from the moment of spraying liquid. Flow counter flow along the axis of the winding does not increase the turbulence flow. These shortcomings lead to reduced efficiency of the heat transfer and the bulkiness of the design. In addition, the location of the heater heating the air in the chamber of large diameter at its periphery leads to an increase of metal and complexity of the design.

The present invention is to increase the efficiency of heat and mass transfer processes and reduce energy consumption for air due to the exclusion zone time is allaescort of a structure by the location of the heater heating the air in the outlet duct of smaller diameter.

To perform this task in the way of conditioning, including the creation of swirling primary air stream spraying irrigating fluid, separating excess liquid from air, heated air and output air-conditioned air to the consumer, irrigating fluid is sprayed on the circumference coaxial to the axis of winding of the main flow, additional vertical flow is injected into the area bounded by the circumference of the spray, the output of conditioned air produced by channel located inside the swirling flow.

To perform this task in installing, implementing the proposed method, which includes a fan, a pump and piping system, a cylindrical casing, inlet pipe, located tangentially to the housing, the output duct, the spray liquid, a reflector, a heater, a casing provided with an additional upper inlet pipe, the spray is made in the form located in the upper part of the housing coaxially with him annular pipe with injectors, covering the place of entry into the body for more top nozzles, the output duct mounted on the axis of the housing, and a conical reflector provided with a cylindrical visor and sucralfate installation.

Under cone reflector can be located lamellar separator.

The invention consists in that in the method of air conditioning irrigating liquid is sprayed koltseobrazno with the simultaneous flow of two streams of air in the tangential and vertical directions so that the sprayed liquid is initially between them. Tangentially introduced air captures the vertical flow of air from the annular spray with fluid particles. Moreover, the overlap of the two streams leads to a turbulent flow of air with particles of liquid and crushing with a simultaneous increase in the contact surface of two media throughout the volume of the body. Further twisting and movement of the liquid with the air carry around a vertical output duct, i.e. in the annular chamber, and not in the hollow cylinder. Spiral movement of the mixture separating liquid from the air and produce due to centrifugal forces on the surface of the cone reflector, which ensures an increase in the blowing velocity of the particles of liquid air. Cone reflector provides a transition spirally descending air with the sprayed liquid in versatilely with a minimum expenditure of energy due to the transformation of the energy of motion.

Installation for implementing the method of conditioning air is shown in Fig.1 is a General diagram of Fig.2 is a top view.

The air conditioning installation includes a cylindrical housing 1 and mounted on its axis output socket 2 with cone reflector 3, is fitted with guide vanes cylindrical shield 4 and the separator 5. In the duct 2 are heated, the heater 6, the throttle valve 7 and attached the fan 8. To the body 1 fits: tangential inlet pipe 9 with the throttle valve 10, an additional upper inlet pipe 11 with the throttle 12. In the upper part of the housing 1 is connected with the pump 13 ring of irrigation pipe 14 to the nozzle, which is connected through a system of tubes and tube fittings 15.

The output duct 2 and the annular pipe 14 mounted coaxially with the cylindrical body 1. The top of the inlet pipe 9 is set asymmetrically to the axis of the housing 1 within the area bounded by the circumference of the ring pipe 14. The tray setup, where the liquid may be supplied by heating Elements 16 for heating the liquid.

The device operates as follows. When starting the fan 8, the discharge from ATOR 5 in the housing 1. Under this action takes place as the tangential air supply through the pipe 9, and additional vertical air flow through the upper tube 11, causing turbulence. In the upper part of the housing 1 in these threads is served sprayed liquid is pumped from the sump setup by pump 13 through the annular irrigation pipe 14 to the nozzle. The temperature of the sprayed liquid may be supported either from the heating Elements 16, or from a supply of hot and cold water through the tube of the valve 15. The operation of the heating Elements 16, the supply of hot and cold water, as well as switching on and off of the heater 6, providing a second heated air is carried out automatically by means of the temperature controllers.

Liquid spray nozzles in the flow of air, fills it up to 100% relative humidity and heats to the required temperature. Then the mixture of liquid and air, spiral around the vertical duct 2 is lowered to the surface of the reflector 3, where the translational energy of the mixture is converted into rotational. 3A centrifugal forces, the liquid droplets are dropped to the periphery of the housing 1 and in the further movement of the mixture between the surface of the housing 1 and napravleno 4 and goes into the separator 5, and drops of liquid down into the sump along the wall of the housing 1. Part drops, blown with air, completely separated in the separator 5, and the air moves along the vertical duct 2 in a heater 6 which is heated to the required parameters of air temperature and relative humidity, then the fan 8 is sent to the consumer. Total consumption of prepared air regulated by the throttle valve 7, and the ratio of tangential and vertical air flow is set by the throttle valves 10 and 12.

Thus, the presence of additional upper 11 and 9 tangential nozzles, providing a supply of air in a cylindrical housing 1 increases the turbulence of the air flow and improves the interaction with the sprayed liquid. The presence of the vertical input exhaust with 2 conical reflector 3 provides a more efficient use of the internal space of the housing 1 without dilution zone and conical reflector 3 creates the unwinding of fluid particles with notification of centrifugal force with a minimum of energy expended and further effective separation of air from the liquid using a smart visor 4. All of the heater 6 in a discharge duct with a small diameter reduces the intensity and simplifies the design of air conditioning.

Use setup that implements the proposed method of conditioning air in line baking of bakery products for air treatment in rastey wardrobe showed that when the temperature of 24-28With, the performance in the air up to 7 thousand m3/h with output parameters on the relative humidity of 60-70%, at a temperature of 36-40With the energy consumption amounted to 10-12 kWh, which is lower in comparison with existing air conditioners of the same class in 1,5-2,0 times.
