Implementation of a group of utility models.

The air conditioner, as shown in FIG. 1, comprises a housing 1, an impeller 2 installed therein, and a humidifier 3. The impeller 2 is equipped with a drive (for example, a sleeve, a belt drive, etc., not shown in FIG.) For connecting to engine 4, and can be performed radial, axial and other types. The humidifier 3 contains the upper 5 and lower 6 water tanks from the nozzles 7 and 8, respectively, for supplying and discharging water, evaporation plates 9 of hygroscopic material, for example, mycoplast, placed with the formation of air channels between them 10. In the bottoms 11 and 12, respectively, of the upper 5 and the bottom 6 of the tanks made drainage holes 13. The evaporation plate 9 is also made with drainage holes 14. The evaporation plate 9 is connected to the tanks 5 and 6 by means of pins 15. The studs 15 can connect to the bottoms 11 and 12 of the tanks 5 and 6 by ohm of the support plates 16 and the threaded connection, including the thread at the ends of the studs (not indicated in Fig.), washers 17 and nuts 18, or otherwise. Thanks to this connection, the evaporation plates 9 can be mounted relative to the studs 15 at an angle equal to or close to 90 degrees.

The evaporation plates 9 are made with corrugation in the form of cylindrical surfaces 19 and platforms 20, the thickness of which exceeds the thickness of the evaporation plate 9, and the dimensions of the platforms 20 are larger than the dimensions (for example, diameter) of the drainage holes 14 (FIGS. 2, 3). While the studs 15, it is advisable to place on the end sections of the evaporation plates 9.

The air conditioner can be performed, as shown in FIG. 4, with several humidifiers 3 installed in the housing 1 and one impeller 2. In this case, the air conditioner is additionally equipped with a supply 21 and a drain 22 collectors connected respectively to

pipes 7 and 8 of the upper 5 and lower 6 tanks. In this case, the supply manifold 21 is connected to a source of clean water and is equipped with a device for supplying water. The source of clean water can be in the form of a reservoir 23. When the reservoir 23 is located above the uppermost tank 5 of the humidifier (Fig. 4), gravity water is supplied to the upper tanks 5. With another installation of the tank 23, the water supply device is designed as a pump 24 installed in feed header 21.

The air conditioner can be performed, as shown in Fig. 5, in the form of several humidifiers 3 connected to each other or to the housing 1, while each of the humidifiers 3 is equipped with its own impeller 2.

A humidifier for an air conditioner, the general view of which is shown in FIG. 6, comprises a housing 25 formed by upper 5 and lower 6 tanks interconnected by sidewalls 26, and evaporation plates 9 installed in the housing with drainage holes 14. Upper 5 and lower 6 tanks, as shown in Fig.7, are respectively made with bottoms 11 and 12, covers 27 and 28, feed 7 and drain 8 nozzles. In the bottoms 11 and 12 of the tanks 5 and 6, drainage holes 13 are made. The evaporation plates 9 are installed so that their drainage holes 14 are aligned with the drainage holes 13 in the bottoms 11 and 12 of the tanks 5 and 6, and pass through part of the holes 13 and 14 studs 15 connected to the bottoms 11 and 12 of the tanks 5 and 6. Studs 15 can be connected to the bottoms 11 and 12 as an integral or disconnected connection. When making a connection, detachable, for example, threaded, a thread is cut at the ends of the studs (not shown in FIG.), The studs pass through support plates 16 made with drainage holes (not shown in FIG.), Coaxial drainage holes 13, and onto the studs 15 nuts 18 resting on washers 17 are wrapped. Evaporation plates 9 are made with corrugation in the form of cylindrical surfaces 19 and platforms 20, the thickness of which exceeds the thickness of the evaporative

plate 9, and the dimensions are larger than the dimensions of the drainage holes 13 and 14 (Fig.2, 3).

The evaporation plates 9 relative to the studs 15 can be perpendicular or at an angle close to 90 degrees, and the implementation of the drainage holes 14 at the end sections of the evaporation plates 9 (Fig.7).

Evaporation plates 9 can be made in the form of packets, with adjacent packets. Through the part of the combined drainage holes 14 of the adjacent evaporation plates 9, studs 15 pass connecting the evaporation plates 9 with each other and with the bottoms 11 and 12 of the tanks 5 and 6 of the housing 25. The corrugation on the evaporation plates 9 located in adjacent packages is made from different sides. With the same height of the corrugations, this allows the formation of through channels between the evaporation plates 9, and due to the contact of the corrugations and the other side of the overlying evaporation plates 9, the stiffness of the housing 25 of the humidifier 3 increases. The junction of adjacent packages of evaporation plates 9 is closed, for example, by soldering, gluing strips 29 and in another way (Fig.6).

The humidifier pins 15 can be made in the form of tubes, the ends of which are located above the bottom 11 of the upper tank 5. For more even distribution of water on the surface of the evaporation plates, bundles of hygroscopic, for example, cotton paper material can be drawn through the drain holes 13 and 14 (in FIG. not shown), and on the bottom 11 of the upper tank 5, partitions can be installed, for which support plates 16 can be used.

Humidifiers can be combined with each other, forming a modular humidifier. Moreover, as shown in Fig. 8, such a modular humidifier is equipped with a supply 21 and a drain 22 collectors connected respectively to the supply 7 and drain 8 nozzles,

the supply pipe is connected to a source, for example, a pure water tank 23. The pure water tank 23 may be located above the upper row of humidifier modules, and pure water is supplied to the upper tanks 5 and 6 by gravity. With a different arrangement of the pure water tank 23, a pump 24 is built into the supply manifold 21.

Air conditioning and humidifier work as follows.

Through the inlet pipe 7, pure water is supplied to the upper tank 5, and through the drainage holes 13 and 14 it enters the surface of the evaporation plates 9 and spreads along it. Passing through the air channels 10, the air pumped by the impeller 2 is saturated with water vapor. In this case, the air is cooled, and the dust inside it settles in the water film on the evaporation plates 9. Unevaporated water together with the dust settled in it through the drain holes 14 flows into the lower tank 6 and is removed through the outlet pipe 8.

When the surface of the platform 20 of the evaporation plate 14 is positioned with respect to the studs 15 at an angle close to 90 degrees, water spreads faster along the surface of the evaporation plate 9, which increases the flow rate of clean water and contributes to its more intensive evaporation and higher air filtration. When the location of the evaporation plates 9 perpendicular to the studs 15 reduces the flow of clean water.

The achievement of the technical result, namely, the provision of humidification, cooling and air purification, is confirmed experimentally. Humidification and cooling of the air when passing through the humidifier at high and low temperatures is shown in the graph in Fig.9. When air passes through humidifier 3, the air is not only saturated with water vapor, but also changes its temperature, and the difference between humidity and temperature at the inlet and outlet of the air conditioner (or humidifier) changes with increasing flow velocity Va (and, consequently, the flow rate L) passing through a humidifier.

It was experimentally established that when passing through humidifier 3, the air is not only humidified, but also cleaned, and the degree of purification is close to the degree of purification of air passing through a dry filter of corrugated filter material (pocket filter), which is confirmed by the following experimental results:

Experiment Parameters unit of measurement Pocket filter Suggested humidifier Test Flow L, cubic m / hour 700 700 Aerodynamic drag ΔP, Pa 34 80 Dust mass gram 104.5 95.19 Absolute filter mass gram 19,884 20,131 Absolute filter mass after testing gram 41,507 40,311 Dust mass slipped through gram 41,507-19,884 = 21,623 40,311-20,131 = 20,180 Slip rate % 21.623 / 104.5 = 20.8% 20,180 / 95.19 = 21.2%

The aerodynamic resistance of air (or pressure loss) passing through the humidifier 3 is higher compared to a dry filter bag made of woven material. Presented in figure 10, the pressure loss passing through the claimed humidifier, in all likelihood, will not exceed the pressure loss when passing air through a sequentially located pocket filter, humidifier and cooler.

Thus, the air conditioner and humidifier presented in the application provide both humidification and cooling and air purification.

The completeness of the disclosure presented in the description of the utility model of the air conditioner and the humidifier used in it allows them to be manufactured at any specialized enterprise. In this case, the humidifier can be manufactured as a product that can be used in other devices, other than those described in the description of the air conditioner, for air treatment.
