Description

The invention relates to techniques for air conditioning and ventilation and can be used to create comfortable conditions and microclimate in domestic, administrative and industrial premises.

The closest technical solution to the claimed object is air conditioning according to the patent of the Russian Federation No. 2067730, class. F 24 F 3/06 dated 10.10.96, comprising a housing, sections for receiving valves and heating, an irrigation chamber in which nozzles and drip traps with a filter pan are installed, a filter section connected to the ventilation unit.

Its disadvantage is the relatively low efficiency of the dropping process.

The technical result is an increase in the efficiency and reliability of the process of splashing.

This is achieved by the fact that in an air conditioner containing a section of receiving insulated valves, connecting sections, a first heating section, consisting of heaters, valves and a bypass channel, a first recirculation section, an irrigation chamber in which nozzles and drip traps are installed, and a drip tray is located under the irrigation chamber - a filter, and after the irrigation chamber there is a second recirculation section and a filter section connected to the second heating section, consisting of heaters and connected to the ventilation unit the droplet eliminators are made in the form of a package of partitions, one of which is a baffle element with a through hole, and the others are perforated with a perforation coefficient of 0.5, and following them, at least three rows of plates having a slope from the upper plane to the lower, and in the cross section perpendicular to the length, a wedge-shaped streamlined shape, and the casing is mounted on elastic elements, and the suction pipe of the fan is connected to the casing by means of an elastic link, moreover, the fencing element with a through hole from the package and the partitions are installed last in the bag, and the ratio of its height "b" to the height of the through hole "c" is in the optimal range of values: b / c = 2 ... 5, and the gap between the partitions in the package of partitions is 0.01 .. .0.1 from their height.

Figure 1 shows a General view of the air conditioner, figure 2 is a section of the plates of the drip tray, figure 3 is a section of perforated and baffle plates.

The air conditioner consists of a series of series-connected sections (figure 1).

The section of the receiving insulated valves 1 controls the flow of outdoor air into the air conditioner. The valves are made insulated to protect them from freezing and icing in the winter. The connecting sections 2 are chambers that connect the working sections; through these cameras access to the working sections is possible for inspection and repair.

The section of the first heating follows, which serves to heat the outside air in the amount of the sanitary norm; it consists of air heaters 3, valves 4 and a bypass channel 5. Valves 4 can direct outside air into the air heaters 3 or, bypassing them (in summer), into the bypass channel 5. In section 6 of the first recirculation valves 7 are installed that regulate the flow of internal air from the workshop. Section 8 is an irrigation (nozzle) chamber, in which two rows of nozzles 9 are installed, spraying water with oncoming torches. In the irrigation chamber, the air is humidified or dried, if necessary, cooled or heated, and also cleaned of dust. In addition, the air in the irrigation chamber is charged with ions, mainly of a negative sign. At the inlet and outlet of the irrigation chamber, droplet eliminators 10 and 11 are installed. The droplet eliminators prevent droplets from dropping from the irrigation chamber into adjacent sections.

Drop eliminators are made in the form of a package of partitions 10 and 11, each of which contains a baffle element with a height "b" with a through hole "c" (Fig. 3), perforated partitions with a perforation coefficient of 0.5, and at least three following them a number of plates (figure 2) having a slope from the upper plane to the lower, and in the section perpendicular to the length, a wedge-shaped streamlined shape. The casing is mounted on the elastic elements 25, and the suction pipe of the fan is connected to the casing by means of an elastic link 24. The baffle element with the through hole from the package of partitions 10 and 11 is installed in the package last, and the ratio of its height "b" to the height of the through hole "c" is in the optimal range of values: b / s = 2 ... 5. The gap between the partitions in the package of partitions 10 and 11 is 0.01 ... 0.1 of their height.

Under the irrigation chamber is a pan - filter 12 for swelling and purification of water. After the irrigation chamber there is a section 13 of the second recirculation with valves 14, which regulate the flow of air from the workshop. To clean the air from dust, a section of 15 filters is installed. This is followed by the connecting section and the second heating section, consisting of heaters 16, valves 17 and the bypass channel 18, the purpose of which is the same as in the first heating section. This section is used during working hours with a lack of heat in the hall, and on weekends - for heating the production room; in this case, the valves 14 of the second recirculation are opened and the air conditioner operates as a heating unit. At the end of the air conditioner, a fan section is installed, consisting of a fan 19, an adapter pipe 20 and an electric motor 21. Dosing valves 23 are installed on the day of the air supply control in the workshop in the supply duct 23. Air supply can also be regulated by a guide apparatus 24. For convenience, air conditioners are usually installed on elastic supports 25.

Air conditioning works as follows.

The considered typical sections are arranged depending on the required air treatment processes. For example, if the calculation does not need the first or second air heating, then the need for these sections disappears. If the installation should work without recirculation, then the air conditioner is assembled without these sections.

Air conditioners with a capacity of up to 120 thousand m ³ / h are made of metal, and air conditioners of greater productivity are made of reinforced concrete.

To reduce the vibro-acoustic activity of the apparatus and its metal consumption, as well as to increase its reliability, the proposed device provides the following measures: a layer of soft vibration-damping material, for example, VD-17 mastic, is applied to the surface of the parts, and the ratio between the thickness of the metal and the vibration-damping coating is in the optimal range of values: 1 / (2.5 ... 4).
