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. F24F 3/06 of 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 irrigation process.

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

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 In addition, a centralized cold water supply system is installed, which includes an irrigation chamber with a pump and a three-way valve, as well as a pressure regulator, a collection tank, a circulation pump and an evaporator, each pressure regulator having a pulse tube connecting its membrane head with a membrane located behind it section of the cold water supply pipeline, 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.

Figure 1 shows a General view of the air conditioner, figure 2 presents a system for centralized supply of air conditioners with cold water.

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 being emitted into the adjacent sections.

Under the irrigation chamber is a pan - filter 12 for draining and purifying 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 second recirculation valves 14 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. To regulate the air supply to the workshop, metering valves 23 are installed in the supply duct 22. on elastic supports 25.

Figure 2 presents a centralized supply system of air conditioners with cold water. The system includes an irrigation chamber 26; pump 27; three-way valve 28; pressure regulator 29; collection tank 30; circulation pump 31; evaporator 32; valve 33.

Each pressure regulator 29 has a pulse tube connecting its membrane head with a portion of the cold water supply pipe located behind it.

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.

The heated water is collected in a common collection tank 30, from which it is taken by a circulation pump 31 and supplied through pipelines for cooling to the evaporator 32 of the refrigeration station. After the evaporator, it is fed directly to the three-way valves 28 installed on the suction line of individual pumps 27 serving individual irrigation chambers.

Heated water is also supplied to the valves from the air conditioner trays. For satisfactory mixing of the incoming water and the normal operation of the three-way valves 28, an approximate equality of the pressures of cold and heated water in front of them is necessary. It is achieved by installing automatic pressure regulators 29 ("after yourself") on cold water lines.

When the pressure deviates from the set value, the valve moves accordingly: when the pressure rises, it closes, and when it decreases, it opens.

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).
