Description

The utility model relates to ventilation and can be used in a building ventilation system.

A device for improving indoor air is known, including supply and exhaust fans and ionizers, made in the form of saturators filled with a potassium-salt mixture and installed in the supply channels with the possibility of periodic rotation. (See Pat. To IZ No. 2133921, IPC F24F 3/16).

In a known device, air is additionally purified by filtration through saturators into the room. Saturators are filled with therapeutic potassium-salt compound, which ensures inhibition of pathogenic factors in ventilated rooms and saturates the air in the room with therapeutic ingredients. Activation of dosages of medicinal ingredients is achieved by additional artificial rotation of the saturator cylinder.

A disadvantage of the known device is that it has limited functionality due to the lack of regulation of the concentration of therapeutic ingredients in the supplied air. Another disadvantage is the inability to supply any other gases to the air due to the lack of necessary transitional devices.

A known installation for heat supply, cooling and ventilation of rooms, including a heat pump connected to the storage tank and heating pipelines, a ventilation system with supply and exhaust ducts, a recuperator connected to the ducts of the ventilation system, temperature sensors located on the installation elements, inside and outside premises, and a device for monitoring and controlling the installation elements in accordance with the readings of the sensors. (See Pat. PM No. 75015, IPC F24J 2/00).

The known device carries out air ventilation while heating it.

A disadvantage of the known installation, as well as in the first analogue, is the limited functionality due to the inability to regulate the gas composition of the air in the room.

The closest in technical essence and the achieved result is the supply and exhaust ventilation, including discharge and exhaust fans, ventilation ducts, exhaust and exhaust. (See the Textbook edited by the Doctor of Technical Sciences, Professor Bogoslovsky V.N., M., Stroyizdat, 1976, pp. 144-152, Fig. X.10, X.12, X. 17, X.18. Prototype).

Ventilation of the prototype ventilates the air in the room while cleaning the air supplied to the room.

The disadvantage, as well as in analogues, is limited functionality, since the prototype device does not provide for the supply of various gases (for example, oxygen) and the regulation of their concentration in the room air.,

These shortcomings are eliminated in the proposed technical solution.

In the proposed device for supply and exhaust ventilation, an additional vessel is installed that contains gas, for example, oxygen under pressure, a ventilation valve integrated at the inlet of the discharge duct, a gas pipe integrated at one end into the discharge duct and located above the ventilation valve, connected at the other end with a vessel containing gas under pressure, while a solenoid valve is connected to the microcontroller, including a sensor for the concentration of supplied g the basics.

Coma of this:

- the device is additionally equipped with a time relay;

- the device contains the nth number of vessels with various gases under pressure;

Comparative analysis with the prototype revealed the following significant distinguishing features:

- the device is additionally equipped with a vessel containing gas, for example, oxygen, under pressure

- the device is equipped with a ventilation valve built into the inlet of the discharge duct

- the device is equipped with a gas pipe integrated at one end into the discharge duct

- the gas pipe is located above the ventilation valve

The other end of the gas tube is connected to a vessel containing gas under pressure. A solenoid valve is connected to the gas tube. It is connected to a microcontroller, which includes a sensor for the concentration of the supplied gas. Additional distinguishing features:

- the device is additionally equipped with a time relay.

- the device contains the nth number of vessels with various gases under pressure.

The presence of these distinctive features ensures compliance of the claimed technical solution with the condition of patentability "novelty" under applicable law. Information about the analogues of the claimed device made it possible to establish that there are no analogues characterized by features identical to all the essential features of the proposed utility model, and the selection from the list of analogs of the prototype ensured the identification of a combination of distinctive features of the claimed technical solution relative to the technical results.

The task to which the proposed technical solution is directed is to ensure the supply of various gases, for example, oxygen and the regulation of its concentration in the room air.

The technical result that is achieved by solving the problem is expressed in creating a healthy atmosphere that can increase efficiency, as it is considered established that workers who constantly inhale oxygen with a concentration at a concentration level outdoors have an unhindered blood flow, which strengthens immunity, decreases the frequency of acute respiratory infections.

Supplemental oxygen is necessary for people who constantly live in a metropolis, as it helps the body overcome the negative impact of the external environment; in people with intellectual labor, supplemental oxygen helps to increase concentration and reduce fatigue. Supplemental oxygen can be used for medical purposes, for the treatment and rehabilitation of people after myocardial infarction, for the treatment and prevention of chronic bronchitis, asthma, acute and chronic respiratory failure, etc.

The problem is solved in that the device for supply and exhaust ventilation is additionally equipped with a vessel containing gas, for example, oxygen under pressure, a ventilation valve integrated at the inlet of the discharge duct, a gas pipe integrated at one end into the discharge duct and located above the ventilation valve, and the other end connected to a vessel containing gas under pressure, while in the gas tube is integrated an electromagnetic valve connected to a microcontroller containing a sensor concentration of the supplied gas. In addition, the device is additionally equipped with a time relay and contains the nth number of vessels with various gases under pressure.

Figure 1 - General view of the device. Work in the automatic mode.

Figure 2 - General view of the device. Work in manual mode.

Figure 3 is a General view of the device with the n-th number of vessels with various gases.

The device for supply and exhaust ventilation contains a blower fan 1 and an exhaust fan 2. Blower duct box 3, the final section of which is installed in the ceiling part (not shown in drawing) of a room 4. An exhaust duct box 5 is installed at the outlet of the ventilation system. A ventilation valve 6 is integrated at the outlet of the ventilation pressure duct 3. A gas pipe 7 is integrated at one end into the ventilation pressure duct 3 and is located above the ventilation valve 6. The other end of the gas pipe 7 is connected to the vessel with gas 8 containing gas under pressure. An electromagnetic valve 9 is integrated in the gas tube 7. The electromagnetic valve 9 is connected via an operating mode switch 10 to the microcontroller 11 and a time relay 12. The concentration sensor of the supplied gas 13 is connected to the input of the microcontroller 11. Using the collector 14, an nth number of vessels 8 can be connected various gases (under pressure) to the ventilation system.

A device for supply and exhaust ventilation works as follows:

The gas supply device (for example, oxygen) (see figure 1) in the supply and exhaust ventilation system is as follows:

The injected air is fed into the room 4 with the help of the blower fan 1 through the blower duct 3 and the blower valve 6 (valve 6 is mounted in the ceiling of the room 4 and at the outlet of the blower blower 3). The used air is discharged from room 4 through an exhaust ventilation duct 5 using an exhaust fan 2. Gas from a vessel 8 is supplied to a pressure ventilation duct 3 through a gas pipe 7. The gas supply to the ventilation system is switched on and off using an electromagnetic valve 9. Gas supply ( for example, oxygen) to the ventilation system can be made in two modes: manual and automatic using switch 10.

In the manual mode (see Fig. 2), the user, using the switch 10, connects the electromagnetic valve 9 to the time relay 12 and simultaneously turns off the microcontroller 11 with the sensor 13 connected to it.

The gas supply and shutdown are regulated by a time relay 12, on which the user sets the open time of the electromagnetic valve 9 (i.e., the time of gas supply to the ventilation system). After the set time has elapsed, the time relay 12 is activated, and the electromagnetic valve 9 shuts off the gas supply to the ventilation system. In this case, the concentration of the supplied gas in the air of the room 4 is determined by the well-being of the consumer. The time relay 12, the user turns on if necessary.

In automatic mode (see figure 2), the gas concentration in room 4 is maintained automatically. Using the switch 10, the user connects the electromagnetic valve 9 to the microcontroller 11, to which the sensor 13 is connected (the sensor 13 measures the gas concentration in the room air 4) and simultaneously turns off the time relay 12. If the gas concentration, for example, oxygen, is exceeded in the room air 4 sensor 13 receives a signal to microcontroller 11, which gives a command to close the electromagnetic valve 9. The latter shuts off the gas supply to the ventilation system. When the concentration of gas in the air of the room 4 decreases, a signal is sent from the sensor 13 to the microcontroller 11, which gives the command to open the electromagnetic valve 9, while the flow of gas, for example, oxygen, to the ventilation system is resumed.

To expand the functionality of the ventilation system, it is possible to use the collector 14 (see Fig. 3) to connect the nth number of vessels 8 with various gases (for example, for the treatment of pulmonary patients - oxygen or a salt-containing gas mixture, for extinguishing a fire - carbon dioxide, for applications in recording studios for changing the timbre and pitch of the voice - helium gas, as well as for aromatherapy, where appropriate gas mixtures can be used, and to supply these gases in a certain sequence or in certain combinations depending ing on to be solved by the user task.

The proposed device for supply and exhaust ventilation does not cause difficulties in its manufacture and installation and is already industrially mastered.

The foregoing indicates for the claimed device, as it is described in the formula of the utility model, about the possibility of implementing it using known and proposed methods and means.

Therefore, the proposed utility model meets the patentability criterion of “industrial applicability” under current law.
