Inside the tank 1 on the cone-shaped MAIN, the bottom is free perforated bottom 2 of convex shape. False bottom 2 provides an opportunity by adjusting the level of febfibi in reservoir 1 to create conditions of water, water, land and land ..

Through the holes in the false bottom, 2 metabolite fluids are removed from reservoir 1.- The installation also includes. . tank 3 for the preparation of water and air at a given temperature. and humidity. The useful volume of the tank 3 is in addition: it is just over the useful volume of the tank 1, which is necessary to reduce the influence of the temperature mode of the external medium on the temperature setting mode. In addition, the level of the location of the tank 3 is higher than the level of the open reservoir 1. This ensures the natural flow of water from the reservoir 3 to the reservoir 1, which is necessary and the normal functioning of the installation.

Capacity 3, is equipped with a device for aerai-water, 1 Exhausted in the form of a heat harter 4, enriched with water and oxygen and two snake humidifiers 5 and 6, as well as a dephlegmator. . yO serpentine tubes 7 for iodine-. Chy ts coolant. Reflegmator is an airing V. as a hermetic dome-shaped cover with regulators; very bright .TOJieM 8 and a mesh cone-shaped: base. The reflegmator is intended for the evaporation of water from the tank 3. The tanks-1 and the tank 3 are interconnected by a pipeline connection for the closed circulation of water and the half-open air circulation and are equipped with control systems, control and automatic control of the set parameters in air and air in installation. The closed loop system includes

filter system 9, circulating gear pump 10 with a drive, cylinder 11 (type pipe in pipe or serrated pipe), two-section electric heater 12, implemented fta standard electric heaters of TEN type, in which one section is constantly switched on during heating and the other is controlled from the regulator 13. In addition, the closed-circuit water circulation system includes control valves 14 and 15 for changing the ratio of the water levels in the tank 1 and the tank 3, the drain pipe with valve 16 and valve 17. According to Lednov together with a valve 14 for supplying Vod through the valve 15 in a closed flow circuit (without direct flow in. the container 1).

Refrigerator 11 and two sections: electric heater 12 are designed to regulate water temperature and

Half open circulation system

: and air preparation for the given parameters (temperature, humidity, pressure) includes an air supply device containing a reversible blower 18 connected to the power supply stabilizer 19, piping comms with control valves 20, 24, and also; control valves 25, and 26 and bilge columns. 27. For Water leakage from the bubbler 3 tank is also prevented. 4 valve 20 is made to reverse. The system of half-open circulation and air conditioning of pre-set: Mrameters. It should be maintained in tank 1 as excessive, and so on. Lower pressure at a given temperature and humidity. -.

The control and monitoring system is designed to support a given temperature, water and air and the relative humidity of the latter, as well as to control the pressure and temperature of the air in the reserve area 1.

The automatic water temperature control system consists of a thermometer-resistance 28 (of type TOM Gy-21)., An automatic bridge with an on-off electric regulator 13, a logic device 29 implemented on standard elements of industrial pneumatic automation, a magnetic actuator AOR, and a control valve 31 with a solenoid actuator 32 control The pressure consists of a sampling device and a self-recording pressure gauge, for example a bellows-type system. 33 The control of relative humidity of the air includes measuring rer relative vlazhch air spine, for example a semiconductor thyristor, automatic potentiometer equipped with pneumatic PID regulator, control valves 25 and 26, one of which is normal open and the other normally closed. Thus, the proposed installation provides the content of living organisms in the conditions of the aquatic environment, the aquatic environment — land and land at given values of temperature, pressure, and air humidity, at a given temperature and gas regime of water with simultaneous purification. At the same time, water and air in the installation have the same temperature. The specified conditions for the maintenance of living organisms in the installation are provided by varying the level of water in reservoir 1 as follows. . In the tank 3 pour water. Maintaining the constancy of the salt composition of the aqueous medium, for example, sea water, is ensured by preventing the evaporation of water in the capacitance 3 by means of a dephlegmator connected via refrigerator 7 to the refrigerator. Through the power supply stabilizer 19, a reversible blower 18 is included in the operation, and air is supplied through the valve 22 and the non-return valve 2O. on the bubbler 4 to saturate the water with oxygen. Excess air is discharged sequentially through the reflux condenser and the adjusting valve 8 / In the tank 1 by means of the valves 14, 15 and 17 and the circulation pump 10 they create the condition of the aquatic environment, the aquatic environment of land or only land. When the valve is opened 14, the water from the tank 3 flows by gravity into tank 1, while water is fed into tank 1 until the top of the false bottom 2 is hidden under the water. in this case, in reservoir 1, the conditions for the content of living orbits are the same as in an ordinary aquarium; valve 17, by circulating pump 1O, water is supplied through a cleaning filter 9 through pipe communication into the tank 3. With constant performance of the pump 10 and a change in the conductivity of the valves 14 and 17, the water level can be changed from the maximum filling to its complete removal from the tank 1. When changing the degree of discovery. valve 14, the flow rate of water through it is equalized with the capacity of the circulation pump 10 at the new steady state level in tank 1 due to the self-regulation of the system. In this case, the false bottom 2 is partially flooded with water (as shown in the drawing), forming an island for placing animals on leaving water. The sushi condition in the setup is created as follows. Shut off valve 14 and completely remove water from tank 1 successively through valve 17 and filter 9 by means of circulation pump 10. After that, valves 17, 14 are closed and valve 15 is opened. In this case, water is circulating, mine 1 , and in the reserve jape 1 sushi conditions are created. At the end of the experiments, the valve 8 is fully opened and water is drained from the tank 3 to the sewage through the pipe with the valve 16. In the process of water circulating through the closed circulation circuit, the water is thermostatically controlled, cooled in the refrigerator 11 or heated in the electric heater, before entering the tank 3 12, in which one section in the heating process is turned on permanently, and the other is made controlled from the regulator 13. The desired temperature of the water and air is created by controlling the control system with kpH temperature control as follows: in a way. The signal about the value 1 of air temperature in the tank 1 from the thermometer - the resistance 28 goes to the regulating device 13 and through the logic element 29 changes positionally or the transfer of the refrigerant to the refrigerator 11 by opening the ventilation unit 31, or heating by permanently turning on the main power of the electric heater 12

on the PSx; that is the NN mode from the logic element 29 and the positional switching on of the regulating power of the electric heater 12 of the DZ actuator. The temperature of the air is maintained at the same time as the injected air passes through the system of coils, the bubbler and the water column in the tank 3 and is thermostatically controlled.

. The magnitude of the set temperature is set directly on the controller 13. The required gas mode is provided by continuously supplying air to the bubbler 4.

The relative humidity of the air is maintained by means of a humidity sensor, a regulator 33 and valves 25 and 26 installed on the lines of thermostatically controlled air of the dried and humidified air in the tank 3.

The air injected into the tank is branched into two streams - into the bubbler 4 through the check valve 20 and directly into the coil 5, from which air enters the drying columns 27 and through the adjustable valve 25 into the tank 1. Moistened to a saturated state during the sparging process the air enters into the coil pipe 6, located above the surface of the water, and re-thermostatically controlled in the coil 6 to eliminate the effect of low temperature in the area of the reflux condenser. Then the air enters through a controlled valve 26B tank 1.

When the relative humidity in tank 1 is changed, the ratio of the flow of moist dry air is automatically changed by means of valves 2 and 26 controlled by regulator 33. In this case, the temperature regime is not disturbed. The set value of the relative humidity of the air is preset on the controller 33. The system for maintaining the specified pressure mode ensures maintenance in the installation. overpressure or underpressure. In overpressure mode, valves 21 and 23 are closed, valves 20, 22 and 24 are open. Blower 18, set in motion by a reversible motor, entangled from voltage regulator 19, provides constant performance and pumps air

through the vents 22 and 20. into the tank 3 and further through the pipelines with the adjusting valves 25 and 26 into the tank 1. The change in the well pressure

In tank 1, the conductivity value of the exhaust valve 24 is changed.

The value of opening the valve 8 is regulated in such a way that the pressure

inside tank 3 was slightly larger than the pressure in tank J.

In the vacuum mode, the valves 22 and 24 are closed and the valves 23, 21 and 20 are open. The blower 18, due to the re-alignment of the engine, operates to discharge air from tank 1. Air from tank 1 through valve 23 is blown off by fan 18 to atmosphere. The vacuum created in the tank 1 provides fresh air through the valve 21. Fresh air is passed through a system of thermostating and moisture changes. similar to the mode of excess pressure. The degree of dilution B in tank 1 is regulated by changing the output of valve 23.

In order to more fully and quickly saturate the water with oxygen when operating the system in a dilution mode with maintaining 0% humidity in the tank 1, the branch pipe with the valve 8 must be connected to a reversible blower 18 by means of a pipeline with an adjusting valve (not shown). In this case, the air through the air intake manifold with the valve 21 enters through the non-return valve 20 and to the barboreter 4.

The proposed installation makes it possible to maintain in the working volume (i.e., in tank 1) the temperature of the aqueous medium practically from the freezing point and

to the boiling point with simultaneous adjustment of its purity and gas regime.

- In addition, the air temperature with

given humidity can be regulated .V

also in the temperature range

not from the freezing point to the point of ki. water foaming. Relative air humidity can be adjusted within O-100% with simultaneous adjustment of pressure) 1i.
