The cooler may consist of a first stage of cooling, in the form of cooler 11, and the second stage cooling is made in the form of a water-to-water cooler 12. The first section of the base pipe 6 connects the output of the injection pump 1 air cooler 11, and what ielem which is for example, artesian water.

Water cooler 12 is connected by a pipe 13 with a deep pumps 14 artesian water, which is protected by pressure protective device, such as a safety valve 15 mounted on the pipe 16 connecting the entrance hole pump 14 with the output. The pipe 13 has a regulating valve 17, functionally associated with the temperature sensor 18 mounted on the output water-to-water cooler 12.

Output water-to-water cooler 12 the third section of the base pipe 6 is connected to the consumer 19 cold circulating water. On the same lot as the main pipe 6 is connected to the auxiliary pipe 20 cold water, for example, the city. The pipeline 20 is installed control valve 21, the actuating mechanism is functionally connected with the pressure sensor, installed on the main pipe 6 or the auxiliary pipe 20 after the valve 21. In the particular case of the valve 21 has a diaphragm actuator 22, namebrand cavity which pulse pipe 23 is connected with the main pipe 6 or the pipe 20 after the valve 21. In this case, the control valve 21 is executed normally OEM pipe. The inlet tank 25 is connected transitional pipe 26, separated by a valve 27, with the auxiliary pipeline 20.

The fourth section of the base pipe 6 connects the output of consumer cold 19 with the preliminary stage of cooling, such as air cooler 28.

In addition, the input and output of consumer cold 19 is connected through a circulating pump 29 bypass pipe connected to the main pipe 6 by means of the regulating valve 30 mounted on it and is functionally associated with the temperature sensor 31 installed after the control valve 30 on the main pipeline 6. When this control valve 30 may be a three-way and perform the role of the mixer.

And also on the main pipe 6 can be installed heater 32, functionally associated with the temperature sensor 31 installed after the heater 32.

Shut-off and control device 9 (Fig. 2) contains the actuator 33, which is functionally connected with the temperature controller 34, the inlet of which is connected to the temperature sensor 18 that is installed, for example, at the output of water-to-water cooler 12 on the main pipeline 6.

The control valve 17 (Fig. 2) is Anosov 14. The actuator 35 of the valve 17 is also connected with the temperature controller 34.

These two actuator 33 and 35 dependent through limit switches valve, for example via intermediate relay 36, which is electrically connected limit switch 37 - detector full opening of the control valve 17, for example, through contacts 38, and the limit switch 39, for example, through their contacts 40, shut-off and control device 9. Limit switch 39 - detector full closing shut-off and control device 9. Relay 36 has a locking contacts 41 and the contacts 42 and 43, disable automatic control systems. Actuators 33 and 35 are also electropositive 44 installed in the control circuit shut-off and control device 9 and the valve 17 between the contacts 42 and 43 connected to the temperature controller, and actuators 33 and 35.

The entrance and you Amiternum regulating valve 47 with the Executive mechanism 48, functionally associated with the actuator 33 shut-off and control device 9, thus locking the regulating device 9 is made in the form of a two-way valve. In this implementation of the system actuators 33 and 48 are connected in antiphase, i.e., when the valve 47 is in the closed position, the shut-off and control device 9 is in the open position. The actuator 48 has a starter 49 (Fig. 6) connected to the same temperature controller 36 through contacts 43.

Before injection pumps 1 and after them can be installed check valves 50, 51.

When performing air cooler 11 in the form of the tower of the contact execution (Fig. 7) cost-effective before him and after him to install additional injection pumps 52 and 53.

When performing a water recycling system according to Fig. 8 as a consumer of cold 19 will be used delegatory apparatus distillation column, cooling water outlet temperature is 65oC. At the outlet of the pressure tank 25, the pipe 54 connecting the latter with the main pipe 6, or on the secondary pipeline 20 is a reverse Cluny valve 56. After the connection point of the auxiliary pipe 20 with the main pipe 6, before entry into the consumer cold 19, a heater 32. At the inlet and at the outlet of the circulation pump 29 accordingly, it is possible to install a check valve 57 and reducing device 58. The inlet and outlet of the circulation pump 29 connected to an additional by-pass pipe 59 has mounted on control valve 60, the actuator 61 which is functionally connected with the pressure sensor 62 water in the pipe after the valve 60. On the main pipeline 6 additional installation of the control device 63.

In this example, a scheme introduced delegatory tank 64, the inlet of which the main pipe 6 is connected to the output of the consumer cold 19, with delegatory tank 64 has an outlet pipe 65 for use heated water for household needs. Output delegating tank 64 is connected to the air cooler 28.

On the main pipe 6 (Fig. 9) may be mounted ejector 66 before entering the consumer cold 19, through which its associated input and output through the bypass pipe 67 is installed on the control valve 68 to fulfill the figures on the main pipe 6 after the ejector 66.

In the system (Fig. 10) can be entered multiple coolers as to the buffer tank 45, and after it. They can consist of series-connected water-to-water coolers 72 and coolers 73 connected between a main pipeline 6.

In another example (Fig. 11) an easier way system the implementation of water recycling in the production and rectification of alcohol, the output of consumer cold (delegating apparatus) tap 74 is connected to the input of water-water heater 75, the output of which pipe 76 is connected to the main pipe 6. The outlet 74 and tube 76 with cavities of water-water heater 75 form a coolant channel, the channel is heated dephlegmators water. At the outlet 74 is installed control valve 77, the actuator 78 which is functionally connected through a regulating device 79 with temperature sensor 80 installed on the main pipe 6 after the heater 75. When installing the heater 75 is directly on the main pipeline 6 he in this case is the channel supercooled water.

On the other hand, city water may be preheated before entering the pressure tanks 25 or h is positive the pipeline 20 city water, in this case, the inlet and outlet of the heater 75 is the pipeline 20 and the temperature sensor will be installed on the pipe 20 (Fig. 13, 14) after the heater 75. If delegatory water enters the heater 75 by gravity, it is set below the consumer's cold 19.

The pipe 54, which is the output pressure of the tank 25 (Fig. 15), can be mounted control valve 81, the actuator 82 which is functionally connected with the pressure sensor 83, mounted on the nozzle 54 or on the main pipeline 6. The actuator 82 is made, for example, membrane and pipe 84 is connected with the pipe 54 after regulating valve 81 or with the main pipeline 6.

The auxiliary pipe 20 and the pipe 54 are isolating valves 85 and 86, and the buffer tank 45 and the pressure tank 25 can have level controls 87 and 88, made, for example, float.

Before entering artesian pump 14 is installed a check valve 89, and the pipe 13 artesian water can be connected with the pipe 6 by means of an automatic mixer, for example using the three-way valve 90, the actuator 91 through which the controller functionally connected to the sensor t is idamay water (Fig. 17) may be made in the form of two control valves 93 and 94, one of which is installed on the main pipe 6, and the other on the pipeline 13, actuators 95 and 96 through which the regulating device is functionally connected with the temperature sensor 92 and connected in antiphase, i.e., when the valve 93 is closed, the valve 94 is opened.

Finally, the mixer can be made of one of the valve 94, the actuator 96 which is functionally connected through the controller with temperature sensor 92 (Fig. 18).

Mixer artesian water and cooled (Fig. 19) may also consist of one valve 93, which is a controller functionally connected with the temperature sensor 92. In this case, the pipe 13 is constant refrigerant flow rate.

In Fig. 22 shows an example of a structural diagram of the use of secondary hot water for sanitary and domestic use.

In this case, the intermediate storage capacity, for example delegatory tank 64 is connected with the other cumulative capacity of 97, which is, for example, in the elevators, which are interconnected through line 65. While the capacity of 97 automated level, for example, by means of the float regulator is automated by level, for example, using a float valve 101. For this case the output of the main pipe 6 is made slightly higher exit delegating tank 64, as storage capacity, in order first to use thermal energy of the non-refrigerated circulating water for domestic and industrial needs of the enterprise, i.e., the pipe 65 is made below coming from the tank 64 of the main pipeline 6.

At the same time, there is one more additional option considered by the example (Fig. 23), which shows an example of automatic switching its functional scheme, depending on the level in the storage tank 98 or dephlegmation tank 64. In this example, parallel dephlegmation Baku 64 includes a bypass pipe 102. More precisely, the main pipe 6 is connected with a storage capacity of 64 or 97 lateral pipeline 102, through the automatic switch 103, the actuator 104 which is functionally connected with the sensor 105 level installed on the accumulation tank 64 or 97. The switch 42, 24 may be made of two valves, the valve 106 mounted on the main pipe 6, and the valve 107, is installed on the pipeline 102, Executive mechanimals closed, the other normally open.

Injection pumps 9 and 14 can be motor-driven automatic rotation speed of the rotor of these motors.

In Fig. 25 shows an example of a structural diagram automatic control of the pump 9 and 14 by means of electronic blocks of the rotor speed of their engine.

As such control the rotational speed of the rotor of the electric motor 110 and the pump 9 and the motor 111 of the pump 14 can be frequency blocks 112 and 113, respectively, which, by changing the frequency of the three phase power supply of these motors, change the speed of rotation of the rotor, and thereby changing the performance of the pumps 9 and 14. Function of frequency blocks can also perform and thyristor blocks when performing pumps, or rather their DC motors, with the collector rotor. Modern automation techniques allow control of the speed of rotation of the motor rotor from the temperature sensor through the regulating device. In this case, the blocks 112 and 113 functionally related to the temperature sensors 114 and 115 through regulating devices 116 and 117, while the temperature sensors installed on the primary is contact tachometers, installed on the engines of these pumps and mechanically connected with their rotors. In addition, such detectors can be frequency sensors limit frequency functionally related to the frequency blocks 112 and 113. Sensor marginal productivity 118 of the pump 9, and sensor performance 119 pump 14 may be any of the above sensors, the frequency block 112 is functionally connected to the engine 110 of the pump 9 through the sensor marginal productivity 119 pump 14, for example the contacts 120 (Fig.26), in turn, the frequency block 113 is functionally connected to the engine 111 of the pump 14 through the sensor performance 118 pump 96, for example through its contacts 121. A similar connection can be carried out through a combination of speed or frequency knobs 122 unit 112, and the frequency 123 of the block 113, and the output of the regulating device, for example via a regulating device 116, in this case it is possible the inclusion in the scheme intermediate relay 124, electrically associated with managing their contacts 120 of the sensor marginal productivity 119 and contacts 121 of the sensor marginal productivity 118, by the locking pins 125. In this case, the switching contacts 126 and 127 are connected to the input 129 are intermediate relay contacts 124.

The inlet and outlet of the injection pump 1 in some particular case (Fig. 27) can be connected via the relief valve 130, and the input it is connected with the output of the pump 1, and the output, fault, with the input of the pump 1. The relief valve 130 performs the same functions as the control valve 3.

The heater 32 may be installed on the pipeline 20 recharge of cold water or at the outlet of the pressure tank 25, for example, the nozzle 54 is functionally related to the temperature sensor through the regulator installed at the outlet of the heater 32, i.e., after the heater 32 on the above mentioned pipelines and pipes.

The inlet and outlet of the circulation pump 29 (Fig. 28) can be connected via the relief valve 131, the input connected to the output of the pump 29, and the fault output from the pump inlet 29. Relief valve 131 performs the same function as the valve 60.

Pressure tank 25 creates a pressure, which is determined by the height of the column formed by the water level in the tank 25, and the connection point of the output of the tank 25, the pipeline 6. About this pressure and adjusts the pressure of the pump 1 by means of the valve 3 or the safety valve 130.

When performing prakticheski equally, in this case, the ejector 66 may be in the form of a narrowing device, consisting of a chamber 132 which is placed in aperture 133 which divides the camera on the positive and negative pressure, while negative cavity is located after the aperture 133, and zero cavity to the diaphragm 133. Minus the cavity chamber bypass pipe 67 with the installed control valve 68 is connected to the output of the consumer cold 19.

Given that the negative cavity of the chamber 132, the water pressure is less than the pipeline on which it is installed, it is natural part of water, warmed, with consumer cold 19 will go into minus cavity chamber 132, mixing with cold water, heated up to the required temperature, which supports the automation system described above.

The ejector 66 and more precisely the jet mixer can be installed not only on the main pipe 6, but the pipeline is fed with cold water from an external source, such as the pipe 20, or at the outlet of the tanks 25, or on the nozzle 54.

The circulating water system operates as follows.

Discusses a specific example of the circulating water system by distillation of alcohol. Ohliday, part of it is on tap 65 is supplied for domestic production, or for areas where cost-effective to use heated water with a temperature at the outlet dephlegmator apparatus is 65oC. Next delegatory water flows, in the particular case, pre-cooling, i.e., the air cooler 28, and with him in the buffer tank 45 from him the injection pump 1 is supplied to the next stage of cooling, such as air cooler 11. When this excess pressure venting valve 3, is executed normally closed, connecting the input and output of the pump 1, the membrane actuator 4 through which the pulse tube 7 is functionally connected with the output of the pump 1, for example with the cavity of the main pipe 6. Next delegatory water delivered to the second stage cooling. Water-water cooler 12, the cooling which occurs when using, for example, artesian water, which is supplied to the cooler 12 by pump 14 through the pipeline 13 is installed on the control valve 17, which is responsible jointly with the Executive mechanism 35, the temperature controller 36 and the temperature sensor 18, covering or opening the flow of artesian water, what about the valve 9, installed on the main pipe 6 to the cooler 12. The connection is carried out as follows. If cold artesian water enough, the valve 17 is not fully opened, and thus, limit switch 37, which indicates the end position of the valve 17, the full closure, did not work, and its normally closed contacts 43 unlock the connection of the outputs of the temperature controller 34 with a starting device of the actuator 33 of the valve 9, for example with magnetic actuator 44. If for any reason, such as failure of one of artesian pumps, cold artesian water is not enough for cooling dephlegmators water to the desired temperature, the valve 17 is opened completely, and trigger contacts 43, closing the circuit connection of the temperature controller 34 with the actuator 33. Signals from the temperature controller 34 to close the valve 9 begins to take place, given that it is connected to the regulator out of phase, i.e. when the valve 17 is opened, the valve 9 is closed. At the same time turns off the limit switch 39, signaling the complete closing of the valve 9, and its normally open contacts 42 disables the connection of the temperature controller 34 with the missile launcher will do the wire 6, the valve 9 thereby reduces its flow to the cooler 12 and thereby balances the amount of the coolant, artesian water. If the problem is resolved and cold artesian water enough, it starts to open the first valve 9 is fully opened it through the limit switch 39, contacts 42 connects to the temperature controller 34, the actuator 35, through the starting device - magnetic actuator 44, and the valve 17 begins to close until until cooled water reaches a preset value. Thus, the valves operate alternately, i.e., the valve 9 and the valve 17 are not at the same time, thereby giving the greatest efficiency.

On the other hand, if artesian water composition pure enough, given its partial use for domestic purposes, in this case, ecologically pure artesian water can directly be mixed with cooling water, for example dephlegmators water. For this purpose, and serves as an automatic mixer, for example a three-way valve 90, which changes the value on the main line 6, after the valve 90, heated dephlegmators water and cold artesian water, depending on the signal from dahoma on the return temperature of the circulating water. Similar functions are performed and the mixer, made in the form of two valves 93 and 94 or one of these two-way valves to maintain specified temperature return water by changing the ratio of the cooled water and artesian water. Protective device for deep-well pumps 14, such as a relief valve 15, or if the valve 17 is made of three-way and one of its channels connecting the inlet and outlet of the pumps 14, allows you to override valve 17 pipe 113, without prejudice to the operation of the pumps 14, because in case of excess pressure at the outlet of the pump 14 excess artesian water will automatically be grazed or fed back to the input of deep pumps 14.

In order to avoid simultaneous operation of the valves 17 and 9 use a smart relay 36, which is controlled using the contacts 38 full opening of the valve 17, i.e., the contacts of the limit switch 37 and contacts 40 full closing of the valve 9, i.e., the limit switch 39. The contact 40 puts on the lock relay 36 and contacts 38 it removes, in this case, the contacts 42 and 43 are relay contacts 36, and the contacts 41 are locking. Otherwise, the principle of the control valves 9 and 17 is the same as described above.

Consider the example of use as a backup device to compensate for the water pressure in the circulating system when it is fall and recharge the system with water from a source outside the system, such as city water. As the above compensator can be used pressure tank 25, in which dologin, the flow regulator dephlegmators water valve 9 starts to block the pipeline 6. Naturally the water pressure after the valve 9 will begin to fall, and it will remain stable, since the valve 3 will increase the passage of water from the output of the pump 1 on their sign, i.e., increasing the circulation of water at the lower ring. A drop in water pressure after the valve 9 in the main pipe 6 will cause the opening of valve 55, because when you open the valve 9 or the closed valve 47, the system water pressure in the main pipe 6 is supported by the regulating valve 3, which is configured so that the outlet pressure of the pump 1 and in the pipeline 6 to users of refrigeration 19 is equal to or somewhat higher than the pressure generated at the point of connection of a branch pipe 54 with the main pipe 6, and of course in this case, the check valve 55 is closed, because direct its direction from the pressure tank 25 to the main pipeline 6. Assuming that the pressure in the pipe 6 is decreased, the non-return valve 55 will immediately open, and through it from the pressure tank 25 will begin to flow in the main pipeline 6 water, as compensating the pressure loss and its amount in the main pipeline 6. This simple example can used the total effect of which is significantly higher than the effect of individual technical solutions.

If there is no manufacture pressure tank 25, it may be a reducing device that is installed on the pipe 20, for example made in the form of a valve 21, which is also regulated pressure, equal to or slightly larger than the nominal pressure in the pipe 6. Given that reducing device is a check valve, in nominal operation mode of water recycling systems it is closed if the pressure in the main pipeline begins to fall, then of course it opens and starts, as in the case of the pressure tank 25, to feed the system, as compensating the pressure drop water in it, and its quantity.

But in the winter, as a rule, the temperature of the city water below the target value of the circulating water, it is not excluded the possibility and cold circulating water. There is a need of heating, the simplest and most cost-effective way of arriving at the consumer 19 cold water, including preheating city water or heated circulating water before the consumer cold 19, it is heated warm water output from the consumer's cold 19, or delegating tank 64, or other cumulative capacity l 75, for example, plate heat exchanger, which is supplied through separate channels and heated water such as city water, through pipeline 20, or from the pressure tank 25, or with a reducing device, valve 21, or from the main pipeline 6 supercooled circulating water, or a mixture of supercooled working capital and city water, and gave her a cold heated in consumer 19 cold circulating water. If water-water heater be positioned slightly below the point from which is taken the heated circulating water, you don't need the extra pressure pumps, additional electricity costs. Moreover, this method allows you to pre-cool the heated water coming from the consumer cold 19 that will save a coolant, such as artesian water, when cooled in water-water coolant, or coolant in any other heat exchanger. Control valve installed on the pipeline to warm water helps to maintain with considerable accuracy the desired temperature of the return water to the consumer cold 19. The temperature sensor 80 sends a signal to the regulating device 79, which, acting on the actuator 78, OTKRYTOGO heater 75. Heated counter current of warm water with consumer 19 cold coming on them supercooled water, can be implemented and integrated in multiple locations, are pressurized water heaters 75, for example, at the outlet of the pressure tank 25, the secondary pipeline 20 and the main pipeline 6 before the consumer cold 19, for example dephlegmators devices.

Another relatively simple method of heating supercooled water is to install ejector 66, which can be installed on the secondary pipeline 20 cold water (Fig.20), the output pressure tanks 25 (Fig.21) or on the main pipeline 6. When installing the ejector 66 on the main pipeline 6 it through ejection, arising from the movement of the supercooled liquid on it, sucks a certain amount of heated fluid, for example dephlegmators water, the output of consumer cold 19, this number is determined by the regulating valve 68, the actuator 69 which responds to deviations of the set temperature after the ejector 66, in the main pipeline 6, receiving the signal from the temperature sensor 71 through regulating device 70.

Finally, the third method preheat purebites cold 19 circulation pump 29, the performance of which is stabilized by the pressure valve 60. The task of the circulation pump 29 is to maintain the temperature of the water in the consumer cold 19 by blending it with some piece of warm water, taken from the output of consumer cold 19, the accuracy of target temperature determines the control valve 30, functionally associated with the temperature sensor 31.

In this system may be used and the standard method of stabilizing the temperature of the water that enters the consumer cold 19 is a heater 32, mounted on the main pipe 6, or on the pipeline 20, or on the nozzle 54. This heater can be both steam and electric, and automated the water temperature at the outlet of the heater 32.

The cooling system can be performed in a multistage, for example water-to-water cooler 72 may consist of several sections, and between them is the cooler 73 (Fig. 10).

If artesian water is clean enough, you can directly mix the water with the reverse that will give the greatest efficiency water-to-water cooling. Automatic valve 90, for example, provides certain is connected with the temperature sensor 92.

In the case of automatic control cooling system circulating water will work as follows.

If cold coolant enough to cool the circulating water to the preset value, the relay 124 is turned off, and its normally closed contacts 128 connect the output of the regulating device 116 to the block 113, and the pump 14 operates with a certain nominal performance, and it relays 124, normally closed contacts 126 connect the generator frequency 122, exhibited at the forced frequency, and therefore the efficiency of the pump 9, to the frequency block 112. Low cold for cooling circulating water regulating unit 126 notifies the pump 14 to maximum performance, the sensor activates the marginal productivity 119, such as contacts tachometer, and their contacts 120 includes relay 124 which their contacts 125 is blocked, its normally open contacts 129 connect the unit limit frequency 123 to the frequency block 113 to maintain the device for maximum performance, the contacts 128 disables the input device 116 and contacts 127 connect it to the frequency block 112, the contacts 126 disabling it the frequency 122, and the device emperature chilled water leaving the chiller 12. And finally, if the reason for the lack of cold is resolved, it will reverse the process by which the sensor marginal productivity 118 at the maximum speed of the pump rotor 9 with its contacts 121 be removed from the lock relay 124, which will restore the original connection of the output device 116 and frequency knobs 122 and 123 to the frequency blocks 112 and 113. On the output side of the block 112 may be installed inverter to invert the signal from the device 116 with the purpose of obtaining a reverse action on frequency block 112, in comparison with the frequency block 113, i.e., the same signal frequency block 112 decreases, the frequency of the block 113 is increased.

You can use it for mixing artesian water and circulating the heated water and the change in performance of the pumps 14 and 1, for example, using the frequency blocks that control the speed of rotation of the rotor of the pump motor 14 and 1, or one of them, or complex, with the use of valves, similar to the examples of non-contact cooling artesian water through a cooler 12 heated circulating water.
