The present invention relates to a device for cooling a fluid medium and apparatus for dispensing chilled fluid. In particular, the present invention will be described and explained on the example of the apparatus for dispensing cooled beverages, for example devices for distribution of the water normally used to distribute chilled water or other chilled beverages.

Device for cooling a fluid medium adapted for use in apparatus for dispensing chilled fluid medium, in General, known from previously published applications of applicant: EP 1129024 and US 6442960. Such devices typically includes a primary heat exchanger and secondary heat exchanger where the coolant is cooled in the primary heat exchanger. Such devices also contain the pipeline for the flow of fluid, which circulates fluid to be distributed after cooling. Such cooling is produced by introducing pipeline, which is subject to the distribution of fluid in direct or indirect contact with the fluid, previously cooled in the primary heat exchanger.

One of the disadvantages of the known devices is that the primary and secondary heat exchangers must be very large, so they had the ability to cool the liquid in the desired range. is what limits their use in apparatus for dispensing chilled fluid medium, which, in turn, result in a very bulky and expensive operation, cleaning or sterilization and maintenance, and downtime during cleaning or sterilization relatively long.

Therefore, to eliminate the above disadvantages of the objectives of the claimed invention is to provide a device for cooling a fluid medium with a reduced volume of such devices while maintaining the same or equivalent cooling efficiency and easier maintenance, i.e. cleaning methods or sterilization, devices, and accordingly the apparatus for distribution, which is mounted such devices.

This opens the way for the use of such devices for cooling a fluid medium and apparatus for distribution in other areas where they had not previously used or their use was not economically feasible, for example, for the distribution of chilled fluid in the gas phase, and also to enable the transportation of such chilled fluid on sterilized circuit, for example, in a personal or domestic apparatus for supplying oxygen to support breathing.

To solve the above problems created by the device for cooling a fluid medium that is designed, for example, for distribution, or distribution of chilled fluid among the s, comprising: a primary heat exchanger; a secondary heat exchanger; a first pipeline, which circulates the cooled fluid and the heat transfer medium to transfer the cooling energy of the cooled fluid circulating in the first pipeline; where the primary and secondary heat exchangers are placed at least partially within one another.

Also created a device for dispensing chilled fluid medium containing a device for cooling a fluid medium, described above.

Another object of the invention is a method of sterilization of the device for cooling a fluid medium and apparatus for dispensing chilled fluid medium.

More specifically, because the present invention was able to reduce the volume of circulating fluid, and preferably the amount of the produced fluid in the solid phase. This reduces the overall size of the device for cooling a fluid medium and, accordingly, the dimensions of the apparatus for the distribution of chilled fluid medium in which it is mounted. It should be noted that the device for cooling fluid according to the present invention does not have to contain a primary source of heat in the primary heat exchanger, as described in the earlier application of the applicant. In addition, the process of heat transfer significantly improved instown through the device, proposed in the present invention.

Therefore, one advantage of the present invention is that the device for cooling a fluid medium may be mounted in any apparatus for dispensing chilled fluid medium, for example in apparatus for dispensing drinking water.

In addition, the device for cooling the fluid does not need to contain the drain pump when not required sterilization device for cooling a fluid medium or apparatus for dispensing chilled fluid. The pump may be included in the device if desired sterilization of the circuit containing the first pipeline, for example, in the apparatus for the distribution of drinking water or for distribution of oxygen in the device for the auxiliary breathing.

In a more preferred embodiment of the invention the first heat exchanger is at least partially, and more preferably essentially within the secondary heat exchanger. Under the words "partially inside" or "being inside" here understand that at least part, and preferably a large part of the primary heat exchanger in relation to space is located within the secondary heat exchanger. This enables the creation of very compact devices for cooling fluid is Reda according to the invention and reduce the volume of coolant, which circulates through the circuit to achieve the desired cooling effect.

In one preferred embodiment of the present invention, the primary heat exchanger contains a camera. The camera is usually made of plastic or metal, so that it is not deformed or does not lose shape under the influence of the operating temperature or pressure, in particular under the influence of the generated low temperatures, and it may generally cylindrical shape, although specialists in this area can be easily offered, and other forms that will be consistent with its functions. The camera gives such dimensions that it was possible to arrange the coil is used to provide heat exchange with a coolant for cooling in the chamber of the primary heat exchanger. It should be noted that instead of the coil can be used and other means of achieving a cooling effect, for example, using a finger and electrothermal Peltier effect, or equivalent means. Preferably, the primary heat exchanger also had thermostat, whereby it is possible to adjust the temperature of the coolant, thereby controlling the volume of the solid phase carrier, which is formed in the chamber. In this application and in the claims are used interchangeably, the terms "agent for transferring the heat" and "agent for exchange of heat", the meaning of which is defined below. The terms "agent for heat transfer" or "agent for heat exchange" means the agent, whereby it is possible to effectively transfer its thermal energy to the fluid to be cooled and to distribute, preferably without having the initial message of energy. Preferred fluids are those that are easily convertible from liquid to solid phase and Vice versa. Water is the preferred coolant, as the ice formed by the coil in contact with water coil in the chamber, seeking only to the slow melting, thus freeing up the cooling energy over time, and only requires minimal energy input at the start. In addition, the use of water as a coolant allows the circulation along the contour of the suspension of ice and water, to provide greater efficiency of energy transfer, if the need increases. Of course, you can also use other well-known carriers, for example, halocarbons, such as perchlorate or hydrogeologist; solutions or dispersions, which are involved in the endothermic reaction by adding or removing water or other solvent; gaseous fluids, for example, ammonia, or any of those is lnositol, which engage in an endothermic reaction; and similar substances that cause heat the fluid to be cooled. Other suitable coolants include monoethylene glycol, monopropylene and anti-corrosion agents containing salt water.

In a preferred embodiment, the coolant circulates in the chamber of the primary heat exchanger and between/and around the coil that is installed in order to take away heat from the coolant as the coolant using the water, causing the transition of a liquid partially in the solid phase and turning into ice. Such a system generally known as the "battery of ice". The volume of ice regulate by means of a thermostat, which accordingly is located inside the chamber, for example, inside the periphery bounded by the coil, or in an alternative embodiment, thermostat may be placed in the camera in a different location, depending on the degree of accuracy required to regulate the amount of coolant passing into the solid phase.

The volume of fluid in the chamber of the primary heat exchanger is such that at the transition from the liquid phase to the solid phase or from the gaseous phase to the solid phase the remaining uncured, but chilled fluid is moved from the chamber of the primary heat exchanger in the chamber of the secondary heat exchanger. Roaming refrigerated liquid or gaseous coolant then flows over the first pipeline, as described above, and when it is in contact with the first pipeline, which convey the fluid to be cooled, is heated and is forced through the issue made from the other side of the camera, in the secondary heat exchanger. Thus fluid or circulating in the first pipeline is cooled.

In an alternative preferred embodiment, the primary heat exchanger contains a separate coil and chamber for transferring cooling energy of the heat carrier at a distance from the second pipeline. In other words, the primary heat exchanger contains a single node transmission energy for cooling of the heat carrier at a distance from the second pipe secondary heat exchanger. In this case, the primary heat exchanger also includes a thermostat for regulating the temperature of the coolant and, therefore, the fluid to be cooled. As defined in this application and in the claims, the term "thermostat" here understand electronic or Electromechanical sensors or detectors temperature or, for example, the bimetallic plate. More preferably, the primary heat exchanger also contained a pump connected to the chamber of the primary heat exchanger. With the help of the pump is facilitated by the process of the coolant in the secondary HEA is. The chamber of the primary heat exchanger may be connected to the second pipeline of the primary heat exchanger through the issuance coming from the said chamber to the second pipeline. The flow of coolant to the second pipeline can also lead a counter-current relative to the flow of the fluid to be cooled, circulating in the first pipeline.

It may be desirable, as mentioned above, the sterilization device for cooling the fluid. For this choice is preferable to the primary heat exchanger also contained a reservoir or tank for recovery of the heat carrier.

In particular, the device for distribution to ohla the established fluid medium preferably further comprises another handout crane, connected to a source of fluid regardless of the above-mentioned device for cooling the fluid. The second transfer valve normally distribute the fluid, which is not cooled, i.e. it connects directly with the source of fluid. This may be applicable, for example, in the apparatus for dispensing fluid, such as water distribution, where the consumer may be offered the choice of receiving chilled drinking water through a single dispensing faucet and water at room temperature or heated water through another handout crane. Preferably, the source of fluid to be cooled and to distribute, was removable, and more preferred would be the ability to select from a group comprising a bottle, a canister or tank, or are not under internal pressure.

Detailed description of the invention

Example 1

Device for cooling the fluid, indicated in General position 1 represents a machine with an ice battery cold. The device 1 includes a primary heat exchanger, indicated in General position 2, and the secondary heat exchanger, indicated in General position 3. Primary and secondary heat exchangers 2, 3 contain (each) camera 4, 5, respectively. Chambers 4, 5 are made of plastic. The camera 4 of the primary heat exchanger 2 includes an evaporator or cooling coil 6, which is connected with a standard refrigeration unit (not shown), on th the th outside of the primary 2 and secondary 3 heat exchangers. As shown in figures 1 and 2, the camera 4 is partially placed inside the chamber 5. Camera 4 and 5 preferably have in total a cylindrical shape. The primary heat exchanger 2 also contains thermostat 7, as mentioned above, designed to regulate the temperature of the heat carrier 8, in this case, the water contained in the chamber 4. In the chamber 4 ice used as a heat transfer agent 8 (solid phase), get through the evaporator or coil 6. The volume of ice 8 regulate by means of thermostat 7, located in the chamber near the evaporator or coil 6.

In the secondary heat exchanger 3 in the chamber 5 is the first pipe 9 in the form of a coil of stainless steel, which is fed into the fluid medium 10 to be cooled, in this case the drinking water out of the bottle (not shown) and nozzle (not shown). In an alternative embodiment, the fluid to be cooled, can be obtained by direct attachment device for cooling fluid to the power supply of a fluid medium, such as a crane network of drinking water. Any increase in temperature of drinking water 10 inside the first pipe 9 is determined using the second thermostat 11, located in the second chamber 5 near the pipeline 9. The pump 12 is activated via this second thermostat 11, and the warm coolant 8, in the case of water, is drawn from the second chamber 5 through issue 24 and is pumped into the first chamber 4. This warm coolant 8 replace the cold coolant from the first chamber 4 through the release of 16. The carrier 8 reject using deflecting plate 13 when it entered into the first chamber 4 to allow contact of the fluid 8 flowing from the second chamber 5, with the coolant being in the solid phase, i.e. ice battery, to maintain the temperature of the heat carrier 8 in the second chamber 5 at a low enough level. The temperature of the fluid medium 10 to be cooled, in this case water, inside the first pipe 9 is thus reduced to the desired level. As shown in figures 1 and 2, a large part of the first pipe 9 is immersed in the cooling fluid 8 in the second chamber 5 of the secondary heat exchanger 3.

One of the most effective ways of cleaning device for cooling the fluid heats the entire pipeline, used for passing drinking water. This method is also good for the environment because it does not use any chemicals.

In the method according to the present invention, an electrical current is used to heat the entire system of stainless steel pipes, which contain the fluid, which over IIT cool. The method includes the use of electrical resistance (not shown)which is attached to the power transformer (not shown). Current large forces, for example 80 And, at low voltage, for example 7.1 In, passes through the secondary circuit of the transformer and the resistance. Resistance heated by the current passing through it. It is clear that the person skilled in the art can choose the voltage and amperage so that they match the materials used in the circuit of a cooling fluid, and available surface area. The temperature is determined by the length of the time period during which current is passed through the resistance. The greater the length of the time period, the higher the temperature. In this way the electrical resistance comprises resistance stainless steel pipe, representing the first pipe 9, at the option of the punch 14 and a part of the air circuit containing an air filter 15, i.e. the drinking water system. The choice of valves can also be part of the path. All these parts are interconnected by welding or soldering to ensure a good and continuous electrical conductivity. The sizes of these parts are picked so as to obtain the required electrical resistance. Device for cooling a fluid medium connected to electric is to the transformer, outside the primary 2 and secondary 3 heat exchangers, copper wires, or other suitable materials, which connects the two plates welded to the device for cooling the fluid. The first connection is made with the pipe 15, through which provide for the passage of air into the device, and the second with the first pipe 9 just before the faucet. Also provide a shunt connection at various points in the circuit to complete an electrical circuit and to obtain the maximum heating effect. The power transformer may, for example, be 400 watts, but it should be adjusted in accordance with the materials used, usually in the range 200-500 watts.

For sterilization using the described apparatus, the device 1 for cooling fluid is also equipped with a second pump 17, a reservoir 18 for recovery or storage of the coolant pipe 19, which connect the second pump 17 with the reservoir 18 for storage, and release of 21 for the message pump chamber 5 through 24 issue. The storage tank also includes a tube 20 containing the filter-valve for relieving excess pressure occurring in the device due to the formation of a solid phase carrier 8 in the chamber 4. Before sterilization of the pump 12 by choice is stopped and the pump 17 to include the otso is as fluid 8 from the chamber 5 through 24 editions and 21 through the pipe 19 into the reservoir 18 for storage. After removal of the carrier 8 from the chamber 4 remove the source of fluid, and all of the fluid to be cooled, remaining in the first pipe 9, or remove from the device through the pipe 23 which leads to a nozzle (not shown), if there is a pump for air, or by heating loop. If you have a pump for air, the purpose of which is to reduce the period of time required for sterilization, may be filed with the electric current, as described above, which leads to heating of the first pipe 9 and, in turn, to heat any drops of fluid remaining in the first pipe 9, causing the formation of steam or very hot air. The temperature of this gas or vapor sufficient to sterilize the loop and destroy any bacteriological infection. After sterilization device for cooling the fluid insert a new source of fluid, a second pump 17 is stopped and the coolant 8 release down under its own weight from the tank 18 for storing the pipe 19 through the pump and releases 21 and 24 into the chamber 5. After returning coolant 8 back into the chamber 5, the pump 12 can be re-enabled (it was previously disabled) and device for cooling a fluid medium may be again put into operation. The second pump 17, the tank 18 for storing soedinitelnoj pipe and releases 24 and 21 helps that reduced downtime, because they accelerate the draining and re-filling the chamber 5.

The only difference between the version presented in figure 2, from the version presented in figure 1, is that the version presented on Figure 2, does not contain the second pump 17, the tank 18 for storing or connecting pipes. Device for cooling a fluid medium must, however, have editions of 24 and 21 closed by a stopper 25, which carry out the draining and re-filling the chamber 5 manually that you want to reseed manually after each operation for sterilization.

Example 2

Device for cooling a fluid medium, are presented in figure 3 and 4 and indicated in General by position 101, contains a primary heat exchanger, indicated in General position 102, the secondary heat exchanger, indicated in General position 103, and the reservoir 118 that serves as a reservoir or storage containers for the Gulf of pump 112 through a pipe 127 coolant 108, and as a recovery site for the same carrier 108.

The primary heat exchanger 102, in which the cooling fluid includes a reservoir or chamber 104 containing the heat transfer medium 108, which may be either in the form of a fluid or solid phase around the coil (not shown) or the finger, or other equivalent means known to the experts in this field, but essentially the same as described relative to a preferred variant, illustrated in figures 1 and 2. The coil in this case is made of a suitable material, the use of which enables an efficient transfer of energy from the coil to the primary coolant, and preferably it is made of metal, such as copper, so that the fluid 108 to move from a phase of the fluid to the solid phase and Vice versa. The volume of the solid phase carrier 108 in the chamber 104 of the primary heat exchanger regulate by means of a thermostat or equivalent means, well known to experts in this field, and as described with reference to figures 1 and 2. Thermostat, therefore, is the instrument through which start and stop the cooling process.

The secondary heat exchanger 103 contains the first pipe 109, inside of which circulates fluid to be distributed, for example a beverage, such as drinking water. The second pipe 126 has a larger diameter than the first pipe 109, passes together with the first pipe 109 and around him, at least along part of the length of the first pipe 109. In the second pipe 126 contains the coolant 108 commenced the traveler from the primary heat exchanger 102. The second pipe 126 is located around the pipeline along its length so that a sufficient amount of cooling energy was transferred from the coolant 108 cooled fluid that circulates in the pipe 109. The second pipe 126 passes coaxially along essentially the entire length of the first pipe 109. As shown in figure 3 and 4, two pipe 109, 126 form a General spiral configuration of the coil 131.

Two heat exchanger 102, 103 are combined in the circuit through the reservoir 118 serving as a backup tank and tank Bay pump, with the pump 112 perform circulation 108 between the primary heat exchanger 102 and the secondary heat exchanger 103.

The temperature of the secondary heat exchanger indirectly regulate by means of a thermostat located in the first heat exchanger 102, or by using equivalent means which regulate the operation of the pump 112. Preferably, thermostat is set so that through him turn on the pump 112, once the fluid begins to leak from any of nozzle 128, 129. Regulation through thermostat action of the secondary heat exchanger 103 is also used to maintain a predetermined temperature of the fluid to be distributed.

The agent 108 to transfer the heat (tepano Italy), or agent for heat transfer (heat transfer medium), can also be retained in the reservoir 118 for optional cleaning apparatus. During cleaning or sterilization of the first pipeline 109 containing the fluid to be distributed, produce plums agent 108 for heat transfer (heat carrier), which can be done by opening the Electromechanical valve 130 that is included with the switch, or similar device. By means of the Electromechanical valve 130 sets the highest point in the first pipeline 109 at the same pressure, which is created in the reservoir 118 and the carrier 108 then flows to the reservoir 118 through the pipe 131, and after sterilization can be transferred by a pump to a heat exchanger 102 through the pipes 132 and 133. At this point, the pump 112 is turned off. Sterilization can be done in several ways. One way is to perform the selection by removing the source of fluid to be cooled and to distribute, opening distributing valves 128, 129 and washing the first pipeline sterilizing solution, such as solution of sulfamic acid. When this process also removes scum. In a particular preferred embodiment, however, the fluid from the second pipe 126 is drained into the reservoir 118, as described above, and then may also be the lita fluid from the first pipe 109, for example, by opening the dispense valves 128, 129, leaving only traces of the fluid to be distributed. The first pipe 109 may then be sterilized by supply of electric current, as described with reference to a variant, illustrated in figure 1 and described in Example 1. This electric current, which heats the material of the pipeline, causing heating of the traces of the fluid or any number of fluid still remaining in the first pipeline, and by alternately blocking and included in the intake pipe, for example, using cups, and transfer valves 128, 129, at appropriate times, you can force generated hot steam to go down the path from the inlet to the transfer valves 128, 129, thus sterilizing the pipe 129. Complete sterilization of the pipeline 109 can be achieved by passing an electric current for a sufficient period of time to heat the traces of the fluid to a temperature sufficient to destroy a significant number of bacteria present in the pipe 109, and bring to a level that satisfies any requirements of hygiene. In General, complete sterilization can be achieved by heating the device, as described above, for approximately 210 minutes, and on the selection and greater period of time.

After completion of the sterilization fluid 108 may be again filled in the primary and secondary heat exchangers 102 and 103 through the closing of the Electromechanical valve 130 and re-enable the pump 118.

An alternative version of this method may be obtained by introduction of the tank, and only incomplete filling of the primary heat exchanger 102 of the carrier 108. When it is desirable to carry out the sterilization of piping 109, from the secondary heat exchanger 103 remove the coolant 108 off of the pump, resulting in fluid 108 flows by gravity to the primary heat exchanger 102. Thus, when the pump 112 is switched off by thermostat, the remaining fluid 108 in the second pipeline 127 automatically merges under its own weight, after which you can carry out the sterilization of piping 109, as described above. At this time you can use the first pipe 109 for the supply and distribution of fluid at room temperature, if desired.
