Description

Description of the invention

A utility model relates to the creation of systems or lines used for cooling and 2 bottling beverages. As a rule, such lines are installed in cafes, bars, restaurants and other trade and public catering enterprises for cooling and bottling drinks, including beer that is in kegs.

Many different devices and systems for cooling and bottling keg beer are known. One of such well-known systems is the RKE-MIX (PRE-MIX) system, the essence of which is that for the operation of such a system a semi-finished beverage product is used, in this case beer from kegs, which must be saturated before bringing it to readiness for consumption carbon dioxide (carbonation process) and cool to the temperature at which it needs to be bottled, that is: from b to 1092C, and the temperature, in turn, depends on the type of beer. Similar systems are divided into over-racks, which are above the rack for pouring beer, and under-racks, which are under the rack.

The set of over-standing equipment of such a system has small overall dimensions, and the productivity of this system is from 10 to 35 liters per hour of one or two grades, less often - three grades of beer. Stand systems for cooling and bottling beer are more expensive and their productivity can be from 25 liters to 250 liters per hour, and the number of types of beer can be from two to fourteen types.

It is also known that many bars and other similar establishments have beer distribution systems. Of course, beer is stored in barrels - kegs, which are located in a large cooling chamber or a small refrigerating chamber.

The dispensing columns are connected to one or more beer lines, which are combined into one or more beer distribution hoses, depending on the brand numbers or types of beer. Beer distribution hoses run from the cooler to the distribution elements. Each beer hose for dispensing beer must be connected to a delivery system that distributes the brand or type of beer to the various dispensers located in the bar. In addition to the beer distribution hoses, one or more cooling hoses usually run along the beer distribution hoses from the cooling chamber to the final beer distribution point. These cooling hoses are usually located next to the beer dispensing hoses and can sometimes be shaped like a ring or spiral around the beer dispensing hoses. The cooling hoses are designed to keep the beer chilled as it is delivered from the kegs to the cooling chamber in the beer distribution tower. at

It is known that beer coolers are divided into two types - water cooling, they are also called (Te) flow-type coolers and dry cooling. In the first type of beer cooler, water is poured into the tub and cooled using a compressor. Coils are immersed in the water bath along which the beer "runs", and a pump that takes cold water and carries it through a separate pipeline, which runs parallel to the pipeline with beer. Thus, the beer will be accompanied by a pipeline with cold water to the tap itself and

Zo is poured cold. This system is called "python". In "dry type" beer coolers, the bath, where the beer lines and the cooling circuit are located, is filled with a special gel or aluminum. "Dry type" beer coolers come into working mode faster, you can work 7-10 minutes after switching on, "water cooler" takes about an hour to reach the required capacity, but they are much more expensive than "water coolers" - apparently this explains why "dry type" beer coolers are rarely used. Equipment for cooling and bottling beer is designed for at least 6-8 years with constant technical and technological maintenance of this equipment. The productivity of the cooler can be from 3 to 180 liters per hour. The most popular for "roll-bars" are beer coolers for two types of beer, with a capacity of 10 liters per hour. Special large coolers "TKORIS" have been developed for regions where the air temperature in summer exceeds ЗО 9С and the throughput capacity of the trading point is quite high. 15 Known, for example, "DEVICE FOR COOLING A LIQUID ENVIRONMENT AND APPARATUS FOR DISPENSING COOLED LIQUID ENVIRONMENT, WHICH CONTAINS SUCH A DEVICE AND A METHOD FOR ITS STERILIZATION" (see application RF Mo 2005122473 dated 2007.01.27). According to the proposed technical solution, the device for cooling of the fluid medium for distribution or distribution of the cooled fluid and 50 medium, which contains: the primary heat exchanger; the secondary heat exchanger; the first pipeline through which

Ge") circulates a cooled fluid medium; coolant for transferring cooling energy to the cooled fluid circulating in the first pipeline; and the primary and secondary heat exchangers are located at least partially one inside the other.

The proposed technical device can be used for cooling drinks, including beer, however, the proposed technical device has a number of significant drawbacks. The proposed "DEVICE FOR COOLING 59 LIQUID ENVIRONMENT AND APPARATUS FOR DISTRIBUTION OF COOLED LIQUID ENVIRONMENT, CONTAINING SUCH DEVICE AND METHOD OF ITS STERILIZATION" is structurally complex, which can be reflected in the performance of installation work in small bars or restaurants. The difficulty of mounting the proposed device is that the device cannot be mounted in small bars or restaurants, which do not have enough space to accommodate all the technological equipment. In addition, despite the fact that the device is quite complex and bulky, it cannot provide cooling of the beer during its movement along the beer hose, and also does not provide the possibility of changing the length of the beer hose during start-up and adjustment works. When installing the proposed device, the length of the beer hose is precisely calculated when drawing up the technical project, and in the event of a change in this length, additional design and construction calculations have to be performed. because the technical solution of the international application "Linear amplifier of the beverage distribution system" (see

MUO/2004/16545 dated 26.02.2004, Applicant: ISEE'OE TESNMOHOSIEZ IMS. |СА/САЙ;)). According to this technical solution, the proposed system for cooling and bottling drinks includes: - source of drink; - at least one drink distribution element; - at least one distribution wire for delivering the beverage from the beverage source to the distribution element, wherein the heat transfer element is located separately from the beverage source for immersing at least the distribution wire in the cooling bath. 70 The heat transfer element prevents the heating of a drink, such as beer, which occurs as a result of laying distribution beer pipelines over long distances. In addition, the heat transfer element in the standby state includes a chamber that determines the capacity. The first inlet pipe is made to introduce the coolant into the chamber. The first inlet and the first outlet pipes are not connected inside the chamber so that the coolant can accumulate in the volume.

The second pipe is located in the chamber and includes inlet and outlet holes located on the surface of the chamber.

A second pipe is pushed through the entire volume in order to separate it from the coolant in the chamber.

Also, the system includes a heat transfer element for the beverage distribution system, in which the source of the beverage is located at a distance from the beverage distribution element and is delivered to the same by means of the distribution beer pipeline.

This technical solution applies both to beer distribution systems and to devices for its cooling, which are installed in bars and are able not only to cool the drink, but also to reduce its ability to form foam during pouring.

However, the proposed technical device also has a number of significant technical shortcomings. According to the authors of the proposed technical solution, it is able to maintain the beer temperature at the outlet of the tap at about 282E (which corresponds to -2.222C), which is only the middle of the beer cooling temperature range (from -592C to -0.52C) for the technical solution, which is declared However, since the temperature of the coolant in the proposed device (according to the application M/O/2004/16545 dated 26.02.2004) is 32-34 РЕ (0-141)2С), it is not entirely clear how the declared temperature can be achieved of beer at the exit from the pouring column - about 289E (which corresponds to - 2.222). In addition, according to the authors of the proposed technical solution (according to the application (o)

MO/2004/16545 dated 26.02.2004), the beer temperature at the exit from the bottling column is - about 28 "E (which corresponds to - 2.222С), but according to, for example, the technical decision "THE METHOD OF MANUFACTURING SPECIAL

"BALTIKA MEDOVE KREPKOE" BEERS (see RF Patent No. 2186841), according to which "finished beer before (22) lightening by filtering through kieselguhr, is lightened on separators followed by deep cooling to (-0.5) - (-3) 2С...... In addition, the temperature of beer cooling down to (-3)2С is also found in

Other sources of information and security documents. In addition, it is also known about the temperature from beer cooling to (-4)2С. Thus, it is quite obvious that beer does not have a constant Sopviapi freezing temperature of -282Е (or - 2.222С) as recorded in the application MUO/2004/16545 dated 26.02.2004, and the freezing temperature of this drink depends on its composition, density and other technological indicators, which are determined by the type of /-«f beer. 70 Thus, the reason for the creation of the keg beer cooling and bottling line was the following reasons. in c 1. Traditional beer coolers of the "flow-through" or, as they are also called, "wet type" have rather unsatisfactory stability of product temperature maintenance at the exit from the cooler. The stability of temperature maintenance in such coolers directly depends on the depletion of the collected ice bank, i.e. as depletion of the ice accumulated by the cooler - the temperature of the beer at the outlet of the cooler increases. 75 А to restore the depleted ice, a rather long time of 40 minutes or more is required, which, in turn, again has an unsatisfactory effect on the stability of maintaining the temperature of the product at the outlet. Dry blocks (Те) devices that are offered as beer coolers have a fairly accurate temperature support of the aluminum "dry block" and a fast recovery time. These indicators have a positive effect on the stability of the support and the output temperature of the product. b 50 2. Traditional coolers are made in two common versions: standing and ultra-resistant, and all of them, like pr Avilo, equipped with air condensers. In this design of the beer cooling line, it is proposed to use a "dry block cooler" with the dimensions of an over-rack small cooler, but it will be placed as an under-rack, which will allow more rational use and save important space of the bar counter and the space under it. Moreover, the cooler designed for up to 59 degrees of beer cooling is equipped with a water condenser. This allows you to avoid unnecessary heat emissions under or on the bar counter, which, as a rule, is created by the air condenser of traditional coolers. Excess heat is created by the air condenser of traditional coolers, which in turn, as a rule, creates discomfort for the bartender and visitors by heating the temperature of the air surrounding the bar. This is especially noticeable in the summer season. The heated air surrounding the bar is unlikely to have a positive effect on the operation of other bar equipment: juice cooler, ice generator, etc.

In addition, the water condenser allows you to organize a more stable cooling cycle of the cooler.

The operation of any refrigerating machine depends on the ambient temperature. Any condenser of a refrigerating machine is a heat-releasing element of the refrigerating circuit, so it must be cooled. But in one case, it is cooled due to the circulation of the surrounding air, which is organized by the condenser fan, then it is called an "air condenser". | if the temperature of the ambient air at the inlet to the condenser is high enough, for example, in the summer period, the cooling of the condenser will be insufficient, as a result of which the performance of the refrigerating machine will decrease.

Therefore, the purpose of the proposed technical solution is to create a keg beer cooling and bottling line, which

It can provide cooling of beer during its movement through the beer pipeline, as well as a stable temperature in the range from -592С to -0.52С, at the exit from the bottling column.

The basis for the creation of a technical solution is the task of improving the cooling and bottling line of ket beer, according to which the cooling and bottling line of ket beer includes a pouring column, a connecting beer pipeline, made in the form of a python hose, a chamber for storing ket beer, necessary and 7/ 0 a sufficient number of kegs with beer, the main cooling device (SV - 2005 ROGAK), a pump for coolant, according to the useful model, the keg beer cooling and bottling line additionally contains an additional cooling device (SV - 2000 ROI AK), which is included in the general cooling circuit and bottling keg beer, in such a way that the cooling of the water condenser of the additional cooling device is carried out with the help of propylene glycol, the required temperature of which is maintained by the main 75 cooling device (SV - 2005 ROGAK), and the supply of propylene glycol to the water condenser of the additional cooling device (SV - 2000 ROGAK ), regulated by d with the help of a water control valve (VRV), in addition, the main cooling device (SV - 20005 RO|HAK), contains a capacity for propylene glycol, the main cooling device (SV - 2000 ROGAK), contains a brazed plate heat exchanger of the cooler, which is filled with the required amount of freon using thermoregulating 20 valve (TRV), an additional cooling device (SV - 2000 ROGAK), contains a freon condenser of water cooling, in which a water regulating valve (VRV) is used to maintain a constant condensation temperature, the connecting beer pipeline is made with the possibility of triple and more circulation coolant along the entire length of the beer pipeline.

The novelty of the proposed technical solution lies in the fact that, unlike traditional keg beer cooling and bottling lines, according to the proposed technical solution, the proposed keg beer cooling and bottling line contains an auxiliary cooling device (SV - 2000 ROG AK), From which it is included in the general circuit of cooling and bottling keg beer. The cooling of the water condenser of the additional cooling device is carried out with the help of propylene glycol, the required temperature of which is maintained by the main cooling device (SV - 2000 ROG AK), and the supply of propylene glycol in Teh! 30 The water condenser of the auxiliary cooling device (SV - 2000 ROGGAK) is regulated with the help of a water control valve (WQV), which as a result allows not only to reduce the temperature at the outlet of the pouring column from -52С to -0.52С, but also to ensure pouring beer up to 212 l/h in a continuous mode of pouring Fo into glasses for 15 minutes, and in addition, the presence of a water control valve (WQV) will allow directly during installation work to adjust the supply of coolant (22 35 (propylene glycol) to the water condenser of the additional device cooling (I SV - 2000 ROG AK), the amount of coolant (propylene glycol) depends on the length of the beer pipeline.

The inventive level of the claimed technical solution consists in the fact that the presence of an additional cooling device contributes to the additional cooling of the main circuit of the cooling system and its individual devices, which contributes to the solution of the technical problem, namely obtaining at the exit from the "470 bottling column beer with temperature from -52C to -0.59C, depending on the type of beer. 2 s. According to the proposed technical solution, the cooling and bottling line for ket beer allows beer to be cooled to a temperature at the exit from the bottling column from -592С to -0.52С, while beer bottling can be 212 l/h in continuous bottling mode in glasses for 15 minutes. This means that the line allows you to pour one keg of beer in minutes, maintaining the temperature of the beer that is poured into the glasses in the range from -59 C to -0.59 C. The operating mode of the laziness is designed for three quarters of an hour of continuous beer pouring, which alternates with a five-minute recovery of the line, during which no bottling is carried out. Let's consider the operation mode of the line in more detail.

It is supplied with a maximum continuous product flow of 212 l/h, which is cooled in the line to (se) temperature from -59C to -0.52C and this mode of operation lasts 15 minutes. This operating mode of the line is called - b 20 operating mode. After 15 minutes, a keg of beer was poured and cooled through the line. Then, the continuous filling is stopped by closing the filling valve on the column, and the line returns to its original position, (12) i.e. it is restored, and is ready for the next operating mode. This mode of the line is called recovery mode, and this mode lasts for 5 minutes. Then, when the recovery mode of the line has passed, the continuous flow of the product begins again and its cooling is carried out, thereby starting the next cooling cycle. By the cooling cycle, we understand the time during which the line performed the operating and recovery modes. Beer that is served in the line must be stored in kegs that are located in a refrigerated room or a special refrigerating chamber where the air temperature is maintained at 3,520. In these storage chambers, beer in kegs is pre-cooled to a temperature of 3.52C, after which it is served to the line. As a rule, almost all beer restaurants, large bars, cafes, etc., are equipped with such hidden cameras, and the appearance of the hidden camera 60 is shown in Fig. 1.

In Fig. 2 schematically shows the beer cooling line designed by us. It can be seen from the scheme that the beer is fed to the heat exchange unit 3 for bottling, through the python hose, and the propylene glycol cooled in the heat exchanger 9 is brought here, thereby maintaining a constant temperature of the beer that enters the heat exchange unit 3 for subcooling. In the proposed cooling line of beer, it is planned to use two coolers, this is the cooler I SV - 2000 ROI AK, and the cooler I SV - 2000 ROG AK.

The scheme of the bottling and cooling line of Ket beer (Fig. 2) consists of the following structural elements: 1 - beer kegs; 2 - python; C - heat exchange unit of the cooler of the "SV - 2000 ROGAK" LOP, 4 - filling column; 5 - water condenser of the ROP cooler "I SV - 2000 ROG AK"; 6 - water regulating valve (WWV); 7 - pump for propylene glycol; 8 - the capacity for propylene glycol of the cooler "I SV - 20005 ROI AK"; 9 - brazed plate heat exchanger of the cooler LOP OL/SV - 20005 ROGAK"; 10 - air condenser of the cooler LOP SV - 20005 ROGAK".

The task of the cooler I SV - 20005 ROI AK includes the cooling of propylene glycol, which is carried out as follows. Cooled in the heat exchanger 9, the propylene glycol, under the pressure difference created by the pump 7, flows into the capacity 8. Further, with the help of the same pump 7, the propylene glycol from the capacity 8 flows into the python hose 2.

Then, the propylene glycol, leaving the piton 2, passes through the tee into the heat exchange unit 3, and from the heat exchange unit C returns to the heat exchanger 9 for cooling. The cooling of the propylene glycol in the heat exchanger 9 takes place with the help of a refrigerating machine, which is part of the cooler I SV - 2000 ROGAK .

Propylene glycol, circulating through the system, performs several functions. Its first function is to maintain the temperature of the beer supplied for bottling through the python hose 2. This is achieved as follows. The beer served from keg 1, at a temperature of 4.59C, enters hose-python 2. Propylene glycol, cooled in heat exchanger 9 to a temperature of -392C, is introduced here into hose-python. Thus, as a result of the heat exchange between the propylene glycol with a low temperature and the beer with a plus temperature, there is a maintenance and 2o cooling of the beer that passes through the python hose. This means that the temperature of the beer at the exit from the python hose 2 will be equal to or lower than the temperature at its entrance. If the temperature of beer at the entrance to the python hose is equal to 4.52C, then at the exit it should not be higher than this temperature, which is achieved by triple circulation of propylene glycol through the python hose. Triple circulation means that propylene glycol passes through the python hose three times, this ensures that the beer passing through the python hose is not heated. Structurally, this is achieved in this way. Three lines for propylene glycol of 40 m each are inserted into the python hose with a total length of 40 m, and connected in series, so that the total path of propylene glycol in the python hose is 120 m. The second function of the propylene glycol is to cool the water condenser 5, which is included in of the refrigerating machine I SV - 2000 ROG AK.

The purpose of the cooler SV - 2000 ROGAK is to cool beer (deep cooling) to a temperature of -593 in the heat exchange unit C, immediately before its bottling through the bottling column 4.

The cooler SV - 2000 ROGIAK is a "dry block cooler", in the "dry aluminum block" where the beer is cooled to the required temperature. Beer from keg 1 is served at a temperature of 45 °C through python hose 2. Then, after leaving the python hose 2, beer with the same temperature of 4.59C is fed to b" heat exchange unit 3, where it undergoes its final cooling to a temperature of -5C, and after cooling it is already fed to the bottling column 4, for further pouring into glasses. The function of propylene glycol , c consists in the fact that it, passing through the heat exchange unit C, prevents it from freezing while the line is in recovery mode and beer is not poured.

Installing a water condenser allows you to avoid dependence on the temperature of the environment. Cooling of this element occurs due to the water supplied to it or an aqueous solution of propylene glycol, as in the technical solution proposed by us. The temperature at which propylene glycol - s is supplied to the condenser is practically the same, both in summer and winter. Accordingly, the operation of the condenser does not depend on the ambient temperature, but on the temperature of the propylene glycol at the inlet to the condenser. And the temperature at the entrance to the condenser, in turn, is maintained constant by a separate cooler I SV - 200005 ROI AK. The thermal load on the aluminum heat exchange unit remains practically unchanged, since the beer consumption in all operating modes of the line is unchanged. Thus, with the help of the proposed technical solution, a stable refrigerating cycle occurs, which means stable refrigerating performance of the cooler.

Stable cooling of the water condenser depends not only on the temperature of the propylene glycol at the inlet to the condenser, but also on its consumption. If the flow of propylene glycol will be less, then the cooling of the condenser by 20 will be insufficient, and if the flow increases, then the cooling of the condenser will be excessive.

Both extreme modes will negatively affect the operation of the cooler. Therefore, in the proposed technical solution (32), the consumption of propylene glycol primarily depends on the optimal length of the beer pipe or python hose. If its length is longer than the optimal one, then the consumption will decrease, if it is less, then it will increase. In order to ensure a stable flow of propylene glycol through the water condenser, a water control valve (WWV) is installed at the entrance to the water condenser. This valve is designed to automatically maintain a stable flow of propylene glycol through the water condenser. This water control valve has the ability to manually adjust the required flow rate of propylene glycol through the water condenser, which is then automatically maintained. In the proposed technical solution, the design length of the beer pipe or python hose is at least 40 m. This is the average or most common distance that the dispensing tap 60 is removed from the beer keg storage chamber and has been obtained experimentally and technologically. In the case when, during the installation of the line, it is found that the distance of the beer pipeline is more than 40 m, then a change in its length will cause a change in the set flow of propylene glycol, which will be reflected in the performance of the entire line as a whole. For such situations, installation of a water regulating valve is provided. During start-up and adjustment work, after the installation of the line, the technician will need to adjust the water control valve to the parameters specified in the operating manual, and then the flow rate will be maintained automatically.

The temperature of the dry aluminum block supported by the cooler I SV - 2000 ROG AK lies in the range from -59С to -1.59С, which guarantees normal cooling of the product to negative temperatures. As long as the temperature is within these limits, the chiller is in standby mode and its compressor does not start, because the unit temperature is normal. At the same time, the water control valve 6 is completely closed, and the propylene glycol goes to the heat exchanger 9 through the heat exchange unit C for cooling. Then, when the beer is supplied for cooling, the temperature of the aluminum heat exchange unit C rises, and at a mark of -1.59С00, the compressor of the cooler is turned on, and the temperature drops block, at the same time the automatic opening of the water control valve 6 occurs, and propylene glycol begins to flow to the condenser 5 for cooling. And then 70, mixed with the main flow of propylene glycol, flows to the heat exchanger 9 for cooling.

As can be seen from the above description, the technical solution proposed by the author distinguishes it from existing lines in which propylene glycol is used as a coolant. In traditional cooling lines, there are no cooling devices, for a stable product that has kept negative temperatures, with a flow rate as high as 212 l/h. Moreover, in such lines, the operation of coolers intended for cooling 75 propylene glycol is strictly regulated by the length of the beer pipe or python hose. The proposed, according to this technical solution, line for cooling and bottling keg beer, will allow to vary the length of the beer pipe or the length of the python hose, based on the installation conditions at a specific object, and will also allow to adjust the operation of the line as a whole, based on their specific installation conditions conditions The pump for the circulation of propylene glycol, for the proposed technical solution, is selected according to the final length of the beer pipeline or python hose, depending on the distance from the bottling column to the beer keg storage chamber, and not from the regulated or fixed length of the python hose, as is done in traditional cooling lines.

Traditional devices for cooling propylene glycol in the beer cooling line have a standard design: an aqueous solution of propylene glycol is poured into the bath, and its cooling is carried out by the refrigerating machine of the cooler, the evaporator of which is immersed directly in the bath with propylene glycol.

Cooler I SV - 20005 ROG AK (Fig. 3-8), which we design for cooling propylene glycol in the beer cooling line, does not have such a bath. Cooling of propylene glycol takes place in a brazed Z plate heat exchanger, the installation of which distinguishes the design of this cooler from traditional devices. This, first of all, is connected with the refrigerating capacity, which is capable of developing the cooler I SV - 2000 ROG AK designed by us. Gee!

For guaranteed cooling of the product to negative temperatures (from -52C to -1.5935), the cooler I SV - 20005 ROI AK, designed for cooling propylene glycol in the line being applied for, develops a cooling capacity of 2.6 to 3 kW, depending on mode of operation For example, such a thermal power is possessed by a chamber F) for long-term storage of products with a volume of 12...16 m, in a small grocery store, or 10 "high-class" household refrigerators, with a power of 300 W in the cold. Therefore, in order to achieve such a power, in the proposed F technical solution, a brazed plate heat exchanger is installed as an evaporator of a refrigerating machine. Currently, in the opinion of the author, this model of heat exchanger is the most efficient of all existing models of heat exchangers produced by modern industry. The main advantage of these heat exchangers is high thermal technical characteristics with small overall dimensions, high thermal power, and the design of the heat exchanger allows for very efficient heat exchange.

Structurally, the heat exchanger consists of recruitment plates, shown on the figure, made of stainless steel - c and soldered together with a copper joint. Each plate has its own topography of channels through which the movement of heat exchange media is carried out, and their number forms a heat exchange surface. ,” The installation of such heat exchangers is not common on traditional propylene glycol coolers in beer cooling lines, due to their small capacity for similar product flows. Varying the length of the python hose leads to some change in the flow rate of propylene glycol. Thus, the heat load on the evaporator of the SV - 2000 ROIAK refrigerating machine, which is served by a brazed plate heat exchanger, changes. In order to cope with the variable heat load, it is necessary to maintain an appropriate amount of freon entering the brazed plate heat exchanger for cooling (se) propylene glycol. To solve this problem, the cooler SV - 2000 ROGAK is equipped with a thermoregulating valve. This valve is set to optimally fill the evaporator with freon, depending on

F of the thermal load on it. In most coolers, which are made with the help of similar (Te) structural solutions, a capillary tube with a constant cross-section is equipped. Therefore, due to the fact that the internal cross-section of the capillary tube is constant, the evaporator is also filled with a constant amount of freon. In the thermoregulating valve, the section of the through hole changes depending on the thermal load on the evaporator, which ensures optimal filling of the evaporator with freon. The filling of the evaporator with freon is regulated automatically by the thermoregulating valve. If necessary, this valve can be adjusted manually.

In addition, the proposed line for cooling and bottling keg beer does not depend on the regulated distances between the bar counter and the beer keg storage chamber and allows to remove or minimize excess heat 60 flows around the bar counter and has the ability to be adjusted to specific conditions at the facility. after the implementation of which, it works completely in automatic mode.

Both coolers, which are included in the beer cooling line, have the possibility of automatic shutdown in the event of an accident on the propylene glycol line. For this, coolers are equipped with cartridge pressure regulators or low and high side pressure switches. When the supply of propylene glycol to the water 65 condenser of the SV - 2000 ROGAK cooler is stopped (for example, the propylene glycol pump has failed, or the propylene glycol has leaked on the line), then the high-side pressure switch equipped with this cooler is activated. When the supply of propylene glycol to the water condenser is stopped, it stops cooling and as a result, the pressure on the discharge line of the cooling circuit of the cooler increases, the pressure switch detects this and turns off the cooler. The pressure switch is equipped with a manual reset button, so the chiller will not restart until the problem in the propylene glycol circuit is corrected. Only after troubleshooting by manually pressing the reset button will it be possible to start the cooler. In the case of stopping the supply of propylene glycol to the evaporator of the cooler designed for cooling propylene glycol I SV - 20005

ROGAK, the thermal load on the evaporator will decrease dramatically, and the pressure in the evaporator's cooling circuit will begin to drop. This pressure drop will be detected by the low side pressure switch that the chiller is equipped with and will 7/0 Shut down the chiller. Like the high side pressure relay, it is also equipped with a manual reset button, and the cooler can only be started after troubleshooting. Emergency shutdowns of coolers included in the beer cooling line are carried out automatically. The established failure-free operation is at least 5000 hours for each cooler. The average failure time for each cooler is set to be at least 10,000 hours. The full installed service life of each 7/5 cooler is at least 10 years, including restoration work. The average recovery time is no more than 3.5 hours for each cooler (if no new assemblies are required).

As can be seen from the description of the technical device, it is new and can be widely used for the equipment of cafes, bars and restaurants that specialize in bottling Ket beer.
