Description

Title of the invention: COOLING DEVICE FOR A REFRIGERATION SYSTEM AND ASSOCIATED REFRIGERATION SYSTEM technical field

[0001] The invention relates to the field of cooling refrigeration systems, more particularly refrigeration systems comprising a condenser. The cooling device according to the invention can, in particular, be used to limit the temperature rise of certain components of refrigeration systems. Specifically, the invention relates to a self-contained cooling device configured to cool a refrigeration system according to its environmental conditions.

[0002] The invention further relates to a refrigeration system which includes such a cooling device. Previous technique

[0003] Below, we describe the prior art known from which the invention was developed.

[0004] The widespread use of refrigeration circuits in the industrial and commercial sectors has seen significant growth in recent decades. Indeed, these circuits are found in all sectors, whether in refrigeration systems for storing products at low temperatures, or in air conditioning systems for industrial or residential use, including heat pump systems. All these systems operate on the same principle: extracting heat energy from a low-temperature environment, transporting this same energy, and then releasing it in a high-temperature environment. This is achieved by utilizing the thermodynamic properties of a heat transfer fluid whose evaporation temperature remains very low. The principle is therefore to change the heat transfer fluid through different states so that it can cool the air in a specific location.To evaporate the heat transfer fluid, the ambient air transfers heat to it through a heat exchange. A compressor recovers these vapors, compresses them, and expels them under high pressure. The gas temperature then rises and condenses at a high temperature. The heat released during condensation is expelled outside. At this point, the compressed refrigerant passes through an expansion valve. Its pressure drops, and it evaporates at a much lower temperature, consequently lowering the indoor air temperature.

[0005] One problem associated with different refrigeration systems is the environment in which they are located. Indeed, air conditioning systems are largely located outdoors, and the components for recovering hot outside air, as well as the condenser, are subject to variations in climatic conditions. Generally speaking, refrigeration systems used for preserving food products are often located in dedicated rooms, alongside other equipment that is not necessarily cooled, such as restaurant kitchens, bakeries, or similar establishments.Like refrigeration systems partially mounted outdoors, indoor refrigeration systems tend to generate heat, contributing to an increase in the surrounding temperature. This temperature increase is often due to the use of various other appliances (ovens, cookers, etc.).

[0006] In all cases, the refrigeration system finds itself in an environment in which its operation is altered, in particular an excessive increase in temperature has an impact on that of the heat transfer fluid, which is found in the condensers, and the refrigeration system must therefore consume more energy, more often, to function properly.

[0007] In order to limit energy consumption, solutions aimed at optimizing the use of condensate have emerged. One such solution, described in patent document no. WO2021034185, proposes an air conditioning system that provides the desired cooling inside a building while limiting the amount of heat released into the outside environment by the condensing unit of the air conditioning system during its operation, which would otherwise lead to an increase in air conditioning demand. To achieve this, the condensing unit includes a pipe located inside evaporation pads onto which the water contained in the condensate reservoir is distributed in such a way as to reduce the heat generated in the condensing pipe.

[0008] However, the solutions developed do not allow optimal autonomous cooling of existing systems and are often solutions integrated into the systems, which limits the possibility of adapting these solutions to already existing systems.

[0009] The invention aims to overcome the drawbacks of the prior art. In particular, the invention aims to provide a cooling device that can be integrated into existing refrigeration systems without requiring modifications, and that allows for controlled and autonomous cooling of the refrigeration system.

[0010] The invention further aims to provide a refrigeration system comprising a cooling device. Summary of the invention

Brief description of the drawings

[0021] Other features and advantages of the invention will be better understood from the following description and with reference to the attached drawing, given by way of illustration and not limitation.

[0022] [Fig-1] Fig. 1 represents a diagram of one embodiment of a system refrigeration unit comprising a cooling device according to the invention.

[0023] The figure does not necessarily respect the scales, particularly in thickness, for illustrative purposes.

[0024] Aspects of the present invention are described with reference to functional diagrams of devices (systems) according to embodiments of the invention. Description of embodiments

[0025] Below, we describe a summary of the invention and the associated vocabulary, before presenting the disadvantages of the prior art, and finally showing in more detail how the invention remedies them.

[0026] The terms “fixation”, in the sense of the invention, correspond to the direct or indirect association of one element with respect to another without movement of these elements relative to each other, immovable or removable with one or more intermediate elements.

[0027] The term “removable” in the context of the invention refers to the ability to be easily detached, removed, or disassembled without damaging any fastening means, either because there are no fastening means or because the fastening means are easily and quickly removable (e.g., notch, screw, tab, lug, clips). For example, “removable” should be understood to mean that the object is not fixed by welding or by any other means not designed to allow the object to be detached.

[0028] Thus, as illustrated in [Fig.1], the invention relates to a cooling device 1 for a refrigeration system 2 with a condenser 2-1, the cooling device 1 comprising at least one environmental sensor 10-1, 10-2, 10-3, at least one fluid application means 11, a pump 12 and a control module 13.

[0029] According to the invention, the environmental sensor 10-1, 10-2, 10-3 is configured to measure at least one environmental parameter.

[0030] By way of illustrative examples, the environmental sensor 10-1, 10-2, 10-3 may be a temperature sensor, a humidity sensor, a vibration sensor, or a pressure sensor. It is further envisaged that a cooling device according to the invention may comprise one or more identical environmental sensors or a combination of one or more of the aforementioned environmental sensors.

[0031] Thus, an environmental parameter can correspond to a humidity level, a temperature value, a frequency, etc.

[0032] Still in the invention, the fluid application means 1 includes a fixing means 11-1 adapted to allow the application of the fluid to the condenser 2-1 of the refrigeration system 2. The fluid application means 11 is further fluidically connected to the pump 12.

[0033] The fastening means 11-1 may correspond to a magnetic structure or a fastening allowing a reversible mechanical connection with the condenser and allowing the positioning of the fluid application means 11 directly on the elements of the condenser to be cooled, in particular the piping in which a refrigerant fluid circulates.

[0034] By way of illustrative example, at least one means of applying a fluid 11 may be a spray nozzle.

[0035] A cooling device 1 according to the invention further comprises a pump 12 adapted to be connected to a water supply circuit. The pump 12 may advantageously include a flow meter to control the volume or quantity of water delivered by the fluid application means 11.

[0036] In a particular embodiment, the water supply circuit may include a valve 16, preferably a solenoid valve, fluidly connected to a reservoir 14 and / or to a supply connection 15 to a mains water supply. control module 13 can advantageously control the triggering of pump 12 and consequently the opening of valve 16, more particularly of the channel fluidly connecting the reservoir 14 to pump 12 or the channel fluidly connecting the supply fitting 15 to pump 12.

[0037] The tank 14 can be connected to a condensate drain 2-21 of the refrigeration system 2 and to the pump 12 by the valve 16. In this way, it is possible to recycle the condensate in order to reuse it to cool the condenser when necessary.

[0038] The supply fitting 15 may further include a pressure regulator and may also include a descaling cartridge.

[0039] In the invention, the cooling device 1 comprises a control module 13 including at least one processor 13-1. The processor 13-1 is configured to determine an environmental value from the measurement of the environmental sensor 10-1, 10-2, 10-3. Thus, the control module 13 is configured to trigger the pump 12 for a predetermined duration, so as to spray water from the fluid application means 11 onto the condenser 2-1, depending on the environmental value. By way of illustration, the processor 13-1 can determine a predetermined application duration corresponding to a pump 12 activation duration based on the environmental value.

[0040] In a particular embodiment, the reservoir 14 may include a level sensor 10-4 configured to communicate with the control module 13. The control module 13 may further be configured to control the opening and / or closing of the reservoir 14 or the supply connection 15 according to the level measured by the level sensor 10-4. Indeed, in order to ensure continuous, autonomous, and optimal cooling, when the volume of condensate recovered in the reservoir 14 is insufficient, the control module 13 may control the closure of the fluid communication channel between the reservoir 14 and the pump 12 and control the opening of the fluid communication channel between the supply connection 15 and the pump 12.

[0041] In a particular embodiment of the cooling device 1 according to the invention, at least one environmental sensor 10-1, 10-2, 10-3 may include a temperature sensor 10-3 arranged to measure the ambient air temperature. For this purpose, the temperature sensor 10-3 may be positioned near the condenser 2-1 so as to allow for a temperature reading that is as representative as possible of the environment of the condenser 2-1.

[0042] Thus, the processor 13-1 can calculate an environmental value based on the ambient air temperature measured by the temperature sensor 10-3. In particular The environmental value can correspond to an index from which the control module 13 determines command instructions for the pump 12, including a cooling cycle comprising one or more applications of a predetermined quantity of water over a given time interval. Indeed, depending on the ambient air temperature, it may be more efficient to apply several quantities of water at regular intervals, so that the applied water can evaporate once applied and thus allow for more efficient cooling of the condenser 2-1.

[0043] Alternatively or in addition, when the cooling device 1 is intended for a refrigeration system 2 with a condenser 2-1 comprising a ventilation means 2-2, at least one environmental sensor 10-1, 10-2, 10-3 may further include a temperature sensor 10-2 for measuring the temperature of the air supplied by the ventilation means 2-2. For this purpose, the temperature sensor 10-2 may be positioned near the ventilation means 2-2 so as to allow for the measurement of the temperature of the air expelled by said ventilation means. Indeed, the temperature of the air expelled by the ventilation means 2-2 characterizes the efficiency of the refrigeration system 2, in particular of the heat transfer fluid; characterizing said temperature makes it possible to determine whether the refrigeration system needs to be cooled, regardless of the ambient air temperature, which might indicate the contrary.

[0044] Thus, the processor 13-1 can calculate an environmental value based on the supply air temperature measured by the temperature sensor 10-2. In particular, the environmental value can correspond to an index from which the control module 13 determines command instructions for the pump 12, including a cooling cycle comprising one or more applications of a predetermined quantity of water over a given time interval. Indeed, depending on the supply air temperature, it may be more efficient to apply several quantities of water at regular intervals, so that the applied water can evaporate once applied and thus allow for more efficient cooling of the condenser 2-1.

[0045] In addition to the embodiments described above, when the cooling device 1 includes a temperature sensor 10-2 for measuring the supply air temperature and a temperature sensor 10-3 for measuring the ambient air temperature, the processor 13-1 can be configured to calculate a temperature difference between the measurements of the supply air temperature and the ambient air temperature by the temperature sensors 10-2 and 10-3. When the temperature difference exceeds a predetermined threshold, the control module 13 is further configured to trigger the pump 12 for a predetermined duration.

[0046] Thus, the processor 13-1 can calculate an environmental value based on the temperature difference between the supply air temperature and the ambient air temperature measured by the temperature sensors 10-2, 10-3. In particular, the The environmental value can correspond to an index from which the control module 13 determines command instructions for the pump 12, including a cooling cycle comprising one or more applications of a predetermined quantity of water over a given time interval. Indeed, depending on the temperature difference, it may be more efficient to apply several quantities of water at regular intervals, so that the applied water can evaporate once applied and thus allow for more efficient cooling of the condenser 2-1.

[0047] Alternatively or in addition, when the cooling device 1 is intended for a refrigeration system 2 with a condenser 2-1 comprising a compressor, at least one environmental sensor may include a vibration sensor for detecting vibrations generated by the compressor. For this purpose, the vibration sensor may be positioned near the condenser, for example on the external structure of the refrigeration system, or directly on the refrigerant line, or even directly on the compressor.

[0048] Thus, the processor 13-1 can calculate an environmental value based on vibration detection by the vibration sensor 10-1. In particular, the environmental value can correspond to an index from which the control module 13 determines control instructions for the pump 12, including a cooling cycle comprising one or more applications of a predetermined quantity of water over a given time interval. Indeed, based on vibration detection, it may be more efficient to apply several quantities of water at regular intervals, so that the applied water can evaporate once applied and thus allow for more efficient cooling of the condenser 2-1. Furthermore, the control module 13 can be configured to determine control instructions when the vibration sensor 10-1 detects vibrations for a predetermined duration.

[0049] In addition, the processor 13-1 can be configured to calculate a pump 12 activation time, said activation time being calculated based on the ambient air temperature and a vibration detection time generated by the compressor. Indeed, it can be advantageous to allow the compressor to complete an initial cycle, often of a predetermined duration, before pump 12 is activated. This ensures, on the one hand, that the refrigeration system has started up correctly, and on the other hand, that the compressor has completed a cooling cycle, since it will have emitted vibrations for a given period after starting.Thus, the start of pump 12 can take place at the end of the cycle, once the vibration sensor no longer detects any vibration, this allows the application of water to the condenser to be optimized by ensuring that the latter has completed a cooling cycle and therefore. a need to be cooled. When the refrigeration system includes a means of ventilation, the cessation of vibrations generated by the compressor often implies the cessation of the means of ventilation, thus the application of water on the condenser, once the vibration sensor no longer detects any vibration, makes it possible to improve the wettability of the condenser, by means of applying a fluid 11 by preventing the means of ventilation, in operation, from limiting the application of water over the entire surface of the condenser.

[0050] In addition, the processor 13-1 can be configured to determine a vibration detection time generated by the compressor and calculate a temperature difference between the measurements of the temperature sensors 10-2, 10-3 of the blown air temperature and the ambient air. From the vibration detection time and the temperature difference, the processor 13-1 can further be configured to calculate a pump activation time 12. This makes it possible to optimize the amount of water applied according to the desired temperature difference.

[0051] In one embodiment of a cooling device 1 according to the invention, said device may include a data memory 13-2 comprising a reference. The reference may include operating temperatures associated with reference heat transfer fluids. The processor 13-1 may be configured to calculate a target operating temperature based on the heat transfer fluid of the refrigeration system 2 with condenser 2-1. Thus, when the temperature difference exceeds the target operating temperature, the control module 13 may further be configured to trigger the pump 12 for a predetermined duration. This advantageously allows for the application of a sufficient quantity of water to return to a desired temperature and ensure proper operation of the heat transfer fluid of the refrigeration system 2.

[0052] When the refrigeration system includes a ventilation means 2-2, the cooling device 1 according to the invention may include a control module 13 configured to command the shutdown of the ventilation means 2-2, prior to the activation of the pump 12, for a predetermined duration. This advantageously prevents the dissemination of the water sprayed by means of applying a fluid 11, to any part other than the condenser and thus increases the wettability of the condenser, or more precisely, the amount of water in contact with the condenser.Furthermore, stopping the ventilation means allows a pressure increase in the condenser, more particularly in the high-pressure part of the condenser, which allows improved evaporation of a larger quantity of water applied to the condenser and consequently improved heat exchange and improved cooling of the condenser when the ventilation means is restarted 2-2.

[0053] Generally, the control module 13 can be connected to the various elements of the device according to the invention by means of a wired or wireless communication bus. The control module 13 may further include a communication module 13-3 configured to receive information from the various sensors and to issue commands to certain elements of the refrigeration system, such as the ventilation means 2-2 and / or the cooling device, in particular the fluid application means 11 or the tank 14 or the supply connection 15 and more generally the valve 16.

[0054] According to a second object, the invention relates to a refrigeration system 2 with a condenser 2-1 comprising a cooling device 1 according to the invention.

[0055] As mentioned previously, one of the advantages of a cooling device according to the invention is that it can be installed on most existing refrigeration systems without requiring modification or adaptation of the structure of the refrigeration systems in question. Thus, the refrigeration system 2 can be an air conditioning system, a cold room, a refrigerated cabinet, or more generally any refrigeration machine suitable for air conditioning, refrigeration, or freezing.

[0056] As shown in [Fig. 1], the refrigeration system 2 can be an air conditioning system. The air conditioning system is connected to the condenser by a fluid circuit that allows the passage of outside air to be cooled, via a first pipe 2-11, to the condenser. Once cooled, the air is returned via a pipe 2-12 to a ventilation system 2-3, allowing the cooled air to be distributed into the desired environment.

[0057] In another refrigeration system 2 with a condenser 2-1 (not shown), said refrigeration system may include a refrigeration tank in which the temperature sensor 10-3, arranged to measure the ambient air temperature, is positioned. In particular, the refrigeration tank may correspond to the refrigeration volume of a refrigerated cabinet or the internal volume of a cold room.

[0058] In this embodiment, the internal temperature of the refrigeration tank constitutes the ambient air, and its temperature rise can indicate a loss of condenser efficiency. The control module 13 can, in particular, be configured to trigger the pump 12 for a predetermined duration, so as to spray water from the fluid application means 1 onto the condenser 2-1, when the ambient air temperature of said tank exceeds a predetermined threshold. The temperature determined by the threshold can, for example, correspond to a temperature close to, but lower than, the temperature at which the condenser ventilation means is configured to activate. Thus, as mentioned previously, this allows the water to be applied directly to the condenser without the ventilation means dispersing the sprayed water and thereby limits its application on the condenser and consequently implies condenser cooling which is not optimal.

[0059] According to a third object, the invention relates to a method for cooling a refrigeration system 2 with a condenser 2-1 implemented by a cooling device 1 according to the invention, said method comprising: - a step of determining an environmental value from the measurement of the environmental sensor, - a step to determine the activation time of pump 12, - a step of projecting water from the fluid application means 1 onto the condenser 2-1, depending on the environmental value.

[0060] When the cooling device 1 comprises a ventilation means 2-2, a temperature sensor 10-2 for measuring the temperature of the air blown by the ventilation means 2-2, and a control module 13 configured to control the shutdown of the ventilation means 2-2, prior to the activation of the pump 12, for a predetermined duration, the cooling method according to the invention may further comprise: - a step of determining an environmental value from the measurement of the environmental sensor, - a step to determine the activation time of pump 12, - a step to control the shutdown of the ventilation unit 2-2, - a step of projecting water from the fluid application means 11 onto the condenser 2-1, depending on the environmental value, - a step to control the start-up of the ventilation means 2-2.

[0061] The invention can be the subject of numerous variations and applications other than those described above. In particular, unless otherwise indicated, the various structural and functional features of each of the embodiments described above should not be considered as combined and / or closely and / or inextricably linked to one another, but rather as mere juxtapositions. Furthermore, the structural and / or functional features of the various embodiments described above may be the subject, in whole or in part, of any different juxtaposition or any different combination.
