[0002] It is known to control the temperature in one or more closed enclosures and to perform time tracking of sensor values ​​in these enclosures.

[0004] The invention therefore aims to provide a solution to all or part of these problems.

[0036] [Fig.7] is a cross-sectional view of a thermal control and diffusion unit of a locker according to the invention.

[0037] The invention relates to a set 10 of temperature-controlled lockers 1, 2, 3, which can be used, for example, as secure lockers for dispensing, in particular, Pharmaceutical products. An example of the implementation of set 10 of compartments 1, 2, 3 is illustrated in [Fig. 1], in the form of a column of 3 stacked compartments 1, 2, 3. Those skilled in the art will understand that set 10 of compartments can include a larger number of compartments, arranged in as many columns as necessary. Those skilled in the art will also understand that set 10 of compartments can include compartments of different sizes.

[0038] The set 10 of compartments 1, 2, 3 includes a thermal management system for volumes regulated in temperature in a differentiated manner, i.e. the setpoint temperature of one regulated volume is different from the setpoint temperature of another regulated volume.

[0039] A regulated volume corresponds to the internal volume 14 of a compartment 1, as illustrated in [Fig.2] or 3, or even to the internal volume of several compartments 2, 3 in thermal communication with each other.

[0040] Thus, depending on the case, each compartment 1 forms an isolated and thermally regulated volume, or several mechanically independent compartments 2, 3 communicate thermally and together form an isolated and thermally regulated volume.

[0041] Each insulated and thermally regulated volume is equipped with one or more thermal control and diffusion units 4, as illustrated in [Fig.2] or 3. The number of units present in a volume depends on the thermal power required to regulate the volume according to the external conditions of that volume, the thermal power of each thermal control and diffusion unit 4, as well as the desired temperature homogeneity inside that hermetically sealed volume.

[0042] All the thermal control and diffusion units 4 are connected in series with a heat transfer fluid circuit allowing heat exchange between each hermetically sealed volume in which the thermal control and diffusion units 4 are integrated and the heat transfer fluid. Thus, the thermal control and diffusion units 4 are each successively traversed by a portion 45, 451, 452 of said heat transfer fluid circuit, as illustrated in [Fig. 3].

[0043] According to an example of an embodiment illustrated in [Fig.3], the internal volume 14 of a compartment 1 is delimited at least in part by an insulating wall 13 having a thickness, and the thermal control and diffusion unit 4 of said compartment 1 is at least in part integrated into the thickness of the insulating wall 13. According to these arrangements the compactness of the compartment 1 and of the set 10 of compartments 1, 2, 3 is optimized.

[0044] On the other hand, according to another embodiment, the lockers are provided with at least one opening 11, 12, as illustrated in [Fig. 1], allowing the deposit of at least one object to be stored inside a locker and / or the removal of said object deposited inside the locker, the at least one opening being fitted with a hermetic closing device. According to a particular embodiment, an opening 11 is placed on one face of the locker, for example intended for depositing the object, and another opening 12 is placed on another face of the locker, intended for example for the removal by the user of the object which has been deposited for him in this locker; in particular, it is advantageous that the other face be opposite to the face of the locker on which the first opening is placed.

[0045] More particularly, as illustrated in [Fig.7] the openings are secured by a security device 110, 120 which is also, at least in part, integrated into the thickness of the insulating wall 13, in order to further optimize the compactness of the locker 1 and the set 10 of lockers 1, 2, 3.

[0046] In addition, optionally, the device securing the opening of one or more lockers 1, 2, 3 of set 10 is connected to a local or remote server, such that locker(s) 1, 2, 3 are identified in the server. The server is configured to allow the opening of at least one locker for a user authenticated by an identifier transmitted by the user to the server from a mobile terminal, for example, a smartphone. The connection between set 10 of lockers 1, 2, 3 and the server is based on a wired or wireless connection, for example, via a wide area network.

[0047] According to these provisions, each locker in the set of lockers is configured to serve as a secure, connected locker for the automated deposit and delivery of products whose preservation requires differentiated temperature regulation, for example pharmaceutical products.

[0048] On this heat transfer fluid circuit there is also, for example, one or more pumps allowing the circulation of the heat transfer fluid throughout the thermal management system.

[0049] This heat transfer fluid circuit may also include one or more devices for extracting heat from the heat transfer fluid. This heat is then pumped and released into the external environment as needed.

[0050] The thermal control and diffusion units 4 comprise a heat or cold production layer 43, 44 and a heat dissipation layer 41, 42, as illustrated in Figure 3. The heat dissipation layer 41, 42 is used to exchange heat with the volume to be thermally managed. The thermal resistance of the heat dissipation layer 41, 42 is denoted "Rth". This thermal resistance varies predictably as a function of the airflow through the heat dissipation layer 41, 42. Optionally, the heat dissipation layer 41, 42 is equipped with a temperature sensor for measuring the temperature of the heat dissipation layer 41, 42. This temperature is denoted "Ti".

[0051] The heat dissipation layer 41, 42 comprises at least one radiating module 41, for example a radiator, and / or at least one ventilation module 42, for example a fan. Any fans are arranged to force an airflow through the radiator and thus generate forced convection. Regulating this airflow allows for the management of the heat exchanged between the air in the volume to be thermally managed and the radiator through the evolution of the thermal resistance "Rth" of the heat dissipation layer 41, 42. Indeed, increasing the airflow decreases the thermal resistance between the radiator and the volume to be thermally managed.

[0052] A temperature sensor, optionally an atmospheric pressure sensor and a humidity sensor, are placed in the volume to be thermally managed. The temperature thus measured is denoted "Ta". Optionally, the atmospheric pressure thus measured is denoted "P" and the humidity level thus measured is denoted "Hr". The thermal control and diffusion unit 4 is configured to collect the values ​​measured by the sensors at regular intervals, for example between 500 and 5000 ms.

[0053] According to a particular embodiment, the values ​​measured and collected by the thermal control and diffusion unit 4 are time-stamped and transmitted to the remote server for the purpose of monitoring and certifying the quality of the individual thermal management of each locker.

[0054] More particularly, the lockers in set 10 of lockers 1, 2, 3 are equipped with a disinfection module placed in the interior volume of the locker; said disinfection module is for example based on the use of UV-C LEDs, or a device for misting a disinfectant product.

[0055] According to these provisions, each locker in the set of lockers is configured to serve as a secure, connected, and certified locker for the automated deposit and dispensing of products whose preservation requires differentiated temperature regulation and / or periodic disinfection of the internal volume of the lockers, for example for the automated deposit and dispensing of pharmaceutical products.

[0056] At equal thermal power exchanged between the radiator and the volume of air to be thermally managed, the quantity of humidity present in the volume to be thermally managed can be more or less reduced by lowering the temperature of the radiator and adjusting accordingly the airflow through the radiator.

[0057] The circulation of the heat transfer fluid in the portion 45, 451, 452 of the heat transfer fluid circuit, which passes through the thermal control and diffusion unit, is free. Optionally, a temperature sensor is placed to measure the temperature of the heat transfer fluid in said portion. The measurement of this temperature is denoted "T<>".

[0058] The heat or cold production layer 43, 44 comprises, for example, heat or cold production modules 43, 44, such as Peltier effect modules. The Peltier effect modules are powered via dedicated electronics that control and measure the polarity, intensity, frequency, and waveform of the current flowing through the Peltier effect module. These are conventional, very common Peltier effect modules. They will be chosen, in particular, to be significantly oversized in terms of their cooling capacity, so that they can be used within operating ranges with very high efficiency in all possible operating modes of the diffusion unit.

[0059] Thus, one thermal control and diffusion unit 4 is configured to collect, according to a predetermined periodicity, the values ​​measured by at least one temperature sensor; the thermal management system further includes a heat transfer fluid circuit, the at least one thermal control and diffusion unit 4 comprising a heat or cold production layer 43, 44 and a heat dissipation layer 41, 42;at least one thermal control and diffusion unit 4 is traversed by a portion 45, 451, 452 of said heat transfer fluid circuit, said portion 45, 451, 452 being in thermal communication CT with the heat or cold production layer 43, 44, the heat or cold production layer being in thermal communication CT with the heat dissipation layer 41, 42, the heat dissipation layer 41, 42 being in contact with a volume of air present inside at least one compartment 1, 2, 3 of the set 10 of compartments;The thermal management system further includes an external heat or cold production unit, the external unit being coupled to the heat transfer fluid circuit to ensure overall regulation of the heat transfer fluid temperature. At least one thermal control and diffusion unit 4 is thus configured to, based on the values ​​measured by at least one temperature sensor, actuate the heat or cold production layer 43, 44 and the heat dissipation layer 41, 42 so as to maintain a setpoint temperature of the volume of air present inside at least one compartment 1, 2, 3 of the set 10 of compartments 1, 2, 3.

[0060] According to an improved embodiment, the thermal management system further comprises at least one humidity sensor located inside at least one compartment 1, 2, 3, optionally at least one pressure sensor located inside at least one compartment 1, 2, 3, optionally at least one temperature sensor of the heat dissipation layer 41, 42 located inside at least one compartment 1, 2, 3; according to this improved embodiment, at least one thermal control and diffusion unit 4 is configured to collect, at predetermined intervals, the values ​​measured by at least one humidity sensor, optionally by at least one pressure sensor, optionally by the minus a temperature sensor of the heat dissipation layer 41, 42; at least one thermal control and diffusion unit 4 is further configured to, based on the values ​​measured by at least one humidity sensor, optionally by at least one pressure sensor, optionally by at least one temperature sensor of the thermal dissipation layer 41, 42, actuate the heat or cold production layer 43, 44 and the thermal dissipation layer 41, 42 so as to maintain a predetermined setpoint humidity of the volume of air present inside at least one compartment 1, 2, 3 of the set 10 of compartments 1, 2, 3.

[0061] Thus, for example, the thermal control and diffusion unit 4 includes control electronics configured to control, through the characteristics of the electrical signals applied to the Peltier effect modules and any fans: - the amount of heat absorbed on the Peltier module's radiator side, denoted "Qc" - the amount of heat dissipated on the heat transfer fluid block side of the module Peltier « Q. » h - optionally, the rate of condensation of humidity in the radiator (in g / H) denoted "Vc"

[0062] These elements are obtained by calculation, if necessary using the following elements via the control electronics: - The temperature of the radiator "Tt" - The temperature of the heat transfer fluid block "To" - The intensity and polarity of the current flowing in the Peltier effect module - The airflow through the radiator - The "Rth" value of the radiator - Temperature "Ta", pressure "-P", humidity level "RH" and volume volume to be thermally managed - The temperature "ToRef" which is the ideal temperature of the heat transfer fluid - The thermal resistance value "R" of the volume to be thermally managed with the external environment.

[0063] According to one embodiment, when a thermal control and diffusion unit 4 receives a setpoint temperature denoted TaRef and optionally a setpoint humidity denoted « » to be reached within a time ^Ref, the electronics The control body will then implement the following strategies: Operating framework T« < T oRef T0Ref T«>TaRef Qc > 0 and adapted to the duration tRef and the setpoint TaRef Q.>o Optionally Vc>0 and is adapted to the duration ^Ref, optionally to HRRef & to HR- optionally in case of too high an HRRej value, Vc = 0 Operating mode A T« <TaRef Qc< 0 et est adaptée à la durée et à la consigne TaRef Qc< 0 et est adaptée à la durée tRef et à la consigne TaRef e„> o Qh<v Optionnellement Vc > 0 and is adapted to the duration tRef, Optionally to HRRef and HR. In case of too high a value HRRef, Vc = 0 Optionally Vc>0 and is adapted to the duration tRef, to j and to Hr. Optionally, in case of too high a value / / RRef, Vc = 0 Operating mode C: This operating mode, which cannot be physically obtained by continuous operation, is obtained by a rapid alternation of operation in mode A and B. A very specific operating time ratio governs this alternation.Operating mode B.

[0064] In the context of automated product delivery using secure lockers, the ability to locate equipment to remove heat from the heat transfer fluid has the advantage of allowing the selection of where and how unwanted heat will be extracted from an installation, without having to manage this issue at the level of each hermetically sealed volume requiring thermal management.

[0065] Two alternative or complementary methods can be used to extract calories from the heat transfer fluid: - A Free-Cooling type mode - A mode with an air / water refrigeration unit, of the heat pump type.

[0066] According to the typical Free-Cooling mode, schematically illustrated in [Fig. 4], a radiator 62 and fan 61 assembly is placed in the external environment. In order for this The system dissipates heat, so the temperature of the heat transfer fluid must be higher than the ambient air temperature. Therefore, activation of this system, through fan rotation, should only be limited to situations where the heat transfer fluid temperature is higher than the ambient air temperature. The heat transfer fluid circulates freely within the radiator.

[0067] According to the mode with an air / water refrigeration unit 53 for the removal of calories from the heat transfer fluid circuit 50, illustrated schematically by [Fig.5], a refrigeration unit 53 with a condenser (here consisting of the radiator 42 and fan 41) is placed in the external environment and an evaporator 51 is placed at the level of the circuit containing the heat transfer fluid 50. The evaporator 51 of the refrigeration circuit 53 and the heat transfer fluid can then exchange calories.

[0068] As soon as the temperature of the heat transfer fluid rises above the setpoint temperature, the refrigeration unit 53 starts up with the compressor 52 and the fan 4L starting up. The refrigeration unit 53 then stops again when the setpoint temperature is reached again.

[0069] When using a variable power refrigeration unit 53, the refrigeration unit 53 maintains the temperature of the heat transfer fluid within a setpoint temperature range by modulating its cooling power.

[0070] In order for the heat transfer fluid to be able to transport heat between the various thermal control and diffusion units 4 and the heat transfer fluid heat removal system(s), a circulation pump is installed on the heat transfer fluid circuit.

[0071] To improve the system's energy efficiency, the pump flow rate can be modulated by modulating the power supplied to it. At any time, the ideal pump flow rate can be calculated using the volumetric heat capacity of the fluid, the homogeneity of the heat transfer fluid temperature at every point in the circuit, and the "Qh" values ​​of each diffusion unit.

[0072] The compact design of each diffusion unit, along with the reduced diameter of the pipes used for the heat transfer fluid (liquid), allows all these components to be integrated into the insulation of the secure lockers, and consequently, significantly reduces the space required for the thermal management components of the lockers. This advantage, in addition to ensuring airtightness of each locker and the reversibility of each diffusion unit, represents a genuine technological advancement in the design of temperature-controlled secure lockers.

[0073] From an energy perspective, this system offers significantly better efficiency than a conventional system with separate heating and cooling systems for the storage compartments. Indeed, this system is capable of utilizing all of the extracted calories. and the energy spent cooling one compartment in order to heat another. Furthermore, thanks to the features enabled by the diffusion units, this system does not require a central heating system or heating in each individual compartment, as is the case with conventional systems.

[0074] Since the ideal setpoint temperature of the heat transfer fluid is predetermined, it allows the use of a refrigeration unit operating over an extremely short range "T0^ej" and therefore a design of a unit optimized for this application. This results in a much better efficiency compared to conventional refrigeration units, reduced electrical consumption, and a reduced need for heat dissipation to the outside environment.

[0075] In summary, this hybrid thermal management system combines refrigeration technology, a heat transfer system, and an electronically controlled thermal regulation unit (refrigeration unit with refrigerant + heat transfer fluid + multiple reversible, self-contained air distribution units). This system enables: - a further reduction in energy consumption for heat removal from the installation compared to conventional systems. - Independent and reversible temperature control via a hermetically sealed volume - a high compactness of the thermal system in relation to the hermetic volumes to be thermoregulated.
