Definitions
- the present invention relates to the field of transport and distribution of thermosensitive products, such as pharmaceuticals and foodstuffs.
- Controlled and controlled temperature transport has become a major challenge in the context of the respect of the cold chain, which is essential for maintaining the quality and viability of organic products, whether they be foodstuffs or medicines, vaccines, bio -Samples, etc.
- perishable food products are transported fresh or frozen (positive or negative temperature), while drugs and vaccines are transported fresh (positive temperature).
- the transport typically takes place between the place of production, the places of storage or distribution, and the places of sale and / or consumption.
- Fresh or frozen food is transported by refrigerated truck. This transport relies mainly on "mechanical" groups of cold generation. It is also possible to use so-called “cryogenic” solutions based on the use of liquid nitrogen or CO 2 as cold sources for maintaining positive (fresh) or negative (frozen) cold.
- cryogenic solutions whether it is so-called “direct” injections into the interior of the storage room or products (spray) or so-called “indirect” injections (where the cryogenic fluid is then conveyed from a cryogenic tank on board the refrigerated truck (usually below the truck) to one or more heat exchangers located inside the cold room or chambers of the truck) are well indexed, but see their market penetration curbed by the associated economic cost.
- cryogen nitrogen or CO 2
- the present invention seeks to provide a solution for recovering at least part of the cold given to the walls for later reuse during the operational phase of the truck.
- the present invention proposes a new structure of walls, which can be summarized as follows:
- the following succession of layers starting from the inside of the box a conductive layer, a layer of phase-change material, a layer of polyurethane, and a plastic layer, the conductive layer on the inside of the body acting as a thermal transmission plate to the phase change material;
- the phase-change material is chosen so as to obtain a suitable melting point according to the type of application targeted (transport in fresh, frozen) and the desired temperature range (very specific temperature ranges, for example for certain products biological).
- a phase-change material whose melting temperature is only a few degrees higher than the target temperature referred to in the chamber in question is preferentially used according to the invention. 2 to 10 ° C above the set temperature and more preferably from 3 to 5 ° C.
- a material with a melting temperature of + 8 ° C. for fresh transport and with a melting point of -10 ° C. for frozen food is chosen according to the invention.
- These materials can be chosen in the range of organic materials including waxes, oils, fatty acids and polyglycols or in the range of capsules filled with salt hydrates.
- the advantageous nature of the presence of such a material in the wall of the body is related to its ability to store cold at the time of setting in cold of the truck (at the start, or after a door opening ...), then to restore it when the temperature of the body is higher than the melting temperature.
- the latent heat of melting / solidification then makes it possible to save a large amount of primary energy (nitrogen or CO2 in the case of cryogenic solutions) and thus reduce their consumption.
- the present invention thus relates to a refrigerated product transport vehicle, comprising at least one product storage chamber, of the type in which the cold production system implemented by the vehicle is cryogenic, by direct or indirect injection of a fluid. cryogenic in said at least one storage chamber, and characterized in that:
- phase change The structure of all or part of the walls of at least one of the storage chambers of the truck, one or more panels made of a material called "phase change" type;
- the phase-change material has a melting temperature which is only a few degrees higher than the target temperature referred to in the chamber in question, preferably from 2 to 10 ° C. higher than said setpoint, and still more preferably from 3 to 5 ° C higher than the said set point.
- the phase-change material is incorporated in all or part of the wall half located on the side of the cold source (storage chamber side), and even more preferably in all or part of the wall third located on the side of the cold source.
- FIG. 1 then illustrates in section, not its two views a) and b): in a): a wall structure that is encountered in certain current trucks, with the succession, starting from the inside of the checkout, a conductive layer 1, a polyurethane layer 2, and a plastic layer 3;
- a layer 4 of phase change material is incorporated substantially in the half wall which is the side of the room.
- the start of the cold production system makes it possible to lower the temperature of the air internal to the chamber to the setpoint, then maintain this temperature by system regulation.
- the existing solutions for controlling the temperature of the air internal to the body storing the products transported use control algorithms of the opening / closing of the valves supplying the injectors or internal exchangers at the cryogenic box.
- the time required to reach the set point at first start and after each door opening depends on several parameters, mainly the maximum cooling capacity that can be provided by the cold production system, but also the indoor / outdoor temperature difference. and thermo-physical properties (including conductivity) of the materials composing the walls of the truck.
- cryogen to lower the internal temperature to the storage room products at a required setpoint (for example since 20-25 ° C up to + 4 ° C for fresh products), whether direct injection (spray) or indirect injection (exchangers).
- a required setpoint for example since 20-25 ° C up to + 4 ° C for fresh products
- direct injection sinum
- exchangers indirect injection
- the energy storage in the material will then start before the internal air temperature setpoint has been reached, and the partial or complete solidification of the material before the set the air internal to the chamber has been reached will depend on different parameters, mainly its thermo-physical properties (conductivity, heat mass), and the amount of material used (the mass), but one preferentially attaches to selecting the right amount of suitable material for the material to be completely or almost completely solidified when the temperature reaches the internal set point at the body.
- the material will give off a little energy (sensible heat variation), helping the air to return to its temperature , it can then be used as buffer to better smooth the temperature variation.
- the temperature control system present on such vehicles, by the control of the opening / closing of the valves supplying injectors or internal exchangers to the cryogenic body according to an internal temperature take into account (benefit) of course the energy input from the phase change material panels.
- phase change material with a melting temperature slightly higher than the desired air temperature is very advantageous since, on the other hand, a material with a melting temperature below the set temperature would continue to store. energy during the maintenance phase (a useless process), and that, moreover, with each return at the set temperature, it would continue to consume energy since naturally it will tend to want to solidify.
