Logistics is increasingly important in modern society. In modern society, mass production and mass consumption of goods are usually carried out, and the production and consumption areas are often different. In addition, logistics will function to collect and distribute goods.

With the development of mail-order sales and courier delivery, the importance of markets, shopping malls, and stores in the sense of place decreases, but the importance of logistics connecting producers and consumers is growing.

In the case of ordinary industrial products, if there is no special physical damage in the course of distribution, the value of the product does not deteriorate significantly at the distribution price. may be seriously damaged. For example, fresh foods such as vegetables, fruits, fish, and meat lose their freshness when the shelf life is prolonged, and the product value decreases due to spoilage and deterioration. Some medicines, such as vaccines, can also affect the health and life of the person being vaccinated if certain temperature conditions are not met.

In large production facilities and large distribution facilities, it is relatively easy to maintain these temperature conditions due to capital and facility administration, but in the case of transport vehicles, it may be difficult to carry out transportation and delivery while precisely adjusting to the storage temperature of specific items. The travel time by vehicle may vary depending on the distance between regions depending on traffic conditions, but it is very important to manage the temperature stably and efficiently for a considerable period of time.

In the past, refrigerating or refrigerated vehicles are operated by combining refrigeration facilities or refrigeration facilities with the container space to properly maintain and manage the temperature of cargo. They often fall, and maintaining a large space within an accurate, constant temperature range is not easy and is often problematic.

Korean Patent Publication No. 10-2013-0096398 discloses a storage box for logistics and transportation of a composite material made by filling multiple compartments of a phase change material. The storage box maintains a constant temperature by using the heat storage of the phase change material, and the concept of increasing the efficiency of maintaining the constant temperature by blocking the heat exchange with the outside by combining an insulating material is disclosed.

In addition, a system for managing transported goods by using a sensor coupled to such a storage box for logistics transport, a communication means, a terminal, a server, and the like is disclosed.

However, the temperature conditions maintained for such a storage box are determined depending on which phase change material is used. This has extremely limited limitations.

In addition, the time for temperature management by the combination of the phase change material and the insulating material is usually limited, and thus there is a problem that the suitability of the storage box may be deteriorated due to long-distance transportation or transportation in rush hour.

Hereinafter, the present invention will be described in more detail through specific examples with reference to the drawings.

1 is a perspective view schematically showing a vehicle 1 as a vehicle having a cargo container 100 according to an embodiment of the present invention, and FIG. It is a schematic cross-sectional view showing a cross section cut by a plane.

Referring to Figure 1, the constant temperature logistics container 100 has an approximately rectangular box shape, and referring to Figure 2, on the inner side of each of the left and right walls and the upper and lower walls constituting the constant temperature logistics container body 110, the inner space of the container is heated to a constant temperature. The panel-type module 200 is installed as a configuration that can be managed. Such a module may of course be installed on the front and rear surfaces of the container box, thereby enclosing the inner space of the container box without gaps.

Although such a panel-type module 200 may not necessarily be installed on all the inner surfaces of the walls of the container body 110, at least the heat insulation layer is installed to cover all the inner surfaces of the walls without gaps, so that the inner space of the container can properly enjoy the insulation effect. It is preferable to do so.

(Example 1)

3 is a panel-type module 200 installed inside one wall of the constant temperature logistics container body according to the first embodiment of the present invention, the phase change material layer 230, the heat transfer means 220, which are components constituting the module 200; It is a conceptual exploded perspective view showing a simplified state in which the insulating layer 210 and the reinforcing layer 240 are separated and spaced apart from each other.

A component that directly touches the inner surface of the cargo container wall and covers the container as a whole is the heat insulation layer 210, the heat transfer means 220 is located inside the heat insulation layer 210, and the phase change material is filled inside the phase change material again. Layer 230 is located. Again, a reinforcing layer 240 is installed inside the phase change material layer 230 to protect the phase change material layer by preventing the cargo and the phase change material layer from coming into direct contact when loading the cargo in the container.

As already mentioned above, these constituent layers are shown as being spaced apart from each other, but in reality, these phase change material layers 230 , heat transfer means 220 , and heat insulation layer 210 are attached and combined in an overlapping state to form an integrated panel module. Thus, when manufacturing the constant temperature distribution container, it is possible to quickly and easily form the constant temperature distribution container of the present invention by installing these modules on the wall of the container body, respectively.

Here, the phase change material layer includes a phase change material, a container-type panel capable of accommodating the phase change material therein, and an inlet 232 and an outlet ( 234). In some embodiments, the inlet may also be formed to serve as the outlet.

For example, a hole is formed at the bottom of the container-type panel, a phase change material is injected through this hole when a phase change material is filled in the container-type panel, and a phase change material is passed through this hole when the phase change material is discharged. can be pulled out

In this case, when the phase change material is injected, the injection device is fixed in close contact with this hole serving as the inlet, preventing the phase change material from leaking out of the hole, and filling the container-type panel with the phase change material from the bottom to the top through the injection pressure, When discharging the phase change material, the suction device is coupled to this hole, this time serving as an outlet, and a separate negative pressure is applied to discharge the phase change material to the outside, or the phase change material is naturally discharged by gravity without a separate negative pressure. can let it flow out.

On the other hand, this container-type panel is equipped with a phase change material sensor 236 that can measure the state of the phase change material and convert the measurement result into an electrical signal such as current or voltage and transmit it to the outside, so that the temperature and liquid phase of the phase change material are installed. Alternatively, the presence or absence of a solid phase can be measured. This phase change material sensor also serves as a communication device for external transmission of electrical signals.

The heat transfer means 220 is made by providing a pipe or a container through which a heat transfer medium can be input and discharged, wherein the heat transfer means 220 is provided with a container-type panel for a heating medium, such as a container-type panel forming a phase change material layer, is done The container-type panel for the heating medium is also provided with an inlet 222 for inputting the heat transfer medium and an outlet 224 for discharging, and only one inlet may be formed to serve as an outlet according to an embodiment.

In this container-type panel for heating medium, a sensor for heating medium is installed that measures the state of the heat transfer medium (material), mainly temperature, and converts the measurement result into an electrical signal such as current or voltage and transmits it to the outside. It also serves as a communication device for external transmission of In addition, in the vicinity of the inlet 222 and the outlet 224, a meter (not shown) for measuring the mass or volume of the heat transfer medium that is input and discharged into the container-type panel for the heating medium may be provided. If the measured values of the sensor and meter are known and the heat capacity or specific heat of the heat transfer medium is known, it is possible to calculate the total amount of heat transfer by the heat transfer medium supplied from the outside to the container-type panel for the heat medium. Of course, the meter may be installed in an external heating medium supply device instead of this panel.

The heat transfer medium serves to transfer heat or cold air to the phase change material for the phase change of the phase change material (here, cold means heat in a negative state, not giving heat, but taking heat away. It can be supplied and discharged in a fluid state such as gas or liquid.

On the other hand, here, a heat transfer medium and a container-type panel for a heat medium accommodating the same as well as a separate heater device 238 are installed as heat transfer means. The heater device 238 is installed on the outer surface of the container-type panel for the phase change material in the form of a thin hot wire or a resistive film. The heater device 238 may rapidly transfer heat to change the phase change material from a solid or gel state to a liquid or sol state.

The heat insulating layer 210 may be made of a variety of known heat insulating materials, and may be used in combination with a vacuum board, airgel vacuum board, airgel blanket, synthetic resin foam, and the like. The foam foam can be used directly in the form of a plate having a certain thickness, and the airgel blanket can be used in a separate package or as a panel placed in a container.

The reinforcing layer 240 or the protective layer is installed on the inner surface of the phase change material layer, and when the cargo is loaded in the container, the phase change material layer and the cargo directly contact, damage the phase change material layer, and the phase change material layer leaks. It can be used to prevent damage, to smooth the surface of the cargo space suitable for cargo transport, or to provide other desired surface conditions.

To this end, the reinforcing layer 240 can be made of a stainless steel plate that is not easily deformed or damaged by an external force due to its mechanical rigidity, and can be formed in the form of a simple flat plate, a perforated plate, or a wire mesh.

In a container having such a configuration, a phase change material layer is prepared by selecting a phase change material that undergoes a phase change in the vicinity of that temperature and supplying it to a panel-type container through an inlet to manage the internal space at a constant temperature specialized for cargo. Of course, the phase change material preferably has a large amount of heat storage required for phase change. When it is necessary to keep it at a lower temperature than the surrounding, the phase change material starts to be frozen in a solid state, and when it needs to be maintained at a high temperature, it is melted in a sol state and used.

A heat transfer medium is used to freeze or melt the phase change material. In order to reduce the amount of heat transfer medium, it is preferable to use a material with a high specific heat. When freezing the phase change material, a heat transfer medium with a lower temperature than the phase change temperature is supplied to the container-type panel for the heating medium, and when melting, the phase change temperature A higher temperature heat transfer medium is used by supplying the container-type panel for the heat medium.

When the heat transfer medium is supplied, in a state in which heat exchange to the outside of the container is suppressed by the heat insulating layer 210 , the heat transfer medium causes a phase change while the phase change material stores heat. At this time, the heat transfer medium itself loses heat or receives heat accordingly to change the temperature.

Then, by using the amount of heat storage (latent heat) until the phase change state of the phase change material is restored to the original state, heat is taken or supplied from the cargo loaded in the container interior space, and when the temperature reaches a certain temperature, the state is restored. keep it for quite some time.

Although the supply temperature of the heat transfer medium may have a significant difference from the storage temperature of the loaded cargo, one side of the heat transfer means 220 is in contact with the heat insulating layer 210 , and one side is in contact with the phase change material layer 230 and the loaded cargo Since it does not directly transfer heat to the phase change material and is mainly used for phase change of the phase change material, damage and deterioration of the cargo due to the high or low temperature of the heat transfer medium can be prevented, and the cargo is mainly used only at the temperature of the phase change material layer 230 . will be affected

In this configuration, when the type of cargo to be transported is changed, the previously used phase change material is removed from the container-type panel forming the phase change material layer 230 through the outlet 234 , and a phase change material suitable for a new cargo is introduced into the inlet. You can use it by injecting it through (232). Of course, in this case, a heat transfer medium suitable for the new phase change material is used to perform phase change and heat storage of the phase change material.

At this time, if the phase change material is in a solid state, it is made into a liquid state through a heat transfer medium, or heat is rapidly supplied through a separate heater device 238 so that the phase change material is in a liquid state, and then the outlet 234 is closed. so that it can be removed through

In addition, as the transportation period is prolonged, the phase change material for refrigeration of cargo is converted back to a liquid state while taking heat from the cargo or surrounding space from a solid state, and the temperature gradually increases in the liquid state. The low-temperature heat transfer medium is supplied again, or the existing heat-transfer medium whose temperature has risen is removed and the low-temperature heat transfer medium is supplied. Thereby, the low-temperature heat transfer medium lowers the temperature of the phase change material again, makes it solid by phase inversion, and enables the phase change material to maintain the constant temperature logistics container space and the cargo at the phase change temperature.

(Example 2)

Figure 4 is an exploded perspective view disclosing another panel-type module constituting the constant temperature distribution container of the present invention.

Here, compared with the embodiment of FIG. 3 , the phase change material layer 330 and the heat transfer means 320 constituting the panel-type module 300 both have a common feature in that they form a container-type panel, but in the embodiment of FIG. 3 . In this case, the phase change material layer 230 and the heat transfer means 220 are formed as separate container-type panels, and here the two panels are combined with each other to form an integrated state.

In addition, the sensor 336 for the phase change material and the sensor 326 for the heat transfer medium are installed together on one side of the combined container-type panel, and the heater device 338 is also installed in the joint of the two container-type panels.

In this state, heat transfer from the heat transfer medium to the phase change material can be better achieved.

(Example 3)

5 is a perspective perspective view and a tube cross-sectional view showing the phase change material layer 430 and the heat transfer means 420 together in another panel-type module constituting the constant temperature distribution container of the present invention.

This configuration is similar to the phase change material layer and the heat transfer means in the panel module of FIG. 4, but has a difference in the internal configuration.

That is, here, a tube 438 forming a pipe shape in the phase change material layer 430 is provided. The tube 438 has the shape of a pipe evenly distributed over the entire area of the container-shaped panel of the phase-change material layer 430, and thus the tube 438 is evenly distributed in the phase-change material accommodated inside the container-type panel. .

In addition, the tube 438 has a wall 438b and a corrugated space 438c as shown separately on the right side of FIG. 5 to have a cross section that is easily contracted by external pressure. Since the inside of the tube 438 is an empty space, it can accommodate air or other compressible fluid. The wall 438b of the tube is made of a flexible material such as rubber, and can be contracted and deformed by external pressure, and is made of a material with elastic restoring force that returns to its original shape when the external pressure is removed.

When a phase change material undergoes a phase change from liquid to solid, it solidifies from the upper surface as water freezes, or if solidification starts irregularly in the middle layer, the space below it may be closed by the solidified phase change material. have. And, when the volume expansion is made while the phase change material in the closed space is also solidified, the pressure due to the volume expansion strongly acts on the wall of the container-type panel around the phase change material, thereby deforming and damaging the panel wall.

However, when the tube 438 is distributed as shown in FIG. 5 , as the tube is contracted, the expanded volume of the phase change material is partially accommodated in the contracted space, thereby buffering and reducing the pressure. Since the compressive fluid (gas) in the tube 438 can be easily compressed, there is no problem in reducing the pressure due to the phase change of the phase change material, and a part of the tube 438a is exposed outside the phase change material or for the phase change material. When the portion 438a is opened while exposed outside the container-type panel, the compression of the gas in the tube is not a problem, and the increase in internal pressure due to the phase change of the phase change material and the deformation and damage of the panel of the phase change material layer are well prevented. can be prevented

On the other hand, in the container-type panel in which the phase change material is accommodated in this embodiment, a panel support 439 for preventing deformation of the panel by connecting different parts of the wall constituting the panel, for example, the opposite wall, is installed, and this panel support A plurality of holes 439a are installed in the 439 to be evenly distributed so that the phase change material can move through the holes 439a.

In this panel support 439, some spaces are closed as irregular solidification occurs during the phase change process of the phase change material, and when the phase change material is solidified in the space, the space is formed through the hole 439a formed in the panel support. It prevents the formation of a closed space by connecting it, and when bubbles or volume expansion occurs in the closed space, it is easy to form a fine gap between the solidified phase change material and the panel support, so that the material moves through the gap, resulting in increased internal pressure. It can also serve to block the container-type panel, and it can also play a role in preventing tilting, impact, and instability such as sloshing that occurs when the phase change material is in a liquid state and the container moves in a state coupled to the vehicle. have.

(Example 4)

6 is a perspective view showing the phase change material layer 530 and the heat transfer means 520 together in another panel-type module constituting the constant temperature distribution container of the present invention.

This configuration has a point similar to that of the phase change material layer and the heat transfer means in the panel module of FIG. 4, and the heat transfer means 520 is similar in that the inlet 522 and the outlet 524 of the heat transfer medium are formed, The container-shaped panel of the phase change material layer 530 does not have an inlet and an outlet, and an inner space is partitioned, and each inner space has a difference in that a part of the wall 531 is formed to have variability.

For example, the phase change material layer 530 is made of a container-type panel having a relatively wide plate surface facing each other, the interior is divided in the form of dividing the plate surface, each partition space is filled with a phase change material, the At least one of the plate parts constituting the partition space has a corrugated surface, a concave surface or a convex surface with a larger area than a simple plane, so that when the phase change material expands in volume due to the phase change, the phase change space increases without being damaged. It is adapted to accommodate the expanded volume of the conversion material.

The reinforcing layer has mechanical rigidity and can be made of a stainless steel plate that is not easily deformed or damaged by an external force, and is formed in the form of a simple flat plate, a perforated plate 540 having a hole 542 as shown in FIG. 6 or a wire mesh. It is also possible to

Here, the heat-insulating layer 610 hatched by the dotted line is not installed as a separate part, but forms the heat transfer means 620 and has a configuration integrally coupled with this panel part in the container-type panel for accommodating the heat transfer medium, the panel A pipe 628 for a heat medium through which the heat transfer medium moves is provided. Here, the heat medium pipe 628 is installed to form several bends inside to maintain contact over the entire panel area, and is not a round pipe, but has a very small short side and a very long side in order to increase the contact area with the panel wall. It consists of a square tube with a large rectangular cross-section. An inlet 622 through which the heat transfer medium is injected is formed at the beginning of the pipe, and an outlet 624 through which the heat transfer medium is discharged is formed at the end.

The outlet 624 is connected to the suction pipe of the heat transfer medium supply device, and the inlet 622 is heat-coupled to the injection pipe 651 of the heat transfer medium supply device. The suction pipe is connected to one of the branches ( 663 ) distributed as a plurality of the suction distribution pipe 665 , and the main branch 667 on the output side of the suction distribution pipe 665 is recovered by the refrigerant recovery device. It is connected to the tube 668 . A recovery amount recognition device or recovery amount meter 669 is installed in the recovery pipe 668 of the refrigerant recovery device. The injection pipe 651 is connected to one of the branches 653) distributed in a plurality of the injection distribution pipe 655, and the main branch 657 of the input side of the injection distribution pipe 655 is supplied with a refrigerant. It is connected with the supply pipe 658 of the device. A supply amount recognition device or a supply amount meter 659 is installed in the supply pipe 658 of the refrigerant supply device.

When the panel-type module 600 is installed on each wall constituting the body of the constant temperature distribution container and a plurality of panel-type modules are provided for one constant temperature distribution container, the heat transfer means 620 of each panel-type module 600 is The outlet 624 may be connected to correspond one by one to the plurality of branches 663 of the distribution pipe 665 for suction, and the inlet 622 may be connected to correspond to the plurality of branches 653 of the distribution pipe 655 for injection one by one. can

In the above, a case in which one constant temperature distribution container has a plurality of panel-type modules is exemplified and described, but the outlet of the heat transfer means constituting the panel-type module of the plurality of constant temperature distribution containers having a plurality of distribution pipes for suction or distribution for injection, In combination with the inlet, it may serve to void the heat transfer medium.

8 is a perspective view showing another panel-type module 700 constituting the constant temperature distribution container of the present invention.

Here, one container-type panel 730 is formed so that the container-type panel for accommodating the heat transfer medium and the container-type panel constituting the phase change material layer form one space instead of forming a separate space. That is, an inlet 732 for inputting a phase change material and an outlet 734 for discharging are installed in one container-type panel 730 to allow input and removal of the phase change material, and heat transfer in the panel A pipe 728 through which the medium is transported is also installed, and a pressure buffering tube 738 as shown in FIG. 5 is also installed.

Although the function and shape of the pressure buffer tube 738 are the same as those of the embodiment of FIG. 5 and are not described separately, the pipe 728 through which the heat transfer medium is transported is different from the pipe 628 in the embodiment of FIG. have.

That is, here, the pipe 728 has in common with the embodiment of FIG. 7 in that it is coupled with the inlet 722 at the beginning and the outlet 724 at the end, but is filled in the container-type panel as shown in FIG. It is installed to pass directly through the conversion material 729, and since the heat of the heat transfer medium in the pipe is not transferred to the phase change material through the panel wall, there is no need to have a square tube shape that facilitates contact with the panel wall. , a pipe 728 in which a contact area with the phase change material 729 is increased by further forming a screw-shaped pin 728a on the outer surface of the circular tube as shown in FIG. 9 may be used.

The heat insulating layer 710 shown by hatching on the dotted line is installed in the wall portion in contact with the wall of the container body in the container-type panel as shown in FIG. 7 .

The various sensors 736 installed on the panel, the supply device for supplying and recovering the heat transfer medium, and the recovery device may be configured in the same manner as in the configuration in FIG. 7 or in the previous embodiment.

(Example 7)

10 is a schematic structural diagram conceptually showing that a heat transfer medium moves for action and temperature management in an embodiment of the cargo temperature management logistics system of the present invention.

Here, the panel-type module 700 is installed in a constant temperature distribution container, and the constant temperature distribution container is coupled to a cargo transport means such as a vehicle to be loaded, and is a portion located below the horizontal dotted line. The heat transfer medium pipe 728 constituting the heat transfer means of the panel-type module receives a heat transfer medium whose temperature is set as high or low temperature from the supply device, and, if necessary, heat transfer medium of some low temperature or high temperature state previously filling the pipe. discharged to the recovery device.

Here, the supply device for supplying the heat transfer medium to the panel-type module also serves as a recovery device for the heat transfer medium, is a portion located above the horizontal dotted line, and can be connected to the inlet and outlet of the heat transfer means constituting the panel-type module, respectively. have.

The heat transfer medium supply and recovery device may include a constant temperature heat medium storage 800 as shown in FIG. 10 and a constant temperature heat medium generator 900 such as a cooler that maintains a constant temperature of the heat medium in the heat medium storage.

The heat transfer medium for transferring heat or cold air to the panel-type module is usually stored in the storage 800 at a constant temperature, and when the constant temperature logistics container requiring heat transfer in a state where the latent heat of the phase change material is exhausted is connected to the storage, the storage supplies the heat transfer medium at a constant temperature through the pipe 728, and instead recovers the heat transfer medium that has lost heat or cool air in the pipe.

The heat transfer medium newly filled in the pipe supplies heat or cold air to the adjacent phase change material through heat conduction so that the phase change occurs while accumulating necessary latent heat, and the temperature is changed by losing heat by itself. Since this heat transfer process can be performed even in the process of transporting the constant temperature logistics container by the transport means, there is no need to delay the transport means such as vehicles, ships, and aircraft are continuously connected to the supply device.

On the other hand, the heat transfer medium that has lost the heat recovered from the pipe to the recovery device goes to the constant temperature heat medium generator to obtain new heat, passes through the pipe installed inside, and through heat exchange, the constant temperature heat transfer medium is transferred from the refrigerant with more heat or more cold air. It returns to the stationary heat transfer medium storage and enters the standby state.

For convenience, it is assumed that the constant temperature heating medium storage is maintained at a constant low temperature, but the heating medium temperature may vary within a certain range depending on the surrounding or temporary circumstances. The back can be controlled by means such as sensors and actuators.

The constant temperature heating medium generating station may use a known cooler or a separate low or high temperature heating medium. A cooler usually uses the heat and cold air while making a low-temperature vaporized medium by forcibly expanding and vaporizing the liquid refrigerant mechanically and taking heat away. Without this, high and low temperatures can be achieved.

Such a heat transfer medium supply and recovery device may be installed so that the constant temperature logistics container transport means such as airports, bus terminals, ports, highway rest areas, and gas stations are uniformly distributed regionally, such as at stops, marinas, or stopovers.

A plurality of constant temperature logistics containers are coupled to a number of vehicles and move in a wide variety of areas, and heat is transferred through the exchange of heat transfer media using a number of supply and recovery devices distributed by region, thereby loading into a constant temperature logistics container It becomes possible to maintain and manage the cargo at a constant temperature or a certain temperature range.

This heat transfer medium is a means to quickly transfer a certain amount of heat (cold air) to the constant temperature logistics container, more precisely, to the panel-type module, and the amount of heat is a meter that measures the quality of the input or discharge of the heat transfer medium, and the incoming or outgoing heat transfer medium It can be easily calculated using a sensor that measures the state, especially the temperature. Measurement of this amount of heat can be done similarly to the method of measuring the temperature and amount of hot water while delivering hot water to each customer by the District Heating Corporation, and since it is a general area, the details will be omitted.

Here, the meter and the sensor may be installed in the heat transfer means of the panel-type module as described in the embodiment of FIG. 3 above, or may be installed in the supply/recovery device shown in FIG. 10 .

(Example 8)

11 is a schematic structural diagram conceptually showing that a heat transfer medium moves to act in another embodiment of the cargo temperature management logistics system of the present invention.

Here, unlike the embodiment of FIG. 10 , the heating medium supply and recovery device consists of a constant temperature heating medium generating station without a separate constant temperature heating medium storage, so that the heat transfer means of the constant temperature distribution container is directly connected to the constant temperature heating medium generating station.

Here too, the heating medium generating station may be provided with a third low-temperature heating medium such as various types of coolers or LNG, which are well known in general, and the heat transfer medium that transfers heat to the phase change material while passing through the heat transfer means of the constant temperature logistics container is As it is recovered from the recovery device, it enters the station for generating a constant temperature heating medium, where new heat or cold air is received and transferred back to the constant temperature distribution container.

Of course, in the system of the present invention, it is conceivable that a low temperature heating medium such as a heating medium or LNG used in a cooler of a constant temperature heating medium generating station is directly supplied as a heat transfer means of a constant temperature distribution container, but a cooling medium separate from a cooler or a heating medium of the constant temperature heating medium generating station is considered. It may include the case of supplying it as a heat transfer means of a constant temperature logistics container.

In this case, since there is a separate heating medium storage and it is not possible to operate a large amount of heating medium with a margin while acting as a buffer, the constant temperature heating medium generating station must immediately drive the cooler, etc. For this, it is necessary to have a large cooler capacity.

In addition, the present invention as described above can be related to use waste cooling and heat that is wasted in connection with non-face-to-face socialization, waste increase, carbon zero energy policy, and driving energy problems that occur in electric cold chain systems such as mail-order and courier services. have. For example, heat medium circulation technology by LNG and late-night heat storage system can be combined with this phase change material rapid heat storage technology.

Directly, the present invention can be a technology for improving fuel efficiency and reducing energy of refrigeration tower vehicles, and in the case of electric trucks that are expected to be developed and used in the future, when installing a cooler in the vehicle itself, etc. It is possible to provide a technology that can simultaneously provide power storage and heat storage instead of oiling, and a system that can provide both oil and heat storage at the same time.

In addition, in one aspect, the present invention enables optimal provision and change of a phase change material as well as a heat transfer medium, so that it is possible to deliver an optimized constant temperature and temperature management type cargo delivery according to the characteristics of the cargo, and the panel type of the present invention The module can provide an unfolding technology that widely distributes the existing phase change material storage module and provides a wide and evenly space for loading cargo. The uniformly and widely dispersed refrigerant has the effect of quickly insulating the space.

When the present invention is applied to air logistics, for example, when the heat transfer medium is supplied and replaced at the airport when loading and arriving at the aircraft, the weight of the phase change material, which is usually stored at constant temperature for 3 to 7 days, is measured for the actual operation time (1 hour-24 hours). The mass of the phase change material can be reduced according to time), which has an advantage in reducing air operation costs.

In the above, the present invention has been described through limited embodiments, but these are only illustratively described to help the understanding of the present invention, and the present invention is not limited to these specific embodiments. For example, in the above embodiment, the description is mainly focused on a constant temperature logistics container having a panel-type module, but the combination of the heat insulating layer, the heat transfer means, and the phase change material layer may have other specific forms, and the heat transfer means and the phase change material layer The order of the positions and the presence or absence of the reinforcing layer may be changed according to circumstances.
