The container body 100 may be loaded in a loading space of a freight vehicle, and is a configuration that exists separately from a freight vehicle so that it can be separated from the loading space as needed. That is, the container body 100 is a housing that exists independently of a transportation means (eg, a vehicle, a ship, etc.) for loading cargo.

The container body 100 may be formed in a hexahedral shape by a plurality of wall portions 180A, 180B, 180C, and 180D. Here, the wall portions 180A, 180B, 180C, 180D are made of iron plates 181A, 181B, 181C, 181D, 183A, 183B, 183C, 183D and urethane foams 182A, 182B, 182C, 182D having a constant thickness. By including it, it is possible to block the cold air inside the container body 100 from escaping to the outside. Specifically, iron plates (181A, 181B, 181C, 181D, 183A, 183B, 183C, 183D) are attached to one side and the other side of the urethane foam (182A, 182B, 182C, 182D), respectively, and implemented in the form of a sandwich panel. Can be.

In addition, a plurality of coupling members (140, 150, 160, 170) are respectively positioned at the point where each of the wall parts (180A, 180B, 180C, 180D) contacts, thereby forming a plurality of wall parts (180A, 180B, 180C, 180D). You can connect.

Meanwhile, the inner space of the container body 100 may be divided into a freezing chamber 110 and a machine chamber 120 by a partition wall 130. Here, the partition wall 130 is implemented as a sandwich panel in which iron plates 132 and 134 are attached to one side and the other side of the urethane foam 133, respectively, and a heat reflective insulating material 131 on the iron plate 132 in the direction of the freezing chamber 110 Is attached, and a heat-resistant insulating material 135 may be attached on the steel plate 134 in the direction of the machine room 120. In addition, a heat reflector 136 may be stacked on the heat-resistant insulating material 135.

In one embodiment, the heat reflector 136 may be an aluminum panel. The heat reflector 136 reflects heat from the surface of the heat reflector 136 so that heat generated inside the machine room 120 does not pass through the partition wall 130 and is not transferred to the freezing chamber 110.

The heat-resistant insulating material 135 attached to the lower portion of the heat reflector 136 may be applied as a heat-resistant material capable of withstanding a high temperature of 600°C or higher. That is, the heat-resistant insulating material 135 may block transfer of the heat generated inside the machine room 120 to the steel plate 134 or the urethane foam 133 even though some of the heat generated inside the machine room 120 passes through the heat reflector 136. In one embodiment, the heat-resistant insulating material 135 may be made of silica airgel, and a commercial product may use Pyrogel, but is not limited to the above-described type.

The freezing compartment 110 is a space for storing items that need to be frozen, such as concentrated aquatic products or food, and the interior of the freezing compartment 110 may be opened and closed by the first door 111 of the freezing compartment and the second door 112 of the freezing compartment. In addition, due to the heat-reflecting insulation 114 attached to the inner wall of the freezing chamber 110, the cold air of the freezing chamber 110 is blocked from escaping to the outside of the freezing chamber 110, and the temperature of the freezing chamber 110 is easily maintained. I can.

In addition, a temperature sensor 700 is installed in the freezing chamber 110 to detect the internal temperature of the freezing chamber 110 in real time, and the measured temperature information may be transmitted to the communication unit 800.

The refrigerator 200 is a device for supplying cold air to the freezing chamber 110 and may be installed above the inner wall of the freezing chamber 110. In addition, the refrigerator 200 is connected to the outdoor unit 210 located in the machine room 120 and may supply cold air to the freezing chamber 110 through heat exchange between the air in the freezing chamber 110 and the refrigerant.

The auxiliary cooling means 900 is disposed on the upper side of the freezing chamber 110 by a plurality of frames 113A and 113B installed on the upper side of the freezing chamber 110, and the refrigerator 200 is malfunctioning or non-operating due to an unexpected error. Even when the cold air is released, the temperature of the freezing chamber 110 can be maintained at a constant level. In one embodiment, the auxiliary cooling means 900 may include packs 910, 920, 930, and 940 for maintaining cool air and a solid refrigerant 950.

The packs 910, 920, 930, and 940 for maintaining cool air may be applied as a case in which a phase change material (PCM) is provided therein. Here, as the type of the phase change material, a known organic phase change material (Organic PCM), an inorganic phase change material (Inorganic PCM), a eutectic mixture phase change material (Eutectic PCM), or the like may be used. As a specific example, paraffin may be applied as a phase change material that enters the packs 910, 920, 930, and 940 for maintaining cool air, but other known phase change materials may also be applied.

The packs 910, 920, 930, and 940 for maintaining cold air accumulate cold air through a phase change material during normal operation of the refrigerator 200, and release the refrigerated cold air when the refrigerator 200 malfunctions or does not operate, It is possible to maintain the freshness of the items loaded under the packs 910, 920, 930, and 940 for maintaining cold air.

In one embodiment, the packs 910, 920, 930, and 940 for maintaining cold air may be applied in a rectangular hexahedral shape to facilitate loading and placement. In particular, the cold air retention packs 910, 920, 930, and 940 maintain a state in which a plurality of the cold air retention packs 910, 920, 930, and 940 are exposed to air can be reduced. The temperature of the packs 910, 920, 930, and 940 for maintaining cool air may be maintained at a lower temperature than the packs 910, 920, 930, and 940 for maintaining cool air are disposed individually without contacting each other.

The solid refrigerant 950 may be positioned on one side of the packs 910, 920, 930, and 940 for cooling air to cool the phase change material. In one embodiment, the solid refrigerant 950 may be applied as dry ice, and the phase change material may be rapidly cooled while the solid refrigerant 950 evaporates. In addition, the phase change material cooled by the solid refrigerant 950 may be continuously cooled by the cold air discharged from the refrigerator 200.

In one embodiment, a plurality of cold air retention packs 910, 920, 930, and 940 may be arranged in a line while maintaining contact with each other, and a plurality of cold air retention packs 910, 920, 930, 940 and A solid refrigerant 950 may be disposed in adjacent rows. For example, when the first row is composed of a plurality of packs for maintaining cold air, a solid refrigerant is disposed in a second row adjacent to the first row, and a plurality of packs for maintaining cool air are disposed in the third row. When the solid refrigerant in the second row in the third row is vaporized, the pack for maintaining cold air in the first row and the third row may be cooled at the same time.

In addition, the auxiliary cooling means 900 is disposed in front of the refrigerator 200, so that the cold air discharged from the refrigerator 200 drops the temperature of the phase change material inside the packs 910, 920, 930, 940 It can contribute to cooling the phase change material. During the operation of the refrigerator 200, the phase change material may be maintained in a cooled state due to vaporization of the solid refrigerant 950 and cold air discharged from the refrigerator 200.

Therefore, even when the freezer 200 is not operated due to an error, cold air is discharged by the packs 910, 920, 930, and 940 for maintaining cool air, so that the temperature of the freezer 110 can be kept at a constant low temperature. 110) can be operated stably.

Moreover, since the internal temperature of the freezing chamber 110 can be kept constant due to the phase change material of the auxiliary cooling means 900 and the solid refrigerant 950, it is necessary to forcefully lower the set temperature of the refrigerator 200 to maintain a low temperature. There is no That is, in one embodiment, the auxiliary cooling means 900 prevents overheating of the refrigerator 200 during normal operation of the refrigerator 200 and improves durability of the equipment.

The machine room 120 is a space in which equipment for operating a refrigeration container is installed, and the interior of the machine room 120 may be opened and closed by the machine room first door 121 and the machine room second door 122. Since the heat-resistant insulating material 126 is attached to the lower portion of the steel plate 183A of the upper inner wall of the machine room 120, it is possible to prevent the temperature inside the machine room 120 from rising due to direct sunlight outside the container body 100. When the ceiling of the machine room 120 is overheated by direct sunlight, the operation of the outdoor unit 210 may be limited, but in one embodiment, a heat-resistant insulating material 126 is attached to the lower part of the steel plate 183A of the upper inner wall of the machine room 120 Cooling performance may be prevented from deteriorating due to overheating of the outdoor unit 210 by direct sunlight.

On the other hand, in the case of the heat-resistant insulating material 126 manufactured using silica airgel, fine dust may be generated on the surface of the insulating material as time elapses, and fine dust inhibits the combustion of the generator 300 located inside the machine room 120 and , Since there is a concern that the lifespan of the outdoor unit 210 may be shortened, the finishing material 127 is attached to the lower portion of the heat-resistant insulating material 126 in one embodiment to prevent fine dust from scattering from the heat-resistant insulating material 126.

An outdoor unit ventilation opening 1211 may be installed above the machine room first door 121. The hot air generated from the outdoor unit 210 is discharged to the outside of the machine room 120 through the outdoor unit ventilation opening 1211. A generator vent 1212 and a fan vent 1213 may be installed under the machine room first door 121. The generator vent 1212 helps to discharge heat generated from the generator 300 to the outside of the machine room 120.

The heat dissipation unit 123 may quickly discharge heat and exhaust gas generated from the generator 300 to the outside of the machine room 120, and the heat dissipation unit 123 may be coupled to the fan vent 1213. That is, the heat and exhaust gas sucked by the heat dissipation unit 123 are discharged to the outside of the machine room 120 through the fan ventilation opening 1213.

A plurality of intake ports 1221 and 1222 are formed in the second door 122 of the machine room, and external air supply units 124 and 125 may be coupled to each of the intake ports 1221 and 1222, respectively. The outside air supply units 124 and 125 may suck outside air required for combustion of the generator 300 from the outside of the machine room 120 and supply the inside of the machine room 120. In one embodiment, the interior space of the machine room 120 may be divided up and down by the upper and lower partitions 128, and a plurality of external air supply units 124 and 125 are disposed on the upper and lower sides based on the upper and lower partitions 128. Can be.

That is, the outdoor air supply unit 124 disposed above the upper and lower partitions 128 serves to ventilate the interior of the machine room 120 by continuously supplying outdoor air so as not to overheat when the outdoor unit 210 is operated, and the upper and lower partitions The outside air supply unit 125 disposed below the 128 supplies fresh air from the outside to the inside of the machine room 120 to facilitate combustion of the generator 300.

Iron plates 1281 and 1283 are attached to one side and the other side of the urethane foam 1282 constituting the upper and lower partitions 128, respectively, and a heat-resistant insulating material (in the lower portion of the iron plate 1283 located at the lower side of the upper and lower partitions 128) ( 1284 is attached, and a heat reflector 1285 may be attached to a lower portion of the heat-resistant insulating material 1284. Here, the heat reflector 1285 collects heat generated from the generator 300 on the surface of the heat reflector 1285 so that the heat generated by the generator 300 is not transferred to the upper direction of the machine room 120 when the generator 300 is operated. Reflect. That is, the heat generated from the generator 300 is primarily blocked by the heat reflector 1285, and the heat that has partially passed through the heat reflector 1285 is secondarily blocked by the heat-resistant insulating material 1284, so the generator 300 Heat due to can be prevented from being transferred to the upper side.

The outdoor unit 210 is an equipment for condensing or evaporating a refrigerant by compressing a refrigerant and exchanging heat with outdoor air and refrigerant. The outdoor unit spacer 211 supports the outdoor unit 210 from the lower side of the outdoor unit 210 so that the outdoor unit 210 is located at a predetermined interval from the upper and lower partition units 128. In addition, the lower side of the outdoor unit spacer 211 may be fixed to the upper surface of the upper and lower partitions 128. In one embodiment, the heat generated from the generator 300 is secondarily blocked by the heat-resistant insulating material 1284 and the heat reflector 1285 of the upper and lower compartments 128, and furthermore, by the outdoor unit spacer 211. Since the outdoor unit 210 maintains a state spaced apart from the upper and lower partitions 128, overheating of the outdoor unit 210 due to heat transfer from the generator 300 is more reliably prevented.

The generator 300 may include a fuel tank (not shown) having a predetermined capacity inside the generator 300. In one embodiment, the generator 300 is located on the lower side of the machine room 120, and more specifically, the generator is located on the lower side of the upper and lower partitions 128 based on the upper and lower partitions 128 of the machine room 120. I can.

In addition, the generator 300 may generate power while being driven by receiving fuel from a fuel tank therein. In addition, one side of the generator 300 may be connected to the auxiliary fuel tank 330 to generate power while being driven by fuel additionally supplied from the auxiliary fuel tank 330. For example, when the generator 300 receives additional fuel supply from the auxiliary fuel tank 330, it can be driven for 36 to 40 hours and generate power. Of course, since the capacity of the auxiliary fuel tank 330 can be changed as much as it is implemented, it is possible to extend the driving time of the generator 300 or adjust the driving time in consideration of the user's situation.

A generator fixing device (not shown) that fixes the location of the generator 300 so that the location of the generator 300 does not shake during the transport of the container body 100 may be further installed on the inner wall of the machine room 120.

The direction maintaining unit 310 is connected to the exhaust gas outlet 311 of the generator 300 and may maintain a constant discharge direction of the exhaust gas discharged when the generator 300 is driven. In addition, the position fixing unit 320 is coupled to the direction maintaining unit 310 so that the direction maintaining unit 310 can perform its original function without shaking even during the transport of the container body 100 to fix the position of the direction maintaining unit 310 Let it. In one embodiment, one side of the position fixing unit 320 is fixed to the floor of the machine room 120 and the other side is coupled with the direction maintaining unit 310 so that the position of the direction maintaining unit 310 may be firmly fixed.

Here, as one end of the direction maintaining part 310 is disposed close to each other with the heat dissipating part 123, the exhaust gas discharged from the generator 300 can quickly escape from the machine room 120. That is, since one end of the direction maintaining unit 310 is disposed at the rear end of the heat dissipating unit 123, the exhaust gas emitted from the end of the direction maintaining unit 310 may be discharged to the outside of the machine room 120 by the radiating unit 123. . In one embodiment, the direction maintaining unit 310 and the heat dissipating unit 123 are disposed between the direction maintaining unit 310 and the radiating unit 123 so that the direction maintaining unit 310 and the radiating unit 123 are disposed close to each other without contacting each other. The distance can be set to about 10 to 20 cm, but the distance between the two can be flexibly adjusted according to the situation.

Exhaust gas contains various combustion by-products and harmful gases, so if it remains in the machine room 120 for a long time, it may impair the life and performance of each equipment inside the machine room 120, so it is important to discharge it as quickly as possible. , In one embodiment, the direction of movement of the exhaust gas generated from the generator 300 is intentionally adjusted through the direction maintaining unit 310, and the exhaust gas is rapidly discharged to the outside of the machine room 120 by placing it adjacent to the radiating unit 123 Can be discharged.

One side of the battery 400 may be connected to the generator 300 to charge the power generated from the generator 300 in real time. The other side of the battery 400 may be connected to the inverter 410, and the inverter 410 may convert DC power charged in the battery 400 to supply an AC voltage to the refrigerator 200. In one embodiment, the battery 400 may be applied as a lithium iron phosphate battery, but other known types of batteries may be used.

When the generator 300 is driven, the controller 500 controls the operation of the refrigerator 200 using power generated from the generator 300, and when the generator 300 is not driven, the battery 400 is charged. The operation of the refrigerator 200 may be controlled using power.

The power terminal part 600 is a power connection terminal connected to an external power source so as to receive power from an external power source. In addition, the power selection unit 510 is connected to the generator 300, the inverter 410, and the power terminal unit 600, and may supply power to the refrigerator 200 by selecting an arbitrary power supply source among the respective components. In an embodiment, the controller 500 may control the power selection unit 510 to appropriately select power required for driving the refrigerator 200.

For example, the controller 500 may operate the generator 300 for 5 hours to drive the refrigerator 200 with the power generated by the generator 300, and the power generated when the generator 300 is operated. It can be controlled to charge part of the battery 400. Thereafter, when the operation time of the generator 300 is ended, the controller 500 may drive the refrigerator 200 for 1 hour by using the power charged in the battery 400. When 1 hour elapses, the controller 500 may operate the generator 300 again to control the driving of the refrigerator 200 and charging of the battery 400. Here, it goes without saying that the operating time of the generator 300 may be changed flexibly depending on the situation.

In addition, according to implementation, when external power is connected to the power terminal unit 600, the control unit 500 detects this, stops driving the generator 300, and drives the refrigerator 200 using only external power. It is also possible to control the battery 400 to be charged.

Meanwhile, the controller 500 may control power supply by selecting one of the generator 300, the battery 400, and external power so that power is supplied to each equipment requiring power in addition to the refrigerator 200.

The communication unit 800 is connected to the temperature sensor 700 and may receive temperature information sensed by the temperature sensor 700 and transmit it to the user terminal 810 in real time.

As described above, the hybrid-type reefer container 10 capable of self-power generation of the present invention has its own generator 300 in the machine room 120 inside the reefer container, separate from the power source of the freight vehicle or the refrigeration vehicle. Therefore, power can be supplied to the refrigerator 200 through the driving of the generator 300.

In addition, when the generator 300 is driven, the battery 400 is charged with power, and the refrigerator 200 is driven only with the power of the battery 400 when the generator 300 is not operated, thereby reducing the overload of the generator 300. It prevents, and the generator 300 can be efficiently operated.

Further, in an embodiment, since it is directly connected to an external power supply through the power terminal unit 600, the refrigerator 200 can be operated by external power, and the battery 400 can be charged by external power.

In addition, as the auxiliary cooling means 900 is disposed above the freezing chamber 110 so that the temperature of the freezing chamber 110 can be maintained at a constant level even when the refrigerator 200 is not operated, the internal temperature of the freezing chamber 110 is stabilized. It can be maintained and has the effect of improving the long-term storage stability of frozen water. Moreover, since the temperature of the freezing chamber 110 can be maintained at a low temperature even if the refrigerator 200 is not operated for a long time, there is an advantage of preventing an overload of the refrigerator 200.

In addition, since heat in the machine room 120 is blocked from being transferred to the freezing room 110 due to the structure of the partition wall 130 installed between the freezer compartment 110 and the machine room 120, the temperature of the freezing compartment 110 is kept constant. , Since heat inside the machine room 120 is rapidly released to the outside by the heat dissipation unit 123, overheating of each equipment such as the generator 300 and the outdoor unit 210 installed in the machine room 120 is prevented.

In addition, when the temperature sensor 700 detects the temperature of the freezing compartment 110 in real time, the communication unit 800 can transmit temperature information to the user terminal 810, so that the user can monitor the temperature of the freezing compartment 110 in real time. have.

In addition, the hybrid type refrigeration container 10 capable of self-generation according to an embodiment includes a generator 300, a battery 400, an inverter 410, a power selection unit 510, and a power terminal unit in the machine room 120. Equipment such as 600 and outdoor unit 210 are arranged, and the internal space of the machine room 120 is isolated from the outside through the machine room first door 121 and the machine room second door 122 to prevent rain, wind, snow, etc. Since each equipment can be protected from weather conditions, it is possible to stably operate the refrigeration container regardless of weather conditions, and quickly discharge heat and exhaust gas generated inside the machine room 120 to the outside of the machine room 120, Rapid ventilation prevents equipment overheating.

If the internal temperature of the machine room 120 rises excessively, the outdoor unit 210 may be overheated and the operation of the outdoor unit 210 may be stopped, but in one embodiment, the heat-resistant insulating material 1284 of the upper and lower compartments 128 ) And the heat reflector 1285 prevents the heat generated from the generator 300 from being transferred to the outdoor unit 210, and the outdoor unit 210 is separated from the upper and lower partitions 128 by the outdoor unit separation unit 211 Therefore, it is possible to more reliably prevent the outdoor unit 210 from overheating due to heat transfer of the generator 300.

Furthermore, since the air inside the machine room 120 is rapidly circulated by the heat dissipation unit 123 and the outside air supply units 124 and 125, the generator 300 can be smoothly burned, and the outdoor unit 210 can be easily operated without overheating. It can, and this contributes to the improvement of the life and durability of each equipment installed inside the machine room (120).
