Conventionally, in what is called a refrigerated vehicle, a container is fixed to a vehicle or the like, and the interior of the container is cooled by driving a compressor using the engine output of the vehicle. Therefore.

It has been impossible to remove the container from a vehicle and use it at a location such as a port facility, or to load it onto a ship and transport it. For this reason, 1. For example, in a perishable food distribution system, the perishable food transported by a truck loaded with refrigerated containers is unloaded from the container at a wholesale market, auctioned, and then returned to the truck. It was loaded and transported. Therefore, it can be used at any location to save the labor of loading and unloading.

In order to provide a container that can maintain an appropriate indoor temperature, technical problems arise that must be solved.

[Means for solving problems]

This invention was proposed in view of the above-mentioned problems as a solution, and consists of installing a cooling tank on the inner wall surface of a container provided with a heat insulating material inside, filling the cooling tank with prine, and , a refrigerator in which the plines of the cooling tank are passed through a refrigerant evaporator for circulation cooling,
Furthermore, the compressor for the refrigerant is connected to an engine installed separately in the tower so that the power of this engine can be transmitted to the compressor, and furthermore, a sensor is provided inside the container, a thermostat is connected to the sensor, and the thermostat is connected to the compressor. A solenoid valve is connected to operate the accelerator, and fuel from the carburetor is adjusted and sent to the engine by the operation of the accelerator, and the engine is further connected to a battery and can be started by an ignition switch. It is an object of the present invention to provide a refrigerated container packaging f characterized by the following.

[Effect]

This invention cools the inside of the container by circulating and cooling a refrigerant by passing through a refrigerant evaporator in a cooling tank attached to an inner wall surface of the container, and the refrigerant is sent to the condenser. A compressor has been installed. This compressor is driven by the power of a separately mounted engine. Then, by starting the separately mounted engine and activating the cooling cycle, the cooling plines disposed in the container are cooled, thereby cooling the inside of the container. Furthermore, the temperature inside the container is almost O'CC due to the operation of sensors and thermostats.
It can be stored nearby, making it most suitable for transporting fresh foods, etc. In this way, the cooling cycle can be driven anywhere by the power of the engine mounted on the separate tower.

〔Example〕

Hereinafter, one embodiment of the present invention will be described in detail with reference to the accompanying drawings. For convenience of explanation, conventionally known configurations will also be explained at the same time.

Figure 1 shows a longitudinal side view of the refrigerated container device. The inside of each wall of the container (1) is covered with a heat insulating material (2), and the front opening is filled with a heat insulating material (2). It is configured to be closed with a door (3).

A cooling tank (4) is installed on the entire surface inside these heat insulating materials (2), and a prine (5) is sealed in the cooling tank (4). Further, a compression refrigerator (6) is installed on the back side of the container (1). This compression refrigerator (6) is filled with Freon gas as a refrigerant, and the compressor (7) uses this refrigerant'? : Send to condenser (8).

In the condenser (8), the high temperature refrigerant gas sent from the compressor (7) is air-cooled and liquefied by a cooling fan (9). still.

Qt) in the figure is a fan motor. This fan motor a@ is driven by either a general commercial power source or power generation by an engine, which will be described later. Furthermore, the refrigerant takes heat from the surroundings by vaporizing within the passage of the evaporator aυ and returns to the compressor (power).

In addition, a pline (5) flows through the circulation pipe (12) connected to the cooling tank (4) in the evaporator (Itl), and a refrigerant pipe (0) passes through this pline (5). The cooling cycle of the compression refrigerator (6) is as follows: compressor (force → condenser (8) → evaporator Cl1l → compressor (7)
), the refrigerant releases heat and liquefies in the tJ8 condenser (8), absorbs heat from the prine (5) in the evaporator (11) and vaporizes, and repeats liquefaction and vaporization within the cooling cycle. be. Therefore, the prine (5) of the cooling tank (4)
passes through the circulation pipe Q3 at the top of the cooling tank (4) and is sent to the evaporator [υ] by the pump (1, 11).
As mentioned above, the pline (5) is cooled by the evaporator QIIF9, and then flows into the cooling tank (4) from the lower part thereof and is circulated therein. In addition, the 2nd and 3rd wards
As shown in the figure.

A motor 09 and an engine (l[] for generating power of the compressor (MrPJJ) are installed. This motor 09
is one external general commercial power supply (AC 100V or 20V
0■), but should not be limited to this. Also, the engine Qbl is.

A small device that can be mounted on this mfffi and operated independently.
Permitted to use. A clutch rlη is provided between the output shaft of the motor rotor and the drive shaft of the compressor (7), and when the clutch is engaged, the compressor (7) is driven by the motor 09. , the engine 11
A clutch rIak is provided between the output shaft of the compressor (11) and the rapid movement shaft of the compressor (power), and when the clutch a barrel is turned on, the compressor (7) is driven by the engine strike.

Furthermore, the clutch ding and the clutch f arrogance! Move M using solenoid valve a9. That is, when the clutch aη is "on", the clutch a& is "off", and when the clutch q mark is "on", the clutch aη is "off".

This is how the refrigerated container equipment was used in one disaster.

- In a place where an intershell power source can be used, the power source is used to rotate the motor Qcj, and when the clutch αη is connected by the solenoid valve r19, the compressor (7) is driven and the compression refrigerator ( 6) is operated. and the evaporator αυ
The prine (5) cooled inside circulates in the cooling tank (4) to cool the container (1). or.

- In locations where intershell power is unavailable, the engine (1
When the clutch 0& is connected by the electromagnetic valve 01, the compressor (7) is driven and the container (1) P3 is cooled in the same manner as described above.

Therefore, in Figure @4, the engine (16
1 is fed fuel from a carburetor <211, and the amount of fuel supplied to this carburetor Qυ is adjusted by actuation of the accelerator. Also, the detection value of the sensor (c) installed inside the container (1) is set to the thermostat <24

Therefore, the cooling inside the container (1) can be increased, or the cooling inside the container (1) can be reduced by stopping the suppression of the accelerator ■ and slowing down the engine ue to one revolution. Always keep the air temperature in the container (1) almost O.
``It is possible to maintain the CC nearby.

In detail, if the air temperature inside the container (11) falls below 0°C, the thermostat C24 turns off the solenoid valve ■ to slow down the rotation of the engine I61, and then the container (11) 1) When the air temperature inside rises and reaches 1°C, the thermostat c!n is activated again by detecting the temperature of the sensor, and the magnetic valve G1 is turned on and the accelerator is pressed. The output of the engine (161) was increased and the air temperature inside the container (1) was lowered.In this way, the air temperature inside the container (1) was adjusted to approximately O''C, and the air temperature inside the container (1) was adjusted to approximately O''C. ) The fresh foods stored in the container are cooled at an appropriate temperature and are not dried, so their quality does not deteriorate and they are suitable for long-term transportation and storage.

In addition, a flywheel (t) is attached to the shaft of the engine (161).
is connected, and starter motor (2) starts the engine uI9I via the ignition switch (to) connected to the battery (to) and the ignition coil kC301.
