Next, the operation control system of the cold storage device 100 will be described with reference to FIG. The cold storage device 100 includes a control device 13 for controlling the operation of the entire cold storage device. The control device 13 is composed of a microcomputer, and includes a central processing unit (CPU) (not shown), a read only memory (ROM), and a random access memory (RAM) (random access memory). ) And other internal storage devices. The control device 13 includes an operation unit 36 such as a keyboard and a mouse for connecting to the control device 13 and inputting an operation command, and a display such as a CRT (Cathode Ray Tube) for displaying the driving situation and the like in images and characters.

A refrigerator 7, a first blower 11 and a second blower 12 are connected to the control device 13 and their operation and stop are controlled by the control device 13. In addition, the controller 13 is connected to a first cooler room temperature sensor 38, a second cooler room temperature sensor 39, and a storage cooling room temperature sensor 40, which are temperature detectors. These temperature sensors are attached to the walls of the first cold storage chamber 5, the second cold storage chamber 6, the cold storage chamber 10, etc., and detect the temperature inside each chamber and output them to the controller 13.

Further, the cold storage device 100 has commercial power input terminals 32, 32. The wiring from the commercial power supply input terminals 32, 32 is connected to the refrigerator 7 to supply the refrigerator 7 with commercial power. The wiring from the commercial power source input terminals 32, 32 is connected to a rectifier circuit 33 corresponding to commercial power source detecting means. The rectifier circuit 33 converts the alternating current input from the commercial power source into direct current and inputs the output to the control device 13.

Further, the wiring from the commercial power source input terminals 32, 32 is connected to a battery charger 34 which is a power storage means. The battery charger 34 has a rectifier circuit (not shown) inside, and converts the alternating current input from the commercial power source into direct current and outputs it to the storage battery 35 for charging. The output of the battery charger 34 is input to the storage battery 35 via the changeover switch 41. The changeover switch 41 is connected to the control device 13 and controlled by the control device 13. Further, a voltage sensor 42 is provided on the output line of the storage battery 35, and the voltage of the storage battery 35 is detected and sent to the control device 13.

Next, the operation control operation of the entire cooler apparatus 100 and the accompanying operation in the cooler apparatus 100 will be described with reference to FIGS. 1 to 4. First, when a CPU (not shown) in the control device 13 sends an operation control signal s1 to the refrigerator 7, the refrigerator 7 is operated, and the liquid refrigerant circulating in the cooling pipe 22 is stored in the cooling device 2. It is decompressed in the cooling pipe 22 and vaporized, and at this time, the heat in the animal cooling device 2 is taken, so that heat is exchanged between the animal cooling material and the refrigerant in the animal cooling device 2 to be described later. The temperature drops. As a result, the animal cooling material installed in the animal cooling device 2 is frozen, and the animal cooling material is cooled.

The refrigerant vaporized in the cooling pipe 22 in the stock cooling device 2 is sent to the compressor 18 by a pipe (not shown) and is compressed to be a high temperature and high pressure gas. This high-temperature, high-pressure gaseous refrigerant is sent to the condenser 19, cooled by a heat radiation fan or the like, and liquefied. This liquefied refrigerant is again sent to the animal storage cooling device 2 through a pipe (not shown) and used again for animal storage cooling.

At this time, at the same time, the temperature sensor 40 for the inside of the cooling room detects the temperature inside the cooling room 10 and outputs it to the control device 13 as a temperature data signal s2 for the inside of the cooling room. As a result, the CPU (not shown) of the control device 13 detects that the stock cooling material has become below the freezing temperature based on the contents of the stock cooling room temperature data signal s2 related to the room temperature output from the stock cooling room temperature sensor 40 to the control device 13. If so, it means that all the livestock cooling materials have sufficiently solidified (frozen), so the CPU (not shown) of the control device 13 sends a stop control signal s3 to the refrigerator 7 to stop it. As a result, the stock cooling operation is stopped.

When the stock cooling material in the stock cooling device 2 is sufficiently cooled as described above, the air around the stock cooling container 21 is cooled and the specific gravity increases, so that the lower part of the stock cooling chamber 10 is cooled. Sink to. Here, a CPU (not shown) of the control device 13 sends a first blower operation control signal s4 to the first blower 11 or a second blower operation control signal s5 to the second blower 12 to activate one or both of the blowers. Then, the air in the first duct 8 or the air in the second duct 9 is sucked upward.

In FIG. 4, a line with an arrow indicates a streamline of cooled air (cold air). Due to this suction operation, the cold air cooled by the stock cooling device 2 moves inside the stock cooling chamber 10 to the left in FIG. 4, and concentrates on the lower opening of the heat insulating wall 17 near the left end of the stock cooling chamber 10 in the figure. After that, the air blows out to the outside of the animal storage room 10 by the blower 49. Next, the cool air rises in the ducts 8 and 9, and the first blower 11 blows the cool air from the stock cooling device 2 introduced into the first duct 8 into the first cool chamber 5. In addition, the second blower 12 blows the cool air from the first cold keeping chamber 5 into the second cold keeping chamber 6 through the ventilation hole 50 introduced into the second duct 9.

The cool air blown out from each blower flows through the inside of the first cool chamber 5 and the inside of the second cool chamber 6 to cool each chamber. The cold air that has cooled each cold room passes through each ventilation hole and enters the connected room. That is, the cold air that has cooled the inside of the second cool chamber 6 passes through the second vent holes 15 and enters the inside of the first cool chamber 5, cools the inside of the first cool chamber 5, and then passes through the first vent holes 14. Then, it circulates again to the animal cooling room 10 and returns.

At this time, the cool air returning from the first ventilation hole 14 descends outside the heat insulating goodwill 16 and is introduced into the cold storage device 2 in the vicinity of the middle bottom of each cold storage unit. In the livestock cooling device 2, the cold air cooled by the livestock cooling material is cooled again by flowing between the cooling pipes 22 and in the vicinity of the livestock cooling container 21. By repeating such a cycle and circulating the cool air between the cold storage chambers, the products and the like in the cold storage chambers 5 and 6 are kept cold.

The above-mentioned cold air circulation is performed by operating the blowers 11 and 12. At this time, at the same time, the first cold room temperature sensor 38 and the second cold room temperature sensor 39 detect the internal temperatures of the first cold room 5 and the second cold room 6 and the CPU (not shown) of the controller 13 And outputs the first cold room temperature data signal s6 and the first cold room temperature data signal s7.

The indoor temperature band of each cold room is preset, and the set room temperature is input to the control device 13 from the outside by the operation unit 36 or stored in a ROM (not shown) or the like in the control device 13. Remembered This set room temperature can be set to an arbitrary temperature by operating the operation unit 36.

When the data signals s6 and s7 related to the room temperature output from any of the above temperature sensors to the control device 13 fall below the lower limit value of the predetermined set room temperature band of the corresponding room. First, the CPU (not shown) of the control device 13 sends the first blower stop control signal s8 or the second blower stop control signal s9 to the corresponding blower to stop it. As a result, the cold air circulation is stopped.

On the contrary, when the data signals s6 and s7 relating to the room temperature output from any of the above temperature sensors to the control device 13 exceed the upper limit value of the predetermined set room temperature band, The CPU (not shown) 13 sends the first blower operation control signal s4 or the second blower operation control signal s5 to the corresponding blower to operate it. As a result, the cold air circulation is started and the corresponding chambers are individually cooled.

By performing the control as described above, it is possible to control so as to maintain different indoor temperatures for each cold room, and, for example, the first cold room 5 may be controlled in an ice temperature zone (for example, − It is possible to control such that the second cold storage chamber 6 is kept cold in a temperature range of 3 ° C. to 0 ° C. and the second cold storage chamber 6 is kept in a refrigerating temperature band (for example, a temperature range of 0 ° C. to 5 ° C.). Therefore, one cold storage device 100 can realize a plurality of low temperature environments for each cold storage room and can control their temperature bands to arbitrary temperatures. Here, the control device 13 corresponds to a temperature control means.

Further, the rectifier circuit 33 detects whether or not the commercial power source can be input from the commercial power source input terminals 32, 32, and outputs the commercial power source detection signal s 10 to the control device 13. ing. The state in which the commercial power source can be input is, for example, a state in which the cold storage device 100 is on standby at a delivery base when mounted on a truck or the like. Further, the state in which the commercial power supply cannot be input is, for example, a state in which the truck or the like is running when the cold storage device 100 is mounted in the truck or the like.

When the CPU (not shown) of the control device 13 detects that commercial power can be input from the commercial power input terminals 32, 32 by the output s10 from the rectifier circuit 33, the refrigerator 7 The refrigerator operation control signal s1 is sent to the refrigerator, and the refrigerator 7 is operated by the electric power from the commercial power source so as to perform the animal cooling operation on the animal cooling material.

Simultaneously with the above-described cooling operation, the CPU (not shown) of the control device 13 sends a changeover switch control signal s11 to the changeover switch 41 to cause the output of the battery charger 34 to be sent to the storage battery 35 side, and the power of the commercial power source to be supplied. The storage battery 35 is controlled to be charged. The electric power charged in this way is stored in one of the cold storage rooms when the cold storage device 100 is mounted on a truck or the like, and when commercial power cannot be input, such as when the truck or the like is running. When the above temperature exceeds the upper limit of the specified room temperature band and it becomes necessary to operate the corresponding blower, it becomes the power source of the blower.

On the contrary, when the CPU (not shown) of the control device 13 detects that the commercial power cannot be input from the commercial power input terminals 32, 32 by the output s10 from the rectifier circuit 33, The changeover switch control signal s12 is sent to the changeover switch 41 to send the electric power from the storage battery 35 charged by the above operation to the blower 11 or the blower 12, and either blower is operated to perform the cold air circulation operation (cooling operation). ) Is performed. In the above, the control device 13 and the changeover switch 41 constitute an operation control means.

A voltage sensor 42 is provided on the output line of the storage battery 35, and the voltage of the storage battery 35 is detected and sent to the control device 13. Therefore, when the charge amount of the storage battery 35 is insufficient, this voltage sensor 42 is used. The storage voltage deficiency detection signal s13 from is sent to the control device 13. When the CPU (not shown) of the control device 13 receives the storage voltage shortage detection signal s13, it sends the changeover switch control signal s11 to the changeover switch 41 again to send the output of the battery charger 34 to the storage battery 35 side, and the commercial power supply The storage battery 35 is controlled to be charged with electric power.

The present invention is not limited to the above embodiment. The above-mentioned embodiment is an exemplification, and has any constitution that is substantially the same as the technical idea described in the scope of claims for utility model registration of the present invention and has the same operational effect. However, it is included in the technical scope of this proposal.

For example, in the above-described embodiment, regarding the arrangement state of the stock cooling containers 21 in the stock cooling device 2, a plurality of stock cooling units in which two stock cooling containers 21 are vertically stacked are arranged in the horizontal direction. The description has been given of the example in which one storage cooling panel is installed to form the storage cooling device with a plurality of storage cooling panels, but the storage cooling device is not limited to this, and the number of storage cooling containers is one or more in total. Any number will do.

In addition, in the above-described embodiment, the animal cooling material is described by taking as an example the one formed by enclosing a mixture of ammonium chloride and cellulose in a pack of synthetic resin or the like, but is not limited to this. Alternatively, it may be a livestock cooling material composed of other components, for example, a plastic resin pack filled with water that freezes to become ice. The point is that any substance can be used as long as it solidifies at a certain low solidification temperature and can take latent heat from the surroundings to cool when melting, and any substance can be used.

In addition, in the above-mentioned embodiment, the case where one cold storage chamber is provided as the cold storage chamber in the cold preservation device 100 and two cold storage chambers are provided as the cold storage chambers have been described as an example. There is no limitation, and the number of stock storage rooms or cold storage rooms may be one or more.

Also, regarding the temperature, there is an advantage that an arbitrary temperature can be realized by adjusting the degree of cooling air blowing. In the above cooler, the animal cooling device is provided in a lowermost room of the plurality of chambers, and the animal cooling device surrounds the animal cooling material and circulates a refrigerant cooled by the refrigerator. In the case of having a cooling pipe for circulation and configured to cool the animal cooling material by heat exchange with the refrigerant, the temperature of the animal cooling material rises because the cooled air sinks downward.
