This type of cold storage refrigerator uses refrigerating agents to keep the items stored in the storage room cool when it is transported on a transport vehicle such as a truck until it reaches its destination. In addition, this type of cold storage refrigerator is provided with a cooling device that can be operated by a commercial power source. Before the cold storage refrigerator is mounted on a transport vehicle, the cooling device is operated to store the refrigerant. However, such a cold storage refrigerator keeps cold storage in a state where articles are stored in the storage room or no articles, so that it can be mounted on a vehicle at any time before being mounted on a transport vehicle. However, in the past, if the cold storage was performed in an environment with low outside air, the temperature in the storage room was lower than the required temperature, and there was a danger that the items stored in the storage room or the stored items would freeze and the product price would decrease. Even when there is a large gap between the freezing temperature of the refrigerating agent and the temperature suitable for refrigerating the goods, the temperature in the storage room may be lower than the required temperature when the refrigerating agent is cold.

After the operation switch 5 is turned on while the external power source 31 is connected, it is first determined whether the refrigerant temperature TF becomes higher than the refrigerant freezing upper limit temperature TFH, and if it becomes high, the compressor 19 is operated (steps SI and S2). If the refrigerating agent temperature TF is not higher than the refrigerating agent freezing upper limit temperature TFH, the process is shifted to step S 3 (step S 1). In the initial state, since the refrigerating agent temperature TF is usually very high, in steps S 1 and In step S2, the compressor 19 is operated to start refrigerating of the refrigerant 13. Next, it is determined whether the refrigerant temperature TF is lower than the lower limit of the refrigerant freezing temperature, and if it becomes lower, the compressor 19 is stopped (steps S3, S4). If the refrigerating agent temperature TF is not lower than the refrigerating agent freezing upper limit temperature TFL, the process proceeds to step S5 (step S3). On the other hand, it is determined whether the storage compartment temperature TR has become lower than the storage compartment lower limit temperature TRL, and if it has become lower, it is determined whether the compressor 19 is in an operating state (steps S5, S6). When the compressor 19 is in the operating state, the processing to prevent the increase in power consumption is moved to step S8 to avoid the operation of the electric heater 15 (step S6). On the other hand, when the compressor 19 is in a non-actuated state, the electric heater 15 is turned on to start heating of the storage chamber 9 (steps S6 and S7). -9- This paper size is in accordance with Chinese National Standard (CNS) A4 (210X297 mm) f Please read the notes on the back before filling out this page}-Order printed by the Intellectual Property Bureau Employee Consumer Cooperative of the Ministry of Economy 499560 () On the other hand, it is determined whether the storage room temperature tr has become higher than the storage room upper limit temperature TRH, and when it becomes higher, the operation of the electric heater 15 is stopped (steps S8 and S9). By performing the above steps S1 to S9, it is possible to maintain the temperature of the refrigerant at a predetermined freezing maintaining temperature without increasing the power consumption, while maintaining the temperature of the storage compartment to a predetermined temperature. The changes in the storage room temperature TR of the control device 34 and the operating conditions of the electric heater 15, the refrigerant temperature TF, and the operating conditions of the compressor 19 according to this will be described with reference to FIG. 5, which illustrates the control Timing flowchart of the operation of the device. As shown in Fig. 5, the compressor 19 is controlled so that the refrigerant temperature TF is managed to be maintained within the range of the refrigerant freezing lower limit temperature TFIj and the refrigerant freezing upper limit temperature TFH. On the one hand, the electric heater 15 is usually controlled so that the storage room temperature TR is managed and maintained within a range between the storage room lower limit temperature TRL and the storage room upper limit temperature TRH. However, the storage compartment temperature TR is lower than the storage compartment lower limit temperature TRlj. Normally, even when the electric heater 15 is activated, the electric heater 15 is not activated when the compressor 19 is activated. Then, the heater 15 is operated after the compressor 19 is stopped. In other words, the refrigerating operation based on the compressor 19 is prioritized over the heating operation of the electric heater 15. This prevents the compressor 19 and the electric heater 15 from operating at the same time, thereby preventing an increase in power consumption. In this way, according to the cold storage refrigerator according to the present embodiment, since the operation control system of the electric heater 15 for heating the storage room and the temperature management of the refrigerator 13 are performed in combination, the compressor 19 and the electric heater can be controlled. 1 5 Do not act at the same time. This can prevent the increase in power consumption due to the simultaneous operation of both, and -10- 499560 V. Description of the Invention (1) Since the electric heater 15 is arranged near the refrigerator 1 3, the electric heater 1 5 Used for both heating and defrosting of the storage room 9. As a result, cost and weight can be reduced in accordance with the number of parts, and at the same time, the volume of the storage room 9 can be increased or the size of the cold storage refrigerator 1 can be reduced. Moreover, in this embodiment, although the electric heater 15 is used for both heating and defrosting of the storage room 9, a heating device for heating and a defrosting heating for the storage room 9 may be separately provided. In this case, the heating device for heating the storage room 9 is preferably provided in the storage room 9 on, for example, a wall surface or a bottom surface of the storage room 9. As described in detail above, according to the invention in the scope of patent application No. 1, by combining the operation of the heating device based on the storage room temperature management device and the refrigerant temperature management device, the heating device and the cooling device can be controlled at the same time. Act. This prevents an increase in power consumption due to the simultaneous operation of the heating device and the cooling device. According to the invention in the second scope of the patent application, the heating device is operated only when the cooling device is inactive according to the refrigerant temperature management device. Since the heating device and the cooling device do not operate at the same time, it can be reliably prevented. The heating device and the cooling device are operated at the same time to increase power consumption. Furthermore, according to the invention in the third scope of the patent application, since the heating device is installed near the refrigerating agent, the heating device can be used as a defrosting device to remove the Therefore, it is possible to reduce the cost and weight according to the number of parts, and to increase the volume of the storage compartment 9 or miniaturize the cold storage refrigerator 1.
