Since the transport box is brought out outdoors, the environmental temperature may change significantly depending on the season, area, etc., and the environmental temperature may be lower than the internal temperature of the transport box. In addition, when the transport box is brought out from the room where the room temperature is maintained to the outside of the extremely cold or extremely hot environment, the environmental temperature may be rapidly increased or decreased.

- the ambient temperature sensor 30 By installing the ambient temperature sensor 30 in the vicinity of the outer air flow inlet in the air-permeable component storage unit 3, the ambient temperature sensor 30 is not affected by the minute temperature change of the outside air, and is not affected by the cold heat or heat of the inside of the refrigerator. This enables accurate temperature measurement.
- the internal battery temperatures Tb from 68 are input to the central control unit 62, respectively.
- symbol Tin in a figure is the center part temperature in a refrigerator.
- the heat conduction of the internal heat transfer container 8 itself and the convection of the internal air on the surface of the internal heat transfer container 8 are used as main heat equalizing means, so the temperature inside the internal storage Control can be performed by detecting the temperature of the heat transfer container 8.
- FIG. 20 is a temperature characteristic diagram for explaining it.

- the temperature (Tcp, Tin, Tx, Tcd) fluctuates at each location and is difficult to stabilize. This is the heat uniformity in the storage with respect to the main part in the storage (in the present embodiment, the side opposite to the side on which the temperature sensor 29 for feeding control of the storage heat transfer container 8 is installed) Even if the temperature is increased, heat transfer takes time at a distant part away from the electronic cooling unit 10. Therefore, if the temperature is controlled based on the temperature of the far part separated from the electronic cooling unit 10, the temperature fluctuation near the electronic cooling unit 10 is large. In order to
- FIG. 6 is a temperature characteristic diagram when the power output to the electronic cooling unit 10 is controlled and the power output is corrected with the detected environmental temperature Ta.
- the detection signal of the environmental temperature sensor 30 is input to the power supply control board 25, and the Peltier element 20 is supplied with electric power in accordance with the environmental temperature so that the inside temperature is stabilized to the preset temperature set in advance. Adjust the current value.
- the temperature Tcp for feeding control enters the first temperature zone (2 to 6 ° C.), which is the temperature target, and then the temperature at the central portion Tin and the temperature Tx at the bottom of the heat transfer vessel 8 at the bottom of the heat transfer vessel 8 Is also controlled within the control temperature zone, and it can be seen that stable control is possible.
- the feed control temperature Tcp for controlling the inside temperature constantly is constant, and the amount of power supplied to the electronic cooling unit 10 may be controlled so that the temperature can be maintained. . Therefore, when the change of the environmental temperature Ta is small, the control to correct the environmental temperature Ta is stable based on the temperature Tcp for feeding control.
- the internal temperature is influenced by the environmental temperature Ta, and when the environmental temperature Ta is high, the internal temperature also increases, and when the environmental temperature Ta is low, the internal temperature also decreases. Therefore, if the target power supply control temperature Tcp for controlling the temperature inside the storage is kept constant, the temperature inside the storage changes according to the environmental temperature Ta.
- FIG. 22 shows the case where the target power feeding control temperature Tcp set under the condition of environmental temperature Ta 25 ° C. is controlled without changing (fixed), and the temperature in the storage (Tcp) when the environmental temperature Ta gradually increases , Tin, Tx, Tcd) is a temperature characteristic chart in which changes were examined.
- the actual temperature Tcp for feed control As the environmental temperature Ta rises, the actual temperature Tcp for feed control, the temperature in the central part Tin in the cold storage, the temperature in the cold storage equivalent Tx, and the temperature Tcd in the bottom of the heat transfer vessel 8 also rise As the environmental temperature Ta exceeds 30 ° C., the internal temperature exceeds 6 ° C., which is the upper limit value of the first temperature zone.
- FIG. 23 shows the case where the polarity of the voltage applied to the electronic cooling unit 10 is reversed by the polarity reversal control unit 31 (see FIG. 19) when the environmental temperature becomes lower than the temperature inside the cold storage and used in the heating mode It is a temperature characteristic figure which shows change of store interior temperature and environmental temperature.
- Th in the figure indicates the temperature outside the cold storage.
- the fan 61 (see FIG. 19) is stopped to save power, but when returning from the heating mode to the cooling mode, it is indicated by A part in FIG.
- the temperature of the outside heat exchanger unit Th may change discontinuously. Due to this influence, the inside temperature (Tcp, Tin, Tx, Tcd) also largely changes.
- FIG. 24 shows the same as in FIG. 23 when the ambient temperature is lower than the internal temperature, the polarity of the voltage applied to the electronic cooling unit 10 is reversed, and the internal temperature and environment when used in the heating mode It is a characteristic view showing change of temperature.
- the inside temperature (Tcp, Tin, Tx, Tcd) of the inside of the refrigerator is continuously compared with that of FIG. 23 by continuously rotating the fan 61 outside the refrigerator (see FIG. 19) even when switching to the heating mode. It is stable within the specified temperature range.
- FIG. 25 is a temperature characteristic diagram showing changes in the internal temperature and the environmental temperature when the actual environmental temperature (displayed as outside air) changes significantly.
- Ta in the figure is the environmental temperature detected by the environmental temperature sensor 30.
- the reaction is delayed. .
- the environmental temperature sensor 30 is installed in the storage unit 3 whose response to the environmental temperature is a little slow. The sensitivity is slightly reduced.
- the temperature when the temperature changes rapidly, the temperature does not follow the response immediately, and the temperature inside the chamber fluctuates.
- the internal temperature does not exceed the specified temperature range, but it may be considered that the temperature may deviate depending on the conditions.
- the external heat exchanger section temperature sensor 67 for detecting the external heat exchanger section temperature Th is also associated with the fact that it is installed on the intake side as shown in FIG. The ability to follow changes in For this reason, it is effective as a temperature sensor for catching the change point which a rapid temperature change produces.
- the determination of the sudden change in the outside air is based on the external heat control temperature based on the power supply control temperature Tcp, rather than the control that corrects the environmental temperature Ta based on the power supply control temperature Tcp.
- the temperature control in the storage is more stable in the case of the control that adds the control to correct the exchange unit temperature Th.
- the heat radiation performance is improved. It is possible to detect that the internal pressure has dropped and the like before the internal temperature can not be maintained, and to notify the operator by the alarm unit 57 (see FIG. 18). Furthermore, it is also possible to monitor the operating state of the fan 61 by measuring the outside heat exchanger unit temperature Th.
- the change of the environmental temperature changes the inside temperature (Tcp, Tx, Tcd) and the inside temperature distribution.
- FIG. 26 shows the tendency. As shown in FIG. 26, when the environmental temperature is 35 ° C., the inside temperature (Tcp, Tx, Tcd) and the inside temperature distribution (the range surrounded by long circles) are within the specified temperature (in the case of this embodiment, 2 to) 6 ° C).
- the temperature distribution (the temperature Tcp for feeding control) deviates from the specified temperature range as shown by the dotted line when the environmental temperature rises further.
- the interior equivalent temperature Tx indicates a temperature close to the interior center portion, and has a value close to 3 ° C. Therefore, when the environmental temperature sensor 30 detects that the environmental temperature Ta has become 35 ° C. or higher, the internal equivalent temperature Tx is shifted upward (for example, shifted from 3 ° C. to 4 ° C.) as indicated by the arrow. When control is performed as the equivalent temperature Tx 4 ° C.), the power supply control temperature Tcp is also shifted upward on average, and the temperature distribution can be kept within the specified temperature range.
- the control for correcting the difference between the set in-chamber temperature Tin and the in-chamber equivalent temperature Tx when the in-chamber equivalent temperature Tx deviates from the target temperature with respect to the environmental temperature Ta is aimed at the in-chamber temperature distribution in a wide outside temperature range. It is effective to store in the temperature zone.
- the temperature of the storage section 3 In the winter, when the transport box is brought out outdoors for use at 0 ° C. or lower for transportation, the temperature of the storage section 3 often becomes negative.
- the inventors conducted a test and confirmed that when the ambient temperature Ta is -11 ° C., the temperature of the storage unit 3 has also dropped to near -10 ° C.
