- the present invention relates to a circulating cooling system for a cryogenic cable such as a superconducting cable.
- Cryogenic cables such as superconducting cables are cooled by a refrigerant such as liquid nitrogen or liquid helium.
- a refrigerant such as liquid nitrogen or liquid helium.
- a circulating cooling system a system described in JP-A-8-148044 is known. ing.
- This circulation cooling system is a cooling system in which the circulation circuit of the refrigerant is a closed circuit and can be circulated in a state without vaporizing the refrigerant.
- FIG. 2 is a schematic view thereof, in which a reservoir unit 30 that stores the refrigerant 33, a pressure-feed pump 31 that pumps the refrigerant 33, a pressure control mechanism 36 that holds the inside of the reservoir unit 30 at a predetermined pressure, and a refrigerant A heat exchange unit 32 that cools 33 to a predetermined temperature, a valve unit 34 that divides the refrigerant 33 into cables 35 (three cables are present, each cable is not shown), etc. .

- Patent Document 1 JP-A-8-148044 (Claims and Figure 1)
- the reservoir unit 30 when the cable 35 is used as a starting point, the reservoir unit 30 is located upstream of the circulation circuit, and the refrigerant 33 delivered from the reservoir unit 30 is heated. After being cooled to the specified temperature by the replacement unit 32, it is sent to the cable 35 side. That is, since the refrigerant 33 returns to the reservoir unit 30 after cooling the cable 35, the temperature of the refrigerant 33 rises due to heat generated by the cable 35, and the volume of the refrigerant 33 increases due to thermal expansion. [0006] The volume of the refrigerant 33 also changes in response to the change in the amount of heat generated in the cable 35. In addition, when a large heat generation in the cable 35 is expected, the force that needs to sufficiently cool the refrigerant 33 correspondingly, the refrigerant 33 contracts conversely and its volume decreases.
- the refrigerant 33 expands and contracts by the temperature change of the refrigerant 33, and the liquid volume changes.
- each component other than the reservoir unit 30 such as the cooling part of the cable 35 and the piping Since the volume of the refrigerant is constant, it is necessary to absorb the amount of change in the refrigerant liquid by the volume in the reservoir unit 30. Therefore, the refrigerant storage volume of the reservoir unit 30 must be designed so as to be able to absorb the change in the refrigerant liquid amount in the circuit, and as a result, the reservoir unit 30 must have a large capacity.
- the reservoir unit 30 in order to keep the amount of refrigerant in the reservoir unit 30 constant, it is necessary to perform adjustment work by providing a mechanism for adjusting the amount of refrigerant.
- the reservoir unit needs to have a large volume in consideration of this volume expansion and contraction, or has a large capacity.
- the refrigerant amount adjustment mechanism was required.
- the present invention solves the problems of the conventional circulating cooling system described above, can reduce the size of the reservoir unit, and does not require a mechanism for adjusting the amount of refrigerant in the reservoir unit or adjustment work.
- An object is to provide a circulating cooling system.
- the cryogenic cable circulation cooling system of the present invention is characterized by having a refrigerant temperature adjustment mechanism for keeping the amount of refrigerant in the reservoir unit constant, and this feature achieves the object described above. It is.
- the cryogenic cable circulation cooling system includes a reservoir unit that stores the refrigerant, and a cable cooling unit that cools the cable with the refrigerant sent from the reservoir unit.
- a cryogenic cable circulation cooling system that circulates the refrigerant sent out from the cable cooling unit again to the reservoir unit, and has a refrigerant temperature adjustment mechanism for keeping the amount of refrigerant in the reservoir unit constant. It is characterized by.
- the refrigerant temperature adjustment mechanism includes a refrigerant It may consist of a sensor that detects temperature and a heat exchange unit that adjusts the cooling capacity according to the detection result of the sensor.
- the sensor for detecting the refrigerant temperature is
- the heat exchange unit may be located between the refrigerant outlet of the cable cooling section and the refrigerant return port to the reservoir unit.
- the cooling capacity of the heat exchange unit may be adjusted by adjusting the power for operating the heat exchange unit or the power supply frequency.
- the cryogenic cable circulation cooling system has a refrigerant temperature adjustment mechanism for keeping the refrigerant amount in the reservoir unit constant, so that the reservoir unit absorbs the volume change of the refrigerant. This makes it possible to reduce the size of the reservoir unit that does not require additional volume. In addition, a mechanism for adjusting the refrigerant volume in the reservoir unit and adjustment work are not required.
- the sensor for detecting the refrigerant temperature is in the vicinity of the outlet of the cable cooling unit and the heat exchange unit is installed between the refrigerant outlet of the cable cooling unit and the refrigerant return port to the reservoir unit. Therefore, it is possible to adjust the cooling capacity of the heat exchange unit more reliably in response to changes in the heat generation of the cable, and the effect of the change in the volume of the refrigerant due to the heat generation in the cable directly affects the reservoir unit side. Therefore, the amount of refrigerant in the reservoir unit can be kept constant more accurately.
- FIG. 1 is a schematic view showing an example of a circulating cooling system for a cryogenic cable according to the present invention.
- FIG. 2 is a schematic view showing an example of a conventional cryogenic cable circulation cooling system. Explanation of symbols [0019] 1, 30 Reservoir unit, 2, 32 Heat exchange unit, 3, 34 Valve unit, 4 Cable cooling part, 5 Sensor, 7, 31 Pressure feed pump, 8 Bypass valve, 9, 36 Pressure control mechanism, 10 Refrigerator , 11 Cold head, 12 Flow meter, 13 Flow control valve, 14 Bypass valve, 15, 16 Piping, 18 Vacuum insulated container, 20 Safety valve,
- the refrigerant temperature adjustment mechanism for keeping the refrigerant amount in the reservoir unit constant has a function of keeping the refrigerant temperature in the system constant, and a sensor for detecting the refrigerant temperature and a detection result of the sensor
- a typical example is a heat exchange unit that adjusts the cooling capacity in response to. In response to the change in the refrigerant temperature detected by the sensor, the cooling capacity of the heat exchange unit is increased (when the temperature is lowered) or decreased (when the temperature is raised) to keep the refrigerant temperature constant.
- the type of the sensor that detects the refrigerant temperature is not limited as long as it is capable of accurate and sensitive detection even at an extremely low temperature.
- it is the change in the amount of heat generated in the normal cable that has the greatest influence on the change in refrigerant temperature. Therefore, it is preferable to install the sensor in the vicinity of the outlet of the cable cooling section because a change in the amount of heat generated in the cable can be quickly detected and the refrigerant temperature can be adjusted with high sensitivity.
- the type of the heat exchange unit is not limited as long as it has sufficient cooling capacity and can adjust the cooling capacity corresponding to changes in the refrigerant temperature.
- the method for adjusting the cooling capacity is not particularly limited, and is a method often used in conventional cooling systems, that is, a heat exchange unit having a full power that is equal to or greater than the power corresponding to the expected maximum value of the refrigerant temperature change. -If the refrigerant is always operating at full power and the refrigerant temperature is too low, it can be adjusted by heating with a heater in the heat exchange section of the heat exchange unit. However, if the cooling capacity is adjusted by adjusting the power for operating the heat exchange unit or the power supply frequency, heating by the heater becomes unnecessary, which is preferable because it saves energy (power consumption) required for cooling.
- the adjustment of the power supply frequency is performed by, for example, an inverter. Cooling capacity of heat exchange unit The force depends on the frequency. For example, from 60Hz operation to 30Hz operation, the cooling capacity is 1Z2.
- the refrigerant is sent from the reservoir unit to the cable cooling section.
- the sensor for detecting the refrigerant temperature is near the outlet of the cable cooling section, heat exchange is performed.

When the temperature near the outlet of the cable cooling section where the heat generated in the cable is large, the cooling capacity of the heat exchange unit can be increased and the rise in the refrigerant temperature can be suppressed.
- the cable cooling section that is, the heat generating section is located downstream of the heat exchange unit
- the adjustment of the refrigerant temperature that quickly responds to the change in the amount of heat generated in the cable, and hence the change in the refrigerant temperature. It is not possible to make quick adjustments corresponding to changes in the volume of the refrigerant. In other words, even if the refrigerant temperature changes due to changes in the amount of heat generated by the cable, and as a result the refrigerant volume increases or decreases, it is not possible to immediately adjust the temperature of the refrigerant itself whose volume has increased or decreased. Because it is not possible, it cannot respond quickly to changes in the volume of the refrigerant. As a result, adjustment with high sensitivity becomes difficult.
- the heat exchange unit is installed between the refrigerant outlet of the cable cooling unit and the refrigerant return port to the reservoir unit.
- a particularly preferred mode is when the sensor for detecting the refrigerant temperature is in the vicinity of the outlet of the cable cooling unit, and the heat exchange unit is installed between the refrigerant outlet of the cable cooling unit and the refrigerant return port to the reservoir unit. is there.
