Abstract
A cooling apparatus comprises a main refrigerator having a refrigerant-filled chamber, a sub-refrigerator connected parallel to the main refrigerator and having a refrigerant-filled chamber, switch control means for controlling the switching operation between the supply of a refrigerant used in the main refrigerator to the sub-refrigerator, and the stop of the supply of the refrigerant, on the basis of predetermined conditions.
Claims24
A cooling apparatus comprising:
- a first refrigerator supplied with a refrigerant;
- a second refrigerator connected parallel to the first refrigerator for receiving a flow of the refrigerant from the first refrigerator;
- and
- a controller for regulating the flow of the refrigerant from the first refrigerator to the second refrigerator in accordance with a selected condition.
A superconducting magnet apparatus comprising:
- a superconducting coil unit;
- and
- a cooling unit for cooling the superconducting unit, including a first refrigerator supplied with a refrigerant, a second refrigerator connected parallel to the first refrigerator for receiving a flow of the refrigerant from the first refrigerator, and a controller for regulating the flow of the refrigerant from the first refrigerator to the second refrigerator in accordance with a selected condition.
A cooling apparatus comprising:
- a first refrigerator;
- a second refrigerator connected parallel to the first refrigerator for circulating a refrigerant received from the first refrigerator;
- a valve through which the second refrigerator is connected parallel to the first refrigerator;
- and
- a controller for controlling the valve so as to regulate a flow of the refrigerant between the first and second refrigerators.
A superconducting magnet apparatus comprising:
- a superconducting coil unit;
- and
- a cooling unit for cooling the superconducting coil unit, including a first refrigerator, a second refrigerator connected parallel to the first refrigerator for circulating a refrigerant received from the first refrigerator, a valve through which the second refrigerator is connected parallel to the first refrigerator, and a controller for controlling the valve so as to regulate a flow of the refrigerant between the first and second refrigerators.
