Abstract: A fluid temperature control system according to an embodiment cools a fluid by means of a multiple refrigeration apparatus including a high-temperature-side refrigerator, a medium-temperature-side refrigerator and a low-temperature-side refrigerator. The medium-temperature-side refrigerator in the multiple refrigeration apparatus has a medium-temperature-side first evaporator and a medium-temperature-side second evaporator. A high-temperature-side evaporator of the high-temperature-side refrigerator and a medium-temperature-side condenser of the medium-temperature-side refrigerator constitute a first cascade condenser. The medium-temperature-side second evaporator of the medium-temperature-side refrigerator and a low-temperature-side condenser of the low-temperature-side refrigerator constitute a second cascade condenser. The medium-temperature-side refrigerant and the low-temperature-side refrigerant are the same refrigerant.

Abstract: A temperature-controlled fluid circulation apparatus includes a flow path through which a fluid controlled by a temperature control unit is circulated via a fluid supply target; a three-way valve in the flow path downstream of the fluid supply target and upstream of a temperature control position by the temperature control unit, a part between two out of three ports constituting a part of the flow path; and a bypass flow path branching from the flow path downstream of the temperature control position by the temperature control unit and upstream of the fluid supply target, to be connected to one remaining port out of the three ports of the three-way valve. A pressure of the fluid flowing through the flow path at a position that is downstream of the fluid supply target and upstream of the three-way valve is detected by a pressure sensor.

Abstract: A fluid temperature control system cools a fluid by means of a multiple refrigeration apparatus including a high-temperature-side refrigerator (100), a medium-temperature-side refrigerator (200) and a low-temperature-side refrigerator (300). The medium-temperature-side refrigerator (200) in the multiple refrigeration apparatus has a medium-temperature-side first evaporator (204) and a medium-temperature-side second evaporator (224). A high-temperature-side evaporator (104) of the high-temperature-side refrigerator (100) and a medium-temperature-side condenser (202) of the medium-temperature-side refrigerator (200) constitute a first cascade condenser (CC1). The medium-temperature-side second evaporator (224) of the medium-temperature-side refrigerator (200) and a low-temperature-side condenser (302) of the low-temperature-side refrigerator (300) constitute a second cascade condenser (CC2). The medium-temperature-side refrigerant and the low-temperature-side refrigerant are the same refrigerant.

Abstract: In a first fluid circulation device, a heat exchanger, a tank that stores a first fluid liquefied by the heat exchanger, a first fluid pump that pumps the first fluid stored in the tank, a heater that heats the first fluid pumped from the first fluid pump, and a first fluid supply unit to which the first fluid is supplied from the heater are connected by a first pipe. A second fluid circulation device includes a cooler that cools a second fluid, causes the second fluid having been cooled by the cooler to circulate through a second pipe, and returns the second fluid to the cooler. The second pipe is connected to the heat exchanger and is connected to the tank and the first fluid pump, and the second fluid cools the first fluid in the heat exchanger, the tank, and the first fluid pump.

Abstract: A temperature control system includes: first and second refrigerator units; a first fluid flow apparatus that allows a first fluid to flow therethrough and that is cooled by the first refrigerator unit; a second fluid flow apparatus that allows a second fluid to flow therethrough and that is cooled by the second refrigerator unit; and a valve unit that is configured to allow the first fluid or the second fluid to selectively flow out therefrom. The first refrigerator unit has, in a medium-temperature-side refrigerator, a medium-temperature-side first expansion valve and a medium-temperature-side second expansion valve. A medium-temperature-side second evaporator corresponding to the medium-temperature-side second expansion valve and a low-temperature-side condenser of a low-temperature-side refrigerator constitute a cascade condenser.
