Title:
FLUID TEMPERATURE CONTROL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/162723
Kind Code:
A1
Abstract:
A fluid temperature control system according to an embodiment of the present invention cools a fluid by means of a multiple-stage refrigeration system 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-stage refrigeration system 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) form 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) form a second cascade condenser (CC2). A middle-temperature-side refrigerant and a low-temperature-side refrigerant are identical refrigerants. A fluid circulated by a fluid circulation device is cooled by the medium-temperature-side first evaporator (204) of the medium-temperature-side refrigerator (200) and is then cooled by a low-temperature-side evaporator (304) of the low-temperature-side refrigerator (300).
