Title:
極低温混合冷媒システムのフリーズアウト防止方法
Document Type and Number:
Japanese Patent JP4277078
Kind Code:
B2
Abstract:
Refrigerant freezeout is prevented by the use of a controlled bypass flow that causes a warming of the lowest temperature refrigerant in a refrigeration system that achieves very low temperatures by using a mixture of refrigerants comprising at least two refrigerants with boiling points that differ by at least 50° C. This control capability enables reliable operation of the very low temperature system.
