Experimental research of a 173K three stage auto-cascade refrigeration system

摘要

A single-compressed and three-stage segregating auto-cascade refrigeration system was developed in this paper. System fundamentals are introduced. Circular flow of each component in the cycle was calculated with the series heat balance method, the feasibility was pointed out for selecting the proportion of mixture in the manufacturing process of actual device by calculating. The effects of operating temperatures for cryogenic tank on the temperature for evaporator, the low side of regenerator, before throttling and the pressure are slight when the state of the system is steady.
