Cryogenic Storage Enclosure With Internal Condenser Overflow Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cryogenic separation systems face inflexibility and inefficiency due to the need for multiple dedicated units and equipment, which complicates refrigeration control and operation, particularly in cold boxes where liquid level variations affect refrigeration supplements and cycles.
Innovation Solution
A single pressure vessel serves both as a storage for cooling capacity and houses a column condenser, with cryogenic liquid overflowing around the condenser, allowing for flexible operation and standardization by regulating energy exchange through pressure adjustments, and providing a reserve for liquid level regulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple dedicated units are used for refrigeration control, then refrigeration balance can be controlled, but device complexity increases and flexibility decreases
Solution Approach 1:
The patent combines the refrigeration storage function and condenser function into a single pot, eliminating the need for multiple dedicated units. The pot serves dual purposes: storing liquid refrigerant and housing the condenser, thereby reducing device complexity while maintaining refrigeration control capability
Solution Approach 2:
The single pot is designed to perform multiple functions simultaneously - it acts as both a storage vessel for cryogenic liquid and as a housing for the condenser. This multi-functional design reduces the number of components needed while maintaining system reliability for refrigeration balance control
2Reliability
If capacity is dedicated to specific functions, then function performance is optimized, but adaptability decreases and additional equipment is required
Solution Approach 1:
The single pot is designed as a universal component that can accommodate different operational requirements. It serves as both storage and condenser housing, allowing the system to adapt to various operational modes without requiring additional dedicated equipment for each function
3Reliability
If multiple pots are used for refrigeration capacity, then refrigeration control is achieved, but operational flexibility is hampered
Solution Approach 1:
The patent merges multiple refrigeration control functions into a single integrated pot system. The single pot with its internal condenser provides both storage capacity and condensation function, simplifying operation while maintaining refrigeration control through the unified design

AI summary
The invention relates to a liquid storage enclosure (C) including a chamber (21), a heat exchanger (3) disposed inside the chamber and a barrier (5) dividing the chamber into two parts. The heat exchanger is located in the first part (A) and the second part (B) is disposed around the first part. The barrier is sealingly attached to the base of the chamber, but the height of the barrier is smaller than that of the chamber. The invention also includes means (15, 17, 19) for discharging liquid into the first part of the chamber, means (7, 9, 11) for releasing liquid from the second part of the chamber and means for conveying liquid to the exchanger and releasing a fluid from the exchanger.
