Solution Overview
Problem
Current azeotropic compositions and azeotropic-like compositions for refrigeration and cleaning applications face challenges in maintaining a consistent composition ratio between the liquid and gas phases, leading to inefficiencies and environmental concerns due to volatility and flammability.
Innovation Solution
A specific azeotropic-like composition comprising 2-chloro-1,3,3,3-tetrafluoropropene (HCFO-1224xe) and 1-chloro-3,3,3-trifluoropropene (HCFO-1233zd) is developed, which maintains a stable composition ratio in both phases, reducing environmental impact and flammability, and is suitable for use as a washing detergent, solvent, foaming agent, coolant, and heat transfer medium.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If conventional azeotropic compositions are used, then refrigeration and cleaning performance is achieved, but composition ratio consistency between liquid and gas phases deteriorates due to volatility
Solution Approach 1:
The patent changes the chemical composition parameters by using specific HFO compounds (1-chloro-3,3,3-trifluoropropene and 2-chloro-1,3,3,3-tetrafluoropropene) with controlled ratios to form an azeotropic mixture that maintains consistent composition between phases, thereby reducing volatility-related composition changes
Solution Approach 2:
The patent creates a composite azeotropic mixture combining two different HFO compounds in specific proportions, where the synergistic interaction between components achieves both refrigeration performance and composition stability that neither component could achieve alone
2Productivity
If conventional azeotropic compositions are used, then cleaning performance is achieved, but flammability increases
Solution Approach 1:
The patent modifies the chemical composition by selecting specific HFO compounds and their ratios to achieve optimal balance between cleaning performance and flammability reduction, utilizing the unique properties of each component
Solution Approach 2:
The patent converts the potential harm of flammability into a benefit by carefully selecting component ratios that reduce flammability while maintaining or enhancing cleaning performance, effectively transforming a harmful property into a controlled and beneficial characteristic
