Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If HFCs are used to achieve zero ODP, then ozone depletion is eliminated, but global warming potential increases significantly
Solution Approach 1:
The patent changes the chemical composition parameters by using hydrofluorocarbon blends with specific ratios of HFC-134a, HFO-1234yf, and HFO-1225ye, achieving a balance between low GWP and acceptable refrigeration performance while maintaining zero ODP
Solution Approach 2:
The invention creates a composite refrigerant blend combining three different chemical components (HFC-134a, HFO-1234yf, HFO-1225ye) to achieve properties that individual components cannot provide alone, specifically balancing cooling capacity with low global warming potential
2Productivity
If flammable gases like propane or butane are added to increase cooling capacity, then refrigeration efficiency improves, but flammability increases
Solution Approach 1:
The patent modifies the compositional parameters by using HFO-1234yf and HFO-1225ye which have lower flammability characteristics compared to hydrocarbons, while maintaining adequate cooling capacity when blended with HFC-134a in specific ratios
3Object-generated harmful factors
If refrigerant leakage is reduced to minimize environmental impact, then global warming contribution decreases, but system reliability requirements increase
Solution Approach 1:
The use of HFO-1234yf and HFO-1225ye components creates a chemically stable refrigerant blend that is less reactive and more stable under various operating conditions, reducing the risk of degradation and leakage while maintaining system reliability
