Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a vacuum pump is used to remove air and moisture from the refrigerant circuit during installation, then the system reliability is improved by removing detrimental substances, but the device complexity and installation cost increase
Solution Approach 1:
The harmful substances (moisture, oxygen, nitrogen) are extracted from the refrigerant circuit using an adsorption device containing adsorption material, eliminating the need for vacuum pumping and simplifying the installation process while maintaining system reliability
Solution Approach 2:
An adsorption device is introduced as an intermediary component in the refrigerant circuit that passively removes detrimental substances through adsorption, replacing the active vacuum pumping process and reducing installation complexity
2Object-affected harmful factors
If a vacuum pump is required for installation, then moisture and oxygen are effectively removed from the refrigerant circuit, but the installation cost and maintenance requirements increase
Solution Approach 1:
The adsorption device uses relatively inexpensive adsorption material that can be easily replaced or regenerated, eliminating the need for expensive vacuum pumps and their ongoing maintenance, while still achieving effective removal of moisture and oxygen from the refrigerant circuit
3Object-affected harmful factors
If the adsorption device is placed in the liquid refrigerant portion, then moisture adsorption is enhanced, but the refrigerant flow is disrupted and system performance decreases
Solution Approach 1:
The adsorption device is specifically positioned in the gaseous refrigerant portion of the circuit where it can adsorb moisture without interfering with liquid refrigerant flow, optimizing both moisture removal efficiency and system productivity through localized functional placement
