Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If carbon dioxide is used as a refrigerant in a supercritical state to generate high pressures and velocities for efficient power production, then power production efficiency is improved, but sonic booms and vibrations may occur which could be catastrophic to the system
Solution Approach 1:
The ejector is designed with specific geometric parameters (throat area, exit area, length, and contour shape) that are optimized to control the expansion and acceleration of supercritical carbon dioxide. By carefully selecting these parameters, the system achieves high-velocity flow for power production while maintaining subsonic conditions throughout the ejector, preventing sonic booms and vibrations that would compromise system safety.
2Productivity
If high-pressure and high-velocity fluid flows are generated from the ejector for efficient turbine rotation, then power production is improved, but components must withstand extreme pressures of 74 atmospheres and above
Solution Approach 1:
The system operates carbon dioxide in a supercritical state above its critical point (74 atmospheres pressure and 31.1 Celsius temperature), which fundamentally changes the fluid's properties. This state allows for high-density, high-velocity flow that efficiently drives the turbine while the continuous phase state reduces shock loads on components compared to traditional two-phase flow systems.
3Object-affected harmful factors
If carbon dioxide is used as a refrigerant alternative to fluorocarbons, then environmental friendliness is improved, but high-pressure containment requirements increase
Solution Approach 1:
The system utilizes the phase transition properties of carbon dioxide by operating it in a supercritical state. The ejector is specifically designed to handle supercritical fluid dynamics, where the fluid exhibits properties of both liquids and gases. This phase state allows carbon dioxide to achieve high pressures and velocities necessary for power production while maintaining environmental benefits of zero ozone depletion potential.

AI summary
Refrigeration cycle ejector power generator makes use of refrigerant in a refrigeration cycle to feed an ejector or injector within the refrigeration cycle causing the ejector to fire refrigerant at extremely high pressures and velocities into a turbine fan or blade that is sealed inside the refrigeration system and is connected to a generator in order to generate electricity. Refrigeration cycle ejector power generator comprises: a condenser, an expansion valve, an evaporator, a compressor, an ejector valve, a first ejector, a turbine, and a controller or computer. Refrigeration cycle ejector power generator is a refrigeration cycle with at least one ejector positioned in the refrigeration cycle that emits refrigerant at a high pressure and high velocity that is directed at a turbine, causing it to rotate, where this rotational energy may be used to turn a generator, thereby generating electricity.
