Solution Overview
Problem
Existing fluid compression devices, such as thermal compressors, face challenges in complex and costly sealing and control of pre-compression pistons, as well as thermodynamic conditions that make it difficult to arrange multiple compression stages in series.
Innovation Solution
The compression device connects the upstream end of the supply pipe directly to the first end of the compression chamber without a pre-compression chamber, incorporating non-return valves and a regenerator with a heat exchanger, allowing for efficient fluid compression and enabling multiple compression stages in series by varying temperature conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a pre-compression chamber is used in the compression device, then the compression process can be divided into stages, but the sealing and control become complex and expensive
Solution Approach 1:
The patent removes the pre-compression chamber from the system, extracting the problematic component that caused sealing and control complexity. The compression process is simplified by eliminating the need for separate pre-compression staging, while still achieving efficient compression through the main compression chamber with direct supply pipe connection.
Solution Approach 2:
The patent segments the compression process into distinct functional zones within the compression chamber, using the piston to create separate compression and expansion zones. The supply pipe connects directly to the compression chamber, creating clear functional separation between intake, compression, and discharge paths, eliminating the need for separate pre-compression chamber sealing.
2Productivity
If a pre-compression chamber is used, then compression stages can be arranged, but the thermodynamic conditions make it difficult to arrange multiple compression stages in series
Solution Approach 1:
The patent utilizes temperature parameter changes to enable multiple compression stages in series. The compression chamber maintains variable temperature conditions through the piston cycle, and the regenerator exploits these temperature variations to facilitate efficient heat exchange. This allows the discharge of one stage to serve as the intake for the next stage, creating a versatile multi-stage configuration.
Solution Approach 2:
The regenerator acts as an intermediary between compression stages, using heat exchange to bridge the thermodynamic gap. It captures heat from the hot discharge side and transfers it to the cold intake side, enabling efficient coupling of multiple compression stages in series without requiring complex inter-stage cooling systems.
3Device complexity
If the supply pipe connects directly to the compression chamber without a pre-compression chamber, then sealing and control are simplified, but the compression ratio may be reduced
Solution Approach 1:
The patent employs dynamic piston movement to create varying pressure conditions within the compression chamber. The piston dynamically adjusts the compression ratio during its cycle, and the regenerator dynamically exchanges heat based on the instantaneous temperature and pressure conditions. This dynamic operation allows direct connection of the supply pipe while maintaining effective compression ratios through the full piston stroke.
Solution Approach 2:
The patent ensures continuous compression action by maintaining the piston in a continuous compression stroke from the supply pipe connection point to the discharge point. The regenerator continuously exchanges heat during the piston movement, ensuring that the compression process remains continuous and efficient without interruption from separate pre-compression chambers.
