Scroll Compressor Multi-Port Injection for Suction Flow and Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing air conditioner systems face performance limitations due to inadequate refrigerant flow rates, particularly when ambient air conditions are extreme, as the position of refrigerant injection holes in scroll compressors significantly affects suction and compression processes, leading to reduced efficiency.
Innovation Solution
The implementation of a scroll compressor with three distinct refrigerant injection paths and corresponding introduction ports, each injecting refrigerant at different intermediate pressures at specific angles relative to the compressor's rotation, optimizing the injection timing and position to enhance flow rates and reduce internal pressure resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a compressor having a large capacity is provided to increase performance, then the cooling or warming performance is improved, but the manufacturing or installation cost increases
Solution Approach 1:
The patent changes the parameters of refrigerant injection by providing multiple injection ports at different positions and angles within the compression chamber. This allows optimization of refrigerant flow characteristics and compression efficiency without increasing compressor capacity, thereby improving performance while avoiding the cost increase associated with larger compressors
2Force
If the injection hole is located at a predetermined position, then refrigerant injection is performed before suction is completed, but the pressure in the suction chamber increases and the flow rate of suctioned refrigerant is reduced
Solution Approach 1:
The patent applies local quality by providing multiple injection ports at different positions and angles within the compression chamber. Each port is strategically positioned to inject refrigerant at optimal locations without interfering with the suction process, thereby maintaining high suction flow rate while achieving effective refrigerant injection
3Force
If the injection hole is located at another predetermined position, then refrigerant injection is performed after suction is completed, but the internal pressure of the compression chamber is already increased and the injection flow rate is reduced
Solution Approach 1:
The patent employs dynamics by providing multiple injection ports at different angles (e.g., 0°, 60°, 120°) that are sequentially activated during the compression cycle. This dynamic approach ensures that refrigerant injection occurs at optimal pressure conditions throughout the compression process, maintaining high injection flow rate while adapting to changing chamber pressure

Function Achieved in This Case
This configuration increases refrigerant flow rates, improves cooling and warming performance, and reduces the power required for compression, thereby enhancing the overall efficiency and reliability of the air conditioner system.
Implementation Method 1
a compression chamber (181, 183) formed by engagement between the fixed scroll wrap (123) and the orbiting scroll wrap (132), wherein a volume of the compression chamber (181, 183) is reduced due to an orbiting motion of the orbiting scroll (130)
Implementation Method 2
a first introduction part (71) provided at a first side of the fixed scroll (120) to inject the first refrigerant (70) into the compression chamber (181, 183)
