Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional compressors in cooling, refrigeration, and heat-pump systems lack efficient temperature-responsive mechanisms to manage operating temperatures effectively, leading to potential damage from high temperatures and reduced performance.
Innovation Solution
A thermally-responsive injector system is integrated into the compressor, utilizing a shape memory material biasing member within a valve assembly that changes position in response to temperature changes, allowing or inhibiting fluid injection into compression pockets to regulate temperature.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional compressors operate without thermally-responsive mechanisms, then the device complexity is reduced, but the reliability deteriorates due to potential damage from high temperatures
Solution Approach 1:
The compressor system performs self-regulation of temperature through the thermally-responsive valve assembly that automatically opens or closes based on compression chamber temperature, eliminating the need for external control systems or sensors while maintaining reliability
Solution Approach 2:
The valve assembly utilizes thermally-responsive biasing members whose physical properties (such as thermal expansion or shape memory effects) change with temperature, causing automatic position changes to regulate cooling fluid flow and maintain optimal operating temperature
2Temperature
If a thermally-responsive valve assembly is added to the compressor, then the temperature control capability is improved, but the device complexity increases
Solution Approach 1:
The valve assembly autonomously responds to temperature changes through thermally-responsive biasing members that automatically adjust valve position without requiring external control systems, sensors, or complex actuation mechanisms
Solution Approach 2:
The biasing members are configured to exploit thermal expansion or shape memory effects, where temperature-induced dimensional changes directly actuate the valve position to control cooling fluid injection into compression chambers
3Temperature
If cooling fluid is continuously injected into compression pockets, then the temperature is controlled, but the loss of energy increases
Solution Approach 1:
The thermally-responsive valve assembly provides periodic or on-demand cooling fluid injection only when compression chamber temperature exceeds optimal levels, rather than continuous injection, thereby reducing energy loss while maintaining effective temperature control
Solution Approach 2:
The system implements thermal feedback through thermally-responsive biasing members that sense compression chamber temperature and automatically adjust valve position to modulate cooling fluid flow, ensuring cooling is applied only when and where needed

AI summary
A compressor includes a housing, a partition, a first scroll, a second scroll, and a valve assembly disposed within the second scroll. The valve assembly includes a valve housing, a valve body, and a first biasing member configured to displace the valve body from a first position to a second position relative to the valve housing. When in the first position, the valve body inhibits fluid communication between a fluid source and one of a series of compression pockets formed by the first and second scroll. When in the second position, the valve body allows fluid communication between the conduit and one or more of the series of compression pockets. The valve body is displaceable between the first and second positions in response to a change in operating temperature of the compressor.
