Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing removal devices for refrigeration systems require additional pumps and valves for cleaning, as they rely on pressurized rinsing fluids to prevent condensable liquids from mixing, making the cleaning process cumbersome and inefficient.
Innovation Solution
The removal device features a pipeline assembly with inclined pipeline elements, allowing fluid to flow out by gravity when the outlet is open, eliminating the need for additional pumps or valves, and incorporating self-closing couplings and cooling fins for efficient heat transfer and assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If additional pumps and valves are used to pump refrigerant and cleaning gas through the pipelines, then the cleaning process can be performed, but the device complexity increases
Solution Approach 1:
The pipeline assembly is designed with an inclined arrangement that enables self-draining of fluid through gravity. The fluid outlet is positioned at the lowest point and the pipelines are inclined towards it, allowing complete fluid removal without requiring external pumps or valves. This self-service mechanism eliminates the need for additional equipment while maintaining effective cleaning capability.
Solution Approach 2:
The system uses gravitational potential energy by positioning the fluid outlet at the lowest point and inclining all pipeline elements towards it. This creates a natural flow path where fluid moves from higher to lower positions without requiring additional energy input from pumps, simplifying the overall system while maintaining cleaning effectiveness.
2Device complexity
If the pipeline assembly is designed with inclined elements for gravity-driven fluid flow, then the device complexity is reduced, but the manufacturing precision requirements increase
Solution Approach 1:
The patent specifies a concrete inclination angle parameter (α between 1° and 4°, preferably 2° to 3°, particularly 2.5°) that optimizes the balance between gravity-driven flow effectiveness and manufacturing feasibility. This parameterized approach provides clear design guidance while remaining practical for manufacturing, transforming an abstract design requirement into a actionable specification.

Function Achieved in This Case
This design enables complete and efficient fluid removal without manual intervention, simplifying the cleaning process and reducing the need for additional equipment, while maintaining effective refrigerant flow and heat transfer.
Implementation Method 1
the pipeline elements are each inclined under an angle α with respect to the horizontal plane such that, with the fluid outlet opened, all fluid entering through the fluid inlet is automatically moved towards the fluid outlet by gravity
Implementation Method 2
a cooling device through which the fluid flows, the device comprising a pipeline assembly through which the fluid flows... the cooling device serves to cool the compressor that withdraws condensable gases from a process
