The capillary tool
Quickly and easily determine the right capillary
Problems of capillaries
Refrigeration circuits with integrated capillaries are typically very compact. The capillary is usually difficult for the designer to access. Furthermore, the refrigerant charge in such circuits is very small. For a variety of reasons, it is impractical to determine the capillary length iteratively by installing and removing capillaries of varying lengths and diameters.
-
Accessibility difficult
-
Risk of blockages
-
Ensuring consistent refrigerant charge after capillary replacement
-
Risk of leakage after replacing the capillary
The capillary tool as a solution
We addressed these various challenges by developing the capillary tool. This tool allows the restriction level of the capillary to be changed in several stages while the refrigeration circuit is running, without requiring any modifications. This offers several advantages for the developer:
- High efficiency
– Fast experimental results
– No material waste
- High accuracy of the design through consideration
– Internal heat exchanger
– Fill quantity and
– Routing path
- Minimal parasitic influence on the experiment
– The determined capillary flow rate and fill volumes can be used in the next development phase.
We configure the capillary tool based on the requirements of your project.
More information about the tool and its capabilities can be found in our presentation at the DKV Conference 2020.
The Solution
After a six-month testing and optimization phase, we were able to achieve our requirement of 300 W with a refrigerant charge of approximately 100 g. The charge charge is particularly crucial for future device developments using natural refrigerants.
We have achieved our stated goal of offering the autocascade approach for customer projects. We are continuously working to further develop our expertise in this area and explore its potential applications. This cycle allows us to fulfill ambitious requirements. Learning how to implement it was one of the most challenging experiences since ThermodynamX was founded.
Cool solutions for hot results.
We step in whenever thermally complex, sustainable and market-ready solutions are needed.
