Considerations in mitigating refrigerant leaks
The most significant consideration in refrigeration leak prevention will be the equipment manufacturer and the company that's designing and installing the equipment.
In addition to choosing the right manufacturer and refrigeration system designer, there are three other main factors we advise to minimise refrigerant leakages and their effects.
1. Natural alternatives
Viessmann Refrigeration is committed to ecological sustainability to ensure a good life for tomorrow’s generations. That’s why we recommend using refrigerants that are proven to have minimal harmful effects on our planet and the environment.
Viessmann Refrigeration explores ways to utilise these natural refrigerants — and even more with every new installation.
At Viessmann Refrigeration, HVAC and refrigeration is just the beginning. We focus on fully integrated solutions, progressing with a holistic and tailored approach for each unique customer by utilising the power and expertise of our experienced experts.
With a varying range of food retail shops, we recommend holistic solutions starting from secondary refrigerant systems in combination with R290 heat pumps and chillers up to transcritical CO2 booster systems while shifting away from synthetic refrigerants and fossil fuels.
We are strongly convinced that this is the ultimate way to go forward to achieve individual and global sustainability targets set by simultaneously keeping operational costs down.
2. System and component design
When designing a new refrigeration system, the manufacturer and designer must focus on what will maximise the hermitisation concerning all joints and fixtures.
With any system, only hermetically sealed components and brazed joints should be utilised, when possible.
While there have been attempts and innovative breakthroughs around new types of pipework, copper is typically the best and most ideal solution.
“In most environments, copper can withstand for many years in various environments and impacts,” says Christoph. “However, when we know there’s a significant chance of impact due to vibration on parts of our systems, we’ll typically also utilise stainless steel solutions and strong connections that are more resistant to those forces.”
3. Reduce the overall charge of your systems.
With any refrigeration system, we recommend having a limited amount of refrigerant available at any given time.
Reducing the refrigerant charge can limit and sometimes even fully contain and prevent refrigerant from penetrating the air, whether a small leak or something more catastrophic to the system.
Consider a pipe break due to outside impact, where the refrigerant is immediately released into the air.
To improve the installation quality, Viessmann Refrigeration Solutions is putting a tremendous amount of focus on insourcing field erection work into the factory, helping to ensure best-in-class quality while supporting field installers with pipe work under the most convenient conditions.
