Propane – an ecological solution
THE PROHIBITION OF HFCs: PROCESS COOLING IS CHANGING FAST
The F-GAS regulation (EU 517/2014) necessitates the rapid phasing out of conventional HFC (fluorinated greenhouse gases) refrigerant fluids.
Solutions for replacing HFC fluids with so-called “natural” fluids often concern CO2 and NH3 (ammonia). However, despite the progress of CO2 systems, this fluid remains heat sensitive and impractical for industrial applications. Ammonia, on the other hand, is considered a “dangerous fluid” because it can be harmful or even fatal.
A well-proven technology uses another natural gas: propane or R290.
Propane, as a refrigerant gas, is not affected by any restrictions limiting its use in industrial settings. With a GWP (Global Warming Potential) of 3 and an ODP (Ozone Depletion Potential) of zero, it appears to be an excellent alternative to HFC fluids.
A2P INDUSTRIE has always marketed environmentally-friendly and energy-efficient products, consistent with European directives and regulations. Today, A2P has naturally turned to propane. Its wide range of R290 chillers offer innovative, highly efficient technology while using an environmentally-friendly, natural refrigerant.
The propane chillers offered by A2P meet all standards and protect the installer and the operator during the refrigeration unit’s operation, including during preventive maintenance operations.
Maintenance is greatly simplified for propane chillers because R290 completely overcomes the constraints of F-gas regulations, including periodic fluid containment verification inspections.
The only maintenance tasks are those recommended by the manufacturer:
- Regular inspection and replacement of compressor oil
- Periodic calibration of the propane detector
- Cleaning of the condensers
- General evaluation (pressure measurements, etc.)
OPTIMISED ENERGY PERFORMANCE
The thermodynamic properties of propane are very similar to those of the R22 gas, an HCFC gas that is now strictly prohibited, which was once very popular because of its impressive results.
R290 is also highly energy efficient (COP of 4).
Finally, the refrigerant circuit equipped with an undercooling exchanger (see diagram below) offers three advantages:
- Stability of the oil temperature at the compressor inlet
- Elimination of all liquid slugging in the compressor
- Improved efficiency during the condensation phase
