32 cards. Read the term and the definition here. The deck at the top of this page is optional.
- F-Gas Regulation
- EU Regulation 517/2014 that controls fluorinated greenhouse gases, including HFCs, PFCs, and SF6, through phase-down quotas, leak checks, and certification requirements.
- ODS Regulation
- EU Regulation 1005/2009 that phases out ozone-depleting substances such as CFCs, HCFCs, halons, and methyl bromide, covering production, use, and trade.
- CO2 equivalent
- The mass of a greenhouse gas multiplied by its Global Warming Potential, used to compare emissions and determine leak check thresholds under F-Gas rules.
- Leak check frequency
- Required intervals based on CO2e charge: every 12 months for 5–50 tCO2e, every 6 months for 50–500 tCO2e, and every 3 months above 500 tCO2e, doubled if a leak detection system is installed.
- Record keeping period
- Operators must keep records of refrigerant handling, leak checks, and repairs for at least 5 years under the F-Gas Regulation.
- HFC servicing ban
- Since 1 January 2020, servicing equipment with HFCs of GWP ≥ 2500 is banned unless using reclaimed refrigerant or for export, under the F-Gas Regulation.
- Category III certification
- Certification required for personnel servicing equipment containing less than 3 kg of F-Gas, or less than 5 tCO2e if hermetic, under the F-Gas Regulation.
- Placing on the market
- The first supply or making available of F-Gases or products containing them in the EU, subject to phase-down quotas and labelling requirements.
- Ozone Depletion Potential
- A relative measure of a substance's ability to destroy stratospheric ozone, with CFC-11 assigned a value of 1; HCFC-22 has an ODP of 0.055.
- Global Warming Potential
- A relative measure of a greenhouse gas's warming effect over 100 years compared to CO2, e.g., R-404A has GWP 3922 and R-410A has GWP 2088.
- TEWI
- Total Equivalent Warming Impact, which combines direct refrigerant emissions and indirect emissions from energy use over a system's lifetime.
- Atmospheric lifetime
- The average time a gas remains in the atmosphere; CFC-12 lasts about 100 years, while HFC-134a lasts about 14 years, affecting overall environmental impact.
- ODS environmental harm
- Ozone-depleting substances break down in the stratosphere and release chlorine or bromine, which destroy ozone molecules and increase UV radiation reaching Earth.
- HFC environmental impact
- HFCs do not deplete the ozone layer but are potent greenhouse gases with high GWP values, contributing to climate change when emitted.
- Direct emissions
- Refrigerant released to the atmosphere from leaks, servicing, or disposal, contributing directly to global warming based on the refrigerant's GWP.
- Indirect emissions
- CO2 emissions from the energy used to power refrigeration equipment over its lifetime, forming part of TEWI.
- Recovery cylinder filling limit
- Recovery cylinders must never be filled above 80% of their capacity by volume, and filling must be monitored with a calibrated scale.
- Recovery efficiency
- The percentage of refrigerant that must be recovered during servicing: at least 90% for systems with less than 3 kg charge, and at least 95% for larger systems.
- Refrigerant identification
- Before recovery, the refrigerant type must be identified to avoid mixing; mixing different refrigerants prevents reclamation and may make the mixture hazardous.
- Reclaimed refrigerant
- Refrigerant that has been reprocessed to meet specified purity standards, such as AHRI 700, and can be reused in equipment.
- Venting prohibition
- It is illegal to deliberately release F-Gases or ODS to the atmosphere; recovery is mandatory to prevent environmental harm.
- Flammable refrigerant recovery
- Recovery of flammable refrigerants like R-290 requires equipment rated for flammables and adherence to safety procedures to prevent ignition.
- Recovery record
- Documentation of the quantity of refrigerant recovered and its destination (recycled, reclaimed, or destroyed) is required for compliance.
- Leak detection methods
- Common methods include visual inspection, soap bubbles, electronic leak detectors calibrated for the refrigerant, and UV dye where permitted.
- Leak repair deadline
- After a leak is detected, repair must be completed within 14 days; if not feasible, a documented plan and increased leak checks are required.
- Follow-up leak check
- A leak check must be performed within one month after a repair to confirm the leak is fixed.
- Record content
- Records must include date, refrigerant type, quantity added, leak check results, repairs, and technician identification.
- Personal protective equipment
- PPE such as gloves and goggles must be worn when handling refrigerants; ensure ventilation to avoid asphyxiation from vapours.
- Flammable refrigerant safety
- When working with flammable refrigerants, eliminate ignition sources, use gas detectors, and follow ATEX requirements.
- Cylinder storage
- Refrigerant cylinders must be stored upright, secured, away from heat, and within specified temperature limits.
- Leak detection system check
- Leak detection systems must be checked annually, and their alarm function must be tested to ensure proper operation.
- Electronic leak detector calibration
- Electronic leak detectors must be calibrated for the specific refrigerant type and have appropriate sensitivity, typically 5 g/year.
