THE UE F-GAS REGULATION
THE RIGHT GAS FOR THE RIGHT APPLICATION
NAYCH is manufacturing air conditioners with 2 types of gas as part of the evolution of European Regulations n°517/2014 on Fluorinated Greenhouse Gases (F-Gases) aimed at reducing the carbon footprint of HVAC equipment. R32 gas, which delivers good energy performance and R513A gas for the world’s hottest regions.
R32 : ODP=0 / GWP = 675 / FIRE CLASS A2L / GLIDE = 0°K
R513A : ODP=0 / GWP = 631 / FIRE CLASS A1 / GLIDE = 0°K
F-GAS R513A
R513A is a non-ozone depleting, low global warming potential (GWP) refrigerant blend used primarily as a replacement for higher GWP refrigerants such as R134a and R404A in various refrigeration and air conditioning applications. It is a ternary blend composed of hydrofluoroolefin (HFO) and hydrofluorocarbon (HFC) components.
Chemical composition:
- HFO (Hydrofluoroolefin): R1234yf (2,3,3,3-Tetrafluoropropene)
- HFC (Hydrofluorocarbon): R134a (1,1,1,2-Tetrafluoroethane)
R513A has favorable properties in terms of energy efficiency and environmental impact. It has a significantly lower GWP compared to traditional HFC refrigerants, making it compliant with regulations aimed at reducing greenhouse gas emissions. Additionally, R513A exhibits good thermal properties, making it suitable for various cooling applications across different temperature ranges.
Key technical specifications of R513A typically include:
- Chemical formula: CH2=CFCF3 (R1234yf) + CH2FCF3 (R134a)
- Boiling point: -42.7°C (-44.9°F)
- Critical temperature: 112.5°C (234.5°F)
- Global Warming Potential (GWP): Around 631 (over a 100-year period, compared to CO2)
- Ozone Depletion Potential (ODP): Zero
R513A is considered a promising refrigerant choice for achieving environmental sustainability goals while maintaining reliable cooling performance. However, as with any refrigerant, proper handling, storage, and disposal practices should be followed to minimize environmental impact and ensure safety.
F-GAS R32
R32, also known as difluoromethane, is a hydrofluorocarbon (HFC) refrigerant with the chemical formula CH2F2. It is a colorless gas at room temperature and has a faint sweet odor. R32 is widely used in air conditioning and refrigeration systems as a replacement for chlorofluorocarbon (CFC) and hydrochlorofluorocarbon (HCFC) refrigerants due to its lower global warming potential (GWP).
Properties of R32:
- Chemical Formula: CH2F2
- Molecular Weight: 52.02 g/mol
- Boiling Point: -51.7°C (-61.1°F)
- Critical Temperature: 78.1°C (172.6°F)
- Critical Pressure: 5.8 MPa (841 psi)
- GWP (Global Warming Potential): 675 (over a 20-year period)
Applications: R32 is primarily used as a refrigerant in:
- Residential air conditioning systems
- Commercial air conditioning systems
- Heat pumps
- Some small-scale refrigeration systems
Advantages of R32:
- Lower GWP compared to older refrigerants like R410A, making it environmentally friendly
- Higher energy efficiency in many applications compared to other refrigerants
- Improved heat transfer properties, leading to better system performance
Safety Considerations: While R32 is generally considered safe for use in air conditioning and refrigeration systems, it is important to handle it with care due to its flammability. Proper storage, transportation, and handling procedures must be followed to mitigate any risks.
Environmental Impact: R32 has a relatively low GWP compared to many other refrigerants, which contributes to reducing the overall environmental impact of air conditioning and refrigeration systems. However, as with any refrigerant, proper handling and disposal practices are essential to prevent environmental harm.
Overall, R32 is a promising refrigerant choice for various applications, offering a balance of environmental sustainability, energy efficiency, and performance.
