F-Gas CO₂ EQUIVALENT CALCULATOR
One method of preventing F-gas release is through periodic leak checking of equipment containing F-gas.
The F-gas Regulation follows two tracks of action:
- Improving the prevention of leaks from equipment containing F-gases. Measures comprise:
- containment of gases and proper recovery of equipment;
- training and certification of personnel and of companies handling these gases, and
- labeling of equipment containing F-gases.
- Avoiding the use of F-gases where environmentally superior alternatives are cost-effective. From 2015 the volume of HFCs which can be placed on the EU market will be subject to quantitative limits which will be phased down over time. In addition, measures include restrictions on the marketing and use of certain products and equipment containing F-gases.
Refrigerant (F-gas or Freon) CO2 equivalent calculator - enables you to calculate the CO2 equivalent of any refrigerant, depending on the Freon number and it's respective weight.
Pursuant to Regulation (EU) 517/2014 of the European Parliament.
NEW F-gas REGULATION FROM 2015
- Limiting the total amount of the most important F-gases that can be sold in the EU from 2015 onwards and phasing them down in steps to one-fifth of 2014 sales in 2030. This will be the main driver of the move towards more climate-friendly technologies;
- Banning the use of F-gases in many new types of equipment where less harmful alternatives are widely available, such as fridges in homes or supermarkets, air conditioning and foams and aerosols;
- Preventing emissions of F-gases from existing equipment by requiring checks, proper servicing and recovery of the gases at the end of the equipment’s life.
These measures will build on and benefit from the successful phase-out of ozone-depleting substances which was achieved in the EU 10 years ahead of the internationally agreed schedule.
Thanks to the new F-gas Regulation, the EU’s F-gas emissions will be cut by two-thirds by 2030 compared with 2014 levels. Though ambitious, this reduction is achievable at relatively low cost because climate friendly alternatives are readily available for many of the products and equipment in which F-gases are commonly used today.
While the new Regulation repeals the original Regulation from 2006, the 10 implementing Regulations adopted under the original Regulation remain in force and continue to apply until new acts are adopted.
The Commission has prepared guidance documents outlining the new obligations for users and technicians of refrigeration, air conditioning and heatpumps under the new regulation (EU No 517/2014).
As the thresholds for obligations in the new Regulation are given in CO2 equivalents, a calculation tool is being made available to translate tonnes CO2 equivalents into metric tonnes.
HFC phase-down – the “2018 big cut”
The quantity of HFCs that can be placed on the EU market will be cut in a series of steps as illustrated in Figure 1. By 2030, only 20% of the quantity of HFCs that were sold in 2015 will be available. The HFC phase-down is the most crucial aspect of the F-Gas Regulation and will have a major influence on use of refrigerants in all end use markets including food and drink manufacturing. The first really big cut in HFC supply comes in 2018 – when there will be a cut of around 40%. It is likely that HFC refrigerant prices will rise sharply in 2017 / 2018 as there is potential for a significant refrigerant shortage.
service ban that affects existing refrigeration equipment
In January 2020 there will be a ban on using HFCs to service refrigeration equipment that uses a refrigerant with a GWP above 2500. This mainly affects R-404A equipment, but is also relevant to plants using refrigerants such as R-507, R-434A and R-422D. There is an exemption for very small equipment (e.g. containing less than 10 kg of R-404A) and for plants that cool a product to below -50oC. If you own equipment that is affected by the service ban you need to make plans based on one of three options:
a) Licensed engineer can retrofit the existing plant with a lower GWP refrigerant (it must have a GWP below 2500). For example, R-404A systems can be retrofitted with R-407F, R-448A or R-449A. This usually requires very few modifications to the existing plant and there is good evidence that energy efficiency will improve after a well-executed refrigerant retrofit.
b) Technicians can service the existing plant using reclaimed refrigerant. However, there is no guarantee that reclaimed refrigerant will be available.
c) A system can be replaced with a new system that uses a lower GWP refrigerant.
It is important to recognise that the big phase-down step in 2018 comes 2 years before the service ban. High GWP refrigerants such as R-404A are likely to become very expensive by 2018 – retrofitting or replacing such equipment before 2018 is worth strong consideration.
refrigerant choices for new equipment
The main driver to use low GWP refrigerants in new equipment is the HFC phase-down. Most refrigeration equipment used in food and drink manufacturing has a life of well over 25 years. Buying plant with low GWP refrigerants helps “future-proof” your new systems.
In addition to the pressure created by the HFC phase-down, the F-Gas Regulation bans the use of HFC refrigerants with a GWP above 2500 in all new stationary refrigeration equipment from January 2020. However, the timing of this ban hides an “implicit ban” that is already in place. It makes no sense to purchase new industrial refrigeration equipment with a GWP above 2500 in 2016 – as such equipment will need to comply with the service ban in 2020!
In the food and drink manufacturing sector there are many options for using ultra-low GWP refrigerants in new equipment.
Very high GWP refrigerants such as R-404A should be avoided with immediate effect and you should seriously question anyone giving you advice to use “medium-high” GWP HFCs such as R-134a or R-410A. Ammonia has been widely used in the industry for many years and is an excellent option, especially for large refrigeration equipment. For liquid chillers (e.g. for cooling a glycol secondary refrigerant) there are good alternatives with low GWP e.g. the HFO refrigerant R-1234ze (GWP = 7) is becoming widely available as an alternative to R-134a.
Ammonia is well suited to large liquid chillers. CO2 is already widely used in supermarket refrigeration systems and is now available for a range of industrial refrigeration applications.
A number of new refrigerant blends are being introduced by refrigerant manufacturers – around 20 new blends have been launched during the last 3 years.
Most of these new refrigerants are blends of HFOs and HFCs. They have been designed to mimic the properties of the high GWP refrigerants that they are replacing. For example, some blends have properties similar to R-404A. Two of these (R-448A and R-449A) have the advantage of being non-flammable but the disadvantage of still having a fairly high GWP (around 1400).
Some more recently introduced blends (such as R-454A and R-455A) have much lower GWPs (239 and 148 respectively) but have the disadvantage that they are very slightly flammable. Lower flammability refrigerants are referred to as category 2L in the latest refrigeration safety codes. They are very difficult to ignite and can be used safely in many applications if the correct design rules are applied. It is worth noting that ammonia is also a “2L” refrigerant and has almost never been ignited following a refrigerant leak.
When purchasing new equipment, you should always give adequate consideration to energy efficiency. Over the life of the plant the use of energy is the most significant contributor to greenhouse gas (GHG) emissions. The F-Gas Regulation only relates to avoiding the GHG emissions from the refrigerant itself.
