HFCs

Draft F-Gas reforms pose huge challenge for EU heat pump ambitions


This week’s F-Gas Concern Time looked at how stricter ambitions to stage down HFC refrigerant use could influence the industry’s skill to install warmth pumps at an enhanced amount

Current proposals to introduce sticker F-Gas laws quotas on the amount and form of refrigerant permitted on the European industry dangers probably undermining warmth decarbonisation, an field debate has heard.

The 2022 F-Gas Dilemma Time, which was hosted on the web by H&V News’ sister title RAC Magazine on Could 24, reported first reform options would put sizeable provide pressures on HFC refrigerant offered for current techniques. These pressures could also develop important worries for encouraging warmth pump adoption in Europe that will also call for a reliable offer of refrigerant in line with F-Fuel limitations.

The most up-to-date Concern Time read from specialists about present-day progress underneath the proposals to extra to reduce GWP refrigerant for uses such as cooling and heating.

The party, sponsored this 12 months by Chemours, has been hosted by the magazine for over ten a long time to contemplate the performance of the flagship European regulation and how it is impacting the RACHP field.

H&V Information editor Andrew Gaved mentioned the most up-to-date Question Time was being held as the European Fee is trying to find opinions on controversial revisions to its quota process and timetable.  These amendments – if handed in their latest form – would imply considerably fewer HFC is available from the finish of the decade for the RACHP.  This would travel a need to have for bigger use of refrigerants with one of a kind dealing with necessities and methods and installers in a position to properly manage them

At existing, the present regulation imposed into each British isles and EU law demands by 2030 that the availability of HFCs on the current market is cut to 79 per cent of 2015 levels.  The most up-to-date European Fee proposals would see this amount of money reduce to 95 for each cent over the same timeline if introduced.

Consultant Ray Gluckman explained to the Concern Time viewers that the regulation reforms would complicate ambitions in each Europe and the United kingdom to decarbonise room heating.

He stated, “One of the most essential applications, and a really fascinating instrument as significantly as our sector is involved, is that we are heading to use heat pumps to do that.  But we have to install all those people heat pumps and that will take a large amount of new gasoline likely into the equipment.”

The scale of this challenge has been further amplified by the publication this month by the European Commission of the REPowerEU Program in reaction to problems about the amounts of fossil fuel fuel provided to Europe from Russia right after its invasion of Ukraine, Mr Gluckman included.

The system commits to ramp up warmth pump use across the EU by 2030 to minimize demand from customers for fossil fuel heat in marketplaces such as Germany.

The Environmental Investigation Company (EIA) mentioned prior to this year’s Issue Time that the European Fee proposals for revising F-Fuel legislation ought to go additional and thrust for a whole ban on any tools these types of as heat pumps built to use any HFCs.

Clare Perry, climate campaigns chief for the EIA, argued at the time that ambitions for expanding warmth pump installations should really not guide to an boost in HFC use when decrease GWP alternatives have been readily available.

For the duration of a panel discussion at this year’s F-Fuel Problem Time, gurus have been asked regardless of whether they were fear mongering about the impacts of the proposals in a similar method to worries lifted about the introduction of the initial F-Fuel commitments a 10 years ago.  This was notably the circumstance with regards to ambitions to move to even reduced GWP fuel items that will introduce greater ranges of flammability, stress or toxicity in their managing specifications.

Mr Gluckman reported in response that the field did want to go to units that properly assistance reduce GWP systems, but the industry also experienced to shift to greater flammability products such as propane refrigerant with warning.

He claimed, “The time presented to transfer an field, for instance, to propane, it seems completely wrong.”

Other members of the panel said that there had been important coaching issues, along with study and improvement and enough regulation wanted to make certain units can be installed and maintained to operate at an successful level with decreased GWP refrigerant at a mass scale.

Mark Woods, controlling director of facilities administration professional Arcus FM, said in the course of the discussion that upskilling was as similarly essential as maker R&D to make certain sector was prepared to go in higher figures in the direction of nevertheless another technology of refrigerants.

He explained, “The significant enterprises, the big contractors, those that are affiliated with trade associations will be professional.  But we have a enormous tail in the sector that even now has not caught up with the past regulation adjustments.”

A failure to the right way introduce a approach of making sure competence for handling reduced GWP refrigerants these as hydrocarbons risked undermining their safe and sound and productive use, the panel extra.

A.G. Coombs issues advice on commercial HVAC refrigerants


A.G. Coombs has developed an update on its information about refrigerant use for industrial HVAC units.

“As the planet grapples with rising temperatures brought on by the emission of greenhouse gases, refrigerants are underneath renewed scrutiny,” A.G. Coombs states. “Common refrigerants are categorized as greenhouse gases, which can be hundreds or even a thousand moments even worse from a global warming possible (GWP) compared to the equal volume of normal refrigerants this sort of as carbon dioxide (CO2).”

The Advisory Take note is specific, furnishing details on the HFC stage-down and Montreal Protocol, the point out of the existing refrigerant sector, HFC possibilities, refrigerant traits, and an evaluation of what the phase-down signifies for industrial HVAC methods.

Considering that the period-out of chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs), the most prevalent form of refrigerant obtainable in the market place these days are hydrofluorocarbons (HFCs).

“The big issue with HFCs occur from their world wide warming prospective,” the be aware advises. “GWP is a bodily assets of greenhouse gases, which indicates the propensity of the gas to entice atmospheric warmth.”

The observe goes on to clarify the HFC section-down is a gradual reduction in the maximum quantity of HFCs permitted to be imported into Australia.

“The composition of the Australian governing administration HFC phase-down is geared in the direction of restricting the importation of HFC gases, with a see of encouraging marketplace forces to identify the most effective resolution,” the observe says. “As these kinds of, it is helpful to notice the industry to see what adjustments, developments and innovations are taking location.”

So, what does this imply for business HVAC units?

“With the stage-down of HFC refrigerants, there will be diminished source, and this is probable to consequence in raising price tag of the fuel over time,” states A.G. Coombs. “This has been observed with an growing price tag of R134a more than the previous five decades.”

The note advises maintaining an exact asset timetable of all incorporating HFC refrigerants, speaking with mechanical upkeep companies to recognize any HFC plant working inefficiently, making ready a refrigerant administration strategy, examining chiller plant alternative techniques, and thought of units that can offer both of those cooling and heating at the exact same time to leverage charge efficiencies.

“It must be observed that the Kigali agreement is a phase-down and not a stage-out, meaning there are no HFC production bans as there had been with hydrochlorofluorocarbons (HCFCs) these types of as R22,” the observe suggests. “However, it is nonetheless critical to take into consideration the choice of the refrigerants in any new and alternative plant.”

A.G. Coombs has developed an update on its suggestions about refrigerant use for commercial HVAC devices.

“As the environment grapples with climbing temperatures prompted by the emission of greenhouse gases, refrigerants are less than renewed scrutiny,” A.G. Coombs claims. “Common refrigerants are labeled as greenhouse gases, which can be hundreds or even a thousand occasions worse from a worldwide warming likely (GWP) vs . the equal quantity of organic refrigerants such as carbon dioxide (CO2).”

The Advisory Be aware is in depth, providing information on the HFC section-down and Montreal Protocol, the condition of the present-day refrigerant marketplace, HFC options, refrigerant traits, and an evaluation of what the section-down usually means for industrial HVAC programs.

Considering the fact that the phase-out of chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs), the most common type of refrigerant accessible in the market today are hydrofluorocarbons (HFCs).

“The important trouble with HFCs crop up from their worldwide warming opportunity,” the be aware advises. “GWP is a physical residence of greenhouse gases, which signifies the propensity of the fuel to entice atmospheric warmth.”

The note goes on to reveal the HFC section-down is a gradual reduction in the optimum volume of HFCs permitted to be imported into Australia.

“The framework of the Australian authorities HFC stage-down is geared towards restricting the importation of HFC gases, with a watch of encouraging marketplace forces to ascertain the best remedy,” the be aware says. “As this sort of, it is helpful to notice the sector to see what variations, developments and innovations are using place.”

So, what does this suggest for commercial HVAC techniques?

“With the section-down of HFC refrigerants, there will be lessened provide, and this is most likely to consequence in growing price tag of the gas around time,” states A.G. Coombs. “This has been observed with an raising cost of R134a more than the previous 5 a long time.”

The be aware advises maintaining an exact asset schedule of all incorporating HFC refrigerants, talking with mechanical servicing providers to detect any HFC plant functioning inefficiently, getting ready a refrigerant administration approach, reviewing chiller plant substitute approaches, and thing to consider of systems that can provide both of those cooling and heating at the exact time to leverage price efficiencies.

“It must be famous that the Kigali settlement is a period-down and not a period-out, which means there are no HFC production bans as there had been with hydrochlorofluorocarbons (HCFCs) these as R22,” the observe states. “However, it is however significant to take into consideration the range of the refrigerants in any new and alternative plant.”
