European regulation CE 517/2014 makes the replacement of fluorinated gases (F-gases) compulsory, such as R410A, for environmental reasons, although it also grants a transition period from 2017 to 2030.

Must we wait?……… It appears not most manufacturers are jumping the gun and are now presenting new generation of air conditioners that employ the R32 refrigerant.

R32 refrigerant systems are rapidly coming onto the market with major manufacturers such as Daikin, Mitsubishi, Hitachi, Pansonic and many others bringing out new brochures with R32 refrigerant systems now readily available in a wide range of types of systems, such as wall, cassette, floor and ducted options New R32 ranges claiming higher seasonal energy efficiency, together with half GWP of predecessor refrigerant gases and less quantity of refrigerant required in R32 systems, compared to alternative refrigerant operating systems.

Daikin UK has launched its new air conditioning range, named Bluevolution, using R32 refrigerant. Encompassing Daikin Split and Sky Air systems, the R32 Bluevolution range offers a future proof, affordable, air conditioning solution, the firm says, along with being quick and easy to install with reduced leak check requirements.

Following the initial launch of the Bluevolution range in Europe, for traditional split units, the Bluevolution range has now expanded to include the Daikin Emura and Sky Air products. The R32 range now also includes the Seasonal Smart High COP Roundflow Cassette and new iTab Controller.

The new range provides the highest Seasonal Energy Efficiency Ratio (SEER) and Seasonal Coefficient of Performance (SCOP) ratings, offering improved energy efficiency and reduced environmental impact.

Daikin UK launched the first commercial R32 range within the UK market. As the F-Gas phase-out continues, it is important installers and customers make the move to lower GWP refrigerant-based systems. There is very little difference to the R410A installation process, installation with R32 gas is simple and straightforward, and provides only benefits for the end user.

Offering the ultimate in energy efficiency and control, the new Bluevolution range delivers a future proof investment throughout the F-gas phase out. Alongside the efficient R32 refrigerant, additional new system features, such as a power saving mode, ensure low running costs over the course of the systems’ lifetime.”

Panasonic introduced the R32, which has zero impact on the ozone layer and lower impact on global warming than previous refrigerants, Panasonic say, A ‘small’ change that changes everything, not everyone is ready for change. Indeed, there are some who resist the future. But at Panasonic we will keep believing in technologies that improve people’s lives.
Which is why we are now presenting a new generation of air conditioners with R32, an innovative refrigerant in all ways imaginable: it is easy to install, environmentally friendly and saves energy. The result? Greater wellbeing for people and for the planet. Because there will always be people who resist change. But we say: Goodbye yesterday. Hello R32.

Mitsubishi Electric Time for R32 to be at the heart of your project

It’s time to enjoy energy savings and great new product features.

It’s time for your air conditioning to help meet EU carbon emissions targets.

It’s time to put R32 refrigerant at the heart of your conversations and plans moving forwards, with the market leading range of R32 products from Mitsubishi Electric.

Why R32?

The 2014 F–Gas Regulations will bring about significant changes to the air conditioning industry, affecting end users, facilities managers, specifiers and installers alike.

R32: The Benefits:

  • Low GWP of 675
  • High efficiency refrigerant
  • F–Gas phasedown compliant
  • Less refrigerant volume requirement compared to R410A
  • Affordable & readily available
  • A single component refrigerant
  • Easy to handle, reuse and recycle
  • Used in our newest,
    state–of–the–art products

This landmark ruling has one key objective: to reduce F–Gas emissions by 79% between 2015 and 2030, by cutting the availability of hydrofluorocarbons (HFCs) with a high Global Warming Potential (GWP). It’s now up to everyone to make a real ‘green commitment’ – from manufacturers to installers, and managers to owners of air conditioning and refrigeration equipment.

It’s time to look at alternatives, like R32. Already making up 50% of the existing R410A refrigerant found in many current air conditioning systems, R32 has a GWP of 675 (one third that of R410A), is highly energy efficient and is easy to recycle. Plus, the volumetric capacity of R32 is around 20% higher than that of R410A, which means system refrigerant volumes are lower.

Hitachi Launch R32 RAC first series of Hitachi introduced in Japan

Hitachi launched its first R32 air conditioning units into the European market in 2017. The company introduced its first series R32-RAC to the market in Japan in 2013. In Japan, the complete range of RAC products should be converted to R32 will be offered as an entry-level model at the beginning of 2017.

The new RAC series with R32 will set itself apart from the current performance series with a new, elegant design.

Hitachi Air Conditioning Europe SAS said: “With the introduction of the new R32-RAC series. We will continue the attractive price-performance ration in this segment. This new refrigerant enables us to increase efficiency by a whole level, to simultaneously reduce the GWP and therefore to act in a much more environmentally friendly manner.”

Unlike R410A, R32 is a mixture of R125 and R32, significant advantages which do not effect the environment. Currently it is the only refrigerant which has almost the same temperature and pressure range as R410A. Furthermore, it is about 10 per cent more efficient that R410A, resulting in higher COP and EER. The pipeline cross-section, the compressor power and the filling capacity can be reduced by up to 30 percent in comparison with R410A.

Other Key points of New Refrigerant

  • New Refrigerant has a GWP of 675 compared with R410A’s GWP of 2,088
  • It can be more energy efficient than R410A • Smaller charges result in heat exchangers and other components being more compact
  • It is rated as A2L – there is a low risk of accidents due to toxicity (A), and low risk of flammability (2L)
  • As a single component refrigerant, R32 is easier to reuse and recycle • The boiling temperature of R32 is similar to R410A, slightly higher than R22 •

It is easy to handle because it doesn’t fractionate The move towards new refrigerant  is part of an overall strategy to reduce the impact of refrigerants on the environment. In 2020 refrigerants such as R404A and R507, with a GWP higher than 2500, will be banned for use in stationery units and will have to be converted to R407A. By 2025 refrigerants with a GWP greater than 750 will be banned for use in splits air conditioning units, and in 2030 use of R410A, R134A and R407C will be heavily restricted.

Chillaire Limited are continuing to advise customers to actively start looking at R32 refrigerant systems as R410a refrigerant gas prices sky rocket, they have already trebled in price over the past 12 months and stock levels are diminishing by the day, as suppliers are restricted to quota stock levels by refrigerant manufacturers and government legislation.
