Types of Refrigerants: What You Need to Know Refrigerants are essential in cooling systems like air conditioners and refrigerators. Here's a quick guide to the main types: 1. CFCs (Chlorofluorocarbons): - Example: R12 - Phased out due to high ozone depletion. 2. HCFCs (Hydrochlorofluorocarbons): - Example: R22 - Less harmful to the ozone but still being phased out. 3. HFCs (Hydrofluorocarbons): - Example: R134a, R410A - No ozone harm, but high global warming potential (GWP). 4. Natural Refrigerants: - Examples: Ammonia (R717), CO₂ (R744), Propane (R290) - Environmentally friendly but can have other risks like flammability or toxicity. 5. HFOs (Hydrofluoroolefins): - Example: R1234yf - Low GWP and no ozone impact—more eco-friendly. 6. Refrigerant Blends: - Examples: R407C, R404A - Mixtures designed for specific cooling needs. Choosing the right refrigerant means balancing efficiency with environmental impact. As we move towards more sustainable options, natural refrigerants and HFOs are gaining popularity.

The new Unichiller CO2 is another milestone in environmentally friendly refrigeration technology at Huber. The new circulation cooler works with CO2 as a refrigerant. CO2 or carbon dioxide (also known as R744) is a natural component of the air and has been used in refrigeration technology since the 19th century. CO2 is a colorless gas that liquefies under pressure. It has no ozone depletion potential (ODP = 0) and, with a GWP = 1, has a negligible global warming potential.   For example, if 1 kg of CO2 escapes into the atmosphere through a leak in the refrigeration circuit, this is 3780 times less harmful than the common refrigerant R404A. In addition, CO2 is a so-called natural refrigerant that occurs in very large quantities in nature, meaning it does not have to be produced with great energy expenditure. In addition, CO2 has other advantages as a refrigerant; it is non-flammable, non-toxic and chemically inactive.   The new Unichiller CO2 is therefore a 100% environmentally friendly alternative to cooling devices with conventional synthetic refrigerants. The Unichiller CO2 offers pioneering refrigeration technology and Huber's proven circulation cooler technology. Advantages:   Proven Unichiller technology Environmentally friendly refrigeration technology Ozone depletion potential equal to zero (ODP = 0) Global warming potential negligible (GWP = 1) Very good energy efficiency Refrigerant is non-flammable and non-toxic High operational reliability Whisper-quiet operation (only 60 dB) Future-proof investment (not affected by the F-gas regulation) Intermass Fischer-Asia Pte Ltd Benjamin Chan Razis Halim James Chong Tiong Wai #ThermalTechnik

Propane, first used as a refrigerant over a century ago, has made a comeback as the hottest new refrigerant candidate. Celebrated for its safety for the ozone layer, negligible global warming impact, and excellent thermodynamic properties, propane is making waves in the industry. A Journey Through Refrigerants: In the early days of air conditioning and refrigeration, naturally occurring refrigerants like propane, ammonia, and sulfur dioxide were used. With the advent of non-flammable and non-toxic synthetic refrigerants in the 1920s, a shift occurred. However, these synthetic refrigerants, including CFCs, HCFCs, and HFCs, were later found to harm the ozone layer and contribute significantly to global warming. Even the latest generation of synthetic refrigerants, HFOs, have raised health concerns. Return to Natural Solutions: Propane (R-290), a natural hydrocarbon, is already widely used in applications from barbecues to refrigeration. It has excellent thermodynamic properties and no adverse effects on the ozone layer or global warming. Unlike ammonia, it is non-toxic. Future-Proof and Sustainable: Propane is a future-proof solution, avoiding the tightening restrictions on synthetic refrigerants. As a naturally occurring compound, propane is not subject to the same regulations. This makes it a sustainable and long-term choice for refrigeration needs. Swegon is leading the charge with innovative propane-based technologies and comprehensive training programs to support industry transition. Why This Matters in NZ: New Zealand’s strong environmental commitment makes it perfect for adopting propane-based solutions.

Due to the rising cost of R134a refrigerant, unscrupulous racketeers are introducing counterfeit refrigerants, supplied in illegal containers, to take advantage of unsuspecting workshops across Europe, according to DENSO Aftermarket Europe's Fatiha Laauich: "The reason that prices are rising is linked to changes in European legislation that began in 2014, when the European Commission decided to control emissions from fluorinated greenhouse gases (F-gases), including hydrofluorocarbons (HFCs), and the European Union (EU) adopted two legislative acts: the F-gas Regulation and the Mobile Air Conditioning (MAC) Directive. The aim of both acts is to enforce the use of gases with a global warming potential (GWP) lower than 150. "In addition, in 2015, the EU introduced the Phase Down mechanism to gradually reduce the consumption of high GWP refrigerants, like R134a, which until recently was the most common air conditioning (AC) refrigerant used by VMs, so that in 2030, only one fifth of the 2014 total sales volume of high GWP HFCs should be available on the market." #PMF #DENSO #automotiveaftermarket #motorfactor #r134a #EU #legislation
