2024年11月18日 · This fact sheet provides current information on low global warming potential (GWP) alternative refrigerants to high-GWP hydrofluorocarbons (HFCs) for use in commercial refrigeration equipment.

Traditional refrigerants, such as hydrofluorocarbons (HFCs), have high GWP values, meaning they have a significant impact on climate change. Low-GWP refrigerants, on the other hand, have much lower GWP values, making them a more environmentally friendly choice. What is …

This fact sheet provides current information on low global warming potential (GWP)1 alternative refrigerants to high-GWP hydrofluorocarbons (HFCs) for use in residential and commercial air conditioning (AC) equipment, including chillers.

HFCs are powerful greenhouse gases (GHGs) with GWPs hundreds to thousands of times more potent per pound than carbon dioxide (CO2); however, more low-GWP alternatives are becoming available.

Low-GWP refrigerants work by absorbing heat from one area (like the inside of your home) and releasing it elsewhere (usually outdoors). Their chemical compositions are designed to achieve this process while significantly reducing greenhouse gas emissions.

2025年1月6日 · Some common examples of low GWP refrigerants include hydrofluoroolefins (HFOs) like HFO-1234yf and HFO-1234ze, which have GWP ratings significantly lower than traditional refrigerants such as R-134a. Natural refrigerants like carbon dioxide (R-744), ammonia (R-717), and hydrocarbons (such as propane, R-290) are also considered low-GWP options ...

Environmental regulations and sustainability initiatives are driving the commercial refrigeration industry toward low-global warming potential (GWP) refrigerant alternatives. Copeland's new webinar series addresses key challenges, considerations and landmarks on the road ahead.

2024年10月2日 · A low-GWP refrigerant offers an optimized balance between performance, safety, and sustainability as it can enhance energy efficiency and reduce the carbon footprint of a system. Keep reading to explore in detail about these refrigerants and why they are the future of cooling systems .

5 天之前 · As of January 1, 2025, the EPA’s Technology Transitions Program has started to phase in prohibitions on the manufacturing of certain categories of HVAC equipment that use refrigerants with a global warming potential (GWP) over 700. As a result, contractors can expect to see an influx of new equipment using low-GWP refrigerants such as R-454B.

The transition to low Global Warming Potential (GWP) refrigerants represents a positive step for the environment, as it significantly reduces the impact of harmful greenhouse gases. What’s Changing?
