The lower GWP of R32 means it has a lower impact on the environment compared to R22 and R410A. Energy efficiency: R32 has a higher energy efficiency compared to R22 and R410A, which means that air conditioning systems using R32 require less energy to operate and can result in lower electricity consumption and cost.
R32 typically cools a room faster than R410A and R22 due to its higher heat transfer efficiency. This allows for quicker cooling, making it a popular choice for air conditioning systems seeking faster cooling performance.
R290 and R32 are both gases used in air conditioning units. They're also known as refrigerants, which means they help cool down your room by turning into liquids when pumped through the system. Compared to other gases such as R12, and R22, they are safer and environment-friendly to use.
Changes to the Dangerous Goods Legislation, effective in 2021, has new categories for A2L refrigerants. R32 is a synthetic greenhouse gas. If released to the atmosphere it can contribute to climate change. R32 is a flammable refrigerant.
The two gases are also different in terms of their volumetric cooling capacity. R410A has a high VCP, which requires larger pipes. Thus, it's not as efficient as R32, whose VCP is significantly lower. Moreover, R32 has a higher pressure ratio than R410A.
Disadvantages:Different from R22 and R410A, the R32 is slightly flammable. But combustion will not occur unless three critical conditions are met, refrigerant concentration, constant oxygen, and an ignition source. In real practice, it's hard to meet all the combustion conditions.
At this mass of refrigerant charging, the cooling capacity of R32 was higher than that of R410. For four masses of refrigerant charging, the COPs of R32 were always lower than that of R410A. As a result, in terms of energy saving, it is not recommended to drop-in replacement of R410A to R32 in residential A/C.
R-454B has a lower GWP than previous refrigerants, meaning it has a much lower climate impact. Trane is phasing in the transition to R-454B in 2024, starting with the adoption of R-454B refrigerant in its residential products, beginning with the XR15 SEER2 heat pump.
As a solution, there are two alternative refrigerants used as substitute refrigerant for R22, namely R290 and R32. The R290 is widely used as working fluid in A/C system of Europe countries; meanwhile in Japan and South East countries, R32 is utilized as substitute refrigerant for R22 and R410A (Yu et al., 2010).
R-410A PHASE-DOWN TIMELINE
We will reach a 70% decrease by 2029. In 2034, we will see 80% less R-410A being produced than it is today, and the phase-down will end in 2036 with another 5% reduction.
While R32 and R410A are similar in many ways, they're incompatible with systems that aren't designed for them.
While R-12 was once the go-to choice for residential/domestic refrigeration systems, Freon™ R-134a refrigerant is now most commonly used. Its versatility allows it to work in home systems ranging from small under-the-counter refrigerators to family-sized refrigeration/freezer systems with multiple cooling compartments.
About 700 to 900 grams of gas are needed for a 1.5 ton air conditioner. But the necessary pressure varies according to the type of gas being used: R22 - 60 to 65 PSI. R32 - 110 to 120 PSI.
R410A. As opposed to R22, R410A does not damage the ozone layer and is a great alternative to R22 types of AC gas. It is a mixture of two HFC refrigerant gases – R32 and R125, with a ratio of 50/50 that is blended. The R410a gas offers outstanding performance characteristics and is chosen for many split ACs.
R-410A is not only better for the ozone layer; it also provides a better overall operation. It absorbs and releases the heat better than R-22, making your compressor run cooler so that it does not overheat.
What refrigerant will replace R-410A in 2025? For whole-home systems, Lennox has chosen 2025 Compliant Refrigerant R-454B due to its excellent performance for ducted systems and zero ozone depletion potential. For mini-splits, we selected R-32, designed to optimize efficiency and reliability in ductless systems.
The Ozone Depletion Potential is almost zero, and the Global Warming Potential is as low as 675. It doesn't harm the ozone layer like R22 gas. R32 in a refrigerant also provides better and faster cooling. It has energy efficiency properties that will help you reduce your AC bill by around 10%.
If the refrigerant used for the existing unit is other than R22, R407C and R410A, the existing refrigerant piping cannot be used. If the existing unit has another use than air conditioning, then existing refrigerant piping cannot be used.
R32 has a GWP of 675, roughly 30% lower than that of R410A. R32 systems use up to 20% less refrigerant than R410A, making them more efficient and cost less to operate. Ozone Depletion Potential of 0. Easier to recycle than R410A, as R32 is a single-component refrigerant.
In December 2022, the EPA unveiled a refrigerant ban that will go into effect between 2025 and 2026 (depending on the industry). The result? R-410A is out, shaking up the HVACR industry, which relies heavily on this refrigerant.
LG leads the way with R32 refrigerant
Now builders can take advantage of the many benefits of R32 refrigerant for their homeowners with LG solutions and technologies as a refrigerant that reliably keeps homes warm and cool.
Read on to learn why equipment prices keep going up. Have you noticed how high heating and air conditioning system prices have gotten? At the end of 2023, several leading HVAC equipment manufacturers publicly announced upcoming price increases for residential equipment in 2024.
No. R32 is not suitable as a drop-in replacement for R410A and must only be used in systems specifically designed for R32.
Only Section 608 certified technicians can purchase refrigerants intended for use with stationary refrigeration and air-conditioning equipment.
ComStar's RS-53 (R470A) is the world's only drop-in retrofit replacement for existing R410a systems.
