While making the switch to R32 refrigerant may not seem urgent today, many companies are turning to the products with a low global warming potential (GWP). R32 is an excellent alternative to the popular R410A. In fact many leading manufacturers are already producing equipment which works with R32 only.
By 2025, the refrigerants with a large GWP (over 750) will be banned together with the systems using it. R410A has a GWP of over 2,000. Meanwhile, R32 has a low GWP of 675. It’s obvious which one is the refrigerant of the future.
What Is The R32 Air Conditioner?
The R32 air conditioner is a HFC refrigerant, used as a replacement for the R410A in low temperature refrigeration and air conditioning applications. This refrigerant is a preferred replacement for R410 in new equipment.
How To Handle The Pressure
The operating pressures of a gas are important for manufacturers as well as users. Would the equipment need new hoses and gauges to operate with R32? The new refrigerant pressures are only slightly higher than for R410A.
The working pressure of the two refrigerants is comparable, making it easy to make the transfer from one to another. New equipment for R32 can be based on the R410A platform.
R32’s pressure ratio is a little higher than R410A. The isentropic exponent affects the pressure ratio and the discharge temperature.
The working (operating) pressure of R32 is about 12 – 26 Bar (174-377 Psi). It should be noted that while the operating pressure of R32 and R410A is similar, the former has a better ability to exchange heat-load, thus delivering a higher capacity.
