Hello everyone and welcome to the new episode of the HVAC Education Hub Channel.
In this episode, we'll cover the difference between R290 (propane) and R32. As you know, European Union and F-gas regulations are going into the direction of natural refrigerants, with a few years of phase-out of older refrigerants, such as R32 or R410.
With natural refrigerants such as R290 (propane), we can go on higher water outlet temperatures. We will explain how. But, this refrigerant is flammable. So, we need to take care that our area is safe and our possibility of refrigerant leakage is minimal.
If we compare R32 and R290, we can see that with R290, we have higher temperatures and lower pressures - critical points are 43 bar and 96 °C. And on R32 we have 58 bar and 78 °C. This means that we cannot condense on higher temperatures on R32 because the high-pressure limit on all devices is around 40 bar.
