Global Warming potential is Irrelevant! What is relevant is the efficiency since our two maximum efficiency refrigerants(R-12 and R-22) have been banned.
The Global Warming Potential (GWP) on a commercial level indicates the lifespan of a refrigerant in terms of environmental restrictions. For example, if the GWP is around 1000, it is low, but already at this point, there may be environmental restrictions. In the case of R290, it has an extremely low GWP, suggesting that it will be on the market for many years. Thank you for participating.
The asian evaporator coil copper tubing is "very poor quality copper" it is thin and corrodes then leaks. If there's a explosion and someone gets badly hurt, the customer's lawyer will b e contacting you saying you were the last person to work on it. There goes everything you ever worked for. I don't want the liability. I change the cap tube and refrigerant. I've seen a lot of stuff in this industry come and go, I expect 290 to be gone in a number of years.
I do not understand? why the temperature in the evaporator coil is lower when the pressure on the low side is lower aka is 'low' on refrigerant? To me it would be logic if it was the other way around. Can someone explain that?
Here's the previous response translated into English: When there is lower pressure, a liquid evaporates more easily because its molecules separate more quickly due to the reduced force they need to overcome. For this reason, at lower pressures, the liquid boils faster and requires a lower temperature to reach its boiling point.
@@CSTChillingSolutionsTraining Thank you very much for your answer. This sounds logical and I need more time to let this sink in to understand it regarding to the sealed loop system. Thank you!

Nope! R290 has been around for a long time now everywhere else in the world, R290 is here to stay, you can say bye to R410A tho 😢

290 would be great if they could add a fire retardant to it
