Supera Video (Superheating and subcooling in practice in a cold chamber) Hi everyone. I see a lot of people asking about what procedure should be adopted in relation to the thermostatic expansion valve, whether to open or close it, and when to open and when to close it. So I decided to record a very amateur video, but showing in practice the superheating and subcooling in a cold chamber that also serves as a frozen chamber, from the measurement of SA and SR, we must take some action, such as opening or closing the VET or simply adding or removing refrigerant fluid. In the video I also teach how to do superheating and subcooling in practice in a cold chamber. May God bless our lives and have a good week. Thank you for all your support. superheating in practice
