HVAC Training Basics for New Technicians and Students! Refrigeration Cycle!

In this HVAC Training Video, I Show the Basics of how Refrigerant Flows Through a System, Saturated Temperatures, Phase Changes, Superheat, Subcooling, Airflow, Heat Absorption, and Heat Rejection! I Show Examples of Pressures and Temperatures! Supervision is Needed by a Licensed HVACR Tech While Performing Tasks as Experience and Apprenticeship Garners Wisdom and Safety.

Ok, this is absolutely the greatest video explaining a regular A/C system including both the components and the physics behind them. The diagram at 0:36 paints simultaneously and intuitively the pressure, the temperature and the refrigerant phase throughout the entire system. This diagram is brilliant! The example of pressures and temperatures at 3:44 is also very informative. I am not a HVAC technician but I am into physics and was looking for detailed physical explanations of what different components are and the transitions of the refrigerant between these components. Amazing teacher. Definitely subscribed!

Thank you! You helped me understand where the turning back into liquid happens. If the compressor is only a gas/vapor compressor I was wondering why it didn't self destruct from compressing vapor into a liquid. But I see the "condensing" happens down the line a bit more gradually.

With so many compressor failures due to being hermetically sealed, curious why windings are not separated surrounded by refrigerant to cool to isolate the windings

They don't need to be separated to be cooled and that would diminish their magnetic force when electrical power is applied, thanks!

my question is why does the refrigerant need to be heated up and turned into vapor before lowering the temperature to get cold air coming out?

when air contaminate r410a will it dissolve like alcohol and water, or water and oil? would it be too hard for the compressor to squeeze and make a hitting noise?

I was asked about the refrigeration cycle but was told I was wrong on the evaporator side saying low pressure low tempature vapor.
