  • In this HVAC Training Video, I Show How to Explain Subcooling and Total Superheat to an Apprentice. I Show Where the Measurements are Taken, Tips to Help You Remember, and What Exactly these Measurements Mean When Checking the Refrigerant Charge. I Explain Undercharged, Correct Charge, and Overcharged. Supervision is needed by a licensed HVACR Tech while performing tasks as Experience and Apprenticeship garners Wisdom and Safety.

      Desperately need an answer. I am going crazy. ASSUMING a system is working properly can you determine the correct charge level with the sub cooling? In other words if you know the temp of the high line and the pressure of the high line can you determine if a system is properly charged assuming the outside temperature is reasonable. I know most systems only post the average temp. but.

What you want to do is just like this dude said, be honest. I can tell you from experience, a good work ethic is worth TEN TIMESall the knowledge in the world. If you have a good work ethic, I can teach you anything you want to know about this industry. But without a good work ethic, and all the knowledge in the world, you’re just a lazy bum, nothing more. Good luck to ya buddy, I’m sure you’ll do well… or should I say, I’m sure you did well. One thing I LOVE about these unions, they’re not satisfied with making you a limited journeyman. When they get done with you, you’ll be a master of this trade. Congratulations, make the most of it…

    Wow Craig that's the best definition of "saturated" that I've ever heard!
    Previous explanations just explanations just told me it was a mixture of liquid and vapor. You clarified that at this point it is not changing temperature. but only changing phase. For 12 years since Tech school I have understood super heat and subcooling but "saturated" has been sort of vague.

      As an engineer, but former tech, I enjoy watching such videos (usually the result of researching test equipment though). Overall, good explanation, just might have started with definitions of terms first (but that is just more preference in presentation). As mentioned in the video, or to make it more clear…
      The temperature of the refrigerant decreases during the desuperheating and sub-cooling processes, but remains constant during the condensing process itself (gas to liquid, or as in the video the “saturated section”). The energy rejected from the refrigerant heats the secondary medium (copper or aluminum), whose temperature thus increases. However, The refrigerant pressure changes little from desuperheating to subcooling (think compressor to service valve). In a similar way to evaporation, the only pressure difference between the entrance and the exit of the heat exchanger is just the pressure drop (the equation is: pressure equals temperature times volume - which explains why your car tire pressure only changes with heat, but is the same wether mounted or not). Also, because the flow velocity in a condenser decreases, the induced pressure drop is much lower than in an evaporator. In other words, the pressure is rather stable throughout the high-side and low-side environment (between condenser and the expansion valve / orifice and vise versa).
      Another key thing to remember, is that phase change is what takes the most energy (yet pressure is still rather constant). Thus, most heat is transferred during the condensing process (that process which is after desuperheating but before subcooling). Another mental tool I use to think of saturation is relating it to the opposite as in precipitation of say minerals from water; boiling water causes dissolved solids to precipitate (due to temperature change).

    exactly the explanation i needed. An explanation looking at a diagram just doesn't click. Having the gauges and condenser there and instructing how it would be done in the field is much better.

    Cant recommend this book enough. So simple to read and understand. Im not a tech so I dont service hvac systems enough to have this material become second nature. I read it last year, but forgot some stuff by this year. I decided to read the book again (something I would normally never do), and found it just as enjoyable as the first time i read it.
