      Hi there. Great video however, FYI could you just slow down a little. I had to keep pausing on some sections. Other than that I'm a heating engineer in th UK who's looking to get into refrigeration, so your video was extremely clear and informative. Thank you

    The fact that I sat in a 6 hour class on this subject, and still didn't get it, but watched a 4 min video, and now got it down is sad! these trade schools just want to take your money and push through their program as fast as they can! It's really a shame because guys graduate, get their certs, and can't answer anything when it's time to interview.

    Saturated state:
    Where vapor an liquid coexist
    High pressure high temperature vapor into condensing unit after compressor.
    High pressure high temperature sub cooling in the condenser
    Low pressure low temperature into evaporating unit after the expansion valve.
    Low pressure low temperature super heating in the evaporator unit.
    It is latent heat rejection & condensation followed by sub cooling in at high pressure and temperature inside the condensation unit
    It is latent heat addition followed by super heating at low temperature and low pressure after the expansion valve inside the evaporator unit.

    Not like anyone reads these comments but for easy understanding, correct me if wrong but the system has a split at either the compressor or the metering device. These points are doing the opposite of each other. With the same point being made for the condenser and the evaporator. The condenser does the opposite of the evaporator but by the same process. The metering device begins low pressure and temp, and the compressor begins the high pressure and temp. The whole process is a change from a full vapor to a full liquid and by understanding the main components essentially do the opposite of each other really simplifies the cycle in the brain.

  • @chiliboom6140
    @chiliboom6140 2 місяці тому

    I just started apprenticing in commercial refrigeration. So we deal with walk-ins.
    My original understanding of the subject was that something cooler than another thing will draw the heat to the cooler thing, thus removing the heat and making it cooler. In a walk-in fridge, the low pressure side coming into the fridge and through the evaporator coil is warmer than the air in the fridge. How is the warmer thing taking out heat from the fridge that’s already cooler? I really hope that makes sense. Please remember I’m just starting to learn; go easy on comments please. Lol

    hi Thanks for your clear explanation of Refrigerator Cycle. I have one rather important question I would like to ask. Your Airflow where does the Air come from. Is it normally a Close Loop System where the Air is constantly re-circulated by the Evaporator Fan in the Fridge, or is Fresh Air Intake going on so that the Evaporator Fan is constantly pulling Fresh Air from the Outside and blowing it through the Evaporator Coils inside the Fridge. Also if it is not a close Loop System and the Fresh Air is constantly being sucked in from outside , is it vented out as it is recirculated inside and replaced by a fresh stream of air. Thanks

  • @jesses9553
    @jesses9553 2 роки тому

    Great explanation.
    Why do I always hear “the heat is dumped outside,”” (at the condensing coil). Indicating that the heat you feel from the outdoor unit is from inside the building?

    • @chiliboom6140
      @chiliboom6140 2 місяці тому

      The low side(cool side) absorbs heat from within( for the sake of example) your house. There’s an area where the warm air in your house can contact the evaporator and draw the heat in, thus cooling your house. The refrigerant that has absorbed all that heat from the warm air then travels to the condenser coil, outside, where a fan connected to the unit blows all that out of the condenser. Hence ”dumped” (blown off)it out outside.
      This is a very simple and shortened explanation. Any others who read this can give their two cents on my explanation.

    Wouldn't the condenser fan motor be sucking air through the condenser, not blowing it out. Usually I put a piece of paper on the condenser to see what the fan is on, when it's on it should stick.

    This may be stupid as I am only an installer. But if Freon has a lower boiling point, how is it a high temp liquid going into the evap coil, but a low temp vapor. I figured high temp &/ high pressure would evaporate the Freon going back to the condenser
