In this HVACR Video, we go over the purpose of a Liquid Line Receiver in Refrigeration Systems and why Receivers are not used in Comfort Cooling systems. I go over what component forces the liquid into the storage tank receiver, what keeps the compressor safe during varying load conditions, and why the receiver is so important.

Supervision is needed by a licensed HVAC Tech while doing this as Experience and Apprenticeship garners Wisdom and Safety.

These Videos are all part of our Training Series on HVACR Service, Installation, Preventative Maintenance, General Knowledge, and Tips. Please comment and ask for videos that you would like to see in the future! We come out with new videos every few days from my job sites, service calls, and the training shop! I hope you enjoy and find them very beneficial! See you next time at ACSERVICETECH Channel!

    Thank you very much for making these awesome videos and sharing your knowledge. Your videos are very helpful. Could you please make a video about defrost timer wiring and defrost cycle. Thank you!

  2. HVACR Northeastern says:

    Good video when you have and receiver and you don't know what level little trick is use a  the small solder torch and move it a long side it will get cold and that where the level is where is start to frost.

    Thank you so much!
    So when someone says they are closing a valve and "pumping down a system" this is a service valve that stops the flow from the receiver to the TVX? The compressor keeps pumping until reaching near vacuum, a low pressure switch then turns off the compressor and the majority of refrigerant is trapped in the condenser and receiver?

    So what is the purpose of an accumulator?
    Are there systems that have both a receiver and accumulator?

    Your vids are PRO. I would like to see you as a guest on the podcasts of Cowboys of HVAC or HVAC School. I have 12+ yrs in commercial and your vids never get old. I am always picking up something from them.👍👍👍

  6. Boxing 101 says:

    Awesome video , I was always under the impression that the receiver was there to receive liquid back to the condenser when the box temp was satisfied and the solenoid closed (allowing the the unit to pump down )…. Btw , your tutorials are impressive. Thanks again for sharing the knowledge .

  7. Licheer Bush says:

    Thanks for the information! Really liked the video but this didnt answer a question that's being brought up at work. I fully understand that subcooled liquid refrigerant is suppose to enter your metering device but my question is: what would happen is vapor refrigerant entered the metering device? What effects would that have on a system.

  8. JaffeJoFur says:

    How is it you're measuring superheat with a TXV? Shouldn't you be measuring subcool? Or, is it different for walk-in refrigerators as compared to traditional comfort cooling?

  9. Alice Pet says:

    I am learning compressor oil flows in AC refrigerant systems. The condenser units of walking in freezer/cooler are normally sitting on the roof which is lower than evaporator. Is there any oil trap on these condenser units? Can you do a video about compressor oil travel in different systems? On an AC system if all refrigerant leak out, do you think if it is necessary to add more compressor oil? Is there any different effects on oil lost if the leak from liquid line close to compressor and leaks on suction line? and how to charge POE compressor oil when retrofit from R22 to newer refrigerants? from suction line or liquid line if the compressor is not removed from the system?
    I am learning by myself. I have learned a lot from you and bought your book. Thank you again!
