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

Thanks for explaining so well in few words. 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.

Absolutely powerful video and great detailed explanation! I went to trade school back in 2009-2010 and graduated knowing very little about hvac. This 4:34 minute video explained more to me than I ever learned at trade school. Wow. Thank you for sharing!!!!!!
I just passed the EPA universal certification test. I was using SkillCat app and going through the program only once and passed the test within one week. I do have some background in HVAC and chemistry though.
Very good and well-explained video. I'm taking my EPA 608 test tomorrow, this will help keep it fresh in my mind. I watched several more of your videos and am now a subscriber, so I'll be seein' ya! 😄
thank you so much for this, its helped me understand refrigeration cycle in full. I was having trouble fully understanding some points in class and this video along with your superheat/subcool have cleared those issues up for me. subscribing to your channel for sure!
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
great video man. You saved my physics grade. We had to explain how something works and i got an AC. I was so confused until i saw ur video. Keep up the great work
Great video! Refrigerant is amazing stuff huh, just manipulate it's temperature/heat transfer abilities all by pressure. I am starting to grasp the concept
Yes it is, great to hear! I am glad that you enjoyed the video and that you understand the cycle more! Hear is another on the refrigeration cycle video using a unit to explain---------ruclips.net/video/qqLwE7Kbyaw/видео.html
Absolutley Awesome ive watched this 10+ times can you please do one on a gas furnace. startingg from checking the draft induced motor and going over each step and part all the way too the blower?
Great video really helped further my HVAC knowledge. I just want to clarify that when the low pressure low temperature vapor leave the evaporator coil it is superheated right ?
FANTASTIC Video and the best video that talks about the refrigeration cycle. I'm currently designing a condensing unit and do not know exactly what size of galvanized metal sheets to use for its protector body. You have mentioned that you have a sheet metal teaching license. Can you help me with that aspect, please?
Thank you for your valuable information. Do you have any videos or Book about A2L refrigerant safety, tools and where can we get certified to work . Thank you
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

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?
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.
@@acservicetechchannel Thank you. I have been following your channel for some time now and have recently started taking an HVAC/R course. Your lessons here are better than the ones at school.
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
Are their rule of thumbs for ideal condenser, evaporator, discharge and suction temperatures? Would their be a point where increasing evap airflow causes temperature to increase too much? Would their be a point where increasing condenser airflow decreases the gas temp be too low?
I am trying to finish up the one that I am working on. It is quite a lot of working getting all of the pictures complete but I can let you know when it is complete if you send over an email to info@acservicetech.com thanks
I have a QUESTION as a learning student. Why does the temperature increase after the evaporator, after changing from liquid back to a vapor? I thought it was supposed to increase only after being compressed by the compressor.
Because heat is being absorbed by the refrigerant while it's flowing through the evaporator. The fan is blowing warm air from the room over the cold coils, the heat from the warm air is absorbed by the refrigerant as it passes through the evaporator coils. Since the pressure is lowered downstream of the metering device, the refrigerant vaporizes at a lower temperature. So as the refrigerant absorbs the heat, it's temperature rises, and it vaporizes. The compressor compresses the refrigerant and increases the pressure as well as the temperature. Now that the pressure is higher, the temperature for it to change states is also higher. As it passes through the condenser coils, the air flowing over it is cooler than the refrigerant and therefore the heat is transferred from the refrigerant to the air, dropping the temperature of the refrigerant and changing from a gas to a liquid state.
I'm sorry, I really appreciate your magnificent content, but the heat is a result of compression/decompression of the refrigerant gas by the expansion happening in the condenser unit.❤❤

I have a QUESTION as a learning student. Why does the temperature increase after the evaporator, after changing from liquid back to a vapor? I thought it was supposed to increase only after being compressed by the compressor.
Because heat is being absorbed by the refrigerant while it's flowing through the evaporator. The fan is blowing warm air from the room over the cold coils, the heat from the warm air is absorbed by the refrigerant as it passes through the evaporator coils. Since the pressure is lowered downstream of the metering device, the refrigerant vaporizes at a lower temperature. So as the refrigerant absorbs the heat, it's temperature rises, and it vaporizes. The compressor compresses the refrigerant and increases the pressure as well as the temperature. Now that the pressure is higher, the temperature for it to change states is also higher. As it passes through the condenser coils, the air flowing over it is cooler than the refrigerant and therefore the heat is transferred from the refrigerant to the air, dropping the temperature of the refrigerant and changing from a gas to a liquid state.
So when the liquid comes out of the condenser it is just high pressure liquid. What would be the temp.
How much of a pressure change coming out of the condenser? Since heat corresponds to temp.
Awesome video series.
Sigh, yet another guy who manages to better explain in 4min what my prof couldn't in 2h of lecture.
Great Job!
