Thanks! Share it with your friends!
Is the condenser removing the indoor heat as well as reducing the temp of the refrigerant from the compressor.
Excellent video, this is the right way to teach the refrigeration cycle to new and prospective hvav technicians!!
I'm studying 5th Class power engineering here. I'm already a plumber, so I've got the boiler stuff down pretty well. The refrigeration side though, is the next largest part of the provincial exam. I know very little about refrigeration. This is the best video I've found yet. Thanks
Thanks in a million. Great content. Awesome. Grade: A++💥
This video made abundantly more sense than the semester of Thermo that I sweat through (no pun) in college! Thanks for a great explanation!
Great job sir!
Awesome explanation, Thx
The best instruction so far!
This is a great video and fantastic explanation of the refrigeration cycle.
Wauy this video is amazing, they way you express the circle is perfect great video boss 💯🙏🏽✊🏽
This was well presented but it contains one flaw common to every refrigeration cycle explanation I have ever encountered. The job of the compressor is not to increase the pressure; its job is to increase the temperature. It accomplishes that job by increasing the pressure. I believe that one of the reasons so many people struggle to troubleshoot refrigeration systems efficiently is because of this inappropriate elevation of the importance pressure change in the cycle. Of course, it is important but the job of a refrigeration cycle in an air-conditioning application is to absorb heat from cool indoor air and shed it in warmer outdoor air. The heat absorbing coil must be cooler than the indoor air it is absorbing heat from, and the heat shedding coil must be warmer than the outdoor air it is shedding heat too. To do this it would be obvious to the student that there has to be a mechanism in the cycle to make the outdoor components warmer than the indoor components. To me it makes more sense to explain that this is the job the compressor does, raise the temperature, and to explain that the metering devices job is to lower the temperature. Then explain that the compressor raises the temperature by raising the pressure and the metering device lowers the temperature by lowing the pressure. Temperature change is PRIMARY, pressure change is just the means to that end.
The refrigeration cycle contains five basic components: a heat carrier (refrigerant), a heat absorber (evaporator), a temperature increaser (compressor), a heat shedder (condenser), and a temperature reducer (metering device).
You'd think I'd understand superheat and subcool by now, but I didn't until this video! It's just the temp above and below boiling point, now I get it!
I still view the refrigeration cycle as the closest thing to real life magic I know besides flight.
I have been watching many videos, I heard the superheat/subcooling over and over. With the explanation here, all makes now sense. Thank you, thank you.
