Nice job breaking it down and explaining it to Joe home owner my friend. You should do a 2nd one explaining how it works as a heat pump and a third one explaining natural gas and oil heating. Explaining how Heating, ventilation, and air conditioning work and what is broken/not working is hard to do without sounding like you’re being condescending or like the customer is beneath you is hard for me and my friend you have a gift explaining it. At least to me you do and now I can show them this video of it.
Emerson makes 90% of the world's compressors. Their Copeland scroll compressors are very durable, and can actually handle a little bit of liquid refrigerant passing through it without damaging it. When I went to school and learned about the refrigeration cycle, I began viewing the cycle as starting at the metering device. That's where the cold air starts, and, in my mind, where the entire cycle ends and restarts a new.
Nice explanation. I think your ahead of the game dude. The TXV does create a pressure difference, but I've always taught people that the TXVs main job is maintaining superheat and creating a pressure difference. Scrolls can take some liquid but not intended to, flood back means something else in the system is not right. Defective TXVs are one of the hardest problems to diagnose in the field, usually after checking everything and adding a few LBS of gas tech realize TXV not working. TXVs job is to eat quality liquid and modulate to maintain suction superheat at compressor. The refrigeration cycle can get more involved with Cascade machines and Kraus MRI chillers. Good luck man. May all you sight glasses be clear. Oh yeah… they don't use sight glasses anymore. May all your 2 second acid tests be negative, they probably don't use those anymore either. Oh well… Hope your refrigerant sensors in the new air handlers go off and lock out refrigeration cycle so houses don't blow-up. Haha just kidding. I'm sure we will all hear this over the next few years.

Thank you!!!!!!!! Taking my airframe at 8am tomorrow. I have really bad dyslexia and right up till the night before I still get it mixed up…. I'm so screwed.😐

Thanks man, a very intuitive explanation
I always picture it counterclockwise

Is the "metering device" also known as the thermostatic expansion valve? Or is that at another point of the cycle?

Amazing
Refrigeration
Where is the cool pulled by the condenser to comdensate the refrigerant coming from?
Where are you located in Nakuru for training
Bruh you explained part of it you completely slipped the evaporator
