The physics of air conditioning in under one minute

Using the ConsuLab EM-2000-YF trainer, we demonstrate the complete r1234yf refrigerant cycle including the change of phase from liquid to gas .

The ConsuLab EM-2000-YF R1234yf Air Conditioning trainer is a complete A/C system with unique features designed to enhance the instruction of air conditioning physics. The trainer uses the H-Block TXV design with R1234yf flow control. The trainer uses common automotive components and can be used in both classroom and shop environments. The trainer utilizes a hermetically sealed and internally protected compressor.

ConsuLab offers four EM-2000 variants, each showing the change of a phase. There's an orifice tube version, an H-Block version, a TXV version and the latest refrigerant r1234YF (demonstrated in this video).

Great vid, but I feel like I know less about air conditioning now lol

[havefun]

I've been in hvac for 32 years and never seen a system this full of complexities!😮😂😂

The h block is basically a thermostatic valve which uses the second stream as the sensing bulb

[n.gineer]

The unexplained “H Block” which has to be a TCV with recycle sensing instead of the classic bulb? This is no ordinary Air conditioning system.

Videos like this, while great, show me just how dumb I am, lol. Definitely respect for those who work in trades and learn all of this.

Anyone that's not in HVAC, this will sound like mumbo jumbo lol

I remember having to build out a refrigerator like that from scratch in school.

I like how they say "twelve thirty four" because it sounds more serious business than "one two three four" 😂

[DelightfulTrain-kmxe]

Now I'm more confused than I was before the video,
But best explanation ever heard

[coldfingersub]

Good trainer especially including the latest refrigerant with internal heat exchanger in multiple see-through glass tubes

New type of metering device? This seems cool

[tinytattoomike]

I still don’t get it the whole idea of boiling and heat screws me every time

[RobertMillerJustme]

I want a old ammonia compressor - the whole scam of changing freon types that force you to upgrade what should last 60 years every 10 years sucks

[bassman]

For an explanation for the lay person, this is a bit overcomplicated. Yes all those parts are required for an efficient reliable system, but thats a lot more than is needed to demonstrate the cycle...

Expansion Valve is the key to understanding any system.
What is happening AT expansion tells you everything about the system.

thank you for the knowledge, greetings from me ac technician in Indonesia

[notsosure]

Two days in to my F gas course and I actually understood everything you just said 😎

[terrycarter]

What's the reason for the internal heat exchanger? Why would you want to heat up the incoming charge? Trying to cool down the incoming gas to the compressor?

[TheHomelessWelder]

I lost him at the start. Looks so complicated that I don’t want to deal with it. Who needs air conditioning anyway. 42 degrees Celsius today.

Damn so this is what's in my textbook?
