How do air conditioning units work? Air conditioning system basics. We learn basic refrigeration cycle, compressor, condenser, evaporator and different types of expansion valves.
Correction:
06:08 The bulb refrigerant expands to *OPEN* the valve, not close the valve. Letting more refrigerant in.
06:10 *CLOSE* the valve, not open the valve

You are a REAL engineer !! ❤
Great explanation. 👍👍👍👍👍

Your good😎
Thanks so much
I needed this
Who else searched for this video!?
Hello,in MALAYSIA please 🥺
the evaporator and the condenser …. left or right, in one scene it is on left, then it switched position, a bit confusing.
This is a type of heat exchanger with a coating applied for the only purpose of dehumidifying, or "drying", the air stream before it enters the home. What is it? Can somebody help me with this question?
This is a good overview but the compressor usually discharges to the top of the condenser and the vapor will condense to a liquid in the bottom few rows of the condenser. I know the graphic looks cleaner the way it's setup but I feel like it's a little confusing.
How does one choose which refrigerant is best suited for which hvac system?
Another 1st class production, easy to understand, and, in plain language. Im going to pass this on to our younger trainees, thanks.
By the way, R22 colour is green, R410 is pink in NZ.
id like to ask. evaporator in my acc has 3 sections which are labeled as top, middle and front.. when i turned the ac on, only the middle one became cold, whereas the other two were not. i touched it during checking. is this because of the bulb malfunctioning which causes faulty feedback to the orifice controller valve?
the best basic so far. thank you for this video.
Believe me your videos save lots of lifes… 😉👏👏👏👏
QUESTION for those who understood video (coz im confuse a bit)
When we charge refrigerant in any basic split or window ac… through suction line with unit ON… we hold the refrigerant Can/cylinder upside down.. so that refrigerant can be charged as liquid… then why compressor doesn't get damaged???????????
So interesting science fair.
Good video for learners. As an Instructor in Airconditioning & Refrigeration , i would advice to correct spelling. ie. " Airconditioning ".
I'm currently a student at a trade school studying for a career as an electrician, and i will be sticking with it, but i think i might look into hvac one day
I have a question! How come the condenser unit can change the refrigerant from gas to liquid? As you said before refrigerant boiling point is -40degC so by forcing air over the condenser will still keep the refrigerant in vapour state???
Very nice / simple video.
Great Job sir.
When the FREON, the refrigerant, has normal air pressure 760 mm of atmosphere mercury pressure, it is the liquid. But it it will be under the pressure, it will boiling into vapor in the less high temperature. Why it is impossible to make tea in the mountains? Because the air pressure less in the high place and the water will boiling in tye temperature less that 100 °Celsius. The boiling point will be at 80° Celsius. So, the refrigerant has the same – it will boils in less temperature inside the pipe if warming it up with the heat wire. But after it traveling in the pipe till the cooling down, it became the same liquid, which will get into heating camera till evaporated another time. Those refrigerators are less powerful, but ur is enough to have cold beer or the frozen ice cream in it.
How it is HARD to understand!
My knowledgre of the refrigerators – was as like that, the pressed refrigerant got expanded, and that cools it down till the low temperature. The blower is needed to cool down the compressor, which got hot from the pressing the refrigerant till the high pressure.
But some refrigerators may have no compressor. The small kind may have the only heater. That makes the refrigerant hot, and it changes its condition from the liquid into vapor, that will press into small hole of the valve into expanded camera, where the expansion will make the cold pipes which will be cooling down the freezer part of refrigerator. But after, the cold vapor proceeded into heater in the fluid form because under the pressure its boiling point became in low temperature.
Thank you so much
