I just love it!
Very informative 👏🏻
How would one know if there is a compressor issue or an expansion valve issue? Symptom: Car is not cooling better than 65F at the vents on a hot day. It gets to 55F while driving. Condenser fan spins fine, system was evacuated, vacuumed, and recharged properly, drier replaced, but still the same issue. Low pressure 35, high 175 on 96F ambient temps. High pressure low and low pressure normal, seems like.
Beautiful Can you make a video about car ac compressor control valve how does it work ? will be helpful❤ Hope you share soon..
This system always breaks lmao. Would rather have my engine break than one part of this system go wrong. Especially on Florida.
Couldnt find the issue fill the feron but still hot air comp is engeed
The diagram is great but the explanation is a bit misleading. More than just oversimplifying, you used the wrong words to several places which will give novices the wrong impression.
Its kind of missleading. The system does not absorb heat from the cabin. It absorbs heat from the air that flows from outside when you turn the fan on.
What about when it is set to "recirculate"?
As an Hvac tech I always admire the compressors for vehicles, specially the 134a. They're very vell designed.
感恩了解，謝謝分享！
The evaporator is the most common leak area pin holes to be exact. It leaks in cabin most time you will taste it if it’s leaking. It’s in the dash board very labor intensive this is why people keep buying over the counter refills for 134. The new R1234 is very flammable and if you smoke in your car with this kind of leak guess what happens.
What does “very flammable” mean? It has a relatively narrow UFL and LFL.
@@yolo_burrito means cigarettes ignite it. Leak out your vent while you’re smoking you go up in flames. Look it up.
@@gunguy8348 it’s just flammable like Natural Gas not very flammable like acetylene.
Fake news my friend. Its just propaganda
The only question this video left me with is what happens to the condensation on the evaporator side in the passenger compartment? I know from window type air conditioners in a house that it creates a lot of water and that water drips outside, but in a car where does that water drip?
Exhaust
It drips out, usually through a hose to the ground.
Drips right below your car. Park in a humid climate and you'll see water below your car.
Ever car with AC has a small tube that lets the water drip under the car
But HOW is the pressure made by the high rpm compressor mantained? Is the pressure regulator an mechanic piece that moves preventing it from too little or too high presure? Thanks
The compressor doesn't increase the pressure of the refrigerant. It "superheats" the refrigerant into a liquid, forcing more energy into it so that it can remove more heat from inside the conditioned space. It is then "subcooled" in the condenser and turned back into a gas when the heat moves from the refrigerant into the outside air. The pressures simply just balance out between the hot and cold sides of the system.
@@user-et5mz5ex9s What are you talking about? The pressure absolutely does increase. So does the temperature. This is why you have a low pressure and higher pressure side to every single refrigeration system. What do you think a manifold gauge measures? In a car the pressure is regulated by cycling the compressor on and off. The magnetic clutch is actuated and released to couple the pulley which spins with the engine to the compressor. It doesn't hold it exactly at one pressure, it varies a bit, but the expansion valve help to regulate the flow in the evaporator to keep cooling consistent. The high side pressure is measured by the sensor.
I'm now a certified AC technician with 20 years experience
Then why is my ac clutch not engaging, but it moves okay not freely but it's not seized. When I freon nothing happens it goes in but not blowing cold. Also when I turn my ac on it just blows hot air from outside or warm air. I really want my ac fixed I'm tired of driving in the heat
@@victorstrand3422theres a button on your cars dash that says "A/C" push it to enable it.
@victorstrand3422 something is not plugged in correctly or a motor under the dash is broken
@@victorstrand3422 take it to a mechanic. you’ll need several tools to check the system. Not worth getting them unless you work on cars everyday.
nice video bro, short and simple yet precise, but it seems to lack some enfo, anyway its still good 👍
Very good and simple explanation!
I hate car ac system there are so many things that can go wrong
I think only one thing go wrong a clear ac refrigerant. but refrigerant can dirt in many ways. if dirty blicked system and overheat compresor pistons and seal
Air conditioning systems are overall pretty reliable
@@tgw230 yea only the windows AC
@@dd___dcenjoy melting, I’ll keep my AC thanks.
😂

Sir the expansion diaphragm is controlled by what? Because I don't see thermal bulb.
By the pressure in the system
The thermal bulb is a part of the H valve
temperature bro, there's an element on the stem that is connected to the diaphram that reacts with the temperature, just like the thermostatic valve
Great video
Thanks for your video

It should be noted that this is an explanation for an automotive or “mobile” air conditioning system, and the valve being illustrated is the Chrysler H block valve. While some principles may be applicable to other types of systems, this is the only place where you are going to see both lines going through a valve. This valve is most commonly used on the Caravan series of minivans, manufactured by Dodge and Chrysler over the past 30 years. Typically, this valve is positioned at the top of the firewall.
Many manufacturers use this style. Nothing to do with Chrysler. Very common on tractors and semi trucks as well.
Hey hermano una pregunta❓ si yo le doy media vuelta a la válvula puede pasar más refrigerante

High pressure liquid , once the condenser has removed the high heat from compression and high pressure refrigerant gas , change of state and the receiver drier has filtered and most importantly separated the high pressure liquid from the the high gas bubbles still present , the TEX valve then , depressurises the high from gas to a LOWM PRESSURE LIQUID, and the state of change occurs from LOW PRESSURE LIQUID TO A LOW PRESSURE GAS AS IT ABSORBS HEAT !!!! As it travels through the evaporator!!!! Not a mist !!!!! The TEX valve controls inlet flow as it monitors exit temperature, thus a constant temp is achieved NOT like a FOT system that ‘ floods ‘ the evaporator, and the high pressure liquid doesn’t TURN INTO A MIST ONCE IT LEAVES THE TEX VALVE !!!!! THERE IS AN ERROR IN THIS POST !!!!!
Look who graduated basic refrigeration!
*promo sm* ❗
does dry clutch require a 4T oil as does the wet clutch?
Do you sell this machine?
yes

Hej, where did you make this simulation? What kind of sofware?
He stole this clip from another youtuber
Thanks
