I have registered and completed 1 online e-class on their website. It was Great !!!

actually, two termocouples are used to measure the "input" and "output" stream temperatures and than a sufficient fan speed is calculated to do not produce any liquid, but just vapor, else the pump will stop to prevent damage and the cooling capacity will drop, that is why you should always let the AC be in automatic fan mode. it will calculate the suitable fan speed to maintaining the cooling capacity you need to maintains the room temperature you requested.

Can someone give an everyday example of "when vapor releases heat, it condenses"? I still don't get the idea of vapor release heat

Bitch they made it worse by environmental problems

Air conditioners can negatively impact the environment in the same way that other machines that burn fossil fuels do: by emitting harmful by-product gases into the atmosphere. Most air conditioners are fueled by electricity and use a refrigerant that results in gaseous emissions that contribute to global warming and ozone layer depletion. In fact, some studies predict that by 2050, roughly 25 percent of global warming will be caused by air conditioning.

I mean thermodynamics is pretty simple, hot travels to cold, the bigger the temperature difference the quicker the transfer.

Bryan Lee when you press two opposing sides of a spring together, you are compressing it. Similar thing happens but with Freon gas. In the physical world, as a gas is compressed, it also increases in temperature. Once that compressed gas is cooled, and it is then allowed to decompress via the expansion valve. As compressed gas is introduced to a lower pressure, it naturally cools, giving the evaporator the coolness it needs to blow air across the coils to blow the cold air into your house.

@@iamthehenke No gas is decompressed in the expansion valve. After the condenser, the refrigerant is in liquid state.

@@axeljmiller3757 for me it was locks. How do locks work? Cool little mechanical puzzles. Even got some clear acrylic ones where you can see what happens inside.

Compressor is like a pressure cooker, higher ambient pressure enables the coolant to stay at higher than normal temperature which enables heat to be driven out into the relatively cooler atmosphere. The expansion valve does the opposite, it decreases the pressure of the coolant so it's boiling point is lowered and it becomes a gas easily and the energy required to become a gas from liquid is achieved from the coolant temperature itself, so it drops. Combining two processes happening at the same time is what air conditioning is 😁

Ewan Qu naw dude repetition is key 🔑. Watch it more than once and other video

Well everyone is "dumb" at some point. Smart people admit they know nothing about something to open up their minds to learn something new. A person that "thinks" he is smart, will start to question themselves for not understanding on the first try, blaming genetics. Just admit that you don't understand and take the time and effort to understand. It took a lot of effort from even the best scientists with brilliant minds, through trial and error, to even get to the moon--they didn't get it the first try either. Every trial that failed didn't discourage them, because they knew they were getting close to the answer with every failure.

Compressing raises temp. Stuff gets compressed. It heats up. Pipe moves hot stuff outside. Hot stuff goes away. Warm stuff comes inside. A part of the pipe that is small cools it. It cools it by letting the coolent sweat(evaporate and use up energy).

1.Compressor inlet receives room temperature with low pressure(pressure already reduced in expansion valve.). 2.condenser will reduce the heat coming from coppressor.

I like how you compressed your comment into a tight joke. That's hot flow. 🍻

Be careful, the left wing wackos hate when the truth is told out loud.

Nah you got it wrong. It's expelling heat from one part and absorbing heat from the other. In other to absorb heat from the evaporator it creates something that would have turned to ice if the fans blowing it inside the room wasn't there. Since the fan is there ,it Blow's it in just in time before the ice builds up. But then there would still be ice, so that's where there is a pipe to leak out the water outdoors. Lol the guy couldn't explain coz of time but well

@@conqwiztadore2213 pump works on liquid while compressors for vapors

kzfaq.info/get/bejne/f65peJN_m5uripc.html

Its simple. The basic principle is that when liquid evaporates, It absorbs the heat around it and cools the surrounding. That's why you feel very cold when you come out of a shower. The water on your skin evaporates and absorbs the heat on the skin and cools your skin. The same principle is used in ACs and Refrigerators. Here instead of water, a liquid (refrigerant like freon (cfc)) is used. It has very low boiling point and very good thermal conductivity. Because of its low boiling point, it evaporates easily in the room temporature. This refrigerant is pushed into the evaporator ( ac unit inside the house) in liquid form. The evaporator coil is continuously blown by a fan (ac unit inside the house) and the air blown by the fan passes through the evaporator coils and enters the space which needs to be cooled (room). When the liquid refrigerant enters the evaporator coil, it evaporates into vapour because the coils are exposed to the normal air blown by the fan.( low boiling point). As it evaporates, it absorbs the heat in the air blown by the fan and cools the air. That cool air enters your room and reduces the temperature. That evaporated refrigerant from the evaporator needs to be turned back into its liquid state because the ac/refrigerator system is a closed cycle. You need to reuse the refrigerant in a continuous cycle. So the evaporated refrigerant is pushed into the compressor driven by a motor (ac unit outside the house). The compressor compresses the refrigerant vapor and turns it back into highly compressed gas. But when the vapor is compressed, it becomes hot. Now the highly compressed hot refrigerant contains all the heat it absorbed in the evaporator and all the heat which is produced during compression. It needs to be cooled. So it is pushed into the condenser where the hot pressurised gas is cooled by passing through coils being cooled by a fan (ac unit outside house). When it gets cooled, hot compressed refrigerant gas condenses back into liquid. This liquid is sent back to the evaporator again for evaporation for further cooling the room and hence completing a cycle. Now there is a device called thermostatic expansion valve between condensor and evaporator. It basically controls the amount of flow of liquid refrigerant into evaporator. When the room is hot, refrigerant can easily evaporate so the expansion valve allows more flow of liquid refrigerant into evaporator. But when the room is already cold, the refrigerant doesn't vaporise easily like when the room was hot. So the expansion valve reduces the flow of liquid refrigerant into evaporator. This control of flow is important to ensure that refrigerant always leaves the evaporator in a vapor state. Because if the refrigerant leaves the evaporator in a liquid state, it will enter the compressor in liquid state. Since you cannot compress liquid, allowing liquid into compressor will damage it and reduce its efficiency of compressing. That's why the expansion valve always keeps an eye on the evaporator outlet using a sensing bulb and maintains the liquid flow to evaporator ensuring complete evaporation inside evaporator. Your ac/refrigerator contains smart monitoring system and controllers to maintain the required temp by controlling the compressor motor speed hence controlling the flow speed of refrigerant in the cycle. This is how ACs and refrigerators work. I am a marine engineer and I work with big refrigerating plants in ship. I hope this helps you understand.

@@SuperGuruoo7 we need people like you in engineering video comments, thanks a lot man

Give it some time, friend.

Are you smoking something?

Doctor Cornelius That was extremely helpful and easy to understand!! Thanks, now I understand how it works🤗

John Ratko No but I lost it at the part where it explains the expansion valve...

No this video is bs they don't know what they are taking about

That's where the trickier part is, to understand it better and easy let's first address the tricky part. As the bulb works with the exit part of evaporator coil, needle works with the entry of it. By taking the input from the bulb at the exit, needle adjusts itself at the the entry of the evaporator coil to determine how coldly or hotly should it send the registrant(Liquid+Vapour) into evaporator coil. For suppose, if the bulb isn't recieving the refrigerant at high temperatures than the room temperature then it let's the needle know that it's time to decrease it's inlet valve size in order to make the refrigerant even more cooler while entering the evaporator, so that the higher room temperature around the evaporator will help refrigerant evaporate into vapour state completely while leaving the bulb.

@@ambidekstrusful, the inverter system also controls the evaporator temperature and so does the TXV. How do they collaborate?

@Naleen Silva Not exactly. Yes, the invertor system(compressor) controls the temperature of evaporator. While TXV only makes sure of sending back the liquid from the evaporator in its purest vapour form to the compressor. TXV uses Bulb to interact with evaporator's temperature and adjusts it's needles valve size.
