Hello community, as an engineer I've been thinking of starting my own page regarding how things work, meant to explain questions people have. I'll try to post regularly, and if people want something explained so it makes sense, send me a request. I'm a mechanical engineer, and love the automotive world.
Cold Air Conditioning is really a compressor. An air compressor can shoot out cold air. If you shoot tire inflator air on your hands you can feel the cold air. Its exactly the same as Cold Air Conditioning. When you push Cold Air conditioning, it turns on the air compressor. The air from the air compressor goes to another chamber where it is stored. The excess water leaves the tail pipes. The Cold Air goes into your car from that stored tank.
You think that Compressor is Funny? When I went to Refrigeration School in the Air Force they had these Fat Little Cartoon Cops come out & Beat Down the B.T.U.'s with Night Sticks, & Drag them off to the Condensor to be Cooled Off! No, I'm not making it up. You can't make up things that funny! This was in the Mid 1980's & they were still hand drawing those Cartoons. That's what happens to Cartoonists that work for the Government on Training Films. They start to lose it! It was Police Brutality!
Ok heres my question. How does the refrigerant get evaporated and condensed? I dont think that simply passing through the coils will do it, there has to be another process going on. Can anyone explain?

does it have to turn back into liquid? When my air compressor works the tank gets really hot. when i decompress air it gets colder. So my question is would it be possible to use simple atmospheric air to do the same thing?
@cyberlord64 it can do the same thing. how ever if following this design it would not be as efficient. In fact this design of a/c very efficient because when gas expands it speeds up and loss energy due fiction. you never know because the energy need to taken is greater than the heat generated through fiction. however light gas like hydrogen the heat generated through friction is greater than energy it can intake when it expands.

@MrMrArrtt ,it's not only the compressor,it's the compressor,the condenser(coil + tank) + fan working together what brings the refrigerant (in its gaseous phase) to its condensing point (this part of the system increases the gas pressure by adding molecules and decreases its temperature by removing heat (which passes to the atmosphere (low temperature reservoir). 2EASY MAN !
@jorgecalivalle When you increase pressure, you don't "add molecules." You just reduce the space which those gaseous molecules occupy. The volume of refrigerant in the system is CONSTANT (... unless you have a leak;).
@walterbrunswick ,the compressor forces the molecules in the LPS to the high pressure side,the expansion valve lets the liquified gas go from the HPS to the low pressure side thus there's a continuous transfer of mass from P = nRt / V if you wanna increse P you must increase either n or T or/and decrease V.
At any instant mass in the LPS + mass in the HPS = constant ,given there's no leaks
@franfrank I was thinking the same thing! MY MOS (job) in the military is essentially to maintain AC units, so I was training and learning how they work and how to repair them for several months. I maintained the highest grade in my class for 80%+ of the course, and I still didn't understand what he was saying.
The diagram is the shittiest I've seen, and what he said hardly made sense, because he just kept talking and talking! This video REQUIRES a more precise diagram!
@animeaijin21 All air conditioners are designed essentially the same. The video here is just complete shit. I would recommend looking elsewhere for a more precise and educational video on how air conditioners work.
refrigeration has two processes the evaporation & condensation and it is affected by 2 factors the pressure & temp.. the lower the pressure is the lower the boiling point can achieved. it even boils at 0 deg. C to negative something.. instead of 100 deg C for normal H2O. there must be temp difference to obtain heat transfer during cycle. if the air temp has around 35C then the evaporator will absorb the heat which has a temp of about 5C only. so temp diff.. coz air cond means removal of heat
@redman1333 The smart people down-vote videos like this, because they're worthless. You learn more about air conditioners by reading just a single comment in here that is limited to 500 characters!
If you still don't understand what I'm getting at, tell me... what did you truly learn by watching this video? Was it more than what you learned from reading the comments? lol.
Yes this is also quite difficult to understand he chose a complex way to explain it & also talk to fast, there's no time to let what he said 5 seconds ago sink in or register because he's already gone on to the next sentence and there's some thing new to think about their too, so forget what he just said.
@raynhornzxz Heat pumps have a 3 way reversing valve that can actually reverse the refrigerant flow through the coils, making the inside coil either heat or cool. A very non-complex explanation.
But what i think your asking is how the unit is heating your house. most common from where i'm from is a form of gas-flame heat, which heats air in tubes called Heat exchangers, the blower of your furnace blows air across these tubes to warm the air thats being discharged out your vents.
@raynhornzxz Air conditioning is to condition the air, or room temperature, to your desire. The word air conditioning is often used purely for cooling a room, but is also by definition designed to heat a room when desired as well.
Heating is quite simple..... heating elements (rods), much like a clothes dryer... after they heat up a bit (say, 30s), the heater fan will kick on and stay on for approx 30s after the elements have turned off from when the thermostat temp is reached. That's it... lol
The liquid hits the metering device creating a pressure drop turning it into a 25% lliquid 75% gas the change of state allows for heat to be absorbed, 970 btu's worth. The liquid doesn't make the coils cold and the compressor compresses a gas and the heat is released in the condenser where it condenses into a liquid. You need a change of state to absorb heat and a change of state to release heat
i think you might find when the liquid evaporates it absorbs the heat out of the air in the room and releases outside in the condenser. remember...refrigeration is taking the heat out, not putting cold in
What determines the BTU rating for a given unit? I have a new 2 ton unit that is much too big. Which components do I need to replace to bring it down to 1.5 Ton.
@brightonmusic I'm not 100% certain on this, but I believe it is the combination of all the components that allows a specific AC to have the BTU rating that it does. For instance, how large the compressor is, how large the evaporator and condenser are all significantly influence heat transfer.
What I am certain on though is that a 2 ton unit holds 2 tons of refrigerant.... a SHIT LOAD! Without completely redesigning the thing, I don't think there is any other way to turn it into a 1.5 ton.
correction.. when the freon vapors come out the evaporator coils its a gas the gas is compressed by the compressor then it goes thru the condenser coils losses its heat and condense into a liquid... because the compressor cannot compress a liquid..
This is wrong. What happens is that the cold side of the coils (blue in video) has the potential to remove heat it becomes warm and goes to the red side where it evaporates the heat it removed from the room.
@UNIVERSITYHI Yes. To elaborate in better english (sorry, lol), the evaporator fan (the blue side), blows the warm air IN THE ROOM over the cold fins ON THE EVAPORATOR (blue side), and so you feel the cool air from the evaporator, while the EVAPORATOR (blue side) IS ABSORBING THE HEAT from the room.
Because it's a much lower pressure (see metering device), the BOILING POINT IS MUCH LOWER, causing the refrigerant to VAPORIZE (evaporate, per say), which will allow it to go through the compressor.
@humpreystrong No vapors are designed to leave the confines of the AC system. It is a health and environment hazard when that happens. It should NEVER HAPPEN.
What you are probably talking about is the moving air from the evaporator fan that is blowing cold air out. It is the same air that is in the room, only cold, because it's being blown through the evaporator find, which are cold. Heat transfer.
So NO, nothing in an AC system is pure oxygen... as also, pure oxygen is extremely explosive!
@asdfgoogle hey thanks for answering.. so ur saying that the air we breathe in an air conditioned room is the same air we exhaled (CO2) just recycled to being cold... is it healthy? i mean im always in an air conditioned room... anyway thanks man,, just want to learn ^_^
@humpreystrong Well... the air you breath isn't entirely oxygen, nor the air you exhale isn't entirely CO2. In fact, nitrogen makes up the overwhelming majority. For a detailed list of what elements make up our air at sea level, just google "What Is the Chemical Composition of Air?"
There is absolutely nothing wrong with it. It's 100% the same air that you would be breathing anywhere else in your house, except it's much colder.
@humpreystrong By the way, when you inhale, your body doesn't absorb all the oxygen. What that means is that when you exhale, there is still oxygen in your breath. That is how CPR works. It wouldn't work at all if our bodies absorbed ALL the oxygen. Google the chemical makeup of the air we exhale for more info on that.
Free inexhaustible energy is real!But Elite controllers don't want ppl to be free from the costs of energy,Get a motor that needs no gas or electric input at LT-MAGNET-MOTORdotCOM ,Start the revolution!
compressors & metering devices change pressure in order to manipulate the boiling point of the refrigerant. In order to change from from liquid to vapor, heat MUST be absorbed, and to go vapor to liquid heat MUST be expelled. Pressure manipulates to boiling point in order to bring about a desire for a change of state.
A great explanation. You now how the air conditioner keeps you cool in the summer months. And if the air conditioner needs repair, you know who to turn to—Horizon Services, Wilmington (Delaware).
@7477238 That is because of society. The entire world is in debt? How is that possible, because interest creates money that isn't real. So a country would borrow another countries money (which doesn't make sense, because that country is in debt as well), and then interest is pounded onto the loan, creating more fake money.... it's retarded. lol.
If you don't believe me, just look it up on CIA Factbook.
The world needs a RESOURCE BASED ECONOMY, not a money based economy.
@asdfgoogle Did I say the entire world is in debt? Maybe you should read the comment I was replying to since some ignoramus decided to comment. No need to give me a lesson in money, I ain't got much ;)
@7477238 I got the questionmark placed in the wrong spot there. lol. That was actually a statement. The entire world IS in debt! But I was mostly just saying that in case you or someone else wants to know a little more (assuming the individual reading doesn't already know). I'm sure you were just trolling anyways. lol.
This was cool. We had a full chapter in our physics book in high school about coolers and how the fridges work. The chapter was difficult to understand and everyone hated it. I wish they had such a video to make our world much easier.
thid video is shit..the point to an ac unit is to condition the air not cool it..the cooling is the affect of the conditioning...if tha makes any sense to you at all
It may not be a totally accurate explanation but I'm trying to put it simply since this is Youtube, not NerdsAndGeeksTube. And another thing, fuck Youtube's character limit.
The refrigerant, now in its gaseous state, passes through the suction line and back to the compressor. Then the whole cycle repeats again. It is called a suction line because it has a suction effect that makes the refrigerant pass through it. This suction effect is produced by the pressure differential between the compressed refrigerant after coming out of the compressor and the uncompressed refrigerant in the suction line, the beginning and the end of the loop respectively.
The flow affects the final temperature of the evaporator. The particle theory of matter states that when a matter evaporates, it takes in heat energy from its surrounding (Takes heat from the evaporator in this case.). The particles become more active and spread out, taking up more space. Thus, it becomes a gas. So in the evaporator, the liquid refrigerant evaporates, producing a cooling effect, dropping the temperature of the evaporator.
Thus, it becomes a liquid. The refrigerant in its liquid state then passes through the filter/drier device and then to the capillary tube. The capillary tube as its name states, is a very tiny tube. So the filter/drier is there to remove any foreign particles that may exist in the liquid refrigerant to prevent clogging of the capillary tube. The capillary tube creates a pressure differential to control the flowing of the liquid refrigerant into the evaporator.
Let me try and explain correctly. A compressor compresses a refrigerant, usually R-22 or R-410a. Since the refrigerant is still hot, it can't condense yet. So the refrigerant is passed through a condenser which as its name states, condenses the refrigerant as the refrigerant is cooled below the critical temperature. The particle theory of matter states that when a matter in its gaseous state is cooled, it loses heat energy, thus the particles become less active and take up less space.
Isn't it someting like a refigerator or the freezer...the feeling associated with a very large air conditioner could be most uncomfortable to someone lightly clothed. And what about older people with arthritis, coming in from outside, where it may be 30c to a room where it feels like iike it's 10-15 c, worse when a chill factor is taken into account, cause the big fan is on. Explain to me why it feels so chilly and yet the thermo stll reads 21c? What's the name of this gas being omitted?THX

@MrMrArrtt ,it's not only the compressor,it's the compressor,the condenser(coil + tank) + fan working together what brings the refrigerant (in its gaseous phase) to its condensing point (this part of the system increases the gas pressure by adding molecules and decreases its temperature by removing heat (which passes to the atmosphere (low temperature reservoir). 2EASY MAN !
jorgecalivalle 8 months ago
@jorgecalivalle When you increase pressure, you don't "add molecules." You just reduce the space which those gaseous molecules occupy. The volume of refrigerant in the system is CONSTANT (... unless you have a leak;).
walterbrunswick 7 months ago
@walterbrunswick ,the compressor forces the molecules in the LPS to the high pressure side,the expansion valve lets the liquified gas go from the HPS to the low pressure side thus there's a continuous transfer of mass from P = nRt / V if you wanna increse P you must increase either n or T or/and decrease V.
At any instant mass in the LPS + mass in the HPS = constant ,given there's no leaks

refrigeration has two processes the evaporation & condensation and it is affected by 2 factors the pressure & temp.. the lower the pressure is the lower the boiling point can achieved. it even boils at 0 deg. C to negative something.. instead of 100 deg C for normal H2O. there must be temp difference to obtain heat transfer during cycle. if the air temp has around 35C then the evaporator will absorb the heat which has a temp of about 5C only. so temp diff.. coz air cond means removal of heat

what if i want to heat my house?
can someone explain to me how the air condition can do that?
raynhornzxz 11 months ago
@raynhornzxz Heat pumps have a 3 way reversing valve that can actually reverse the refrigerant flow through the coils, making the inside coil either heat or cool. A very non-complex explanation.
But what i think your asking is how the unit is heating your house. most common from where i'm from is a form of gas-flame heat, which heats air in tubes called Heat exchangers, the blower of your furnace blows air across these tubes to warm the air thats being discharged out your vents.
tvr713 10 months ago
@raynhornzxz Air conditioning is to condition the air, or room temperature, to your desire. The word air conditioning is often used purely for cooling a room, but is also by definition designed to heat a room when desired as well.
Heating is quite simple..... heating elements (rods), much like a clothes dryer... after they heat up a bit (say, 30s), the heater fan will kick on and stay on for approx 30s after the elements have turned off from when the thermostat temp is reached. That's it... lol

The liquid hits the metering device creating a pressure drop turning it into a 25% lliquid 75% gas the change of state allows for heat to be absorbed, 970 btu's worth. The liquid doesn't make the coils cold and the compressor compresses a gas and the heat is released in the condenser where it condenses into a liquid. You need a change of state to absorb heat and a change of state to release heat

i think you might find when the liquid evaporates it absorbs the heat out of the air in the room and releases outside in the condenser. remember...refrigeration is taking the heat out, not putting cold in

What determines the BTU rating for a given unit? I have a new 2 ton unit that is much too big. Which components do I need to replace to bring it down to 1.5 Ton.
brightonmusic 11 months ago
@brightonmusic I'm not 100% certain on this, but I believe it is the combination of all the components that allows a specific AC to have the BTU rating that it does. For instance, how large the compressor is, how large the evaporator and condenser are all significantly influence heat transfer.
What I am certain on though is that a 2 ton unit holds 2 tons of refrigerant.... a SHIT LOAD! Without completely redesigning the thing, I don't think there is any other way to turn it into a 1.5 ton.

correction.. when the freon vapors come out the evaporator coils its a gas the gas is compressed by the compressor then it goes thru the condenser coils losses its heat and condense into a liquid... because the compressor cannot compress a liquid..

This is wrong. What happens is that the cold side of the coils (blue in video) has the potential to remove heat it becomes warm and goes to the red side where it evaporates the heat it removed from the room.
UNIVERSITYHI 1 year ago
@UNIVERSITYHI Yes. To elaborate in better english (sorry, lol), the evaporator fan (the blue side), blows the warm air IN THE ROOM over the cold fins ON THE EVAPORATOR (blue side), and so you feel the cool air from the evaporator, while the EVAPORATOR (blue side) IS ABSORBING THE HEAT from the room.
Because it's a much lower pressure (see metering device), the BOILING POINT IS MUCH LOWER, causing the refrigerant to VAPORIZE (evaporate, per say), which will allow it to go through the compressor.

humpreystrong 1 year ago
@humpreystrong No vapors are designed to leave the confines of the AC system. It is a health and environment hazard when that happens. It should NEVER HAPPEN.
What you are probably talking about is the moving air from the evaporator fan that is blowing cold air out. It is the same air that is in the room, only cold, because it's being blown through the evaporator find, which are cold. Heat transfer.
So NO, nothing in an AC system is pure oxygen... as also, pure oxygen is extremely explosive!

@asdfgoogle hey thanks for answering.. so ur saying that the air we breathe in an air conditioned room is the same air we exhaled (CO2) just recycled to being cold... is it healthy? i mean im always in an air conditioned room... anyway thanks man,, just want to learn ^_^
humpreystrong 9 months ago
@humpreystrong Well... the air you breath isn't entirely oxygen, nor the air you exhale isn't entirely CO2. In fact, nitrogen makes up the overwhelming majority. For a detailed list of what elements make up our air at sea level, just google "What Is the Chemical Composition of Air?"
There is absolutely nothing wrong with it. It's 100% the same air that you would be breathing anywhere else in your house, except it's much colder.
asdfgoogle 9 months ago
@humpreystrong By the way, when you inhale, your body doesn't absorb all the oxygen. What that means is that when you exhale, there is still oxygen in your breath. That is how CPR works. It wouldn't work at all if our bodies absorbed ALL the oxygen. Google the chemical makeup of the air we exhale for more info on that.
Good to hear you're excited to learn though :)

Charles law: pressure increases; temp. increases - Pressure drop, temp. drops
compressors & metering devices change pressure in order to manipulate the boiling point of the refrigerant. In order to change from from liquid to vapor, heat MUST be absorbed, and to go vapor to liquid heat MUST be expelled. Pressure manipulates to boiling point in order to bring about a desire for a change of state.

TechnologyR0xx0rz 1 year ago
The refrigerant, now in its gaseous state, passes through the suction line and back to the compressor. Then the whole cycle repeats again. It is called a suction line because it has a suction effect that makes the refrigerant pass through it. This suction effect is produced by the pressure differential between the compressed refrigerant after coming out of the compressor and the uncompressed refrigerant in the suction line, the beginning and the end of the loop respectively.
TechnologyR0xx0rz 1 year ago
The flow affects the final temperature of the evaporator. The particle theory of matter states that when a matter evaporates, it takes in heat energy from its surrounding (Takes heat from the evaporator in this case.). The particles become more active and spread out, taking up more space. Thus, it becomes a gas. So in the evaporator, the liquid refrigerant evaporates, producing a cooling effect, dropping the temperature of the evaporator.
TechnologyR0xx0rz 1 year ago
Thus, it becomes a liquid. The refrigerant in its liquid state then passes through the filter/drier device and then to the capillary tube. The capillary tube as its name states, is a very tiny tube. So the filter/drier is there to remove any foreign particles that may exist in the liquid refrigerant to prevent clogging of the capillary tube. The capillary tube creates a pressure differential to control the flowing of the liquid refrigerant into the evaporator.
TechnologyR0xx0rz 1 year ago
Let me try and explain correctly. A compressor compresses a refrigerant, usually R-22 or R-410a. Since the refrigerant is still hot, it can't condense yet. So the refrigerant is passed through a condenser which as its name states, condenses the refrigerant as the refrigerant is cooled below the critical temperature. The particle theory of matter states that when a matter in its gaseous state is cooled, it loses heat energy, thus the particles become less active and take up less space.
