@lordparoose48 I meant that explaining the atoms and physics behind how it works does not change how fast I can simply understand it. Just listen for 5 minutes and you basically learned it.
Based on 2nd law of thermodynamics Refrigerator and AC works on same principle. It consists of two main things 1 . Source 2 . Sink Refrigerator removes the heat from the inside area(source), and reject it the surrounding ( sink) Here sink is high temp zone And source is low temp zone And refrigerator does work on the system And one more factor is its coefficient of performance which is equal to heat rejected from source divided by difference of heat of sink and source . It works opposite of heat engines . Hope u like it❤
That's basically what a heat pump is: a reverse AC. The refrigerant is pumped in reverse so that the cold part is on the opposite side, and cold air is pulled in to make it warmer
It's very accurate but the most important part is left out. It's that the phase change of the refrigerant is what traps or releases heat, and its the reason AC unit can pull heat from very cold air.
That’s too much for a simplified video like this. Most people won’t understand how the refrigerant is boiling at a lower temperature in the evaporator. The ac cycle is actually an amazing thing that gets overlooked in everyday life.
@@anandr1385He doesn't have to get into the science iof it tbf, he just needs to mention that there's something happening between inside and outside that makes heat exchange possible
@@nickt6980 There's no need for phase change diags. But it's extremely relevant information that due to the refrigerant properties, the ambient air makes the refrigerant boil and loses it's thermal energy in the process. And when refrigerant condenses it gives out the same thermal energy back. And this is the main reason how the AC unit can take heat and move it elsewhere.
@OMGrealVid for the sake of the video, the phase change diagram is a useful educational tool. If you're gonna do calculations, all you need is the tables.
the hot air being pushed outside was such a blessing at my secondary school, everyone would take turns sitting around it and absorbing the heat when it was cold outside, the staff never liked it too much but i dont remember them ever actually making it off limits
Engineering student here! It's actually pretty simple: 1) Compress the refrigerant, making it a hot gas. 2) Let it cool until it's the same temp as before (which turns it into a liquid). This heat goes outdoors. 3) Let it expand, cooling it down below the room's temp; this is where the coldness comes from. 4) The room's heat enters the cold refrigerant, cooling the room. The refrigerant also turns into a gas. 5) Repeat The phase changes between liquid and gas make the refrigerant extra effective at cooling, which is why refrigerants have low boiling points. Fun fact: without AC, semiconductor factories wouldn't exist, so neither would phones or computers
Bro earlier then hot air was inside house now it's outside,in short it's still in same ecosystem either inside house or outside so that doesn't affect global warming.CFCs released from cooling unit is what makes ozone damage
FR i didnt know the ac blows the warm air back out i just thought the coolent would change the temp, not the ac sucking the warm in and blowing literally outaide! extremely fascinating
@@ENDER_ELSA_1817what else did you think would happen? The energy added to the refrigerant doesn’t just disappear out of thin air. If it worked the way you originally thought, the refrigerant would heat up and that would be the end of it. Also, this explanation was slightly over simplified, even for a simple explanation. The refrigerant gets heat added to it by its vaporizing and released via its condensing. Non phase change heat transfer (convection) is insufficient to transfer the heat needed. Additionally, this is what makes refrigerants such potent greenhouse gases, ability to store and release lots of energy.
That’s what a heat pump does, it has a revering valve that reverses the refrigeration cycle. Depending on if you want cooling or heating. No gas connection needed
@@ImTheGuy-mt1lw I'm guessing it's the same concept. Bc I can have my ac on sucking in cold air and it produces colder air. And the process generates the heat. Not the actual hot air.
This is a great simplification for non-engineers. The minute you start explaining RC-134a vapor domes and actual component names, people would begin to think that they're scientists or something.
I recently put window units in my room and my daughter's room. Keeps the rooms cool and keeps the electric bill a lot lower than if we were trying to cool the entire house at night
I don’t think AC is the way tho. World is getting hotter and energy will eventually be too expensive to rely on AC. Making well designed buildings that naturally self regulate temperature, painting reflective surfaces and better use of shades will be much more reliable in the long run
@@solk.posner7201yeah good luck with that buddy ac is like one of the least polluting things on the planet compared to fossil fuels when it’s a 100 outside you 100% need it
@@solk.posner7201 Doesn't hurt to do both. Most of the time, passive cooling will do the trick, but on those days when it's 100+, you're gonna want the artificial means to cool the inside. Also invest in good building practices and insulation.
*I knew that from Rimworld.* I found out the hard way that the hot air needs to be outside, and not inside, when I saw the temperature 100°C and gojng up...
True, but I think it's more easy to say that the process of cooling is kinda like a boiling thing, cold air falls down because it's more dense and hot air goes up and repeat
Moral of the story: Reverse the AC to prevent global warming and keep checking the temperature after every few hours to make sure the ice age doesn't start.
Ac heat contributes next to nothing to global warming, but are also a net producer of heat. They don't cool air, they cool some air and heat other air equally, while also producing heat from it's operation.
Stick with it. You'll never stop learning. Wait until you start studying up on manual J manual D and relative humidity. When you are ready for it. It's a lot but it's fun learning it.
HVAC units don’t actually really just add cool air to your house. They take the heat out of the air and then blow it back through your house. So when you turn on your thermostat, all your doing is starting this cycle
The refrigerant absorbs the thermal energy from the air, and the cold coil condenses water vapor in the air, thus dehumidifying at the same time. The heat absorbed into the refrigerant is then rejected outside and cycles back around to absorb more heat. It is able to do this by manipulating the pressures of the refrigerant for a desired effect. The low pressure causes the refrigerant to turn to a vapor, and that process absorbs heat for the phase change. It then passes through a compressor to increase the pressure, which increases its boiling point. The vapor refrigerant turns into a liquid and rejects heat during this phase change. After rejecting heat, it passes through a metering device (a small orifice) that creates a pressure drop decreasing the boiling temperature. I do HVAC and I love this stuff lol
The refrigerant transforms from liquid to gas, which is just boiling, that requires energy. The energy is supplied by the room air that is hotter than the boiling point of the refrigerant. This energy movement is what we perceive as temperature change.
Air conditioners work by taking warm air from inside a room and sending it outside. They use a coolant liquid that absorbs the heat and cools the air inside. The cooled air is then pumped back into the room, keeping it at a comfortable temperature. This process repeats continuously to maintain a cool environment.
Here's one very important part. That coolant has a property that makes it gain heat when it gets compressed and lose heat when it decompresses. When it is in the cooling part it is decompressed and a compresses to get hotter so when it's outside it is cooling off much faster than if the temperature of the coolant was the same as it was blowing into the house

Based on 2nd law of thermodynamics
Refrigerator and AC works on same principle.
It consists of two main things
1 . Source
2 . Sink
Refrigerator removes the heat from the inside area(source), and reject it the surrounding ( sink)
Here sink is high temp zone
And source is low temp zone
And refrigerator does work on the system
And one more factor is its coefficient of performance which is equal to heat rejected from source divided by difference of heat of sink and source .
It works opposite of heat engines .
