[@anatolesokol]

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.

[@etherealvox2010]

To understand how an AC works , one needs to understand the thermodynamic phenomena that occur : 1.Heat travels from HOT to COLD naturally. 2.Boiling point of a liquid depends on both temperature and surrounding pressure. Water boils at 100 degr C / 1 bar atm pressure. If you lower the atm pressure below 1 bar, it will boil at less than 100 degr C. 3.When a liquid ABSORBS heat it EVAPORATES. When vapor releases heat, it CONDENSES 4.If a liquid is compressed, the pressure increases, temperature increases while volume decreases. So , when the refrigerant (liquid+vapor) gets into the evaporator (inside the house ) , it absorbs the heat from that room , hence , it evaporates . Now, in order for condensation to occur in the Condenser(outside the house), the now vapor refrigerant(hot) needs to be hotter than the outside air so that to give away the heat (see point 1 and 3 from above) and condense (become liquid again). For this to happen, the compressor compresses the vapor refrigerant thus increasing its temperature (see point 4 ) . When the compressed vapor refrigerant enters the condenser , it releases some of the heat into the surrounding air which has a lower temperature ( see point 1 ), and transforming into a liquid ( condensation ) . The liquid now passes through an expansion valve ,where its pressure is reduced and the liquid begins to boil (SOME vapors form) thus releasing some of its energy (heat) becoming even colder.Now we have a mix of cold liquid+vapor ready to repeat the cycle .

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.

In HVAC School and this video helped a lot. Basically your AC doesn't make cold air. It simply transports the "hot" air inside the living space to the outside space by using refrigerant as a medium. 1. Compressor inlet receives GASEOUS REFRIGERANT(Refrigerant now hot and under pressure) & Pumps it into the condenser coils. 2. In the condenser coils refrigerant is now liquid. And heat starts to leave (Gas gives off heat when changed from gas to liquid). This giving off of heat is expedited by a fan or blower at the condenser coils. 3. The refrigerant goes through a metering device like an orifice and becomes low pressure again as it enters the evaporator. 4. At the evaporator coils, another state change happens to the refrigerant, going from liquid back to gas (liquid absorbs heat when it changes from liquid to gas). The gas refrigerant is whats absorbing the heat in your home and condenser expels it outside. Your AC does not create cold air, its basically a system that transports heat. 5. The gaseous refrigerant then enters the compressor again where it starts the cycle all over, constantly just removing heat energy from your home. WOW, HVAC School is paying off so far. This stumped me before. Cant wait to graduate and get out there in the field. 40K in student loan debt from college, didt even graduate, now I'm going to trade school to learn skill to make some good money. I shoulda done this straight out of high school. Oh well.

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.

[@WahajKhan017]

Compression: The cycle starts when the compressor compresses the refrigerant gas, raising its pressure and temperature. Condensation: The high-pressure, high-temperature refrigerant gas then flows to the condenser coils located outside the building. As outdoor air blows over these coils, it helps to cool down the refrigerant, causing it to condense into a high-pressure liquid. This process releases heat from the refrigerant into the outdoor air. Expansion: The high-pressure liquid refrigerant now moves through the expansion valve, which restricts its flow and causes a sudden drop in pressure. As the refrigerant passes through this valve, it expands rapidly, becoming a low-pressure, cool liquid. This cooling process prepares the refrigerant to absorb heat from the indoor air. Evaporation: The cool liquid refrigerant then enters the evaporator coils inside the building. Indoor air is blown over these coils by a fan, causing the refrigerant to evaporate into a low-pressure gas. As the refrigerant evaporates, it absorbs heat from the indoor air, cooling it down in the process. The now-warm refrigerant gas is then drawn back into the compressor to start the cycle again. Thank me later :)

[@Troughi]

I build a few of these every day at work. Our “conditioners” actually dry the air with these same principles and a few more. Instead of an “inside coil” we use heat exchangers with drains to extract the water. And we use a danfoss condensing unit in every one of out dryers.

I am at Monroe Community College in the HVAC degree right now. In the most plain terms, it is all about moving heat from one place to another like in a refrigerator taking the unwanted heat from either the door being open, hot food stuck in, or any heat that finds a way in and extracting it to another place probably being your kitchen. If you want to know more about how pressure and temperature correlate look up Charle's Law and Boyle's Law. Compressors don't die, they are murdered usually. Unlike gas, liquid can't compress (think of a belly flop into a pool and how the water feels like a solid). The vapor increasing in temperature is called superheat which is a sensible type of heat (can be measured with with thermometer) where the change in state between liquid/gas in the condenser and evaporator is latent heat (phase change). On the contrary, cooling the liquid is subcooling. TXVs are not the simple type of expansion valve (also called metering device), the simple ones are capillary tubes. Where TXVs have a temperature sensor between the evaporator and compressor (discharge line) to regulate superheating to a specified range, a capillary in plain is sight is just a looping coil with no way to control the amount of liquid getting through. The TXV regulates, where the capillary tube just merely keeps pissing refrigerant.

[@alwaysthebest4536]

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.

I understood its so difficult to understand this. So i passed it on to my dad!

[@SuperGuruoo7]

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.

[@ambidekstrusful]

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.

[@naleensilva7265]

@@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.

[@abhinavg3514]

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 😁

[@sealteam818cw]

"Condenser fan makes it easier" to remove heat from condenser coil. Actually, if you didn't have a fan or it fails, your Conpressor will OVER HEAT AND GO OFF ON THERMO. So, it is necessary to the function, not just an "Aid". Also a Blower fan for your indoor evaporator, or your coil will end up frozen solid.

[@arabcampers9554]

So basically i can turn any refrigerator to air conditioning unit with small modification .

[@MichaelThe-Pyro]

No, you can't. refrigerators have at best a 50% duty cycle that means it can only run 5 minutes out of 10 before it has to shut off. an AC unit has a 100% duty cycle meaning it can run continuously without damage.

[@arabcampers9554]

Michael The-Pyro that why i said small modifications required my friend

[@thespectre2012]

Yes!

[@baybum7]

@@arabcampers9554 if your room is as small as a refrigerator, then yes. The compressor and design is for a small 2-3cu m capacity, compared to a window or split type airconditioner that's designed for room/s. You can try, but it would be highly inefficient and you'll almost never reach the coollness desired.
