How do air conditioning condensers work?
Refrigerant is pumped out of the compressor as a high pressure vapor, and it goes into the condenser inlet as such. The condenser acts as a heat exchanger, transferring heat from the refrigerant to the air which passes over the condenser fins. While in the condenser, the refrigerant will change state from a high pressure vapor to a high pressure liquid, then it moves on to the receiver-drier (on a thermal expansion valve system) or the orifice tube (on a fixed orifice tube system).

An air conditioner is a device which uses a special type of substance which readily changes from its normal gas state to a liquid one (Typically freon or another refrigerant such as R-20 [chloroform] or R-134 [tetrafluoroethane]). The gas is contained in a closed circuit of pipes connected to a pump…. The pump compresses the gas so hard that the pressure is great enough for it to turn into a liquid. In doing this the gas/liquid has got hot (If you try to compress a gas, it will almost always get hot - think of a bike pump when you pump up a tyre (tire), the greater the pressure in the tyre, the hotter the pump gets). Now the hot liquid travels round a set of pipes which allow the heat to escape. Next the liquid under pressure passes through a valve into a pipe where the pressure is much lower, and the liquid evaporates back into its gas state. In doing this it needs to take in heat from its surroundings, thus making the pipes colder. The gas now gets back to the pump and the whole cycle starts again. The pipes are usually arranged so that there are fans to blow air over both the hot part of the pipes and the cold part. The hot part is frequently put outside the house, and the cold part inside. This is called either a 'split pack', or a 'twin pack' depending on which country you are in There are also portable versions which have both parts in the same box, with the cold air blowing out of the front, and the hot air blowing out of a flexible hose which you put put outside the room to allow the hot air to dissipate.

Answer . \nIf this is not a heatpump, the problem is likely a low refrigerant charge. \n. \nHave a service technician check the pressures and also perform a leak search. \n. \nIf they only add refrigerant and do not perform a leak search you are not getting your money's worth.
I have a problem with my ac on my opel astra g because it works only with the cold air and why i turn up the hot air . What can i do ?
Answer . The condensation collects in the lowest part of the HVAC housing. A hard plastic tube penetrates the firewall just to the passenger side of where the steering column exits. On the engine side of the firewall is a short metal tube about 1/2" long to which, hopefully, a rubber tube is a…ffixed.. If you find the rubber tube hanging towards the bottom of the car, blow compressed air into it.. If you cannot find the rubber tube from underneath, it's might be gone! That happened to me. So, from the top of the car, reach down the firewall to the passenger side of the exiting steering column. The condensation exit tube is just a little lower than the steering column, and you have to lift the insulation a little bit. (MORE)

Answer . Make sure it is leaning slightly outwards, so water can drain AWAY from the house.
An air condenser takes in the surrounding air(at about 45-50 degreeCelsius). The vapor at high pressure enters the condenser and accepts the latent heat of condensation from the hot air thereby rejecting heat to condensing coils. The vapor then becomesliquid.
\nOpen circuit breakers. Poor electrical connections to the compressor, thermostat or bad wires not telling relay to cut the compressor on. Elaborate
An electronic humidistat works by measuring capacitance of an air gap capacitor. In this type of sensor, as air flows in between two electrodes, the capacitance between two plates will change according to the RH contained in air.
Same as an air compressor only it is a sealed system filled with freon. When freon is compressed it becomes a liquid, as it expands or turns into a gas it becomes very cold which is why it works well for cooling. The suction side tubing is larger than the high pressure side so the liquid freon i…s constantly changing into a gas in order to fill the space or vacuum, at the same time the gas that has been pressurized becomes quite warm so it needs to be cooled.

Where is the air conditioning condensate drain on a 2000 Plymouth Grand Voyager and how do you clean it?
It is located on the passenger side firewall on the outside directly opposite where you place your feet. It has a wire spring clamp that you can compress to remove it. Clean it and reinstall it, if you do not then air flow will keep the water from draining.
The air conditioner drain condensate tube is located under the hood by the heater core . Remove the tube and clean the adapter, it may have picked up road debris.
It's under the right side dash near the transmission humo. Mine leaked for who knows how long and I had to strip most of the carpet out and dry it for 4 days with fans. The idiots that built the car slipped the drain hose on the plastic pipe but NO CLAMP so my morning rider to work had his big feet …up there and knocked it loose. What a mess. If yours leaked, get it bone dry under that carpet of it will stink and rust the floor pans. Just put a hose clamp on it and that will prevent the big leak. (MORE)

The compressor is a pump. Its job is to raise the pressure of the refrigerant and push it around the system.. The condensor's job is to cool the pressurized refrigerant so it can condense into a liquid. It usually looks like a bunch of tubing with attached aluminum fins, like the radiator on your c…ar.

It can if the drain is stopped up and the evaporator case fills up. It has to go somewhere.
Moisture from the passenger compartment air settling on and draining from the evaporator causes condensed water to leak from the A/C system.. The Condensate (water that collects on the evaporator coil) drips into a pan on the bottom of the A/C unit inside the car. From there it is directed to the o…utside of the car via a rubber hose, and onto the ground. You most likely have a hole in that rubber hose. Check for wear where it goes through the floor or firewall. Or, the pan itself could possibly have a hole in it. Good luck, should be a simple fix.. pintail4 (MORE)
I just need a diagram to see if I've get the bolts back in correctly.
air con compressor compress refrigerant to higher pressure. Ideal case is Isentropic compression which is reversible.
An air conditioning system works in a cycle. One side of the system is considered the high pressure side and the other side is considered the low pressure side. The air condition compressor can be viewed as the center line between these "sides" of the system. Refrigerant R-12 or R-134a (the most com…mon types of refrigerant used in mobile A/C systems) remains at rest in the components an lines of the system until you turn on your A/C. At that point the electromagnetic clutch on the compressor engages and draws refrigerant (in a gas/liquid form) into it to be pumped throughout the system. Upon leaving the compressor the refrigerant has been compressed and thereby heated up resulting in it being transformed into a gaseous state. The refrigerant then travels into the condenser which removes heat from the refrigerant in an effort to return it to a liquid form. From the condenser the refrigerant will often pass through an expansion valve or an orifice (the other component in the system which divides the high an low pressure "sides") where it it "metered" to change it from High pressure on the compressor outlet side to low pressure. After the expansion valve the refrigerant moves into the evaporator. The evaporator is the component that actually removes heat from the air being forced through it by your vehicle's blower fan which pushes "cooled" or "conditioned" air through your vents. From the evaporator, the refrigerant (now mostly in gas form again) travels through a reciever-drier with removes moisture caused by condensation (which may have resulted from the heating and cooling of the refrigerant) before it returns once again to the compressor to repeat the cycle. *Note: . R-12 and R-134A have very low boiling points and can be utilized in a liquid for due to the internal pressure of the A/C system. . R-12 is no longer produced to the CFCs and their environmental impact. . The A/C compressor's electromagnetic clutch is also engaged when using a "defrost" function in most vehicles. . There are high and low pressure sides of the system, the condenser is on the high side and the evaporator is on the low side. Components include: . Compressor . Condenser . Expansion valve/ orifice . Evaporator/ blower motor . Reciever-drier (MORE)
depends on the tonage and make of the unit. estimated any where from 1,500 to 4,000 dollars..
remove front wheels, inner guards and bumper. Then remove air box's, loosen metal bumper support get right air duct out, remove all bolts and fit two longer ones in so it does not drop down. You can now get to condenser pipes and mounting bolts
Basically in a nutshell it takes the air and puts it through a condenser When the air is condensed it gets colder.
did you check whether the fan's magnetic contactor overload device was tripped? if so, simply resetting it might fix your problem. If not, look for the pressure switch of your unit, and push the reset button. sometimes this quick fixes are helpful.
I am going to take the liberty of guessing you mean, How does the air conditioning (A/C) in cars work? CAUTION Do Not try and repair your own A/C system unless you have had special training in A/C repair. A/C systems are under high pressure and can be extremely cold or hot. The air conditioner i…n your car is made up of five major components; the condenser, the compressor, the evaporator dryer, the evaporator, and a thermal switch. When you turn the A/C on you here a loud click form under the hood and hear you engine bog down., that is your compressor turning on. As the name suggests this compresses the refrigerant in the A/C system ( either you have R-12 or R134a). From the compressor the refrigerant is moved to the condenser. The condenser is located in front of the radiator to get the most cooling power. *side note* during the summer when it is hot, if you are using your A/C on a hot day and your car begins to over heat turn off your A/C , the A/C system puts extra heat into the radiator. The condenser turns the gas form of the refrigerant cools it down and turns it into a liquid. It then goes to the thermal switch. The thermal switch controls how much refrigerant to put out to the system and also controls the compressor cycle. At this point the cold refrigerant goes to the evaporator. The evaporator is located in your dash. it is the HVAC (Heating Ventilation and Air Conditioning) box, which is also where the heat comes from. When you have your A/C on the HVAC takes air from the inside of the vehicle and runs it over the evaporator. Since the refrigerant is cold the the cold air molecules switch with the warm air molecules lowering the temperature of the air. During the temperature change the evaporator also attracts moisture and dust, which is why the A/C is always dry air and has a different smell. At this point the refrigerant is very hot and has evaporated into a gas form again. The hot gas then goes to the evaporator dryer. As the name suggests this gets the moisture the refrigerant may have picked up inside the car, moisture damages the compressor. from here the refrigerant goes back to the compressor and the process starts over.

The 2003 Pontiac Montana air conditioning compressor condensationdrain begins on the bottom of the air conditioner compressor. Thedrain goes from the compressor to the bottom of the enginecompartment.
Depending on the year, make and model check the cooling fan/fans and on some models check the fan clutch...........
As refrigerant vapor flows through the tubes, it condenses to liquid and releases heat that the air stream carries away. The condenser is on the high side.
The primary purpose of air filters is to keep the blower and evaporator coil clean. You should clean your A/C filter often to reduce unnecessary energy consumption.

Type your answer here... Well this is not just a problem found on the Stratus. Most cars seem to collect leaves and other dust or dirt in the ventilation system. This debris tends to stay in the compartment that has the condensation drain. This drain can be cleared by poking a pen, little screwdr…iver through from the engine side of the firewall. *note* if you are directly below the drain when the debris is cleared, you are gunna get wet.

If the fan at the furnace is coming on but the outside unit does nothing, check the breaker first. If that's not it check the disconnect switch outside. Some of them have fuses in them that eventually fail. If it's not one of these two things, you in for a service call. I can think of about 15 thing…s that could be the problem. Without the tools and experience to check them you could do some real damage to the A/C or yourself. (MORE)
Take it to a reputable mechanic, there are EPA laws against tampering with an AC unit without a proper license.
AC condensation generally drains from a tube located under the vehicle. When vehicles sit parked and running the AC, a puddle of water will usually form under the vehicle near the drain hose.
Press the power button to turn it on and then lower the temperature or increase it with the buttons.
It comes out through the fire wall just to the left (passengerside) of the transmission bell housing above the catalyticconverter. It is nothing more than a little opening through thefire wall; there isn't any tube or anything attached. Thecondensation box just has an opening out the back of it that… dumpsright outside the vehicle. The easiest way to see it from myexperience is the look in the passenger side wheel well and pullwheel well plastic out of the way. Any way you look for it, it isjust a small black hole coming out of the fire wall and VERY hardto get to. The seal around it can go bad which can cause water tobuild up in the passenger side floorboard and the drain doesn'textend far enough out so the condensation drops straight down andwill build up behind the fire wall and dump out about half way downthe vehicle between the front and passenger doors.

What negative effect will too low a condensing temperature have on the operation of an air conditioning system?
Low condensing temperatures may result in compressor operational issues and can even lead to failure. Minimum condensing temperatures are generally established by compressor manufacturers in order to ensure that proper reed valve operation and proper sealing of these valves will take place. Addit…ionally, the capacity of the metering device upstream the evaporator is partially dependent on the pressure difference across it. If the pressure difference is too low then the evaporator will be starved. Over feeding the evaporator resulting in floodback to the compressor and damaging it. Either quickly due to the compression of hydraulics or more slowly by lubrication loss from oil diluted with liquid refrigerant. (MORE)
It forms because the air around the grills get so cold that they hit what is called the Dew point for the air. The Dew point is the Temp. at which the water in the air will form on surfaces.
The condensation drain is plugged. We don't know what vehicle you have so we can't tell you where the drain is located.
Yes. The condenser is on the high side, and high pressure vapor goes from the compressor outlet directly to the condenser inlet.
It passes heat out of the high pressure high temp vaporized refrigerant so the it becomes a high pressure lower temperature liquid. It passes heat out of the high pressure high temp vaporized refrigerant so the it becomes a high pressure lower temperature liquid.
Air conditioning is refrigeration: the removal of heat from the air. Almost all forms use evaporation, the process by which a liquid turns to a gas and in the process absorbs heat energy. Two of the major forms of cooling are: Evaporative Cooling Water is allowed to evaporate on a surface, absor…bing heat. This is used in "swamp coolers" and in commercial "chillers" that work with mechanical refrigeration. Mechanical Refrigeration A liquid refrigerant (generically called freon ) is circulated through a chamber where it is allowed to expand. This expansion causes liquid to evaporate into gas as the molecules absorb heat. The gas is then mechanically compressed to a liquid again, where it loses its heat outside the system. (Household refrigerators transfer this heat through coils to the kitchen air, while window and central air conditioners release their heat outdoors.) --- Thermoelectric Cooling Small portable coolers can also use electrically-driven coolers that create a heat flux to withdraw energy as electric current, albeit inefficiently.

A cool ,low pressure vapor is pulled into the compressor fromthe evaporator coil, it will be approximately 70 psi and 40Fdegrees, if using R 22 refrigerant. . As it may be 100F or more outdoors, the compressor must bump upthe cool low pressure vapor up to a hot high pressure vapor, itwill pump it up to about 30F degrees above the outdoor ambienttemperature, this is so that regardless of how hot it may get outside, the refrigerant is hotter, thus able to reject heat to therelatively cooler out door air, thus condensing the vaporrefrigerant into a liquid refrigerant that is still hot but a highpressure liquid. . The hot high pressure liquid is sub cooled to about 15F degreesbelow the condensing temperature . That will be about 125 F @ 270 psi, again if using R 22refrigerant. . The hot high pressure liquid refrigerant is then sent to themetering device, this is what delineates the hot high pressure sidefrom the cold low pressure side. .

Pretty simple, it condenses the refridgerant into a liquid (giving off energy as heat) the cooling happens later in the evaporator part where the liquid turns back into a gas (taking the energy from surrounding area, thus lowering the temperature.)

Generally, no. Condensation is water condensed from the air onto the cooling coils. The condensate water is essentially pure when it drips into the drip pan. However, if the condensate is allowed to sit stagnant for a while, it can grow mold or bacteria, which _can_ be hazardous.
If you want a full, in-depth answer explaining the variouscomponents, how pressure switches work, various compressor types,etc., I'd recommend you take either some HVAC courses or anautomotive air conditioning course.. your local community collegemight offer them, plus they can give you what you nee…d to take thetests and get certified to where you can buy the 30 lb. cylinders,rather than those dinky little 12 oz. cans... what I'm going togive you is a very basic nickel tour. The compressor pushes the refrigerant through the system. At thesame time, heat and humidity is drawn out of the compartment beingcooled.. could be the passenger compartment of a car or piece ofmachinery, could be a room in a building, could be the inside of arefrigerator... it all works the same way. When the refrigerantreaches the evaporator, that heat from the compartment being cooledis drawn to the refrigerant, as heat flows to a colder object. Therefrigerant absorbs that heat, then gets cycled back to thecompressor. It becomes pressurized, undergoes a superheat, thenundergoes an extremely rapid cooling cycle when it gets to thecondenser, and that superheated refrigerant transfers its heat tothe much cooler ambient air flowing through the condenser fins.Then the now much cooler refrigerant cycles back through to theevaporator, and a fan blows across it, delivering cool air throughthe HVAC system.
