How can you remove an aircondition compressor without losing the refrigerant?
Before removing the compressor from a refrigerator or other appliances, you must 'reclaim' the refrigerant. This is done by connecting a compressor-pump on the access connection and pumping the refrigerant into an approved storage tank. once the refrigerant is out of the system, you crimp & cut the lines going into the compressor. There will be compressor lube in the compressor; don't spill it or let it leak out.
How does the failure of the compressor in a refrigerator affect the heat transfer cycle?
When the compressor fails, the high vapor pressure refrigerant is no longer condensed. Without a phase change of the refrigerant is refrigerator will not cool.
Is freon required for the compressor to run on a 2004 Chrysler Sebring?
Yes, the system will not function without sufficient refrigerant.
Why does hot air blow out of the vents on the passenger side of a 2003 Dodge Grand Caravan when the air conditioner is on?
The air conditioner has failed in some way. Either the compressor has failed or the pressurized refrigerant has leaked out. DO NOT operate the air conditioning until the problem has been fixed, the refrigerant contains oil to lubricate the compressor, which, if the refrigerant has escaped, will be damaged without lubrication. Don't turn a cheap fix (refrigerant recharge) into a very expensive one (replace compressor).
How do you engage the AC clutch to refill the system?
You don't need to engage the compressor clutch to recharge the system. In fact, you shouldn't engage it without refrigerant and oil in it, because the refrigerant carries the compressor oil in order to lubricate the compressor. But, to answer your question, you disconnect the low pressure switch, and run a jumper wire between the two female ends of the connector.
I installed a new AC compressor. I do not have freon in the new compressor and it is not hooked up. My question is... will it hurt the vehicle if I drive with out hooking up the AC?
No harm will come from driving it. You just don't want to use the AC system without any refrigerant in it - that could harm the compressor. The refrigerant also cycles the compressor oil, so running the compressor without the refrigerant in it is detrimental in this regard. Also, since you had to open up your AC system to replace the compressor, you should have also replaced either the receiver-drier or the accumulator (your vehicle will be equipped with one or the other, depending on whether you have a Thermal Expansion Valve system or Fixed Orifice Tube system - it'll never have both), as they contain a desiccant which will become fully saturated within five minutes of exposure to atmospheric air. The desiccant in these components is vital to the proper operation of the AC system.
How do you get ac to blow cold compressor not kicking in?
Find out the reason the compressor isn't engaging, of course! It could be a problem with the clutch, a problem with the low pressure switch, a low refrigerant level (likely caused by a leak in the system which needs to be repaired), or the compressor itself could be defective. Without any sort of diagnosis, we have no way of narrowing down the causes. You won't get cold air without the compressor, so that has to be dealt with.
How is work quench valve in reefer?
A refrigeration circuit is provided with a quench line connecting the liquid line and the suction line and containing a QEV. The QEV is controlled responsive to the superheat of the refrigerant supplied to the compressor. By injecting liquid refrigerant downstream of the suction modulation valve and the sensor for the TXV, the system can be operated at low capacity without overheating the compressor oil.
How do you change an ac compressor on a 99 Mazda 626?
Legally you can't without the EPA's Secton 609 certifacation, because any refrigerant in the system must be removed by a licensed technician. And even if its empty of refrigerant, after you relace the compressor you must pull a vacuum on the system to remove air and moisture. I would recomend taking it to a garage. The guy above probably owns an AC garage. You need to have a certified mechanic "discharge" and "re-charge" the refrigerant. However, the act of replacing the AC compressor can be done by you (although this depends on "you"). My local shop charges $85 to remove the refrigerant and replace it again after I have changed out the compressor. Tomorrow I will take the old compressor off and put the new one in...from what I gather so far...this entails removing the plastic cover below the compressor, remove the belt, remove the compressor, replace the new one and use a wrench on the belt "auto-tensioner" to get the belt back on. Run the car and make sure it works properly...then take it back to the garage, get the refrigerant re-charged and you should be good to go!
If you have checked the wires the fuse under the dash and the large relay on the firewall but your 1992 C2500 still has no power to the AC compressor what else can you try?
is likely out of freon,pressure switch in accumulator will not allow compressor to start without refrigerant charge- have system serviced and recharged
What conditions allow for a system to be opened and repaired without recovering the refrigerant to the required vacuum level?
none I was asked this question on the type 2 epa practice test and none wasn't an option so it cant be none.
If my Condenser fan didn't work for a day could that ruin my air conditioner?
Yes it would cause your compressor needs that fan to cool down the refrigerant going through your condensing coils.. Without that fan it would cause high head pressure and damage the compressor as well..
