What damage could be done to an AC compressor if there is no refrigerant but you are not using it?
Will using an air conditioner in the winter break it?
Does it ruin an air conditioner when used as a heater?
If you mean using a window AC and installing it backwards so it rejects heat indoors, no and yes, no it does not initially, however as an AC unit has no defrost cycle, eventually the outdoor coil will frost and require defrosting, if this is not done, conceivably liquid refrigerant could enter the compressor and damage it.

Can a car using R12 refrigerant use R134?
Asked in Treaties
Why is using freon forbidden by international treaty?
The damage to the Ozonosphere on earth by the traditional Freon type Refrigerant is becoming more and more severe gradually. In order to protect the Ozonosphere. The signed (Montreal Agreement) by countries has regulated that the Freon Type Refrigerant is the forbidden refrigerant substance. The newly born MTL-1 refrigerant is a refrigerant that complies with the international treaty. This produce is nontoxic, no pollution, no rusty, and is good in oil solubility and refrigeration. It can replace CFC12 and R134a directly without any changes on sealing system, compressor and refrigerant system etc. It will not only avoid the pollution to the air to protect the Ozonosphere but also has an affection of saving energy around 15%.

How to replace the AC compressor on 1992 Saturn?
1. Using an approved refrigerant vacuum system, remove any remaining refrigerant from the AC lines. 2. Place the front end of the vehicle on blocks and remove the passenger side wheel. Remove the mud shield/access panel from the inner fender, then remove the serpentine belt. 3. Physically disconnect the AC lines from the AC compressor, then disconnect the electrical plug and remove the bolts from the AC compressor and physically lift it out. 4. Remove the expansion valve and receiver/dryer, and plan to replace them with a new components. 5. Flush out the refrigerant lines using an approved AC system flush solution. This is necessary since most compressors start to throw pieces of worn compressor into the lines as they wear out. 6. Install a new expansion valve, new receiver/dryer, then install a new or rebuilt AC compressor in reverse order of the above instructions. 5. Use new 'O' rings when connecting the AC lines to the compressor. 6. Using the refrigerant vacuum system again, remove all air and water vapor from the entire AC system and make certain that there are no leaks. Even a small leak will result in a loss of refrigerant. 7. Install refrigerant and approved oil charge as recommended by the manufacturer.

How do you replace a 1995 Ford F-350 air conditioner compressor?
Diesel Engine... Discharge the refrigerant system using a certified recycling/recovery station. Disconnect the 2 refrigerant lines from the compressor. Cap the openings immediately! Loosen the pivot and adjusting bolts. Remove the belt. Disconnect the clutch wire at the connector. Remove the 5 bolts attaching the compressor to the mounting bracket. Remove the compressor. Installation is the reverse of removal. Use new O-rings coated with clean refrigerant oil at all fittings. If a new, replacement compressor is being installed, remove the shipping plates and add 120ml (4 fl. oz.) of clean refrigerant oil through the service ports. Assemble all parts loosely and adjust the belt tension. Tighten all mounting bolts to 32 ft. lbs. (43 Nm). Tighten the compressor manifold bolts to 13-17 ft. lbs. (18-23 Nm). Evacuate, charge and leak test the system......

Why do you charge an air conditioner or heat pump with refrigerant using the low side of the system?
Asked in Definitions
Definition of refrigeration?
The transfer of heat from one space to another. Usually using latent heat evaporation in the evaporator coil, rejecting it in the latent heat of condensation in the condensor coil, using the compressor to pump the refrigerant and the metering device to cause a pressure and therefore temperature drop.
Asked in Technology
What is the principle of air conditioning?
Evaporation is the primary principle. The three primary components of most residential air conditioners are: # Compressor # Condenser # Evaporator As the refrigerant is compressed in the compressor, lowering the temperatures required to change from liquid to gas and gas to liquid. This is an exothermic, or heat generating, process. The compressed refrigerant, still under pressure, passes through the condenser. For residential systems, this is the "fan in a box" part of the air conditioning system outside. The condenser is actually blowing heat away from the refrigerant. Because the refrigerant is pressurized, the temperature is low enough for the refrigerant to turn liquid. The evaporator is where the cooling actually happens. When the pressure is reduced, the refrigerant evaporates; it turns from liquid to gas. Evaporation is an endothermic, or heat absorbing, process. The refrigerant absorbs heat from the air around it. This leaves the air around the evaporator much cooler and ready to be blown into the house. (Most refrigerators operate using the same process.)

How do an 1.5hp air conditioner works?
All refrigerant based air conditioners use a principle called "Heat of vaporization", in which liquids absorb heat when they change state to a vapor. Refrigerant gas is compressed, using the 1.5 hp compressor. When the refrigerant is compressed it becomes hot, so the heated refrigerant is passed through a cooling coil and outside air is blown across the coil to cool the refrigerant to outside temperature. When temperature of the compressed refrigerant drops below a threshold, it changes state to a liquid. The liquid refrigerant is allowed to pass through an "expansion valve". The valve maintains a relatively high temperature on the "compressed" side, then the gas quickly drops to a low pressure. Using "Boyle's Law", we know that as a gas expands, the temperature will drop. The expanded refrigerant cools rapidly and is passed through another coil, which cools the inside air as the air warms the refrigerant. The gas is then compressed again, as described in step 1.

How do you change out a ac compressor on 1995 k1500?
# First, have someone evacuate the refrigerant from the old system. # Physically remove the old compressor, rubber hoses and the receiver/dryer. Also plan to replace the expansion valve, you may need to search for it but it's often at the bottom of the condenser, right where it connects to the hose that leads back to the passenger compartment. # Often the old compressor starts to blow chunks and you end up with debris in the refrigeration lines so you'll want to examine the oil, if it's black or anything but clear, run a "flush" solution through the remaining lines until it comes out clean. Blow it all clean with compressed air that's gone through a dryer. # Reassemble refrigeration system using new hoses, expansion valve and compressor. # Vacuum test the system to check for leaks and to remove any traces of water. # Recharge the system using 134A refrigerant and the approved oil charge either adding the exact amount of refrigerant called for in the specifications, or using a gauge set you can determine when the AC is fully charged.

Asked in Air Conditioning and Coolant
How do you know when you need freon?
The only way to know if Freon (refrigerant) is needed in an air conditioner is to use tools and gauges to measure the performance of the system. The amount of refrigerant needed is based on the design of the entire system including the size of the unit, length and size of the refrigerant lines, temperatures, and type of refrigerant. Refrigerant is not consumed. If refrigerant is needed then the system was either not charged correctly when installed or there is a leak. There could be many reasons a system is not cooling. The correct answer to the question is: A skilled service technician will determined that the system was low on refrigerant by using pressure gauges, thermometers and other tools. There not function a home owner can perform to see if refrigerant is needed.
1996 Geo Tracker refrigerant?
Hi, The refrigerant used has been R-12 in these older vehicles. Today, the refrigerant used is R-134a. Vehicles that are still using the older R-12 should convert to the newer R-134a. There are many places that can convert your car to the newer refrigerant. I had a car done at a local Oil Doctor but most places that advertise air conditioning service can make the change. Hope this helps and is timely for you. Steve H. you can also get a conversion kit at a local parts store like performance parts or advance or any of the chains, it cost me 35 bucks, if your system has not operated in a while you need to get a vaccuum check. if there is a leak in the compressor another 30 bucks can buy some stuff to fix it, if there is a leak in the lines, it may be as simple as a 20 cent o-ring or a new line but the fix stuff for the compressor does not fix lines just compressor leaks.
