How long should you pull a vacuum on noal change out of a compressor or condensor?
When changing out a compressor or condenser, you should pull a vacuum for at least 30 minutes to an hour, depending on the system's size and the amount of moisture present. The goal is to achieve a vacuum level of 500 microns or lower to effectively remove moisture and air. Using a vacuum gauge can help ensure that the system is adequately evacuated. Always follow manufacturer guidelines for specific requirements.

What is the effect of high vacuum in conderser of power plant?
higher the vaccum in condensor , lesser the steam consumption
Why you have to allow motive fluid and gas to atmosphere while creating vacuum in condenser?
Condensor radiates heat to turn a volume of gas into a liquid. This change in phase from gas to liquid takes up less volume effecting the pressure and once again boiling point of said liquid. Assuming your dealing with HVAC the compressor is dual duty creating vacuum or compressing in a closed / isolated environment. Because of this the compressor must handle a gas and liquid. Think about the point where the condensor has finished radiating heat and the gas has changed phase returning to liquid. To move the liquid back to the evaporator it must be pumped/vacuumed to the other side. The act of pumping or appling a vacuuum to the liquid can change the liquid to gas again and back at certain points inside the compressor (depending mostly on the Temp or PSI). There is a nice solution to this problem since liquid cannot be compressed and everything needs to be lubricated anyway. Oils/lubricants have been developed over the years than can disolve large amounts of refrigerant very little change in volume. This is why you have to allow for motive fluid and gas to atmosphere when vacuum is applied to a condenser. Hope that helps
How do you change the AC Compressor in a 95 Astro van?
Remove the freon from the system. Remove the ac compressor belt and disconnect the lines. Unbolt the compressor, remove it, then bolt the new one in place. Reconnect the lines and belt. Pull a vacuum on the system then refill with freon.
What are the materials used to make a refrigerator today?
The cabinet (outside) is made of aluminum or steel sheet metal. The inside is made of either vacuum formed plastic or steel sheet metal. The insulation is made of fiberglass or polyfoam. The compressor, condensor, coils, and fins ( the inside components) are made of aluminum, coppyer, or alloy. The most common cooling agent is freon.

How do you change the ac compressor on an 1991 Buick Regal?
Remove the freon from the 91 Buick Regal with a reclaim machine. Remove the compressor belts and disconnect the lines. Unbolt and remove the compressor. Bolt in the new compressor, and connect the lines. Put the belt back on. Pull a system wide vacuum, then fill with new freon.

Can you use a compressor to create vacuum?
No, compressors are designed to increase pressure by reducing volume, not create a vacuum by removing air. To create a vacuum, a dedicated vacuum pump is required which operates by removing air from a closed system.
My Mercedes Freon is full the compressor won't turn on?
The compressor won't turn on because there could be aÊproblem with the air conditioning system. You need to vacuum the system.Ê
How do you flush out air conditioning system before installing a new compressor?
You really need the vacuum machine that is used to suck out all the old stuff and moisture etc. to do it right. Reclaim refrigerant. Be sure system is empty. Unhook refrigerant lines from condensor, and evap core. Best to use a "flush gun" and compressed air. Brake clean is a good solvent to use, as it evaporates quickly, and leaves no residue. Flush, and back flush. Use a clean container to capture the solvent as it comes out. Inspect to see if metal flakes are present. Usually one or two flushes in each direction will get all of the grayish, metal flakes out. Usually their is very little, if any in the evap core. On some Fords where compressor failure is catastrohic, and large amounts of metal are deposited in condensor--then maybe necessary to replace condensor. Especially on Rangers, and Explorers. After flush complete. Then be sure and blow compressed air through the evap, and condensor core to remove residual solvent. Be sure and install the correct type, and amount of refrigerent oil in compressor and accumulator. Some techs will put a little oil in the evap & condensor too. My experience has shown that is not necessary. After system is evacutated and charged, check hi-side pressure with manifold gauge assbly to make sure their are no "pressure spikes", this could indicated a faulty condensor core.
