I have a vehicle that is not currently running from which I am pulling the engine. I thought I could use this not just to put a vacuum on the system later when I swap to a different vehicle, but to evacuate the Ra refrigerant currently in the system. However, the instructions for the vacuum pump say not to run it on a pressurized system. So what do I do?

I can't take the car to a mechanic to have them properly pull out the refrigerant to a recovery system because the car is not mobile. I know you're not supposed to just dump Ra to atmosphere though it's not as bad as R Can I run the vacuum pump on the system anyway? Is that effectively the same as dumping it to atmosphere? Where do I go from here? They are designed to be disconnected from the engine and put to the side so you don't have to discharge the refrigerant from it. If you absolutely believe you need to remove or discharge the system, take it to a shop which can draw out the ra from the system in an environmentally safe way.

You should be able to work out some kind of deal with them to bring the vehicle back to them for recharge after it's done. Remember, though, you will have to replace the dryer when you put it back together, as well as recharge the ra. Using the vacuum pump to remove the ra will do the same thing as just dumping it directly into the atmosphere. If you cannot move the vehicle and only want to dump it, you really need to be careful of the ra freeze burning you as it decompressed out of the system.

Obviously, I don't recommend this approach if at all possible. There's absolutely no need to use a vacuum pump to remove the refrigerant. It's really easy to remove the refrigerant by condensing it out. Attach the low side blue hose and coupler to the manifold, as well as the yellow service hose to the tank, and black vacuum hose to the pump. Open the tank valve. Close the LOW Ra coupler. Evacuate the system - i. When done, close the VAC valve, disconnect the pump and black hose from the manifold.

At this point the tank, the manifold, the yellow service and blue low side hoses are evacuated. Locate a chest freezer near to the car e. Put the tank inside the chest freezer. Let it freeze overnight. Close the LOW valve. Attach the LOW-side coupler to the car. Open the coupler. Slowly open the LOW valve - ensure that the pressure doesn't exceed the expected Ra pressure at ambient temperature psi at most.

This drains the refrigerant into the tank via the low-side port. The refrigerant will be condensing in the tank. At 0F typical freezer temperature , the remaining pressure will be around 6PSI. Put the tank in a plastic bucket, fill with dry ice. Put back into the freezer as this slows down the sublimation. You've now lowered the tank's vapor phase pressure to well below 22"Hg.

When done, assuming that there was no air in the car's system, the pressure should be still below zero as almost all of the refrigerant vapor will be condensed in the tank, with very little left. You should strive for vapor pressure of 20"Hg vacuum or less. Home Questions Tags Users Unanswered. Ask Question. DucatiKiller 30k 17 John John 18 1 1 3.

It is important to vacuum an air-conditioning system to remove any air or moisture that may damage the system in the long run. Moisture in the AC system is a serious problem, because moisture reduces the performance of the AC system and condensation of water can cause the AC system to freeze.

Florida ASE Master Tech explains what automotive AC vacuum pumps are used for and answers frequently asked questions regarding their practical use when servicing car air conditioning. Understanding the theory of how a car air conditioning system works is very helpful when diagnosing problems beyond an obvious leak; hands on experience is priceless when applying theory to real car repair situations. One very helpful and necessary tool when doing AC work is a vacuum pump.

The following process removes damage causing moisture once the system has been opened up to be inspected or after a repair as been performed.

Get the kit! Proper evacuation after initial installation or after service where the system has been opened to atmosphere is critical to proper operation of an air conditioning system. Evacuation is a two step process of degassing and dehydration. Degassing removes non condensibles which cause increased head pressures and increased operating cost. Where high temperatures are frequent, non condensibles combined with moisture will also cause oil failure, decreased capacity and increased compressor wear and potential failure. Losses associated with improper evacuation can be very high. Moisture is the second issue. Because POE breaks down into its fundamental components, it can clog the metering device and contaminate line sets. This could result in the need for complete system replacement. Moisture refrigerant and mineral oils form acids that will cause system failure due to copper plating and damage to compressor windings.

A common question has been; What year did the car manufacturers start using A? The answer is

In the evaporator, that liquid refrigerant flashes boils back into a vapor because it is absorbing heat from your passenger compartment. Examples of faults that are commonly seen in AC condensers include external damage to fins or tubes, pinhole leaks, and clogged passages. This article will briefly cover the procedure required to replace a typical AC condenser. Step 1:

Pulling a vacuum is a common part of air conditioning repairs. Vacuums are used to evacuate ACs, a process by which they pull out all air and moisture from the refrigerant system prior to testing, repairs, and recharging. Generally, this is best done by an HVAC professional. If you are looking to do simple at-home repairs, though, learning to use a vacuum pump could be very helpful.

В XVI11 веке некий английский купец приобрел у севильской церкви три десятка бушелей апельсинов и, привезя их в Лондон, обнаружил, что фрукты горькие и несъедобные. Он попытался сделать из апельсиновой кожуры джем, но чтобы можно было взять его в рот, в него пришлось добавить огромное количество сахара. Так появился апельсиновый мармелад. Халохот пробирался между деревьями с пистолетом в руке.

Деревья были очень старыми, с высокими голыми стволами. Даже до нижних веток было не достать, а за неширокими стволами невозможно спрятаться. Халохот быстро убедился, что сад пуст, и поднял глаза вверх, на Гиральду.
