Air conditioners are refueled by service departments. But some owners would like to master this procedure on their own. First you need to acquire all the necessary tools.
Air conditioner refueling tools and equipment
- refrigerant cylinder;
- electronic scales for freon;
- pressure gauge with fittings and shut-off valve;
- vacuum pump for filling air conditioners;
- screwdrivers;
- adjustable wrench;
- inspection mirror;
- a puncture for a disposable balloon;
- valve adapter for the nipple;
- refrigerant cylinder shut-off valve;
- filling cylinder;
- hoses for filling air conditioners with union nuts;
- thermometer.
Air conditioner filling cylinders
When buying a cylinder for charging an air conditioner, you should pay special attention to the type of refrigerant.
It is indicated in the instructions. Air conditioner filling cylinders contain 10 kg or more of refrigerant. But for one refueling, it is quite enough to purchase a small disposable bottle for 300 - 400 grams.
To use a disposable balloon, you will have to buy a balloon piercer separately. It is not expensive at all.
A shut-off valve is attached to reusable cylinders.
Air conditioner filling pump
The vacuum pump for charging the air conditioner is used at the stage of preparing the pipeline for starting the refrigerant. The pump cleans the system from freon residues, moisture and mechanical debris.
To work with household air conditioners, a vacuum pump with a capacity of up to 50 liters per minute will be sufficient. The weight of such a pump for filling air conditioners is about 10 kilograms.
Pressure gauges for filling air conditioners
It is most convenient to use the pressure gauge built into the manifold for filling the air conditioner. Ready-made collectors of various companies are sold in many by specialized centers. To save money, you can purchase a separate pressure gauge, and a separate manifold for it. Thus, the optimal options for the job are selected.
Scales for filling air conditioners
Only electronic scales are used for filling air conditioners. They are very easy to carry as they are built into a small plastic case. The maximum load of the scales for filling the air conditioners is 100 kg. But more is not required.
Air Conditioner Filling Hoses
To refuel a household and semi-industrial air conditioner, you need to purchase two hoses. They are made using a special technology, as they must withstand high pressure. On both sides, the hoses end with external nuts. The standard length is 0.9 meters. Air conditioner charging hoses can be purchased complete with manifold or separately.
