1
Filling by weight. With the help of special scales you weigh the cylinder, check the amount of refrigerant needed volume to fill with gas. This method is very simple and does not require much space for installation, but first you evacuate the refrigerant and vacuumsale circuit. If you know the amount of refrigerant, then use the filling cylinder. To do this, attach the balloon to the cylinder, fill to the desired volume, and then from it fill the whole system. This gas station provides high accuracy and speed of operation, but the cylinder capacity is relatively small – only 2-4 kg.
2
The filling pressure. Here is a need for accurate tabular data of the manufacturer. With the help of the gauge manifold to the system, connect the cylinder with the refrigerant and the small portions are filling. After each refueling, check the gauge with the table, do it as long as the readings do not match the data of the manufacturer.
3
Gas station airand can be carried out with the help of the sight glass. You periodically observe the state of the refrigerant. If you see a constant stream of bubbles then it means that it is necessary to charge the system. Fill with air until complete disappearance of bubbles and the establishment of a uniform fluid flow. Do this in batches, each time to achieve pressure stabilization.Each of the described methods has its pros and cons, and the choice on the specific refueling air conditioningand depends on many factors. But in any case, if you need such services, contact the professionals who have not only knowledge but also special tools. Only in this case, the technique will serve you long and will be an indispensable tool.
