Even with an ideal installation of the air conditioner, a certain amount of refrigerant evaporates from the track. It will be necessary to replenish to normal volume. The fact that Freon is not enough, says a weak cooling of the air. Many owners refuel the air conditioner with their own hands.
We fill the air conditioner ourselves
The first step in self-filling the air conditioner is to drain or purge. It is carried out with nitrogen or freon.
Next, it is necessary to check the tightness of the pipelines in order to identify leaks. To do this, the system is charged with an indicator, pressure is pumped up. In the rays of an ultraviolet lamp, the indicator glows in places of leaks.
Now evacuation is carried out - removal of air and possible moisture from the system. An important point is the calculation of the right amount of freon.
DIY refueling methods
For those who want to try refueling the air conditioner themselves, the video will be a very good helper.
There are several ways to self-refuel the air conditioner:
- by pressure;
- by weight;
- using the sight glass.
By pressure
Before you start to charge the air conditioner yourself by pressure, you should study the instructions.
Here the manufacturer gives recommendations on the operating pressure of the system. It is necessary to stock up on the manometric manifold. Through it, a cylinder with freon is connected to the air conditioner. Refrigerant is supplied in small doses. After starting each of them, it is necessary to check the pressure on the manometer. When the pressure matches the recommended in the instructions, refueling the air conditioner is done by hand.
By weight
Those who do not know how to fill the air conditioner with freon themselves should turn to this method. Before refueling, the refrigerant is drained and the route is evacuated. When we refuel the air conditioner ourselves, it is important that all the technology is respected.
The cylinder with freon is weighed on the scales (special) and refuel as much as necessary in the air conditioner. When it is known exactly how much freon is needed, a filling cylinder is used. First, freon is pumped into the cylinder, and from it into the air conditioning system. Video on how to refill the air conditioner yourself, see our website.
With control through sight glass
Before filling the air conditioner with freon itself, it is necessary to carefully consider the state of the refrigerant through the glass. If it has bubbles, refueling is necessary. Fill Freon should until the bubbles disappear.
