Should you use an oil trap on an air conditioner?
An oil trap is a piece of copper pipe that is bent into two U-shapes in a row or two U-shaped opposites and is usually located at the gas line to trap oil to prevent oil (used to lubricate the outdoor unit) following the gas to the rig. cold, avoid reducing heat exchange efficiency and damaging the indoor unit.
People make an oil trap by taking a piece of copper pipe bending the return line (big pipe) installed between the outdoor unit and the indoor unit into a “duck neck” form. Each time the oil is deposited in the “duck neck” will seal the suction line, at this time the compressor will focus all its power and easily absorb the oil. For each height, we will bend one (about 3m, then 1 bend).
The reason for the oil trap is because in some cases where the terrain is not suitable, it is imperative that we install the air conditioner heater higher than the cold unit. At that time, the engine oil is deposited on the pipe and flows into the indoor unit, leading to a condition that reduces the efficiency of heat exchange at the indoor unit. At the same time, this situation reduces the efficiency and life of the indoor unit.
Therefore, when the distance of the outdoor unit is 3m or more higher than the indoor unit, workers will often have to install an oil trap system to limit the oil shortage caused by the cyclone (because it can’t draw oil back).
Trapping the oil in the air conditioner is actually just one step in the whole process of installing the air conditioner, so if you don’t have time to learn the knowledge, then ask the air conditioner repair center.
In addition, due to the pressure of the refrigerant and oil, the oil may be separated from the machine causing oil loss. The compressor will fail if the lubricating oil is low.
As for the small, short pipeline, the oil will return to the compressor for a while and the condensate is also small, but when the distance is long, one must add oil and install an oil separator so that it does not flow far, causing stagnation. Oil on pipelines and equipment increases resistance as well as flowability. Too much oil will change the properties of the pressurizing medium.
