Air conditioning not cool to add refrigerant can line?
These aspects to check?
< p> just entered a few days of may, the weather in Beijing began to directly kill in summer.
Silent for a whole winter again of the air conditioning to requisition, the elderly old car will start burst into all sorts of problems, air conditioning don't know what the reason is not cold.
Now open air conditioning, transferred to the lowest temperature, measured the temperature of the outlet is only 10.
About 2 degrees.
It's for the hot summer months, basically equals no refrigeration.
< / p> < p> < / p> < p> air conditioning system is not complicated, refrigerant and heat can cause bad air conditioning.
But the measured data of air conditioning refrigerant pressure is large enough, refrigerant is not missing, radiator also brute-force net, the cooling effect is good.
Since the two main problems, plus the car of eight years old, air conditioning internal piping must is too dirty to lead to poor cooling effect.
< / p> < p> < / p> < p> traditional methods need to break down of the demolition of the pipeline are thoroughly to clean, this is very time consuming and physical strength, and some old car fragile line is very fragile, this time really is a static.
This device can be connected to the air conditioning system of high and low pressure pipeline, do cleaning cycles.
Its cleaning process is a little complicated because the air conditioning internal line remains refrigerants, so also involves the problem of recycling.
Cleaning process can not start the engine, on pump circulation inside the equipment for washing line.
Liquid everything (
Itself, though not refrigerants, but at the moment also have the effect of cleaning, use of refrigerant itself will bring out pipeline internal residue.
< / p> < p> < / p> < p> < / p> < p> < / p> < p> before you start, row boats inside is clean, no dirty dirt.
In the following work, the platoon oil will collect dirt from the air conditioning internal piping, scene will definitely surprised your eye.
Only in half an hour later, the platoon oil bottle is full of dark stain.
The dark thing is nothing but comes from the air conditioning compressor itself wear of the metal powder and frozen oil aging.
Air conditioning compressor with the engine is actually the same, the same is run by the piston, the same will develop blemishes, so is the need to maintain.
