Big.
the big line is the suction for the the compressor in the A/C unit, The small line is the compressor discharge that goes to the furnace
The suction line will be the larger line going into the compressor.
Yes. They are.
The suction line is the big one. This line should be cold when the unit is on. The small line is the liquid line.
A suction line filter is added to the system for a different purpose than the liquid line dryer. A suction line filter is added:A : to keep acidic oil in the system from working its way back into the new compressor.B because the suction makes the acid removal better.C because the suction line is cold and full of acid.D all of the above.
You always use the largest a/c line to re-charge the system..It is the "suction side" The small line is the high pressure line.
air contains moisture & suction line is very cold both in contact moisture turns into ice. just a joke
The system will not cool if it is low on refrigerant. Check the suction line and see if it feels cold and is sweating. The suction line is the larger of the 2 and is covered in black insulation. If it is not sweating or if it is warm to the touch, you are probably low on refrigerant. If you have to have refrigerant added more than once, it's a sure bet there is a leak in the system.j3h.
A suction line is usually cold to the touch.
No, the liquid (discharge) line is the high pressure side. The suction line is the low pressure side.
The larger line is suction. The larger line is the suction side which should be on the right side of the compressor......
It is common practice to specify the pump suction line one size larger than the pump discharge line in order to increase the Net Positive Suction Head available (NPSHA) to the pump. A smaller suction line the same pipe size as the discharge line would result in more pressure drop in the suction line and reduce the amount of head available to the suction side of the pump. This in turn would result in an operating point closer to cavitation of the pump.
