The low side, or suction line, will be the line connected to the compressor from the top or higher position. It will be cold to the touch and may be wrapped with insulation. This is where freon enters the compressor as a gas.
Which is the high pressure AC line?
The high side (high pressure components) of the AC system includes the AC Compressor, AC Condenser and the AC Receiver Dryer. ... The High Side AC hose carries the highly pressurized liquid refrigerant on the discharge side of the compressor to the expansion valve, which is the entry point of the low-pressure side.
Which line on the AC unit is the low side?
The low side, or suction line, will be the line connected to the compressor from the top or higher position. It will be cold to the touch and may be wrapped with insulation. This is where freon enters the compressor as a gas.
Which line is the suction line on air conditioner?
If you have an air conditioner, you have a suction line–that's the “cold” copper line that runs between the compressor and the evaporator, and it carries the cool refrigerant back to the compressor to be turned back into liquid. When your HVAC system is new, this line is insulated air-tight with 3/4″ insulation.
Which side is the suction side?
The suction side of the unit consists of the lines that lead into the compressor, often called the low side of the refrigerant system, since the pressure in these lines is much lower to the lines on the compressor output. The lines rarely have dials that automatically show pressure.
What color hose goes on the suction line?
Blue
What are the 2 AC lines?
There are two copper lines that run between the condenser and the evaporator coil. The larger line is known as the suction line, return line, or vapor line. It carries cool gas, so it must be insulated with tubing. The second copper line is small and bare, and it is commonly known as the liquid line.Jun 13, 2017
Which is the suction port on AC compressor?
The compressor has two ports and an inlet and outlet. The larger diameter hole is the suction port. Refrigerant is sucked into the compressor and then discharged through the outlet.
