Which side is low pressure side of AC?

The low side service valve is located in the line that runs from the compressor through the evaporator (firewall) and up to the condensor on the low pressure (suction) side of the system.

Is the suction side the low side?

LOW SIDE - That portion of system from orifice in expansion valve through evaporator line or lines through compressor service valve to compressor reed valve. Also called suction side.

Is high side AC line suction or discharge?

The high side, or discharge line , will be the line connected to the compressor from the bottom or lower position. It will not be wrapped in insulation and will be warm to the touch. This is where freon exits the compressor as a liquid.

What color is the suction line?

The gauges and the flexible hoses that connect to the manifold to connect it to the system are color coded; blue is the low side of the system, red is the high side . The left-hand gauge is called a compound or suction pressure gauge. The right-hand gauge is called the high pres- sure or discharge pressure gauge.

What does high suction mean?

For a high-pressure suction to occur you could have an insufficient compressor . Meaning your refrigeration has a leaking discharge valve. This indicates that your compressor cannot provide the needed refrigerant to the evaporator to handle the cooling load.

Is low side suction?

The low side of a refrigeration system usually houses the evaporator, suction line, and any accessory components located within the suction line . Accessory components can include evaporator pressure regulator valves, suction filters and driers, crankcase pressure regulator valves, and suction accumulators.

Where is the suction line located?

The suction line connects the evaporator to the compressor , the discharge line connects the compressor to the condenser, and the liquid line connects the condenser to the expansion device. The expansion device is typically located at the end of the liquid line, at the inlet to the evaporator.

Is the suction side high or low?

LOW SIDE - That portion of system from orifice in expansion valve through evaporator line or lines through compressor service valve to compressor reed valve. Also called suction side.

Which line is the suction side?

The larger line typically carries a cool gas and is insulated. This is commonly referred to as the suction line, but it is also called the return line or vapor line. The smaller uninsulated line typically carries a warm liquid. It is most often called the liquid line.

Is the suction line the big or small line?

The larger line typically carries a cool gas and is insulated. This is commonly referred to as the suction line, but it is also called the return line or vapor line. The smaller uninsulated line typically carries a warm liquid. It is most often called the liquid line.
