Low airflow, low refrigerant or restriction
No, the liquid (discharge) line is the high pressure side. The suction line is the low pressure side.
A compressor may frost on the suction line due to low refrigerant levels, which can lead to insufficient heat absorption and lower pressure in the suction line. This causes the temperature to drop below the dew point, resulting in moisture in the air condensing and freezing on the line. Additionally, poor airflow or a malfunctioning expansion device can exacerbate this issue by preventing proper refrigerant circulation. Regular maintenance is essential to avoid such frost buildup.

The diameter of the discharge line leaving the ac compressor would be smaller than the suction line, because the compressed gas in the discharge line is more dense.
Low airflow, low refrigerant or restriction
Frost on the suction line of an air conditioning system is typically caused by a combination of low refrigerant levels and low airflow. When the refrigerant level is insufficient, the temperature of the system drops, causing condensation to freeze on the suction line. It can also be exacerbated by restricted airflow, which prevents proper heat exchange and leads to the line becoming too cold.
Ice formation on the suction line of a compressor in a refrigeration system is typically caused by a combination of low refrigerant levels, poor insulation on the suction line, or a malfunctioning expansion valve. This results in the refrigerant temperature dropping below the dew point, causing moisture in the air to freeze on the suction line. It is important to address the root cause to prevent further issues with the system.
The suction line is the big one. This line should be cold when the unit is on. The small line is the liquid line.
The suction line will be the larger line going into the compressor.
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.
"What" on the suction line of an air conditioner indicates a problem?
Defective pressure switch not cutting out on hi-head pressure The compressor depends on the suction line for coolong the motor, if its low on freon then the suction line will not be cool enough to cool motor windings.
Common causes of suction line freezing in HVAC systems include low refrigerant levels, restricted airflow, dirty air filters, and issues with the evaporator coil. Solutions may involve checking and replenishing refrigerant levels, ensuring proper airflow by cleaning or replacing air filters, and inspecting and cleaning the evaporator coil. Regular maintenance and professional servicing can help prevent suction line freezing in HVAC systems.
