How do you determine what suction pressure should be in R22 air conditioning compressors suction line?
The proper suction pressure of any air conditioning or refrigeration system is determined by the type of refrigerant used and sometimes the amount of charge. : Suction pressure used is also directly related to the temperature required. : The temperature required in the evaporator relates to the pressure required in the suction line since, the fluid is at saturation in the evaporator. : Knowing the temperature required, use the fluid's saturation tables to find the corresponding pressure required.
Is the suction line the high side?
No, the liquid (discharge) line is the high pressure side. The suction line is the low pressure side.
Should the suction line be cold?
On split system installations, the suction line should be pitched towards the compressor at least Suction line should be insulated for 2 reasons: 1) so it does not drip condensation everywhere it passes through the homes interior space. ie attic, inside walls etc. 2) cool suction gas is what cools the compressor motor during operation, insulating the pipe carrying it helps prevent that gas from picking up heat from the surrounding air ensuring it remains an effective coolant for the motor. The original reply was also correct, an effort to pitch the suction line towards the compressor should be madr wherever possible to aid in oil return.
Why does a compressor frost on suction line?
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.
Why is your suction line warm?
your starving the evaporator
What temperature difference should be expected between the indoor line and the permanent suction -line ports on the reversing valve during the cooling cycle?
During the cooling cycle, a temperature difference of around 18-20°F is expected between the indoor suction line and the permanent suction line ports on the reversing valve. This temperature difference indicates proper operation of the system.
What is the liquid line and suction line?
The suction line is the big one. This line should be cold when the unit is on. The small line is the liquid line.
How should an air conditioner suction line feel to the touch?
A suction line is usually cold to the touch.
What is the superheat if the suction pressure is 60 psig and the suction line temperature is 40 degrees?
-5 something is wrong
What side of compressor is suction on 5.9 V8 1996 Dodge?
The larger line is suction. The larger line is the suction side which should be on the right side of the compressor......

Why must refrigerant in the suction line be slightly warmer than the saturation temperature?
Refrigerant in the suction line needs to be slightly warmer than the saturation temperature to prevent liquid refrigerant from entering the compressor. This temperature difference ensures that the refrigerant is fully vaporized before entering the compressor, preventing damage and maintaining efficiency.
Should air conditioner suction line be cool to the touch?
Yes It should be cold and sweatting
Why must refrigerant in the suction line be slightly warmer then the saturation temperature?
The refrigerant in the suction line needs to be slightly warmer than the saturation temperature to prevent any liquid refrigerant from returning to the compressor, which could damage it. This temperature difference ensures that only vapor refrigerant enters the compressor for proper and efficient operation.
What is the number one reason why pumps cavitate?
The number one reason why pumps cavitate is due to low pressure at the suction inlet, causing the fluid to vaporize and form bubbles. This can be caused by a variety of factors such as high liquid temperature, air leaks in the suction line, or a blocked or restricted suction line.
How do you tell the suction line in central air conditioning from the high side line?
The suction line will be the larger line going into the compressor.
Why compressor suction line ice forming in a refrigeration system?
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.
