Where is the suction line on a compressor?
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 suction high side or low side?
SUCTION SIDE – Low side pressure (from expansion valve orifice to intake reed valve in compressor) . SUCTION THROTTLING – Control used to regulate flow of refrigerant from the evaporator to condenser.
Which is high side low side on AC?
The low side line of the system will have a larger diameter metal pipe than the high-side. The low side service port is usually located between the AC compressor and evaporator. The low side service port will have a black or blue plastic cap that needs to be removed.
What is suction in compressor?
Suction pressure is a term used to describe the pressure of a refrigerant gas at the intake point of a refrigerator or air conditioner compressor. Suction or, as it is also known, low side pressure, is one of the critical variants in the operation and diagnostic processes of air conditioning and refrigeration.
Is suction line big or small?
The larger one is your suction line and is usually insulated. It returns to the evaporator coil in the smaller line called the liquid line.
What should AC pressure be with engine on?
Q: What are normal pressures for 134a? Few ask what is the correct ac pressure on a car for 134a. The best running pressure for R134A is found between 22 and 57 in this type of system.
Why is compressor suction pressure so low?
This can be caused by low air flow (dirty filter, slipping belt, undersized or restricted ductwork, dust and dirt buildup on blower wheel) or a dirty or plugged evaporator coil. Checking superheat will indicate if the low suction is caused by insufficient heat getting to the evaporator.
Why is my suction pressure so low?
Many reasons can cause low refrigerant suction pressure, i.e.: low indoor temperature, dirty filters, restricted ducts, undersized ducts, closed dampers, frosted coils, restricted refrigerant line, restricted piston, incorrect piston, restricted strainer, bad indoor blower motor ect.
What causes a hot suction line?
The three causes for high discharge temperatures are: High condensing temperature. Low evaporator pressures and temperatures. High compression ratios.
What happens if suction line is too small?
If you decrease the suction line size the opposite happens, suction gas velocity increases and pressure drop increases. If you decrease the suction line size too much then you will restrict the mass flow resulting in low suction pressures/temperatures, as the compressor cannot overcome the increased resistance.
Where is the suction line on an air conditioner?
SUCTION SIDE – Low side pressure (from expansion valve orifice to intake reed valve in compressor) . SUCTION THROTTLING – Control used to regulate flow of refrigerant from the evaporator to condenser. Where is the suction line on an air conditioner?
Where are the suction and discharge ports on a compressor?
The suction side (low side) and discharge side (high side) ports are usually stamped with the letters “S” or “D” on the compressors head. COMPRESSORS Table of Contents
What is the suction pressure of an air compressor?
Suction pressure refers to the pressure of the refrigerant at the point where it enters the compressor after leaving the interior of the building. Measured when the compressor is running, this pressure will typically be in the region of 100 pounds per square inch (PSI). The exact suction pressure an air handling unit is designed to produce is …
How does the suction side of a refrigerator compressor work?
One side of the compressor uses suction to pull refrigerant gas through to the other side, where it is pushed out. If you need to conduct refrigerator repairs or want to find the suction side of the compressor, all you need to do is conduct a simple visual inspection.

Which is the low side of a gas compressor?
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.
