Where is the orifice tube located in an AC system?
Where is the orifice tube located in an AC system?
Some systems are designed so that the orifice tube is mounted in the high side of the liquid refrigerant line in the evaporator. In some systems, the orifice tube can be mounted in the condenser outlet, which can soften the hissing noises that traditionally are produced when this type of A/C system is turned off.
What is orifice in AC?
Orifice tubes for car air conditioning system The orifice tube is a tube with a given length and cross-section which expands the refrigerant but, unlike the expansion valve, it is unable to regulate flow rate and superheating. The orifice tube is always associated with an accumulator at the evaporator outlet.
Where is the orifice tube in an AC accumulator system?
Generally, the orifice tube is placed between the condenser and evaporator as shown in the picture below: AC accumulator orifice tube systems are found in some automobiles while other vehicles include an expansion valve in place of the orifice tube and a receiver-drier instead of the accumulator.
Where is the fixed orifice tube in a condenser?
A fixed orifice tube contains a small brass tube encased in a plastic case with a filter at each end to protect it from any debris in the system. It’s located on the high side between the condenser and the evaporator core.
Where is the orifice tube located in an auto?
The orifice tube may be located: In the inlet tube to the evaporator. Built into the high pressure liquid line. Inserted into the high pressure line near the condenser. The 5 different types of Auto AC orifice and expansion valves.
How do you remove the orifice tube in an evaporator?
Remove the orifice tube using needle nose pliers or removal tool. Note the orientation of the orifice tube. It must go back in the same way. Lubricate the O-rings on the new orifice tube with AC oil. Insert the new orifice tube into the evaporator or LLOT or SLOT.
Where is the orifice tube located in an air conditioning system?
If your system uses an orifice tube instead of an expansion valve, most of the procedures are nearly the same, the difference is that the orifice tube is located Inside the line going to the evaporator. Step 1: Locate the orifice tube.
Where is the expansion valve located in an air conditioner?
If your system uses an orifice tube instead of an expansion valve, most of the procedures are nearly the same, the difference is that the orifice tube is located Inside the line going to the evaporator. Step 1: Locate the orifice tube. The orifice tube will be inside the high-pressure line to the evaporator.
Remove the orifice tube using needle nose pliers or removal tool. Note the orientation of the orifice tube. It must go back in the same way. Lubricate the O-rings on the new orifice tube with AC oil. Insert the new orifice tube into the evaporator or LLOT or SLOT.
Why do you need an orifice for r-134?
The orifice tube allows for a higher flow of R-134 refrigerant during times when more cooling is needed, and a smaller flow of refrigerant when less cooling is needed.
