Read FAQ. 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. It is usually easy to locate because the manufacturers' put a crimp in the line to keep the orifice tube from traveling down the tube towards the evaporator core.
The tube is sometimes tricky to remove with just needle-nose pliers. A special tool is available to pull stubborn orifice tubes. The orifice tube is always associated with an accumulator at the evaporator outlet. Orifice tubes are made up of three main parts:. The orifice tube must always be replaced when another important part of the circuit is replaced compressor, condenser, evaporator, accumulator.

Home Passenger car Air conditioning system for cars and air conditioning spare parts Orifice tubes for car air conditioning system. Thus, Orifice meters offer much more flexibility of operation.
Both are used to calculate the velocity of a fluid. A venturi meter can be used to measure the flow rates of all incompressible fluids gases with low pressure variations, as wells as liquids , whereas an orifice meter is generally used for measuring the accelerated flow through the apparatus. Some systems are designed so that the orifice tube is mounted in the high side of the liquid refrigerant line in the evaporator. 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.
Car air conditioning systems need the expansion valve, or orifice tube, replaced if the AC is blowing warm air or the AC system is broken. Faulty orifice tubes can also result in too little refrigerant flow through the evaporator.
If this is the case, the flow of refrigerant will not be enough to absorb the heat that is coming from the condenser. All the refrigerant has to go through the. So, it will work if installed backwards. If installed backwards it will suck to remove, and if there is debris in the system the screen has very little surface area so it will plug easily.
The receiver dryer must be regularly replaced. It is recommended that the receiver dryer is replaced every second year or whenever the circuit has been opened. Always install a new receiver dryer any time the compressor is replaced and always when a serious leakage has been noticed and repaired. Accumulators are in vehicles that have an orifice tube.
The accumulator has different roles: To provide compressor protection, preventing compressor failure due to liquid slugging. As part of the air conditioning system, the AC accumulator-drier transforms liquid refrigerant from the evaporator into gas form without refrigerant oil and debris to the AC compressor.
