What causes the orifice tube to become clogged?
It’s usually easy to locate, because many manufacturers crimp the line that holds the orifice, preventing it from traveling down the tube towards the evaporator core. The orifice tube can become restricted and clogged with debris.
What does a fixed orifice tube look like?
A fixed orifice tube contains a small brass tube of a fixed diameter encased in a plastic case. The case contains a debris catching filter at each end.
Where is the orifice tube in an evaporator?
It’s located between the condenser and the evaporator core. It’s usually easy to locate, because many manufacturers crimp the line that holds the orifice, preventing it from traveling down the tube towards the evaporator core. The orifice tube can become restricted and clogged with debris.
Why does subcooled liquid enter the orifice tube?
Subcooled liquid entering the orifice tube is ideal for flooding the evaporator core of a CCOT, cycling clutch orifice tube system. Vapor entering the orifice tube will reduce the effectiveness of the refrigerant.
Where are the T top orifice tubes located?
The “t-top” orifice tubes are designed to be placed in the condenser, where as other orifice tubes are evaporator mounted. The small side (outlet) always faces the evaporator. **System debris will clog an orifice tube, and sometimes the orifice tube can be very helpful with the diagnosis of compressor/system issues.
It’s usually easy to locate, because many manufacturers crimp the line that holds the orifice, preventing it from traveling down the tube towards the evaporator core. The orifice tube can become restricted and clogged with debris.
Do you need to replace orifice tube, now problem?
Your compressor is going. You not only need to replace the orifice tube, but the compressor, condenser, accumulator and flush all the lines. If you don’t, the problem will just return and if you only replace the compressor, the shavings will make their way back to the new compressor and take it out.
