What Does an Orifice Tube Do in an A/C System? Technician.Academy
Orifice Tubes. The orifice tube is the dividing point between the high pressure and low pressure side of a CCOT system. Orifice tubes are probably the most commonly used refrigerant metering devices. The orifice tubes in use today measure approximately three inches in length and consist of a small brass tube, surrounded by plastic, and covered.

Clutch Cycling Switch In a (CCOT) cycling clutch orifice tube system, there's a constant pressure drop from the fixed orifice tube. It doesn't change its output according to demands like an expansion valve. A clutch cycling switch activates and deactivates the compressor clutch instead.

AC is a fairly complex system. While it's engaged and disengaged with a simple push of a button, there's a lot more that goes on behind the scenes to make it work. An AC in a vehicle is made of numerous components such as the compressor, evaporator, condenser, AC accumulator (dryer), and orifice tube.

How Your Car's AC Works Related: AC & Climate Control Print Share Surely you know what air conditioning is, but do you know how it works? Contrary to what you might expect, AC systems do not create cool air. Instead, they cool the air by removing hot air and moisture.

A (CCOT) cycling clutch orifice tube system has an accumulator and a cycling switch attached. The accumulator is on the low side of the system, after the orifice tube. Orifice tubes can become clogged and severely hamper A/C performance. It is essential to replace the old tube with the correct tube. Follow the manufacturer's recommendations.

1. AC system performing worse than usual and blowing warm air One of the first symptoms of a problem with the AC expansion valve or orifice tube is an underperforming AC system. The AC expansion valve and orifice tube work together to regulate the flow of the AC system.

$377.49 - $411.10 Price range for all vehicles ( 555) If your air conditioning (AC) has been less than helpful this summer, it may be the expansion valve (also known as an orifice tube). AC expansion valves regulate the flow of refrigerant through the AC system and if the valves fails they can cause problems with the whole system.

An orifice tube is simply a refrigerant metering device to control the rate of flow of refrigerant into the evaporator located in your dash. In the illustration below, you'll see that low pressure gas flows out of the evaporator coil and into the accumulator.

A: One of the most important parts of a vehicle's air conditioning (A/C) system is the orifice tube, which controls the amount of refrigerant that enters the evaporator. Its exact location can vary depending on the vehicle's make and model, but you can typically find the orifice tube between the condenser and the evaporator in the small.

An orifice tube and expansion valve both function as the dividing point between the high pressure and low pressure sections of the A/C system. The small diameter of the passage, while critical for the cooling system, makes an orifice tube susceptible to becoming clogged from debris within the system.

The can gets cold. The longer you hold down the button the colder it gets. In a nutshell, that's how an orifice tube makes the air conditioning system cold. On the other side of the orifice the low pressure liquid flows into the evaporator core. This looks like a mini radiator with aluminum fins. This device gets in the low 30 degree range.
