An orifice tube is an expansion device that controls refrigerant volume in front of the A/C evaporator. This tube prevents your evaporator from freezing. Unlike an expansion valve, an orifice tube is not adjustable. Other parts work with the orifice tube to regulate volume as the compressor cycles on and off as needed. Fig 2: Orifice Meter Diagram (Schematic) Inlet Section: The fluid from one end of the pipe enters through this section. The diameter of the section depends on the flow to be measured. Orifice Plate: A device used for measuring flow rate, lowering pressure, or restricting flow is called an orifice plate (often called a restriction plate). These ...TUBES AND ORIFICES R.

A/C Evaporator Core Orifice The A/C evaporator core orifice (19D990) should be replaced whenever the A/C compressor (19703) is replaced for lack of performance (internal damage). The A/C evaporator core orifice, located in the condenser to evaporator tube (19835), cannot be serviced in detail as a component of the line.The most popular is to upgrade to VIR eliminator. This like the POA eliminator, turns a bi-pass system into a cycling system. 1977-Newer Models with Accumulator. The accumulator is most often installed on the evaporator, near the firewall. It is the earliest of the modern cycling sytems GM used. These systems had a pressure switch and orifice tube.Description Orifice plate showing vena contracta. An orifice plate is a thin plate with a hole in it, which is usually placed in a pipe. When a fluid (whether liquid or gaseous) passes through the orifice, its pressure builds up slightly upstream of the orifice but as the fluid is forced to converge to pass through the hole, the velocity increases and the fluid pressure decreases.Charging a A/C system by subcooling. Determine your target subcooling. This is usually displayed on the back of the nameplate, located on your condensing unit. If not, 10-15 degrees F will get you ballpark range. With the unit running, connect your high side refrigerant gauge, to the liquid line port, or fitting.Feb 2, 2011 · Step 8: Charge the System.
