• The Symptoms of a Restricted TXV 2017 01 09 ACHRNEWS

  Jan 09, 2017 A small amount of refrigerant vaporizing will cause a lower pressure. High Superheats — High superheats also are caused by the evaporator and compressor being starved of refrigerant. With the TXV restricted, the evaporator will become inactive and run high superheat. This will cause the compressor superheat to be high.

• Sizing Pressure Relief Devices AIChE

  A pressure-relief device protects process equipment from the hazards of high (or low) pressure in a process. It operates by opening at a designated pres-sure and ejecting mass from the process. The ejected mass contains energy — the removal of the energy reduces the process pressure. A previous article in CEP (1) provided a basic overview
