A/C Performance Test Equipment

As a way to verify performance of a newly tested and filled a/c unit, a performance run test option can be added to your leak testing and a/c filling cycle as a final verification that the unit performs to the specifications required. This results in a single point process that includes:

  • System leak test
  • Product evacuation
  • Oil fill
  • Refrigerant fill
  • Unit operation and performance test

Typical test points include:

  • Compressor inlet and outlet temperatures
  • Suction and discharge pressures
  • Vent temperature
  • Ambient temperature
  • Ambient humidity

DataServ 3.0 records all data, calculates superheat and discharge pressures, and compares values to performance specifications. Test instructions and prompting is accomplished through DataServ also.
