Overview

AIR CONDITIONING & REFRIGERATION – ACR

Course Outcome

NB: This module covers COMMERCIAL type systems featuring a semi-hermetic compressor.

4 Modules

The complete course consists of 4 video modules and 2 PDF manuals which include self-assessment

Module 1 – System Overview

 At the end of this module the learners will be able to:

  •  Describe the fundamental principles of a typical air-cooled, vapour compression refrigeration system
  • Explain the purpose and function of the major components, which comprise a typical mechanical refrigeration system

 Module 2 – Tubework

 At the end of this module the learners will be able to:

  •  Identify ACR tubing
  • Correctly handle and cut ACR tubing
  • Create flared ends
  • Create swaged joints
  • Create crimped joints
  • Create accurate bends

 Module 3 – Service Procedures (1)

 At the end of this module the learners will be able to:

  •  Describe the functioning of a typical gauge-manifold
  • Correctly connect a gauge-manifold and set service valves
  • Perform a pressure and leak test on an air-cooled refrigeration unit
  • Perform an evacuation and vacuum analysis to an air-cooled refrigeration unit

 Module 4 – Service Procedures (2)

 At the end of this module the learners will be able to:

  •  Perform a vapour-charge to an air-cooled refrigeration system
  • Describe / demonstrate basic maintenance and diagnostic test procedures
