PURPOSE OF THE UNIT STANDARD 
To enable persons who assist suitably qualified or trained personnel involved in the installation, commissioning, maintenance and repair of equipment using refrigerants to carry out the following tasks:
  • To identify the type of refrigerant in containers and systems,
  • To demonstrate and explain the safe handling of refrigerant containers,
  • To name and explain the precautions to be taken to prevent harm to self, others, plant, and the environment when handling refrigerant containers.
  • To discuss the use of refrigerants in cooling plants 

  • LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
  • ABET Level 4,
  • An understanding of the basic principles of refrigeration 

  • UNIT STANDARD RANGE 
    Groups of refrigerants: CFCs, HCFCs, HFCs, HCs and natural refrigerants.

    Commonly used refrigerants, for example:
    CFCs : R11, R12, R502
