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:
|
LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING |
UNIT STANDARD RANGE |
Groups of refrigerants: CFCs, HCFCs, HFCs, HCs and natural refrigerants.
Commonly used refrigerants, for example: CFCs : R11, R12, R502 HCFCs: R22, R123, R406A, R408A, R409A. HFCs : R23, R134a, R404A, R407C, R410A, R507. HCs : R290, R600a. Natural refrigerants : R717 (Ammonia). Typical applications of refrigerants, for example, comfort and industrial air-conditioning, cold rooms, freezer rooms, domestic refrigerators and freezers, automotive air conditioning and transport refrigeration units. Physical properties: smell, colour, toxicity and flammability. |

PROVIDERS CURRENTLY ACCREDITED TO OFFER THIS UNIT STANDARD: |
This information shows the current accreditations (i.e. those not past their accreditation end dates), and is the most complete record available to SAQA as of today. Some Primary or Delegated Quality Assurance Functionaries have a lag in their recording systems for provider accreditation, in turn leading to a lag in notifying SAQA of all the providers that they have accredited to offer qualifications and unit standards, as well as any extensions to accreditation end dates. The relevant Primary or Delegated Quality Assurance Functionary should be notified if a record appears to be missing from here. |
