Refrigeration Cycle online course launched by Star Refrigeration

The Refrigeration Cycle course - Vapour Compression Cycle - is part of the first available online training programme - Refrigeration Fundamentals - contains four 30 minute modules covering Thermodynamics, Vapour Compression Cycle, Gas Properties and Laws, and Pressure & Pressure Measurement.

The Refrigeration Cycle course is available to study online by accessing This eLearning course has no entry requirements and it is targeted to anyone interested in Refrigeration training.

This module covers:

  • Compression
  • Condensing
  • Expansion
  • Evaporation
  • Heat Transfer
  • Latent Heat
  • Pressure/Enthalpy Diagram
  • Refrigerant Flow
  • Summary and Summative Quiz Assessment.

Any student that has undertaken the Refrigeration cycle course will be able to:

  • Explain the structure, purpose and operation of the Vapour Compression Cycle using an air-cooled condenser and direct expansion (DX) evaporator.
  • Describe the purpose and structure of the Vapour Compression Cycle.
  • State the four stages of the Vapour Compression Cycle and describe their structure and function.
  • Explain the relationship between pressure and temperature, and its effect on the heat transfer of a refrigerant.
  • Explain how heat is transferred during the evaporation and condensation stages of the Vapour Compression Cycle.

Successful students will receive a company certificate/diploma in recognition of their achievement.

Star's Aim

The aim of this innovative learning project is to be a convenient tool to help engineers and technicians keep up to date and to acquire new knowledge.
