IMPFT122K Principles of the refrigeration cycle in food
Overview
This standard is about the principles of the refrigeration cycle in food technology.
This standard is for you if you require a broad understanding of the technology of the refrigeration cycle. You need to understand how refrigerants work and the how the component parts of the cycle function.
Knowledge and understanding
You need to know and understand:
1 the definition and purpose of refrigeration
2 the definition and purpose of a refrigerant
3 the purpose of the refrigeration process
4 how liquid refrigerant takes up heat in an evaporator, from the food to be cooled
5 how refrigerant vapour is compressed and condensed into a liquid
6 the purpose of the expansion valve in the circulation of refrigerant
7 what the purpose of the refrigerant reservoir is
8 what substances are used as refrigerants
9 what the advantages and disadvantages of different types of refrigerants are
10 what the energy, sustainability and environmental concerns are in the use, maintenance and disposal of refrigeration equipment
11 what the safety precautions are in using and working with refrigerants
12 what the term ‘latent heat of evaporation’ means
13 why latent heat of evaporation is important in the refrigeration cycle
14 why refrigerants need to have a high latent heat capacity
