The Academic Supplement has been updated to Edition 2.0, to reflect technological change and to support the revised 4th Class Edition 3. The Academic Supplement Edition 2.0 now has a full-colour cover, and has a revised refrigeration section featuring:
- Consistent use of ASHRAE refrigerant data
- New, easier to read charts and saturation tables
- Extensive superheat tables
- Data for refrigerants currently in use, including natural refrigerants
In addition to the changes in the refrigeration section, the Academic Supplement Edition 2.0 also has an up-to-date periodic table with more useful data. Other content changes have been made to help learners with formulae application, and to re-validate physical constants.
The Academic Supplement Edition 1.0 will continue to support learners under the current SOPEEC syllabus. However, all learners (especially those studying the new 4th Class Edition 3) are strongly advised to use the new Academic Supplement in their studies and examinations.
