2026 Lim Jae-gi's Air Conditioning and Refrigeration Engineer Written Exam (Theory + Past Questions)
 |
Description
Book Introduction
With economic growth, demand for air conditioning and refrigeration is increasing day by day. Now, we have reached a point where we need to move beyond simple heating and cooling to alternative and new energy sources that are energy-saving and prevent global warming.
Accordingly, I wrote this book based on my practical experience in the air conditioning and refrigeration field and my experience teaching students taking the air conditioning and refrigeration engineer exam.
This book is based on the basic knowledge that must be known by air conditioning and refrigeration technicians and the content that was tested on the exam.
Even a little basic engineering knowledge is required to understand the concepts, and we've included illustrations and photos to help you remember them over time.
This book contains detailed explanations of the principles and basic theories so that it can be used not only for written exams but also for practical exams.
Past exam questions are included with explanations to provide test takers with practical experience with various types of problems.
