Fundamentals of Refrigeration and Air Conditioning

Course Overview

The aim of this qualifications is to provide the learner with the knowledge and skills to work on simple understanding of Refrigeration and Air-conditioning fundamentals. Ideally suited to those with a little or no knowledge of the subject. The course consists of different refrigeration cycles and understanding of psychometry and psychrometric processes used for the purpose of air-conditioning.

The course is designed for an apprentice or beginner who would like to work as an AC Mechanic.

The candidate should have basic knowledge in fundamental science.

Upon completing the training course, candidates will be awarded a ‘Certificate of Attendance’ from NTI, attested by the Ministry of Manpower.
