RAC Department introduction


Welcome to Refrigeration and Air Conditioning Technology.

Refrigeration and Air Conditioning Technology (RAC) is one of the most demandable technology amongst the emerging technology of Pabna Polytechning Institute (PPI).  The Department has been one of the most prestigious departments of PPI from the beginning. The (04) four year diploma in engineering of Refrigeration and Air Conditioning Technology (RAC) was started in 2016. Initially the course certificate was titled as a Diploma in Engineering Examination in Refrigeration and Air Conditioning Technology. Due to the market demand and for the betterment of the students, the BTEB has taken an initiative to rename the course certificate as a Diploma in Engineering Examination in Mechanical Technology having specialization in Refrigeration and Air Conditioning Technology. Roots of Refrigeration and Air Conditioning might easily be titled Application of Thermodynamics and Heat Transfer. The field of refrigeration and air conditioning are interconnected, but each also has its own province. The largest application of refrigeration, which is the process of cooling. in a similar manner air conditioning includes more than cooling. Throughout the study area, considerable emphasis is placed on the development of systematic procedures for analysis and troubleshooting, and on the responsible use of refrigeration and air conditioning technology. The Diploma in Engineering Course (RAC) prepares the student for a career in Refrigeration and Air conditioning field, with an emphasis on the technical areas of fluid and thermal energy systems and the heat transfers. In addition to theoretical and practical sessions in classrooms, the curriculum also includes industrial visits and on-site industrial training to gather hands-on experience of the field.
