RAC 102: Air Conditioning I

GENERAL INFORMATION:

 Course Title: RAC 102 Air Conditioning I

Campus: CTEC

Initiator: Bertoldo Esteban Jr.

Date: April 26, 2021

Course Description:
          This course introduces the student to the fundamentals of air conditioning, installation, preventive maintenance, and repair of air conditioning systems. Practical exercises include dismantling and assembling mechanical parts, refrigerant recovery, system reprocess, and system electrical circuits. Troubleshooting and repairs focus mainly on window type and split type air conditioning units up to 5 tons of refrigeration (TR) for mechanical and electrical defects. Safe handling and storage of refrigerants are emphasized. The students must observe the good practices in servicing air conditioning systems as guided in the Montreal Protocol and the Kigali Amendments. At the completion of this course, a student must be able to perform preventive maintenance, installation, troubleshoot, and repair air conditioning systems.
