Class Description

Efficient operation of air and water cooled chiller systems requires a though understanding of their operation and service procedures. Many of these chillers use scroll or screw compression technology. In this class the service technician will learn how to best operate, maintain, troubleshoot, and service the complete line of Carrier scroll and screw 30 Series air-cooled and water-cooled chillers from the past 20 years. Models covered include the 30GX/HX, RA/RB/RAP, and XA/XW. Studies include chiller refrigeration cycle, compressor theory, cooler heat transfer, water and air-cooled condensers. You will learn how to analyze performance by recording and analyzing refrigerant and water pressures and temperatures and calculating GPM flows. We also cover refrigerant controls, adjustments, charging, capacity control and capacity testing, and operation and troubleshooting of the electrical system, including timers, temperature controllers, operating and safety controls. This class is mostly done in the classroom however several lab exercise are done using the control simulators allowing students have hands on knowledge of chiller control operation. The skills learned in this class will allow operators to run machines more efficiently and service technicians to reduce service time and callbacks.

  • Setup and adjust controls
  • Identify the major components of a screw liquid chiller
  • Describe screw compressor operation
  • Identify refrigerant flow in a system
  • Measure refrigerant and water temperature delta T, LTD, gpm, and tonnage
  • Compare design and actual operating conditions
  • Troubleshoot and identify system problems using data from operating log sheets.

A cumulative score of 70% is required to pass this course. The score is a combination of attendance, class participation, and a demonstration of skills and knowledge through quizzes and/or work sessions.
