Class Description

Centrifugal chillers represent a significant HVAC investment for the building owner and each type of machine requires specific operating, servicing and maintenance practices to protect the investment. This course is intended for service technicians and operators of Carrier 19 series centrifugal chillers. The course covers fundamental principles of centrifugal chillers with in depth coverage of the operation and service techniques associated with most Carrier centrifugal chillers produced over the last 30 years. Carrier chiller models covered include 19D low pressure chillers and 19E,F and 19XR, 19XRV high pressure chillers. Participants learn how to operate, maintain, troubleshoot, and service both the low-and high-pressure machines (including PIC controls). Studies include: centrifugal refrigeration cycles, compressor theory, lubrication cycles, purge operation, refrigerants, heat exchangers, and heat transfer. The course also covers troubleshooting techniques and equipment needed to: record and analyze machine temperatures and pressures; determine performance using heat exchanger approaches; waterside flow rate analysis; maintenance requirements; and logging machine data. This course is mostly classroom instruction and includes numerous exercises using the classroom information to analyze performance. Successful completion of this course is required in order to attend the SER 130 Centrifugal Disassembly and Reassembly course.

Upon completion of this course, participants will be able to:

  • Use product literature to answer questions pertaining to design features, installation, start-up, operation, maintenance and parts
  • Determine system efficiency component enhancements
  • Determine proper flow through the cooler and condenser heat exchangers based on nozzle arrangement and pressure drop
  • Recognize 19D low-pressure machine's refrigeration, lubrication, motor cooling and purge cycles as well as educator and demister circuits
  • Recognize 19D high-pressure machine's refrigeration, lubrication, motor cooling and dehydrator cycles, as well as educator and demister circuits
  • Determine chiller capacity, 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.
