Chiller Plant Operations and Maintenance Training

Learning Outcomes

• Apply principles of thermodynamics and refrigeration cycles to chiller plant operation.
• Demonstrate safe start-up, shutdown, and routine monitoring procedures for chiller systems.
• Analyze chiller performance data to identify inefficiencies and potential faults.
• Implement preventive and corrective maintenance schedules for chiller components.
• Evaluate water treatment requirements and chemical dosing for condenser and evaporator systems.
• Design a basic troubleshooting log and report for common chiller plant issues.

Target Audience

This course is designed for plant operators, maintenance technicians, facilities managers, and engineering personnel responsible for the operation, maintenance, or supervision of chiller plants in commercial, industrial, or institutional settings.

Prerequisites

None — open enrollment. However, a basic understanding of mechanical systems and workplace safety is beneficial.

Course Outline

Practicals

Overview

Hands-on practical sessions are integral to this course, enabling learners to apply theoretical knowledge to real chiller systems. Learners will perform pre-start checks, routine maintenance, fault diagnosis, and system optimisation under supervision.

Practical Activities

• Chiller Pre-Start and Shutdown Procedures — Learners perform a complete pre-start inspection and startup sequence on a chiller unit, followed by proper shutdown procedures. (3h)
• Routine Maintenance Tasks — Learners execute routine maintenance including cleaning condensers, replacing filters, checking belts, and lubricating moving parts. (4h)
• Fault Diagnosis and Troubleshooting — Learners diagnose simulated faults (e.g., low refrigerant, faulty expansion valve, clogged strainer) using gauges and multimeters. (5h)
• Energy Efficiency Optimisation — Learners adjust setpoints, enable variable speed drives, and sequence chillers to improve efficiency while monitoring performance. (4h)

Summatives

Each delegate is assessed continuously throughout the course via daily exercises, scored practical assignments, and a final summative test at the end.

Practical Assignments — 30%

Practical assignments are observed and scored against a rubric during the practical sessions. Each delegate's practical mark is averaged into a single 100% score and contributes 30% to the final total.

Daily Exercises — 20%

Every training day ends with a multiple-choice exercise scored out of 100%. The scores from each daily exercise are averaged across the duration of the course to produce a Daily Average mark, which contributes 20% to the final total.

Final Test — 50%

On the last day a final summative test is written. It is a multiple-choice paper with multiple-answer questions: each question may have more than one correct option, and a single wrong selection on a question marks the entire question wrong — no partial credit. The final test is scored out of 100% and contributes 50% to the overall mark.

Final Total

Component	Out of	Weight
Practical Assignments (rubric-scored)	100%	30%
Daily Average (multiple choice)	100%	20%
Final Test (multi-answer multiple choice)	100%	50%
Final Total	—	100%

All marks are recorded on the AATICD LMS and visible to each learner under their account.

Certificate

How it works

• Certificates are auto-generated on the AATICD LMS as soon as the marks pass the 50% threshold.
• Each certificate is a branded PDF with the delegate's name, the course title, the unit standard ID, NQF level, credits, and the date of issue.
• You can download or print your certificate from your LMS dashboard at any time after issue — there's no reissue fee and no expiry date.
• If you scored under 50% you can sit the final test again at the next scheduled session at no extra cost.

Where to find it

Sign in to the LMS, open your dashboard, and your certificates appear under My Certificates. Each entry has a View / Download button and a print option.
