CHILLERS Operation & Maintenance of Chilled Water Systems

Introduction

It is imperative that the water-cooling system(s) operates at maximum efficiency. In this hands-on chilled water systems course that participants will receive the critical information needed to increase the participant’s system’s reliability. The chiller is the heart of the refrigeration system which operates best with skilled technicians maintaining it. Gain hands-on practice and knowledge of instruments and test meters. Learn how to collect data and evaluate the chiller operation equipment. Become familiar with approach temperature and to interpret it in terms of the system operation.

Objectives

    By the end of the training, participants will be able to:

    • Utilize HVAC concepts as they apply to air conditioning, refrigeration, heating, chillers, boilers, and pneumatic comfort controls
    • Perform HVAC operation, preventative maintenance, and troubleshooting
    • Participants of the operation of the chillers and maintenance course will learn preventive maintenance and troubleshooting methods to ensure the system is always operating with the most efficiency and cost savings
    • Receive information on the latest techniques and technology

Training Methodology

This is a highly interactive training course with opportunities to advance your opinions and ideas. Participation is encouraged in a supportive environment. To ensure the concepts introduced during the program are understood, they will be reinforced through a mix of learning methods, including lecture-style presentations, open discussion, case studies, simulations, and group work.

Who Should Attend?

This course is intended for all Chilled Water System Operators, Refrigeration System Operators, HVAC maintenance and Repair Technicians, Plant & facility maintenance technicians, Building engineers, Building managers & superintendents, Plant & facility managers, Environmental health & safety personnel, Apprentice and experienced HVAC technicians, Stationary engineers, and Energy management personnel as well as those needing a basic seminar in Chilled Water (Chiller) systems.
