A chiller can be generally classified as a refrigeration system that uses either a vapor compression or absorption cycle to cool. Vapor-compression chillers are most commonly used in residential and commercial buildings, whereas absorption systems are often an excellent choice for industrial applications, where there is scope of waste heat recovery. An adequately functioning chilling system saves energy and maintenance costs, while providing a comfortable, healthy work environment.
This course discusses the basic principles and applications of the various types of chilling systems. It identifies the different components of chillers and explains how they interact with each other. It also outlines the procedures for inspecting, verifying, and accepting or rejecting a chilling system.
Learning Objectives
Upon completion of this course, participants will be able to:
- Explain how the mechanical compression cycle operates.
- Identify the different types of mechanical compressors, including reciprocating, centrifugal, and screw compressors.
- Describe the components and applications of a vapor-absorption refrigeration cycle.
- Calculate chiller efficiency and coefficient of performance (COP).
- Explain the functions of chiller components, such as evaporators, compressors, condensers, and expansion valves.
- Describe how heat rejection is achieved through contact and noncontact cooling towers.
- Identify different types of refrigerants and their effects on the environment.
- Apply the principal guidelines for sizing, costing, and selecting an appropriate chiller.
- Explain the importance of water treatment in closed and open systems.
- Describe basic methods and procedures for testing, adjusting, and balancing (TAB) chiller systems.
Certificate of Completion
You will be able to immediately print a certificate of completion after passing a multiple-choice quiz consisting of 20 questions. PDH credits are not awarded until the course is completed and quiz is passed.
