Chiller Systems

COURSE NO: M04-006
PDH CREDIT: 4
COURSE PROVIDER: A. Bhatia
Chiller Systems
Course Highlights

This online engineering PDH course discusses the applications of chiller systems.

 

A chiller can be generally classified as a refrigeration system that uses either a vapor compression or absorption cycle to cool.  Both the absorption and the mechanical compression systems have the evaporation and condensation of a refrigerant in common. In both systems, the refrigerant evaporates at low pressure to absorb heat and then condenses at higher pressure to reject heat to the atmosphere. Both systems require energy to raise the temperature of the refrigerant for the heat rejection process.

 

The difference is that the mechanical chillers use reciprocating, centrifugal or screw compressors that are powered by electric motors whereas in the absorption cycle uses heat (usually steam or direct fire) to raise the refrigerant temperature. Mechanical chillers are most commonly used in residential and commercial buildings whereas absorption systems offer an excellent choice for industrial applications there waste heat recovery is an essential element of the process.

 

This 4 PDH online course is applicable to mechanical engineers, design and construction personnel, technical staff and facility personnel who are interested in gaining a better understanding of chiller systems.

Learning Objectives

This PE continuing education course is intended to provide you with the following specific knowledge and skills:

  • How the mechanical compression cycle operates
  • What are the different types of mechanical compressors
  • What is vapor absorption refrigeration cycle, its components and applications
  • What do the terms efficiency and coefficient of performance mean
  • What are the functions of the different components of a chiller system
  • How is heat rejection achieved through contact and non-contact type cooling towers
  • What are the different types of refrigerants and their effects on environment
  • What are the principle guidelines in sizing, costing and selecting an appropriate chiller
  • Why is water treatment important in closed and open systems
  • What are the basic methods and procedures for testing, adjusting and balancing (TAB) of chiller systems
Course Document

In this professional engineering CEU course, you need to review Appendix C, "Chiller Systems" of the US Corps of Engineers Construction Engineering Research Laboratory (USACERL) technical report 99/20, May 1999.
