Overview
Credit: 3 PDH
Length: 61 pages
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.
