HVAC&R: Chillers - Leak Check & Electrical

About

Make sure the temperature is just right at your facility with this course, one in a comprehensive seven-part cd-rom series. It will teach workers how HVAC components work together and how regular maintenance will help ensure operating efficiency. Designed to give technicians a detailed understanding of air handlers, cooling systems and towers, condensers and electrical systems -- as well as an overview of basic troubleshooting techniques.

The chiller is one of the most complex components in an air cooling system; and, with proper maintenance, it can operate reliably for years. This course will help technicians avoid the trouble and expense of a major breakdown by teaching them how to perform a leak check, conduct basic electrical testing, return the chiller to operation, and follow crucial troubleshooting techniques.
