Course Description
Covers the practical application of the laws of thermodynamics and heat transfer to operating, maintaining, and repairing hot water, steam, chilled water, refrigeration, heating, ventilating, and air conditioning systems found in todays industrial facilities, manufacturing plants, and processing plants. Includes the physical properties of water and refrigerants. Includes operation and servicing of controls and components of these systems. Includes chemical water treatment for boilers, chillers and cooling towers. Emphasizes achieving optimal energy use for thermal systems operation. Emphasizes safe work practices around thermal systems. Audit available.
Addendum to Course Description
Required Course for Apprentices registered in the Millwright/Industrial Maintenance Technician Apprenticeship Program. It is open to any other student but requires Department Permission to take this course.
Intended Outcomes for the course
- Use the principles of thermodynamics and heat transfer to effectively operate, repair, and maintain hot water boilers, steam boilers, and water chillers at an industrial worksite.
- Use the principles of thermodynamics and heat transfer to effectively operate, repair and maintain forced-air heating, refrigeration, ventilating, and air conditioning systems at an industrial worksite.
- Operate and maintain chemical water treatment systems for hot water boilers, steam boilers, cooling towers, and water chillers at an industrial worksite.
- Operate and repair control systems for a variety of HVAC/R equipment at an industrial worksite.
- Adjust a variety of thermal systems to obtain maximum energy efficiency at an industrial worksite.
- *Demonstrate the functions of trade specific industrial systems (*required statewide outcome).
- *Describe procedures for proper removal and disposal of hazardous materials (*required statewide outcome).
Course Activities and Design
Course Design is primarily lecture coupled with in-class demonstrations of selected types of thermal equipment. Course activities include guest speakers from service, installation, design, and distribution companies as well as guided field trips to selected industrial sites.
Outcome Assessment Strategies
Assessment will be accomplished using skills' checklists filled out by an adequate sampling of Millwright/Industrial Maintenance Technician Training Agents and/or an Apprentice's Journey Person
