Course Learning Outcomes
  1. Describe the types of problems and related remedies associated with water problems that can occur in the different types of water and steam systems.
  2. Describe how to prepare, clean, start up, and shut down a steam boiler, hot-water boiler, reciprocating liquid chiller, centrifugal or screw liquid chiller, and an air handler and a forced-air distribution system, and demonstrate how to clean condenser tubes.
  3. Identify the steps in the system design process, the principles that affect the selection of equipment to satisfy the calculated heating and/or cooling load, and perform a load calculation of a residence.
  4. Identify the basic components, various accessories, control devices used, and perform an operational checkout of a commercial/industrial refrigeration system.
