670-06 - Chiller Design and Maintenance
Learning objectives
- Explain the role of a chiller in an HVAC circuit
- State specific conditions under which a water-cooled chiller would be better employed than an air-cooled chiller
- Sketch the flow paths of chilled water, refrigerant, and cooling water through a water-cooled chillerrs main components; include the following: evaporator, compressor, condenser, metering device, and cooling tower
- Give examples of two or more industry standard maintenance operations for industrial chillers
- Summarize the rationale of capturing heat exhausted by a chiller
Course overview
Industrial chillers are refrigeration equipment used with commercial HVAC circuits. Chillers continually remove heat from the system's refrigerant so cool air can be circulated throughout the facility. HVAC chillers are a substantial capital investment. For many facilities, they consume the most onsite energy. Capturing and reusing heat from the chiller, combined with routine maintenance, is key to maintaining target operating costs and performance levels.
The Chiller Design and Maintenance training course describes an industrial chiller's purpose. It explains how its main components work together to remove heat from the system's refrigerant, allowing the HVAC to provide cool air to the facility. It also discusses how heat exhausted from the chiller can be reused as energy elsewhere in the facility. This online course identifies general maintenance recommendations which help keep the chiller operating at peak performance. It covers:
- Chiller fundamentals and design
- Chiller components
- General chiller maintenance
Chiller Design and Maintenance is part of the Heating & Cooling Fundamentals training series.
