Evaporators, compressors and condensers often operate at less than their full capacity. In this video series, Rob discusses these integral industrial refrigeration components and reviews common best practices to improve performance.
Who should watch?
Industrial refrigeration technicians, contractors, specialists, system operators, maintenance personnel, design engineers and equipment vendors; production staff; facility owners and managers; and anyone with basic knowledge and interest in industrial refrigeration best practices.
1. Evaporator operation and defrost (19 minutes)
Evaporators function to remove heat, but how they do it can affect a facility’s energy use. Rob discusses evaporator fan control, defrost set points and overall operations. As a result of this video, you’ll be able to:
- Describe the energy benefits of evaporator fan cycling and efficient defrost control.
- Explain why proper temperature control set points are important.
2. Compressor efficiency and sequencing (17 minutes)
Compressors account for the largest portion of horsepower in a refrigeration system. Rob discusses properly set up and efficient operation. As a result of this video, you’ll be able to:
- Calculate the efficiency gained from an increase in compressor suction pressure.
- Describe the different methods of compressor part load control and efficient compressor staging set up strategies.
- Discuss the energy impact of proper compressor vapor injection.
3. Optimizing condenser performance (16 minutes)
The proper operation and maintenance of condensers can have large impacts on both condenser and compressor energy use. Rob discussed the energy impact of condensing pressure reduction, wet bulb approach control, proper condenser staging and overall condenser operation. As a result of this video, you’ll be able to:
- Calculate the energy savings of condensing pressure reduction.
- Explain wet bulb approach control and its benefits.
- Discuss the most efficient condenser staging and the energy impact of proper condenser maintenance.
Senior Project Engineer
Rob conducts retro-commissioning projects at industrial facilities with the primary task to identify no-cost/low-cost energy efficiency opportunities. Energy savings from these efforts are tracked with energy management information system software, which tie results to specific actions that are reported to facility personnel. He has conducted various seminars including energy management sessions for all levels of corporate clients. Rob has a bachelor’s degree in mechanical engineering, an MBA and is a registered professional engineer in the state of Utah.
