Cascade Energy is Your Cooling Expert
Cascade Energy engineers have consistently maintained a sharp focus on industrial refrigeration and vapor-compression ammonia systems.
Through the completion of well over 2,000 refrigeration projects, our engineers have identified many energy efficiency measures that are under-implemented, yet highly impactful. As part of Cascade’s approach of pursuing more comprehensive energy-saving projects, we work with clients and their trusted vendors to include these measures where they are a good fit.
Here are our top energy efficiency projects in refrigeration:
Quick Win, Low-Cost Projects
- Adjust suction pressure setpoints
- Adjust condensing pressure setpoints, reduce minimum condensing pressure, troubleshoot barriers
- Improve compressor sequencing, staging
- Repair underperforming evaporators
- Improve condenser sequencing, staging
- Get the most from fan cycling or evaporator fan VFD controls
- Improve liquid subcooling, use/tune economizing
- Improve door practices, dock doors, freezer doors
- Improve defrost
Strategic, Capital Projects
- Replace high powered electric freezer doors with low powered doors, with roll up insulated panels, fans, minimal heat.
- Install VFDs on screw compressors
- Purchase efficient condensers, evaporators
- Replace/upgrade control systems
- Install VFDs for evaporator/condenser fans
The Department of Energy’s Better Plants Program
The Better Plants program helps participants identify energy conservation opportunities, quantify savings, and implement projects. Cascade Energy produced the curriculum for and provides in-person and remote training through their program on refrigeration. The curriculum was designed to promote collaboration among range of facility staff, including refrigeration operators, plant engineers, and corporate energy managers.
Industrial Refrigeration Best Practices Guide
Our book, the Industrial Refrigeration Best Practices Guide, now in its third edition, identifies and discusses best practices for making industrial refrigeration systems both energy efficient and productive. The highest levels of efficiency in these systems are achieved through a combination of design, construction, commissioning, operation, maintenance, and a robust energy management program.
This book is for those seeking insights into approaches to refrigeration systems that cost less to operate, are reliable, can maintain accurate temperatures in refrigerated spaces, help ensure that processing equipment operates consistently, and can meet varying production needs.
