Energy to Care = Energy Efficiency

Improving energy efficiency in industrial refrigeration is achieved by changing the business practices. Design standards and operation-and-maintenance practices that increase and maintain energy efficiency can also be adopted by users of industrial refrigeration.

Best Practices to Improve Energy Efficiency are:

  • To identify opportunities to increase electrical energy efficiency in industrial refrigeration systems. In most cases, a system that saves energy will also reduce peak demand.

  • To better understand industrial refrigeration as a system. Energy efficiency in industrial refrigeration includes both selecting efficient components and integrating those components into an efficient system. The goal is to minimize the energy consumption of the entire system. Frequently, one or more small constraints in a system can limit the efficiency of the overall system. In other instances, reducing the energy use of one type of component may increase the energy use of another. Understanding the way the system behaves as a whole lets us avoid building in “weak links” and allows us to strike an efficient balance between components.

  • To motivate system designers, contractors, plant engineers, and owners to consider life-cycle costs when installing or upgrading industrial refrigeration systems the equipment-supply and design-build businesses are very cost-competitive, and facility owners have limited capital budgets. Therefore, system design often emphasizes low initial cost rather than low life-cycle cost. Energy costs are the most significant ongoing life-cycle cost, and are a major component of the total present-value cost of a refrigeration system. 

  • To highlight non-energy benefits of energy-efficient practices In most situations, investments in energy efficiency can also reduce labor costs, increase productivity, increase product quality, and increase system reliability. 

  • To emphasize that best practices include more than just system design Commissioning and well considered operation-and-maintenance practices contribute importantly to the long-term energy performance of the system.

  • Encourage facilities to implement a robust energy management program a successful energy management program allows a facility to sustain and improve upon the efficiency benefits that have been achieved. Key elements of a successful energy management program include establishing an “Energy Champion” that is accountable for system energy use, tracking Key Performance Indicators (KPIs) of system efficiency, ensuring that key personnel receive appropriate training, and creating a culture that embraces a continuous improvement philosophy towards energy efficiency.
