Fundamentals and Future of Industrial Refrigeration Controls

Sunday, March 6, 1pm - 5pm

In modern refrigeration settings, controls are more powerful than they’ve ever been. This four-hour course will examine how controls are more and more becoming part of strategic operations, and why refrigeration professionals need to understand the architecture and capabilities of currently available control systems. We’ll look at the fundamentals of automated controls; the needs of end users when it comes to controls; opportunities in cloud-based controls and the accompanying security issues; and value-added benefits provided by automated controls.

Fundamentals of the Controls Infrastructure
Jeff Henness
Director of Engineering
VaCom Technologies

Understanding the fundamentals of refrigeration control systems is useful for anyone working in the industry. This presentation will help define the concepts of control system inputs and outputs (IO), control tasks, and provide description and comparisons of centralized vs distributed architectures. Special focus is given on network and communication structures in the different architectures including the human machine interface (HMI) and data visibility. Backup power and emergency & safety system integration is considered along with industry challenges and opportunities.

  • Distributed controls vs. centralized controls
  • Basics of digital inputs and outputs, analog inputs and outputs, and communications
  • How does selection of controls affect processes?
  • Pros and cons of wireless sensors

Operating with Automation 
Roberto Mendoza
Engineering Project Manager
Logix Controls
Cold storage warehouse and processing-plant owners face the constant challenge of managing their facility with minimal operating costs and maximum uptime. An automated industrial refrigeration system controller holistically controls each piece of equipment within a system by utilizing coordinated strategies to ensure that all components are working together to maintain or drive down temperature, rather just starting and stopping the equipment. Automation within a control system reduces operator errors, improves safety within the plant, and maximizes the life of the equipment. Automation also allows for a significant reduction of energy consumption through proven, energy efficient refrigeration strategies and the ability to shed load during peak demand-response times. 

  • Coordinated control–a holistic approach
  • An automated approach to troubleshooting
  • How can automation be applied by end users to make buildings more efficient?
  • Demand response/curtailment and working with facilities

The Future of Controls: Cloud-based Opportunities
David Jametsky
Business Development Manager, Industrial Refrigeration

What does the future of modern industrial refrigeration controls look like? With the ever-changing evolution of technology, we’re able to capture critical data and analyze it to help make systems much more efficient. By employing technology like IoT devices and cloud connectivity we can streamline facility operations over a secure connection from anywhere in the world. Cloud dashboards can now provide a visual interpretation of operating conditions as well as store data for advanced analytics. This gives end users a valuable tool for facility operation.

  • Smart technologies (IoT intelligence, cloud systems) and Net Zero
  • Advantages and disadvantages
  • Security concerns (hacking, user management)
  • Measuring what matters (cloud dashboards, cloud computing, analytics)
