Utility Cost Management
Plant-wide Operational Goals, and Utility Power Management
Lowering your refrigeration energy costs is not always a straight-forward proposition. Sure, you want to achieve a desired refrigeration effect for the least cost — but that often involves more than just maximizing energy efficiency at the individual equipment item level. Everything from plant-wide energy conservation opportunities to company operational goals to utility power management objectives must be considered in designing a control system.
Logix has the broad energy management experience and successful track record you can trust to minimize one of the few costs you can actually reduce — your energy bill.
Since its inception in 1990, Logix has pioneered award-winning, energy-saving control systems for refrigeration equipment. Today, Logix delivers even greater energy savings by delivering comprehensive plant-wide equipment control that coordinates operation of the entire refrigeration system for maximum efficiency.
• Coordinated Refrigeration System Control
• Load Shifting
• Load Shedding / Demand Limiting
• Real-time Pricing Response
• Interruptible Service Support (Automated Shutdown)
• Systematic Equipment Restart Procedure
• Lighting, HVAC, Battery Charger & other Load Management
• Intelligently coordinates operation of all refrigeration system components, greatly minimizing the power spikes associated with the random and volatile nature of independent equipment control
• Stabilizes evaporator, compressor and condenser loads, resulting in lower energy costs for the same or better refrigeration performance
• Reduces energy use during high-cost, peak-power billing periods by operating equipment at lower energy use settings (raising allowable temperatures and pressures) and limiting equipment operation as determined by plant personnel
• Automatically lowers temperatures prior to the peak cost periods to achieve a thermal “flywheel” effect that maintains refrigerated products within desired temperature ranges
• Manages equipment operation to limit power consumption to a pre-set kW level without negative impact to cooling objectives
• Automates shedding (shut-down) of eligible equipment according to a user-defined equipment priority list, flattens power spikes, improves power factor and contains energy usage
• Monitors current utility power costs via internet or other link
• Permits owners to choose various equipment operating scenarios, from all-on to all-off and anything in between, for a range of kWh price levels
• Turns off equipment in a safe, orderly and timely manner with minimal or no labor cost for plants that must go off utility power after short notice
• Minimizes labor and potential utility penalty expenses associated with shutdown response and avoids power demand spikes with equipment restart (see “Restart” item below)
Systematic Equipment Restart Procedure
• Provides for the smooth, gradual starting of plant equipment after a power failure or shutdown occurs
• Contains electrical demand charges that result from turning on numerous motors in a refrigeration system start up
• Manages the shedding, limiting, shifting, shutdown and restart of other facility electrical loads (in conjunction with refrigeration equipment) to maximize benefit of the plant-wide system energy management tools Logix provides
