Energy Reduction

Commercial Refrigeration

Are you Looking to Reduce Operating Expenses?

With long hours of operation and constantly running equipment, refrigerated facilities are known for being extremely energy intensive. Commercial refrigeration equipment can account for 25 – 60% of electricity usage in grocery stores, convenience stores, restaurants, and distribution warehouses. 

If your business increasing relies on refrigeration, energy efficiency can save your company a lot of money. Benefits that come from using energy efficient commercial refrigeration include uniform cabinet temperatures, reduced heat output, and extended product life. Energy efficient retrofits can reduce energy-related operating costs by approximately 35%.

Controls

Coolers need to stay on 24/7/365 but evaporator fans only need to run at full speed when refrigerant is flowing through the evaporator, which is about 50% of the time. Upgrading to “smart” controls will help to manage these fans and monitor your entire system’s performance. Smart controls allow you to monitor your system from off-site and receive immediate alerts when problems occur.

Humidity Sensors

When warm air from inside your store hits the cold glass of a cooler door, condensation builds up and creates a foggy effect, known as “sweating.” Door frames are heated to prevent sweating and many stores run heaters 24/7/365. However, these heaters only need to run when humidity reaches 55% or higher. Installing humidity-sensing controls will help to regulate door heaters so they only run when necessary. Humidity sensors will keep products visible and reduce energy consumption.

Temperature Simulation

Thermostats in commercial refrigerators usually respond to air temperature around the thermostat element, not the actual temperature of the food being refrigerated. Air temperature can fluctuate rapidly as display doors are opened and closed, so that the refrigerator compressor cycles rapidly, wasting energy. Temperature simulators place a substance around the thermostat sensor to simulate the temperature of the food, not of the air. Energy savings in the range of 10% to 20% are achieved as the compressor runs more efficiently and builds thermal inertia.

LEDs and Refrigeration

Refrigerated display cases typically use fluorescent bulbs. However, light output from fluorescents can drop by 60% in cold temperatures. Fluorescent lights also emit a significant amount of heat and cause the refrigeration system to work harder to keep the air cool. LED Lighting uses 66% less energy than fluorescents, emits less heat, and performs better at cooler temperatures. Additionally, LEDs do not emit UV light like fluorescents, so your product packaging will not dull over time.
