A commercial refrigerator, display chiller, or chiller freezer plays a crucial role in preserving food freshness while consuming electricity. However, adjusting the temperature based on different seasons can help reduce energy consumption and extend the lifespan of your refrigeration unit.
Since refrigerators work by compressing refrigerant gas to create a cooling effect, external temperatures in summer and winter can impact their efficiency. Setting the right temperature ensures optimal cooling performance, energy efficiency, and food safety.
Let’s explore how to adjust commercial refrigerator temperatures to achieve maximum efficiency while saving on electricity costs.
Ideal Temperature Settings for Different Seasons
1. Summer Temperature Settings (2-3°C for Chillers, -18°C for Freezers)
During hot summer months, commercial refrigerators work harder to maintain a stable temperature due to the high ambient heat.
✅ Set the temperature to 2-3°C for chillers and -18°C for freezers to prevent overworking the compressor.
✅ High temperatures cause longer compressor runtime, which increases energy consumption. Lowering the temperature slightly reduces strain on the refrigeration system.
✅ Avoid setting the thermostat too low, as it will force the compressor to run continuously, leading to higher electricity bills and potential damage to internal components.
💡 Pro Tip: If your display chiller or open showcase chiller is placed in a hot environment, ensure good ventilation around the unit to improve efficiency.
2. Winter Temperature Settings (3-6°C for Chillers, -16°C for Freezers)
In colder seasons, the ambient temperature drops, making it easier for the refrigerator to maintain cool temperatures.
✅ Set chillers to 3-6°C and freezers to -16°C during winter.
✅ If the surrounding temperature drops below 10°C, increase the thermostat to level 5 or higher to prevent overcooling.
✅ In extremely cold environments (0-5°C), food stored inside the chiller might start freezing. If this happens, store sensitive items in the freezer instead.
💡 Pro Tip: If your commercial refrigerator is placed in a cold room or warehouse with temperatures below 10°C, adjust the thermostat to prevent freezing and maintain proper cooling cycles.
Energy-Saving Tips for Commercial Refrigerators
💡 Set the Right Thermostat Level – In normal conditions, keep the setting between 1-3 for chillers and -16 to -18°C for freezers to balance energy efficiency and cooling performance.
💡 Optimize Placement – Position the refrigerator away from heat sources and in a well-ventilated area to improve energy efficiency.
💡 Minimize Door Openings – Reducing frequent door openings helps maintain a stable temperature and reduces compressor workload.
💡 Store Food Properly – Always allow hot food to cool before placing it inside the refrigerator. Wrap high-moisture items to prevent excess condensation.
Final Thoughts
Adjusting your commercial refrigerator, chiller fridge, or display freezer temperature settings based on seasonal changes helps lower electricity costs and extend the unit’s lifespan. By following these simple adjustments, you can achieve maximum cooling efficiency while keeping food fresh.
