9 ways to Reduce the Energy Costs of Commercial Refrigeration
Commercial refrigeration can have a significant impact on a business’s energy bills, particularly where fridges, freezers and other equipment operate continuously. Improving commercial refrigeration energy efficiency can help businesses reduce refrigeration running costs while maintaining reliable performance.
From keeping equipment properly maintained to upgrading older systems, there are several practical ways to reduce the amount of energy your refrigeration equipment consumes.
How Much Energy Does Commercial Refrigeration Use?
The amount of energy used by commercial refrigeration varies depending on factors such as the type and size of the equipment, how frequently it is used, its condition and how efficiently it operates.
Refrigeration systems that run continuously can represent a significant proportion of a business’s overall energy consumption. Older or poorly maintained equipment may also require more energy to maintain the required temperature.
Monitoring energy consumption and assessing the condition of your refrigeration equipment can help identify opportunities to reduce running costs. Professional advice can also help determine whether maintenance, changes to operating practices or newer equipment could improve efficiency and support energy efficient commercial refrigeration.
9 Ways to Reduce Refrigeration Energy Consumption
There are several practical steps businesses can take to reduce the energy consumed by commercial refrigeration equipment.
Keep Doors and Seals in Good Condition
Damaged or worn door seals can allow cold air to escape, forcing refrigeration equipment to work harder to maintain the required temperature.
Inspect doors, gaskets and seals regularly and arrange repairs or replacements where necessary. Keeping doors closed when equipment is not being accessed can also help minimise unnecessary energy loss.
Maintain Correct Temperature
Maintaining the correct operating temperature is essential for balancing energy use with food safety requirements.
Overcooling refrigeration equipment can result in unnecessary energy consumption, while temperatures that are too high can compromise stored products. Check temperature settings regularly and ensure thermostats and controls are operating correctly.
Clean Condenser Coils and Ventilation Areas
Condenser coils and ventilation areas can accumulate dust and debris over time. This can restrict airflow and make the refrigeration system work harder.
Keeping these areas clean can help equipment operate more efficiently. Cleaning should be carried out safely and as part of an appropriate maintenance routine.
Avoid Overloading Refrigeration Equipment
Overloading a refrigerator or freezer can restrict airflow and make it more difficult for the equipment to maintain its required temperature.
Allow sufficient space for air to circulate around stored products and avoid exceeding the equipment’s intended capacity.
Arrange Regular Servicing and Preventative Maintenance
Regular commercial refrigeration maintenance and servicing can help identify issues that may be affecting energy efficiency.
Dirty components, damaged seals and developing mechanical faults can all affect how efficiently equipment operates. Preventative maintenance provides an opportunity to identify and address these problems before they result in higher energy consumption or an unexpected breakdown.
Consider Upgrading Older Equipment
Older refrigeration systems may not operate as efficiently as newer models. If equipment is approaching the end of its useful life or requires increasingly frequent repairs, upgrading may provide an opportunity to reduce running costs.
When considering replacement equipment, look at its expected energy consumption alongside its capacity, functionality and suitability for your business.
For businesses considering a new system, commercial refrigeration installation can help ensure equipment is selected and installed appropriately for the intended application.
Choose the Correctly Sized Refrigeration System
Refrigeration equipment should be appropriately sized for the space, products and demands of the business.
Equipment that is too small may have to work harder to maintain the required temperature, while unnecessarily large systems may consume more energy than needed.
A professional assessment can help businesses identify the appropriate capacity and configuration for their requirements.
Use Efficient Defrosting
Excessive frost can affect the performance of refrigeration equipment and increase energy consumption. Modern systems may include automatic or demand-based defrosting features that activate when required.
Where equipment has a defrost function, ensure it is operating correctly and that excessive frost or ice is investigated rather than simply allowing it to build up.
Manage How Equipment Is Loaded and Used
How refrigeration equipment is used throughout the day can also affect energy consumption. Avoid leaving doors open unnecessarily and arrange products so that air can circulate effectively.
Consider how frequently equipment is accessed and whether operating practices can be adjusted to minimise the amount of cold air lost during normal use.
When Can Upgrading Equipment Reduce Running Costs?
Upgrading commercial refrigeration can be worth considering where existing equipment is old, inefficient or regularly requiring repairs.
Modern refrigeration systems can incorporate technologies designed to improve efficiency and reduce energy consumption. However, the potential benefits of an upgrade depend on factors including the existing equipment, how frequently it is used, and the requirements of the business.
A professional assessment can help determine whether maintaining existing equipment or investing in a new system is the more appropriate approach.
Why Correctly Sized Refrigeration Systems Matter
Selecting the right refrigeration capacity is important for both performance and energy efficiency. The system should be capable of meeting the demands placed on it without being unnecessarily oversized.
Factors such as available space, the type and quantity of products being stored, and how frequently the equipment is accessed should all be considered when selecting a system.

Frequently Asked Questions
How can I reduce the energy consumption of commercial refrigeration?
Start by checking door seals, maintaining correct temperatures, cleaning condenser coils and ventilation areas, avoiding overloading and arranging regular servicing. It may also be worth assessing whether older equipment or an incorrectly sized system is increasing energy consumption.
Does commercial refrigeration use a lot of energy?
Commercial refrigeration can represent a significant energy demand because equipment often operates continuously. Actual consumption varies depending on the type, size, age, condition and usage of the equipment.
Can servicing reduce refrigeration energy costs?
Regular servicing can identify issues that may cause equipment to operate inefficiently, such as dirty components, damaged seals or developing faults. Addressing these issues can help equipment operate more efficiently.
Does replacing old refrigeration equipment save energy?
Replacing older equipment can provide an opportunity to improve energy efficiency, particularly where existing systems are inefficient or require frequent repairs. The potential savings will depend on the existing equipment and the replacement system selected.
Why is refrigeration system size important?
A correctly sized system should provide the required cooling capacity without being unnecessarily large. Choosing appropriate equipment can help balance performance and energy consumption.
How often should commercial refrigeration be maintained?
The appropriate maintenance schedule depends on factors such as the type of equipment, how heavily it is used and the operating requirements of the business. A professional refrigeration engineer can advise on an appropriate maintenance plan.
