How to Cut Your Refrigeration Equipment's Energy Consumption by 30% in Your Shop or Restaurant
Why the energy consumption of refrigeration equipment matters
In a food shop or restaurant, refrigeration equipment is one of the largest sources of electricity consumption. Industry estimates show that fridges, display fridges and cold rooms can account for 40% to 60% of a site's total electricity use. The good news is that, with a few simple and well-applied measures, you can significantly reduce this expense — sometimes by 30% or more.
Whether you run a small supermarket, a pastry shop or a restaurant, the tips below are practical, easy to implement and can deliver real savings on your energy bill.
1. Check and set temperatures correctly
One of the most common mistakes is setting the temperature lower than necessary. Every degree colder means higher energy consumption.
- Display fridges for drinks and dairy operate optimally between +2°C and +5°C.
- Display fridges for confectionery products are recommended at +4°C – +8°C.
- Freezers should not be set below -18°C unless there is a specific requirement.
Check the internal thermometers regularly and make sure the set temperature matches the actual needs of the products on display.
2. Clean the condensers and filters periodically
A condenser covered in dust works much harder to maintain the desired temperature. The direct result: increased energy consumption and accelerated compressor wear.
Recommendation: Clean the condensers at least once every two months, or more frequently if the space is dusty. This simple operation can reduce consumption by up to 10% and extends the service life of the equipment.
3. Ensure proper ventilation around the equipment
Refrigeration equipment needs space to dissipate heat. If units are positioned too close to walls, other machinery or areas with high temperatures (near ovens or heat sources), the compressor will have to work harder.
- Leave a minimum of 10–15 cm of clearance at the back and sides from walls.
- Avoid placing display fridges in direct sunlight.
- Ensure good room ventilation, especially in summer.
4. Don't overload display fridges and avoid frequent door openings
Every time a door or lid of a refrigeration unit is opened, warm air enters the interior. The compressor starts immediately to compensate. Staff habits matter enormously in this regard.
Train your staff to open doors quickly and purposefully, not to leave equipment open while arranging stock, and not to obstruct the automatic closing mechanism.
Also, do not overload display fridges beyond the recommended capacity — internal air circulation is essential for uniform and efficient cooling.
5. Invest in energy-efficient refrigeration equipment
If you are working with older equipment, over 8–10 years old, it may be consuming 30–40% more energy than current models. Technology has advanced significantly: quieter compressors, cooling systems using eco-friendly refrigerant gases, integrated LED lighting and superior thermal insulation.
MODACO display fridges, manufactured in Romania in Găești, Dâmbovița county, are designed with a focus on energy efficiency and durability. With over 30 years of experience in the production of commercial refrigeration equipment, MODACO offers tailored solutions for food shops, supermarkets, pastry shops, restaurants and hotels.
By choosing new, efficient equipment, you can recoup the investment through energy bill savings in just a few years.
6. Schedule defrost cycles and regular maintenance
Ice build-up on the evaporator significantly reduces cooling efficiency and increases consumption. Set the automatic defrost cycles at optimal intervals and make sure the system is functioning correctly.
An annual technical service carried out by an authorised technician can identify problems early: worn door seals, insufficient refrigerant charge or components approaching the end of their service life.
Conclusion: the savings are within your reach
Reducing the energy consumption of your refrigeration equipment does not require major investment. A few good habits, regular maintenance and, where applicable, replacing old equipment with modern units can make a difference of 20–30% on your monthly energy bill.
