Maximising Effectiveness in Commercial Refrigeration Systems

Refrigeration systems are crucial for industries reliant on food and medicines. They help to keep perishables at an optimal temperature, ensuring that foods and medicines stay fresh all day long. However, they can also be one of the largest energy consumers in commercial spaces.

Fortunately, there are several ways to maximise refrigeration efficiency and reduce energy costs. For a detailed exploration of these strategies and more tips on maximising the effectiveness of commercial refrigeration systems, we invite you to delve into the full article. Discover how these practices can not only enhance performance but also contribute to cost savings and environmental sustainability.

Proper system sizing

When it comes to commercial refrigeration Melbourne, the size of a system is crucial for energy efficiency. An HVAC unit that is too small will struggle to keep up with cooling demands, which can increase maintenance costs and extend the lifespan of the equipment. On the other hand, a unit that is too large will consume excess energy and cause unnecessary wear and tear. The proper sizing of an HVAC unit requires careful consideration and evaluation of many factors.

The first step in sizing a commercial system is to calculate the square footage of the building or rooms you want to cool. Next, you need to determine the number of people who will be in the space during the day. Add up the number of full-time occupants and divide it by eight hours to find the average daily usage. Then, factor in any kitchens and the number of windows. This will give you the total number of BTUs needed for a commercial space.

After calculating the BTUs of your space, you can divide that number by 12,000. This will provide you with an accurate number of tons for your refrigeration system. This will help ensure that you get the correct capacity for your business needs both now and in the future. Also, it will allow you to minimise part-load energy performance and save on utility bills.

Energy monitoring

Energy monitoring is one of the most important parts of energy efficiency when it comes to commercial refrigeration. It allows you to see exactly what is using your energy and when. This can help you identify any issues before they become too serious, saving you money in the long run.

By monitoring your energy usage, you can also identify any potential savings opportunities. These could include installing more efficient refrigerators, implementing an energy-saving cooling system, or changing the temperature set-points to reduce energy consumption.

Another great way to save on energy costs is by incorporating an electricity management system (EMS). These are software systems that allow you to track and analyze your business’s energy use. They can also give you reports on your energy consumption and performance, which can help you make more informed decisions about how to save more energy.

The food service industry uses a lot of energy, with refrigeration accounting for 25 per cent of the total energy usage in many commercial spaces. However, with some simple changes in operator behavior and diligent maintenance, it is possible to significantly cut energy consumption and costs. Other ways to optimise energy efficiency include setting timed alarms for cool room doors, establishing a loading and unloading policy, ensuring that insulation is in good condition and reducing heat gain by ensuring that the fridge doors are closed when not in use.

Door seals

Door seals in your walk-in coolroom or commercial refrigerator are vital to regulating the correct temperaure, protecting stock and reducing running costs. Ensure your seals are properly functioning by carrying out regular checks as part of your maintenance program. It’s also important that your seals are the correct profile and size fitted by a professional to allow the doors to close and seal properly. This will keep cold air in and hot air out, saving energy.

The type of door seal you choose will depend on a number of factors, such as its size and material. Some have open cells that allow the passage of air and water, while others are closed. Some also have flame resistance or EMI shielding. The best choice will be made according to the needs of your application.

To make sure you choose the right door seal, measure the gap around your door’s perimeter and its frame. Then, you will be able to calculate the average gap size. Then, find a door seal that’s the same size as your gap and install it on your door.

Aside from reducing energy consumption, a good door seal will reduce the infiltration of dust, drafts and light. They can also help to prevent moisture build-up and improve fire safety by slowing or stopping the spread of smoke and fire. They are available in a range of styles and colours to complement any design.

Air circulation

A well-ventilated commercial fridge is a must for businesses that rely on refrigeration to preserve food quality and ensure food safety standards. Proper air circulation keeps food fresh and prevents the formation of bacteria that cause spoilage, which can have a direct impact on business profits and customer satisfaction. It also enhances cooling efficiency and reduces energy costs.

However, improper ventilation can lead to problems such as ice-buildup, uneven temperature distribution, and fan failures. These issues require immediate attention to prevent a major disruption in refrigeration operations. The good news is that the problem can be solved through regular maintenance routines and airflow optimisation.

Airflow can be controlled by a simple device called a damper, which can increase or decrease the airflow in a given area. The more complex devices that can generate and condition airflow are called fans, which use the concept of pressure differential to generate flow. This is similar to how a waterfall works, in that the greater the pressure difference between two points, the faster the water flows.

Optimising refrigeration efficiency is crucial to lowering energy costs. When cold air is evenly distributed, the compressor does not need to work overtime to maintain the desired temperature. This can significantly cut electricity bills and align with sustainability goals. It can also increase the lifespan of the compressor by reducing the stress and wear on its components.

By implementing strategies to enhance efficiency, such as proper system sizing, energy monitoring, maintaining door seals, and optimising air circulation, businesses can not only reduce energy costs but also contribute to environmental sustainability.
