Replacement of linear or vertical chillers and freezers
The project aims to replace old chillers and freezers with new generation refrigeration units that are closed, well insulated, fitted with more efficient fans and LED lighting. Defrosting is optimised and it is possible to increase the temperature regime of the evaporator circuit.
This system applies to supermarkets or grocery stores with chillers and freezers to store food in store. By installing this technology, which has been available on the market for more than 5 years, the company can save on its electricity bills and reduce its carbon footprint. However, implementing this measure can be complex and requires the temporary shutdown of production during the technical installation stage.
Installation of a transcritical CO2 refrigeration system
The project involves replacing an existing conventional, centralised, or direct expansion installation with a refrigeration system using CO2 as a fluid which is transferred in a transcritical or subcritical cycle (cascade or refrigerant) to the units diffusing the cold (refrigerated units, cold room evaporators, etc.) for a positive or negative application, or both.
This system applies to existing commercial buildings, particularly food distribution premises. This includes spaces intended for the display or self-service of fresh products for the public, such as hypermarkets, supermarkets, and small food stores. Drive-through facilities and click and collect points allowing the public to pick up their purchases without actually entering the store (the “drive-through” concept) as well as refrigerated warehouses.
Setting up this new technology will allow the company to save electricity, while reducing its carbon footprint. However, implementing this measure can be complex and requires the temporary shutdown of production during the technical installation stage.
The project involves replacing hot steam generation with humidification based on ultrasonic low-temperature water mist.
Installing this technological innovation can allow the company to save up to 95% on electricity consumption during the humidification stage, as well as 5% during the cold generation stage. This measure is not easy to implement and would entail a medium-to-long term return on investment. The measure does not require a production shutdown while the technology is being installed.
Controlling the operation and running costs of your company’s cold production system
Cold production is used to cool a room or an element, preserve food products, control the temperature of a process, or activate air conditioning.
Optimising the performance of components and their use leads to significant reductions in electricity consumption. In addition to the cold production unit, this also includes the distribution system and the cooling system.
Keeping your company’s cold rooms running smoothly
In food production and related sectors such as catering, sales and gastronomy, respect of the cold chain is essential. Cold rooms are essential for establishments handling large quantities of food. The electricity consumption of this equipment is very high, especially during the summer months. It is therefore crucial to optimise its use.
The approach described below helps to optimise the use of the system.
