Industrial processes require energy, heat and/or cold. Some productions require alternating hot and cold simultaneously. This is notably the case for the food industry - in particular dairy products, meat processing, fruit and vegetables, malting plants, beverages and canning plants - fine chemistry and pharmaceuticals with synthesis cycles or even for the paper industry.
The food industry is known for avoiding any form of waste, especially of raw material. Given the current tension on the energy markets, this is becoming a determining factor not only because of the significant increase in costs, but also because of the threats to supply and the risks of gas cuts in the coming months.
The principle of the cooling units installed on industrial processes is to evacuate heat. This is what allows a component or food to be treated or to lower and stabilize the temperature of a cold room. The evacuated heat is most often lost as in the common systems of air-conditioning which propel cold air in a room while evacuating the calories.
The principle of the heat pump is to recover this heat from the refrigeration systems, raise its temperature so that it can be reused in another part of the industrial process. The use of a heat pump makes it possible to valorize waste heat for industrial processes but also for heat networks.
The objective is to protect against rising energy prices while reducing greenhouse gas emissions and ensuring independence from fossil fuels.
