Classic cooling systems based on refrigerant vapour compression are expensive: they produce cold on demand and consume electricity to do so. For the realisation of efficient cooling systems, we look at the total picture of the production site: measurements supported by calculations and simulations to detail the cold demand at the various temperature levels. We then put together the optimum combination of cooling systems so that the cold can be generated with minimal energy: for example, with free cooling, adiabatic cooling or absorption cooling. With adiabatic cooling, the separation of air and water eliminates the risk of legionella contamination. Only last, we use cooling vapour compression with heat recovery. Of course, we take the necessary buffering into account in the design so that the cold production systems do not become unnecessarily large. An umbrella control ensures that the whole system functions properly. That way, we avoid unnecessary pumping of cooling water, for example.
