Marseille: District cooling and heating in combination with geothermal energy
Industry:
District and local cooling networkTwo QUANTUM chillers, which draw their energy from geothermal energy and other sources, supply end users in Marseille with district heating and cooling.
-
The two QUANTUM P455-E7I-78 chillers have a total cooling capacity of eight megawatts; a total cooling capacity of 16 megawatts is planned for the second construction phase.
-
With this project, ENGIE Refrigeration is combining district cooling, district heating and geothermal energy in a single concept.
For the first time, ENGIE Refrigeration is generating district cooling and district heating in combination with geothermal energy using seawater in France - thus securing the supply of numerous end consumers in Marseille. Two QUANTUM chillers with a cooling capacity of eight megawatts are used for the production of district cooling and district heating in combination with geothermal energy. These are to be doubled to a total output of 16 megawatts in the second construction phase.
The perfect trio: district cooling, district heating & geothermal energy
In addition to the future-proof energy concept of district cooling, district heating and geothermal energy, those responsible on the customer side were particularly impressed by the high energy efficiency of our systems. The EER (Energy Efficiency Ratio) value is 5.71 at full load and 13.54 at partial load. The simplified maintenance of the solution for generating district cooling and district heating using geothermal energy was also a key decision criterion. Due to the recooling with seawater, the QUANTUM chillers used are designed to be corrosion-resistant. Our cooling and heating specialists equipped the internal condenser tubes with automatic brush cleaning. The "Cool Care" remote maintenance solution developed by ENGIE Refrigeration helps to record the chiller data continuously and on a large scale. As a result, the customer ultimately benefits not only from reliable district cooling and heating in combination with geothermal energy, but also from excellent service.
