Air-cooled Quantum chillers from Engie Refrigeration can now be equipped with heat recovery as well.
This makes it possible to reuse up to 100% of the generated waste heat. The first corresponding Quantum models are now being deployed by an international industrial group from France.
For many years, Engie Refrigeration has been equipping its water-cooled Quantum chillers with heat recovery as an option.
A heat exchanger integrated in the air-cooled Quantum chiller as an addition makes it possible to conduct the heat, which is generated during the cold generation process, to a defined heat process such as heating or the warm water supply. That means an air-cooled Quantum with a refrigeration capacity of 1,300 kW can create a heat capacity of 1,480 kW.
The heat generated during the refrigeration process can be used either completely, or partially in what is referred to as mixed mode. To this end, the waste heat is transferred to a heat circuit via a parallel flooded shell and tube condenser. As the chiller fans are now running at partial load or not at all, this makes it possible to save power and money. At the same time, users take advantage of the thermal energy that is generated anyway, and that would otherwise have to be generated by the heating.
