The primary network of the CEA in Saclay was balanced using the EQUILOG(*) method during the 2018/2019 heating season.
(*) Method of balancing by homogenisation of return temperatures, patents for condominiums belonging to the company Mapsec http://mapsec.fr and the Ministry of National Education.

The need for the primary network balancing operation at CEA Saclay arose from the connection of a new 2.2 MW substation.

The network supplies 89 exchangers distributed across 81 substations, for a total installed capacity of 88 MW. It is supplied from a combined heat and power plant.
69 heat exchangers exclusively supply radiator circuits and air handling units at a nominal temperature of 80/60 °C.
→ 25 heat exchangers partly supply floor panels at a nominal temperature of 50/40 °C.

The substations are equipped with plate heat exchangers. The temperature control at the secondary outlet of the exchangers is carried out by two-way control valves installed on the primary side of the exchangers.
