Cooling is delivered to users (public and commercial buildings, industrial companies, housing, etc.) from a main distribution network connection and transmitted to the building’s secondary facilities via an energy transfer station (ETS). Chilled water is primarily intended for building air conditioning and cooling.
Controlling energy demand
The substation is where the ETS is located, in other words all the devices that transfer chilled water from the distribution network to the user’s secondary network.
The ETS role is to transfer the primary fluid frigories to a secondary fluid (by exchange). It adjusts the flow to regulate the departure temperatures and those of the secondary return to the needs of the various users. The cooling energy and volume consumed are metered at the ETS.
The ETS replaces all the facilities required for the stand-alone production of cold, refrigeration units, pumps, air cooling towers … Since an ETS is more compact than a stand-alone installation, the substitution can therefore be assured in any building already equipped with stand alone system production.
The ETS installed inside customers’ buildings are “connected” and fully automated.
