The subject of the project is the replacement of two 130 RT Coolant Groups, the installation of a Parallel System and the separation of the primary and secondary networks. The Chillers and the Parallel System are made by the TRANE building company. The hydraulic and electrical installation was completed by AGtech workshops. The Tracer SC Parallelism System allows the reduction of energy consumption in relation to the weather and the changing requirements of the installation, equally distributes the operating hours of the coolers, records diagnostic messages, provides access to all operating parameters of each chiller and allows the installation to be monitored via any Ethernet network from any Web-enabled PC. The Building Maintenance Technicians monitor and control the installation through the Tracer TD7 Touchscreen Graphics Environment, from which the Air Conditioning Programming is performed on an annual basis.
