In conclusion, the DNC device, unlike all other traditional sound control devices, whilst reducing the noise emissions, is able to ensure the highest relative efficiency. Though it reduces the performance of the unit, the cooling capacity remains unchanged, ensuring constant operation and high reliability. The DNC is designed to be installed also on existing units and for any kind of application. The system consists of a microphone and sound processing system mounted on the chiller or at a suitable remote location from the chiller (say, in the direction of residential buildings), and is linked and integrated into the chiller controls. This is a very important aspect that helps to ensure precision and reliability to the entire plant. Remote Control Camera device allows access to the camera menu from the surface through 30m cable with real time settings adjustment POWER MANAGEMENT The DNC-HD6 set is surface powered allowing unlimited operation time with wide voltage ranging from 12V to 24V (depending on External cable length). The DNC is also able to identify the noise source and “understand” if it is generated by the chiller or by any external source. The main difference between DNC and other systems consists in the fact that with the Dynamic Noise Control what must be set are only the noise limits, and not the performance levels: it is the DNC that regulates the fan speed, reducing the performance in order to fall within the highest permissible noise level. To follow along with the example, you will also need a running instance of the Connectware. To understand the basic concepts of the Connectware, please check out the Technical Overview lesson. The system constantly measures the noise produced by the chiller and is able to “adapt” the chiller performance in order to not exceed the noise limits set for different time slots. Prerequisites This lesson assumes that you want to integrate a Heidenhain controller using the DNC interface protocol with the Cybus Connectware. The DNC is designed to avoid this problem: it is designed to be “smart”.
