A great deal of information is generated when it comes to operating modern climate control solutions in enclosures. Until now, it has only been practical to record operating hours and the current temperature inside the enclosure.
But with modern devices like the new cooling units and chillers in the Rittal Blue e+ range, a multitude of values and other information can be measured and recorded. This includes the temperatures inside and outside the enclosure, the evaporator and condenser temperatures and, where appropriate, measurements from additional sensors located inside the enclosure.
Instead of a simple operating hours meter, the run-times of the compressor and internal and external fan are recorded separately. There are also system messages, data for capacity utilization and the current parametrization information.
In order to generate added value from the high volume of data, the information must be made available to superordinate systems. To make the seamless communication of data possible, Rittal now offers its new IoT interface, which turns the cooling units and chillers in the Blue e+ range into IoT-compatible devices.
The IoT interface can either be mounted on a top hat rail or directly on the cooling unit or chiller.
The protocols supported are OPC-UA, Profinet, SNMP, Modbus and CANopen. The number of protocols supported makes it is possible to connect to superordinate monitoring or energy management systems in virtually every case. The data from the cooling units and chillers is then available in these systems at all times. It is also possible to set parameters and configure settings via the IoT interface.
The information from the devices can also be used for a wide range of analyses. The communication options available through the new IoT interfaces make it possible to integrate the climate control solutions into IoT applications, paving the way for new applications and smart service solutions.
For example, the options make optimization of maintenance and servicing of climate control solutions possible, lowering operating costs. Another important application is energy data management. With all data available at all times, the level of energy efficiency is increased, which in turn helps reduce costs.
