A visitor to ARBS 2018 could be forgiven for thinking that Carel did not need to set up its own stand.

Nowadays, just about every other stand displaying refrigerating units appears to be utilising Carel products as the control component.

Since appearing on the Australian market in 2001, environmental sustainability and energy efficiency along with usability and connectivity were at the centre of Carel’s offering.

A new focus, for the international controls company, was on show at ARBS 2018.

Carel is now focussing on utilising the advantages of the internet to increase the connectivity component of its range.

Known as the Internet (or Intelligence) of Things (IoT), the connection of its products over the internet allows unit interaction through the use of cloud services.

Now, not only can users maintain full control over their refrigeration and air conditioning units, the units themselves can also communicate and connect for the best option in energy efficiency.

It’s a new experience in interacting with units, from users in the field to managers in the office, all via cloud services.

New data processing technologies combined with CAREL’s thermodynamic expertise are integrated into the cloud portals to provide users with useful information to make everyday activities easier and more effective.

The useful data are in fact collected and presented on dashboards for energy managers, service teams and quality departments. Specific views are customised for marketing managers and property managers, for different applications.

Data from the field are processed using the latest machine learning technologies, applying predictive models for the development of new predictive maintenance services and performance optimisation.

To help the user and the technician, Carel have introduced its Applica app. Configuration and optimisation of unit set-up are made simple and intuitive by the combination of smartphone application and web portal, allowing configurations and graphics to be managed flexibly and always kept up-to-date.

The best example of the potential of what Carel controls can provide is the use of its DC technology in the DC-3 unit introduced by Actrol and displayed just down the hall at ARBS 2018.

The DC-3 utilises Carel’s DC inverter technology to bring high efficiency to the common cool room market. Promising power consumption reductions of 40 per cent coupled with fine temperature control, the Carel controllers provide constant optimisation reacting to ambient operating conditions to maximise compressor performance and longevity.

As the use of intelligent electronic expansion valves continues, Carel recommend the use of its µChiller solution for air/water and water/water chillers and heat pumps. Integrated management is the key to the µChiller connecting the EEVs and brushless DC compressors. 

Other products on show at ARBS were MPXone, Carel’s latest controller for food retail refrigeration units that, for the first time in the sector, revolutionises human-machine interaction through direct connectivity with mobile devices via Bluetooth® and NFC; also k.water and k.air, the new range of products for integration, control and monitoring of HVAC systems.

Carel also exhibited boss mini, a system supervisor for any system from commercial refrigeration to datacentre cooling and even light commercial HVAC.

Mini boss follows on from the success of its big brother, boss but retains the same usability and connectivity features but in a more compact footprint.

The range of EmJ modulating ejectors at the show extends the concept of continuous modulation to small and medium applications for all transcritical CO2 systems.

Through the introduction of its pR multi DC this controller is able to manage multiple DC compressors on the same line.

With its precise continuous modulation the EmJ ejectors ensure maximum efficiency during different operating conditions at all times, adapting to system requirements especially at part load.
