Carel shares solutions at Chillventa

Carel recently shared its products and solutions for energy-efficiency and improved refrigeration system performance at the Chillventa HVAC&R exhibition held in Nuremberg, Germany in October.

DC technology and complete unit management

Among its presentations, Carel shared its proposal for centralised systems based on DC technology applied to both condensing units (Hecu solution) and units with rotary compressors (multi-DC solution).

Synchronised operation of the variable-speed BLDC compressor with the inverter and the electronic valve allows continuous modulation of performance, meeting the load requirements of every refrigeration unit while adapting to specific daily and seasonal variability.

“For commercial refrigeration applications, complete unit management is ensured by the MPX and Heos solutions, electronic controllers developed to guarantee stable unit control temperature and integrated operation of modulating devices,” says Carel. “All these controllers offer a high level of certification, making them suitable for incorporation into units that use flammable refrigerants, such as A3s.

“Embedded NFC and Bluetooth connectivity respond to the need for extended and simplified usability, through the use of apps developed specifically for interaction with the unit.”

A new controller for compressor racks

According to Carel, connectivity revolutionises the way technical personnel and users interact with refrigeration units, and all the functions used by the control system to manage a reliable and efficient compressor rack also need to be available remotely.

Carel’s uRack controller was developed to meet all these needs of compressor racks, says the company, improving performance through interaction with the Applica mobile app and connection to Carel supervisory systems for remote monitoring and performance optimisation throughout the system life-cycle.

Increased efficiency through support for installers in the field

While at Chillventa, Carel also shared its aim to revolutionise traditional “cold chain” installation, commissioning and maintenance practices by making troubleshooting and configuration in the field extremely simple, fast and above all connected.

For this, the company recommends its new iJW refrigeration controller, combined with the Applica app, to ensure smart and intuitive commissioning for the main commercial refrigeration applications.

Meeting reliability demands in scientific applications

Temperature stability and traceability, reliability and effective alarm management are specific requirements for medical-scientific refrigerators. Carel says its extended portfolio of connected controllers offers simplified interaction through apps and IoT cloud services.

Specifically, the company says its iJS controller was developed to ensure that the products are stored in the units in the best possible way, and preserved in compliant conditions. Distinctive features relevant to medical-scientific refrigeration applications include reliable temperature logging, display of the minimum and maximum temperatures reached inside the unit, and automatic management of optimisation procedures (exploiting the connectivity options).
