- New Concept: Diehl Controls Offers Base Products Customized to Customer Requirements
- Highly Efficient Technology: High Efficiency and Optimal Control
- Setting New Standards in Efficiency and Environmental Friendliness of Heat Pumps
Nuremberg/Wangen, 08.10.2024 – Diehl Controls is making its debut at the “Chillventa” trade fair in Nuremberg, presenting a new power package for heat pump manufacturers. The product bundle consists of an inverter with award-winning technology, a controller unit, and modular components such as a Human-Machine Interface (HMI) display. These predefined base products are finally customized according to customer requirements. The advantages for the customer are obvious: not only can they receive high-quality, tried-and-tested products; thanks to a modular approach, they can enter the market more quickly.
The core of the power package is the inverter. It offers efficiency-optimized control of compressors in air conditioning units and heat pumps for single or three-phase grid connections, covering an electrical power range from 2 kW to 11 kW. The fully integrated active power factor correction (PFC) maximizes the active power intake from the grid and eliminates reactive power losses, reducing the load on the power grid. The single-phase inverter uses the innovative Smart-Current-Path (SIP) topology, reducing conduction losses by 20%. In combination with wide-bandgap (WBG) semiconductors such as silicon carbide, the total losses of the frequency converter can be reduced by up to 50%.
Other features of all inverters include an integrated EMC filter to reduce electromagnetic emissions, data tracking and storage for system monitoring, as well as motor protection and functional safety against overpressure, overtemperature, and overcurrent. These and other functions were developed by Diehl Controls and tested, among other things, in their own EMC absorber hall. The inverters also meet the necessary safety requirements for use with A2L/A3 refrigerants such as propane.
Thanks to this innovative technology, Diehl Controls is setting new standards in the efficiency and environmental friendliness of heat pump components.
Precise Algorithms and Efficient Energy Consumption
Diehl Controls has developed software specifically designed for heat pump applications. This software is the basis for providing a control function with final hardware and software customisations on a modular basis according to customer requirements.
Thanks to precise algorithms in the controller, the heat pump operates with maximum efficiency, reducing energy consumption and operating costs. Like the inverter, the application software has been continuously further developed. Comprehensive safety functions, such as overheating protection, refrigerant leakage detection, and pressure monitoring, ensure safe operation of the system.
An innovative HMI solution completes the product range. The 4-inch color TFT display is equipped with touch functionality, with additional touch buttons and a rotary knob available as options. Modular sensor options enable intelligent interactions and independent control loops.
The HMI solution supports wired and wireless communication, automatic detection and self-networking as well as WiFi and Bluetooth connectivity for remote control and over-the-air updates. This allows the customer to display the status of the connected components or realise other control functions on their mobile device at any time, for example.
