Energy efficiency and sustainability are currently the most pressing priorities on the European and global HVAC/R market. At ISH 2025, CAREL will be presenting solutions for heat generation and indoor air quality.
Adopting advanced technologies helps optimize system performance, reduce energy consumption and simplify management, while ensuring the highest reliability and compliance with the latest regulations.
Efficiency and sustainability in heat generation
CAREL offers a full ecosystem of technologies for air/water and water/water heat pumps
Heat pumps are a key solution for the decarbonization of buildings, reducing CO2 emissions due to their high energy efficiency. CAREL offers a complete ecosystem of technologies for air/water and water/water heat pumps, including outdoor, indoor, and all-in-one units.
Through the addition of inverters, variable-speed compressors, and electronic expansion valves, these units can adapt their operation dynamically based on actual conditions, optimizing energy consumption and performance.
CAREL’s advanced software
The c.pCO sistema programmable controllers have the task of managing the units, guaranteeing maximum flexibility and integration between system components.
As further support, CAREL’s advanced software ensures optimized management of the refrigeration cycle, with upgraded and improved algorithms such as defrost management, low-load compressor operation, and revised alarm mapping. This software is either ready-to-use or can be easily customized using existing function blocks.
New Stone Virtual Loop tool
The products available are A3 ready and ATEX-certified, designed to ensure safety and faster unit
The products available are A3 ready and ATEX-certified, designed to ensure safety and faster unit certification in applications where flammable refrigerants such as propane are used.
Finally, the new Stone Virtual Loop tool can be used to simulate and test the thermodynamic behavior of units while they are still under development, improving design and reducing validation times in the field.
Digital innovation: Virtual Loop and pYC mini
Innovation is at the heart of CAREL’s proposal at ISH 2025, with two key innovations: Stone Virtual Loop and pYC mini.
- Virtual Loop is CAREL’s simulator that, using digital twin technology, replicates the behavior of actual thermodynamic units in a virtual environment. Integrating seamlessly into the STone ecosystem, this tool revolutionizes the design and testing of units such as heat pumps, chillers, and rooftops, allowing developers to test and optimize the implemented control logic in real time. By eliminating the need for physical prototypes and complex infrastructure, it makes development much faster and significantly less costly, ensuring both high efficiency and reliability of the end product.
- pYC mini is the new line of programmable controllers designed to meet the growing demand for efficiency, safety, and versatility in HVAC/R applications. With a compact structure and the flexibility offered by programmability, pYC mini also complies with the latest regulations on low GWP refrigerants, including flammable gases (A3, A2L). Serial communication, available as standard, is used to directly manage the main actuators on the unit, such as electronic expansion valves, fan speed controllers, and compressor inverters, thus optimizing control and energy efficiency. Wireless connectivity enables quick and intuitive setup using the APPLICA app, simplifying installation and monitoring. Finally, integration with supervisory systems is also available, for constant monitoring and detailed performance analysis.
Indoor air quality and energy recovery
In commercial buildings, the design and efficiency of ventilation systems is essential to ensure healthy, energy-efficient spaces. CAREL develops advanced solutions for energy recovery in air handling units, managed by the k.Air family parametric controllers, covering a wide range of possible system layouts and reducing both times and costs, from design to commissioning.
The thermal wheels for sensible and latent heat recovery ensure both hygiene and no contamination between the different air streams.
Optimal management of air flows in AHUs
When combined with reverse-cycle heat pumps fitted with inverters and electronic expansion valves
When combined with reverse-cycle heat pumps equipped with inverters and electronic expansion valves, part load operation is possible, to reduce energy consumption. Furthermore, continuous indoor air quality monitoring via advanced temperature, humidity, and CO2 sensors allows precise control of air quality parameters.
The offering is completed by adiabatic and isothermal humidifiers that keep relative humidity within a suitable range, as well as dampers for optimal management of air flows in AHUs, improving overall system effectiveness.
IAQ: a speech on how to combine comfort and health
Alexander Willesch, CAREL Sales Manager Ventilation in the D-A-CH-NL area, will give a speech entitled “Indoor air quality: how to combine comfort and health for occupants of buildings”.
The presentation will take place on 18 March, from 11:00 to 11:25 in Hall 12, Level 1, E03, in German. It will focus on the importance of ventilation systems and CO2 monitoring in ensuring indoor air quality, as outlined in the European legislation.
