CHC-RANGE – combined heating and cooling systems

All the heat pumps in the H-range can be delivered in an industrial walk-in enclosure, which is a fully approved machine room with lighting, ventilation, CO₂ alarm and sound dampening panels. The enclosure is available in any colour and with extra space for installation of an electrical supply panel, pumps, valves on the water circuit, etc.

Enclosures are usually delivered with a self-supporting concrete foundation, so only a levelled sand pad is needed on site for the installation.

The complete range uses a standard Siemens PLC controller, and Fenagy has developed its own PLC algorithms for the most essential functions to ensure optimal control and monitoring. Our PLC solutions can communicate with most of the platforms the customer will need to communicate with. The onboard HMI panel offers direct monitoring of the system and its operating conditions. Furthermore, our PLC solutions support several communication protocols and can integrate with the overall SCADA system.

For an air-sourced heat pump, it is essential to have an efficient and robust defrost system that can secure heat production, regardless of weather conditions. Furthermore, unique features have been developed enabling the heat pump to restart automatically after an emergency stop and even after heavy snowfall.

For all systems, Fenagy aspires to minimise start-up and shutdown times, enabling the system to help balance the electrical grid in a future with an increasing demand for such functions. Last, but not least, the system can deliver high supply temperatures, and Fenagy is continuously pushing the boundaries with new functions and features in the PLC development.
