CC-RANGE - heat pumps, chillers and combined heat and cooling

The CC-range contains Fenagy’s smallest heat pumps, chillers and combined units. The capacity range is 250-400 kW per unit, available as air-source (heat pump) or air-cooled (chiller) units. The close-coupled heat pumps and chillers are plug-and-play solutions delivered on a steel frame containing the heat pump/chiller in an enclosure at one end and the energy collectors or gas cooler at the other. The close-coupled units are designed to deliver optimal performance in accordance with customer-specific operation needs.

All heat pumps and chillers in the CC-range use the natural refrigerant CO₂, which is ideal for applications with heat-sink return temperatures below 45°C and supply temperatures up to 85°C. The units are working efficiently at any ambient temperature.  A close-coupled heat pump or chiller is a practical solution offering affordable heating and/or cooling and is typically used for industrial applications and communal & district heating.

Offices and hospitals

Easy installation with enclosure

The heat pumps and chillers are designed for easy on-site installation. When close-coupled with the energy collectors or gas cooler, they function as a plug-and-play solution. The frame should be mounted on eight foundation pillars. The enclosure includes lighting, ventilation, a CO₂ alarm and sound-dampening panels. The electrical panel is integrated into the unit, along with waterside pumps, valves and an energy meter.

Control systems

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.
