Adaptation and Environment
- Reduced refrigerant charge with low-GWP R-454B, minimizing CO₂ footprint (77% less GWP than R-410A and 31% less than R-32).
- Control of indoor air quality.
- Fully adaptable and configurable rooftops with optional features and a wide variety of installations.
Energy Efficiency
- Inverter technology to maximize seasonal energy efficiency.
- Optimized energy recovery systems for extracted air: Active Inverter Recovery – Dynamic Recovery
- Advanced control to increase seasonal efficiency by optimizing defrost management in the heat pump.
Active INVERTER heat recovery
Innovative Full Inverter Active Heat Recovery System for energy recovery through an additional refrigeration circuit with an inverter compressor.
This circuit allows for an increase in the unit’s nominal capacity, enhancing its compactness.
Additionally, since this extra circuit exchanges heat between the fresh air and exhaust air, under favorable temperature and humidity conditions, it achieves high cooling performance.
As a result, the unit’s nominal performance is improved, and seasonal efficiency is enhanced under partial loads.
Furthermore, the INVERTER technology ensures proper operation at the minimum air flow rates established by the 2021 RITE update, reducing the air flow from 1800 m³/h to 1000 m³/h.
Active Inverter Heat Recovery
Dynamic Heat Recovery
Dynamic heat recovery
It consists of an energy recovery system using an additional exchange coil (subcooler), placed in series with the air-cooled condenser of the unit. This setup significantly improves the unit’s efficiency by reducing the electrical consumption of the compressors.
This system offers advantages over static recovery systems because it avoids higher consumption by supply and return fans due to the high pressure drop associated with plate or rotary heat exchangers.
Additionally, it allows for installation in units with extraction fans.
Systems integration with photovoltaic installations
- Intelligent energy management.
- The ability to manage and adjust optimal electrical consumption and thermal production capacity based on the available photovoltaic generation power at any given moment.
- It enables the integration of rooftops, heat pumps, and inverter chillers with photovoltaic installations.
