ROOFTOP – PERSEA EVO KCRA

Adaptation and environment

• Reduced charge of low-GWP refrigerant R-454B minimizing CO₂ footprint (-77% less GWP than R-410A and -31% less than R-32).
• Indoor air quality control
• Fully adaptable and configurable roof-tops with a wide variety of optional and mounting options

Energy Efficiency

• Inverter technology to maximize seasonal energy efficiency
• Optimized exhaust air energy recovery systems: Inverter Active Recovery – Dynamic Recovery
• Advanced control for increasing seasonal efficiency by optimizing heat pump defrost management

Recuperación Activa Inverter

Innovative Full Inverter Active Recovery System for energy recovery by means of an additional cooling circuit with inverter compressor.

This circuit allows an increase of the nominal power of the equipment, which increases its compactness.

Moreover, since this additional circuit exchanges heat between the fresh air and the extract air, under favorable temperature and humidity conditions, a high cooling performance is obtained.

This increases the nominal efficiency of the unit and the seasonal efficiencies under partial loads.

Furthermore, due to the INVERTER technology, they ensure the correct operation for the minimum flow rates established by the RITE update in 2021, going from an air flow rate of 1800m³/h to 1000m³/h.

Recuperación Dinámica

Consiste en un sistema de recuperación de energía
mediante una batería de intercambio adicional
(subenfriador), colocada en serie con el condensador de
aire del equipo, consiguiendo una mejora importante de
la efi ciencia del equipo al reducir el consumo eléctrico de
compresores.

Este sistema es ventajoso frente a los sistemas de
recuperación estática, porque evita un mayor consumo
de los ventiladores de impulsión y retorno, por la elevada
pérdida de carga de dichos recuperadores de placas o
rotativos.

Además permite su instalación en unidades con ventiladores
de extracción.

Integration systems with photovoltaic installations
