Borealis ACE: autonomous reversible heat pump for primary air treatment (100% outdoor air) with dual energy recovery: crossflow static recovery plus refrigeration recovery, equipped with inverter compressors for constant temperature supply.<\/p>\n

Structure made with anodised aluminium profiles with thermal bridge break and removable sandwich-type closure panels, consisting of two lacquered galvanised steel sheets with a PIR thermo-acoustic insulation core, 45 mm thick as standard. Interior of panels lacquered. Stainless steel condensate tray. Refrigeration unit equipped with scroll inverter compressors as standard. Coils made with copper tubing and corrosion-resistant aluminium-magnesium alloy fins.<\/p>\n

Standard EC plug-fan fans with integrated pressure and flow regulation in the unit\u2019s control system.<\/p>\n

High-performance air-to-air static heat exchanger made of aluminium with Eurovent certification. Electrical panel with phase sequence detector, thermal-magnetic protection, and circuit breakers for each motor, phase sequence detector.<\/p>\n

Standard filtration: G4 in extraction and outdoor air intake. Optionally, high-efficiency filters.<\/p>\n

Proportional communicable control with IP and MODBUS connectivity. Communication gateways to other BMS available on request. Proprietary programming with periodic updates available. Optionally, on\/off control.<\/p>\n

ACE units are standalone systems, meaning they do not need to be connected to chiller or boiler water pipes or refrigerant lines. They come with their own control system and can be installed on rooftops or indoors.<\/p>\n

Their complete independence and high efficiency make them suitable for working alongside any main climate control system, from boiler and radiator heating to variable refrigerant flow systems.<\/p>\n

When designing a project with primary air units, it is essential to keep the supply temperature as constant as possible to avoid discomfort for users. If the primary air unit is not inverter-equipped, the supply temperature will vary significantly as the compressor turns on and off to meet the setpoint temperature. For primary air units, these variations can be broad and abrupt, and they occur out of sync with the operating mode of the machine; for example, when the compressor is off in winter, the supply temperature drops, and vice versa.<\/p>\n

To prevent this effect, Borealis equips the ACE units with inverter technology in the compressors as standard. This allows very precise control of compressor power, avoiding fluctuations and maintaining a constant supply temperature, reducing operating costs as well.<\/p>\n

Optionally, ACE units can be equipped with condensation heat recovery systems, capable of recovering between 10% and 100% of the unit’s cooling capacity. This recovered heat in summer mode can be used to preheat DHW at no additional cost, and as residual energy, it allows for a reduction in the size of the building’s renewable energy production system (solar, etc.).<\/p>\n

The regenerative refrigeration system, in which the air-to-air heat exchanger is combined with the refrigeration system, recovers a large portion of the energy from the exhaust air, making it much less affected by extreme temperatures than other refrigeration systems. This results in top-tier performance (SCOP, ESEER).<\/p>\n

The autonomous ACE units for primary air come with iPro control as standard, programmed by Borealis for this specific application. iPro is hardware manufactured by the Emerson Group with proportional control and integrated IP and MODBUS communication. It includes a web server with a page where the machine\u2019s operating parameters can be viewed and modified. It can be connected directly to the building’s router, requiring only the connection cable, and monitored from any computer or mobile device (phone, tablet, etc.)<\/p>\n
