OUTDOOR 5°C NEW HEAT RECOVERY 5°C CONTROLLED MECHANICAL VENTILATION UNIT Extracted from: THE INSTALLATIONS AND THE SPREAD OF THE SARS-COV2-19 IN THE WORKPLACE, document drawn up by the Italian Association Air Conditioning, Heating and Refrigeration www.aicarr.org – info@aicarr.org. For 70 seconds Ghost extracts to the outside the hot and stale air present in the room. By crossing the duct the air releases its thermal energy which is accumulated by the ceramic exchanger; at the end of this cycle the fan reverses the direction of rotation and starts the input cycle for another 70 seconds. The outdoor fresh air, passing through the hot ceramic exchanger, recovers the thermal energy and is introduced into the room at a more comfortable temperature. This allows to achieve significant energy savings, as it prevents the heating system from operating at maximum intensity as would happen in the event of air exchange by opening the windows. PRINCIPLE OF THE DECENTRALIZED RESIDENTIAL VENTILATION The thermal energy is collected in a ceramic exchanger as long as it reaches the maximum capacity. Every 70 seconds the fan reverses the direction of the rotation alternating air extraction and air intake cycles. Ventilation and risk of infection Considering that the external air is not normally contaminated with the virus, AiCARR recommends a constant ventilation in the environments without any mechanical ventilation equipment installed; where the ventilation system is present supplying fresh air inside, AiCARR suggests to keep it on all the time, (24 hours a day, 7 days a week) and make it running at the nominal speed or maximum speed allowed by the system to remove the particles in the air (aerosol) and reduce the deposition on the surfaces. The mechanical ventilation and air filtration are possible through dedicated systems (only ventilation) or air conditioning systems (mix primary air and all-air plants); the dilution with external air and high efficiency filters reduce the presence of particulates and bio-aerosols thus helping to decrease the risk of infection. For 70 seconds the fan extracts the hot and stale air outwards IT SANITIZES THE AIR For 70 seconds the fresh outdoor air crosses the exchanger, it is pre-heated and introduced as new air into the room. Then the extraction cycle is reactivated. O.ERRE EP S.p.A.

DECENTRALIZED HEAT RECOVERY UNIT ALTERNATE FLOW DISPLAY REMOTE CONTROL GHOST is the perfect solution to grant a proper mechanical ventilation in homes and business premises, in case of renovations and in all situations where a ducted system cannot be used due to space reasons. Ghost is easy to install and has a modern and sleek design. This means that the fan can blend seamlessly into any environment. It can be quickly installed on 160mm ducting. The airflow covers 60 m3/h both for air extraction and intake, thus ensuring an adequate ventilation also in high-sized rooms. The alternate flow...
