2 Ventilation KPI ENERGY RECOVERY & HEAT RECOVERY KPI 252E3E-2002E3E PC ART DOUBLE FLOW EXCHANGER Functions Airflows from 250 to 2,000m 3 /h The Hitachi heat recovery ventilation system (KPI) adjusts the temperature and humidity of incoming fresh air to match the indoor environment Low noise level ErP lot 11 compliant fan motors resulting in low noise levels of 24bB(A) Highly-efficient exchanger with the following features: Fresh air supply for indoor environments Energy recovery ventilation between supply and extract air supplies (forced energy exchange mode) efficiencies up to 78% Automatic ventilation (KPI controls which mode to operate within to achieve maximum energy efficiency) Ventilation mode (forced bypass mode). Comfort Over the entire KPI range highefficiency filters (F7) are available. The same applies to consumption from the motors which has halved with values on the 1000 m 3 /h model only reaching 285 W The noise level has also been refined, with the lowest value obtained from the 252 model being 24 db(a). Different static pressures are available in order to meet all the requirements possible. Safety Possibility of fine tuning the CO2 level complements these innovations (sensor not included) All insulation in the KPI range is M1 (NF-P92-501) certified to comply with the mandatory fire-retardant standards issued by ErP (Order of 11th December 2009, Article CH36).

4 Ventilation Functions DX COIL The KPI Active uses a double flow exchanger, with direct expansion coil battery which supplements the air temperature entering the building. This is useful when the temperature outside is low and sufficient recovery is not possible The range consists of 3 models: 1.5 / 2 / 2.5HP with respective flows of 500 m 3, 800 m 3, 1000 m 3 It can be connected to certain units within the UTOPIA and VRF ranges using a monosplit or direct to the VRF.

Once installed on a VRF the maximum output must not exceed 30% of the total output of the unit. Fresh air feed Filters both air incoming and outgoing air. Transfer of heat between the incoming and outgoing air Transfer of moisture in the outgoing air, which reduces the condensation in the air conditioning units and reduces the cooling demand by up to 20% This naturally cools the building with minimum fuel consumption during by-pass mode. The KPI Active is fitted with a celluloid exchanger so that the latent heat is transferred: - in cooling mode: the air humidity decreases, - in heating mode: the moisture in the fresh air increases. This will greatly increase the heat transfer efficiency and comfort. The battery complements and warms the air to ensure the air approaches a comfortable temperature. 207
