Constructive configuration C is equipped with a recirculation air andfresh air mixture chamber, a ventilation section dedicated to supply and a ventilation section dedicated to return/expulsion. Both constructive configurations B and C can be customized with the selection of a flow rate with threepossible values: standard, high, or reduced, based on design needs.EXCLUSIVE OPTIONAL ACCESSORIES OF THE CONFIGURATION BFCB - FREE-COOLING THERMAL VERSION BThe configuration with thermal free-cooling for version B allows operation with a variable percentage of refreshair, with opening or closing of the shutters on fresh air and on recirculation air by means of modulating actuators,which intervene when the conditions of fresh air are such that it allows lowering of the internal thermal loadssimply by placing primary air in the room. Conditions of adjustment are identified by comparing the outsidetemperature with that of the served room. In spring or autumn, or in applications where there are high room loads,the configuration with free-cooling makes it possible to substantially reduce the energy consumption of the unitsand the wear of the compressors.In heat-pump operating mode, the free-heating logic is used. With the same principle as free-cooling, it makes useof the energy contained in the fresh air to increase the thermal load of the served room without the aid of thecompressors.The component requires a system for extraction and expulsion of air from the served room, outside the unit (to be provided by the client).FCEB - FREE-COOLING ENTHALPIC VERSION BThe configuration with enthalpic free-cooling for version B allows operation with a variable percentage of refreshair, with opening or closing of the shutters on fresh air and on recirculation air by means of modulating actuators,which intervene when the conditions of fresh air are such that it allows lowering of the internal thermal loadssimply by placing primary air in the room. Conditions of adjustments are determined by the comparison not only ofthe temperature but also of the humidity between the exterior and the served room.The component requires a system for extraction and expulsion of air from the served room, outside the unit (to be provided by the client).SERM - ON/OFF MOTORIZED AIR OUTLET DAMPEROpening or closing of the fresh air shutter is controlled by an ON-OFF actuator which, with the machine running,opens the shutter to a preset value while, with the machine shut down, closes the shutter, thus avoiding the"chimney effect" of the ducts with heat loss to the exterior.SERMD - MODULATING MOTORIZED FRESH AIR SHUTTERThe configuration with motorized shutter with modulating adjustment for configuration B allows operation with avariable percentage of refresh air with opening or closing of the shutter by means of an actuator driven by a 0-10Vsignal based on concentrations of CO2 or CO2+VOC detected by the air quality probe. This configuration can beselected only in combination with the air quality probe.30
