The following types of air handling can be carried out:
-
fresh air ventilation with high efficiency heat recovery, with possible winter heating or
summer cooling;
-
fresh air ventilation with free-cooling, that is without heat recovery, both in summer and in
winter;
-
air recirculation in winter, with possible heating;
-
air recirculation in summer, with cooling, dehumidification or c dehumidification;
-
air recirculation with partial fresh air ventilation, together with all treatments provided for
during recirculation.
Air flow rate can be set as follows:
-
air supply flow rate from 300 m³/h to 500 m³/h;
-
fresh air ventilation flow rate from 160 to 300 m³/h.
-
free-cooling flow rate from 160 to 300 m³/h.
OPERATION OF COOLING CIRCUIT
COOLING
The finned coil (3), which is connected to the radiant system, enables summer cooling and
winter heating.
The temperature control over the outgoing air is carried out by the machine by means of the
mixing valve in the water circuit.
