DEHUMIDIFICATION AND COOLING
The finned coil (3) supplied with the water coming from the radiant system, cools down the air,
while the cooling evaporator (4) performs further cooling and dehumidification.
The refrigeration circuit is made up of two condensers connected in parallel: in addition to the
an air-cooled condenser (5) a second condenser is cooled by the outgoing air flow (6), thus
releasing the condensation heat outwards. In carrying out this process the machine uses both
exhaust stale air and an additional air flow coming from outside.
The two electronic expansion valves (E) allow to distribute the condensation heat between in
the incoming and outgoing air in the desired proportion; this enables to have outgoing air at the
desired temperature between maximum cold and neutrality.
The levels of outgoing air temperature that can be set are:
-
neutral summer temperature;
-
summer cooling temperature;
-
neutral winter temperature;
-
winter heating temperature.
PLEASE NOTE: the cooling system cannot be started up during winter or in fresh air ventilation
mode only.
