CLIMMA MISTRAL 750
The Italian company Veco, internationally known for its
products strictly linked to the nautical world, such as
the Frigoboat refrigerators and the Climma air-
conditioning systems, now presents the new modular air
conditioner called the Mistral 750. The characteristics
of this modular system consist in the possibility of
setting it up to meet personal requirements, since it
has one main unit and a series of fan coils for cooling
each individual room. Usually marine air-conditioners
always work on the same air contained in a specific
environment, with the inconvenience that recycling
involves change of air being entrusted to any opening
of doors or portholes. So every time a door or porthole
is opened a large quantity of humidity enters internal
areas to the detriment of comfort and well-being.
The Climma Mistral 750 operates in a different manner
compared to standard air-conditioners. Air is taken
from outside, dehumidified, taken to the neutral
temperature of +22° C and then introduced into the
room. Two stages form the dehumidifying process,
however the main stage consists in passing the air
through a finned heat exchanger linked to a
refrigerating circuit, in which pre-cooled water
circulates and that is then also taken to a neutral
temperature of + 22° C. The system also includes a
proportional valve that regulates the passage of water
as it enters, thereby guaranteeing the air's constant
temperature in the initial stage. As it is released,
however, the air's temperature is maintained constant
by a resistance coil modulated in the PWN system. The
air is distributed through a series of coils in the
desired premises without those unpleasant temperature
variations that usually characterise non-modular
systems. Thanks to this new system and to the correct
positioning of channelling and fan coils, it is
possible to create environments, even on large boats,
that are comfortable and free from stale air, allowing
both temperature and humidity levels to be monitored
and modified at pleasure. The Mistral 750 technical
specifications include a capacity of 45,000 Btu/h, air
capacity equal to 750 mc/h.
