Close control air conditioners with
Displacement air delivery
PLANT TYPE
THE AIR-CONDITIONING SYSTEM WITH DISPLACEMENT AIR DELIVERY
The air-conditioning system with displacement air discharge is based on the principle that the air is distributed at a very low
speed, while enabling a cooling effect by convection.
This concept has been adjusted and applied by RC GROUP to the air-conditioning of telephone exchanges and rooms where the
concentration of electronic equipment is considerable, in order to maximise and optimise the results that can be obtained in
these specific ambients.
The modern Telecom devices have the aim of heat dissipation by air suction from the lower side close to the floor, and discharging it
from the top. The air circulation in the equipment can be either natural, by convection, or in a forced way, through dedicated internal
ventilation systems.
RC GROUP displacement system creates a cushion of cold air at the floor level, thanks to proprietary COLDLAYER technology, which is
available for all the equipment installed in the room, and can reach also the equipment located in critical positions, thanks to patented
AIRRAIL ® injectors.
Every electronic equipment will “absorb” the amount of cold required to maintain a correct temperature level inside, through a
natural convection effect.
The greater the load inside the electronic equipment, the greater this effect.
So, every electronic equipment uses only the amount required to dissipate its own thermal load, which is generated by maximising the
result and the energy efficiency of the system.
This allows a better and more constant cooling of the electronic equipment ensuring the possibility to meet in real time any load
changes, without any waste of energy.
More than 2000 installations equipped with the RC GROUP displacement system have allowed our R&D division to develop, test and
patent the MISTRAL ® control system.
MISTRAL ® ensures a perfect stratification of the temperatures in the room, as well as a perfect thermodynamic efficiency for the
plant under any working conditions.
MISTRAL ® , thanks to the EFFICIENTFLOW technology, allows the system to adjust itself in real time to any load change, in terms of
quantity and distribution, while ensuring the best energy efficiency.
DIRECT EXPANSION UNITS
Available up to 47 kW cooling capacity and over, these direct expansion air conditioning units are particularly suitable for low and
medium installations, where the compactness of the units and their simple installation are fundamental requirements.
They are available both with remote air cooled condensers and in packaged version with built-in water cooled condenser.
Equipped with Scroll type compressor, characterized by high efficiency and low noise, RC GROUP direct expansion air conditioning units
stand out for the building accuracy, the high reliability and the extreme installation flexibility, thanks also to a wide range of optional
extras that have been conceived to satisfy all demands.
CHILLED WATER UNITS
Similar to direct expansion units, the HEAT HUNTER chilled water air conditioning units are suitable for variable water flow plant
matched to MAXIMO OPTIMIZER liquid chillers series.
The range is very rich with a large number of optional extras suitable for every specific plant demand. The construction quality, the
materials used and the particular care at planning stage of RC GROUP chilled water units, guarantee noise levels among the lowest in
this product category.
