AIR CONDITIONING SYSTEM WITH DISPLACEMENT AIR DELIVERY
The basic concept of the air conditioning system with displacement air delivery is based on
the natural convection principle, where the cold air is at the lower ambient zones, while the hot
air is at the higher ones.
This concept has been developed and applied by RC GROUP for the air conditioning in
Telephone Exchangers and Hi-Tech. facilities.
The modern Telecom devices have the aim of heat dissipation by air suction from the lower
side close to the floor, for discharge from the top side.
The air circulation inside the Telecom device can be in natural convenction mode or through
internal fans.
The RC GROUP free-cooling air conditioning system with displacement air delivery supplies
the cold air directly into the room close to the floor with extremely low air speed and intakes
the air from the top side of the conditioner where the air temperature is higher.
Therefore, the Telecom devices intakes the cold air from the bottom and discharges the hot
air from the top.
The system and the extremely low air speed, causes a high air stratification with 10°C
temperature difference between the coldest and the most hot zone. For example we can
consider a temperature condition of 22°C close to the floor and 32°C close to the ceiling with a
mean temperature of 26°C at 1,7m height from the floor.
By hot air suction in the higher ambient zone, the air conditioner remarkably increases both
the thermodynamic performance and the efficiency, with consequent working conditions and
energy consumption optimization.

RC GROUP S.p.A. ● T_HH_1112_GB ● R410A
ENERGY SAVING (FREE-COOLING)
For an energy-saving, the RC GROUP conditioners are equipped with a proportional
automatic free-cooling system in order to obtain free cooling when the indoor temperature is
higher than outdoor one.
Practically, the fresh air is used as coolant, when the outside conditions allow for this, in order
to cool the ambient.
The cooling system is fully proportional and allows three working mode type:
total free-cooling: only fresh air is used to cool the ambient
partial free-cooling: the fresh air is used for a pre-cooling and the compressor is used
to balance the load.
mechanical cooling: the compressor is used to cool the ambient.
The fresh air put in the ambient causes an internal pressure increase, that must be avoided to
grant a correct performance of the plant.
For this reason it is necessary to install an overpressure damper close to the ceiling, to allow
the hot air discharge.
Please note the overpressure damper, necessary for the correct running of the plant, placed
at the opposite side of the air conditioner close to the ceiling.

IMPORTANT
For the axial and centrifugal fans, the current nominal values have been considered
equal to the data plate values. For this reason, the nominal current and the data plate
current is the same.
Actually, the real absorbed current is normally lower than the data plate value.
These values depend on the unit working conditions and on the type of control of the
plant.

MISTRAL CONTROL LOGIC
The HEAT HUNTER air-conditioners are controlled trough the patented MISTRAL
(Modulating control of Indoor STRAtification Layer) control logic.
Since the engine of a displacement system is the difference between the air temperature
close to the ceiling and close to the floor (room Dt), for a correct plant working condition this
difference must be the same in every working conditions.
The system controls the room air temperature. The humidity control is optional.
THE ROOM AIR TEMPERATURE CONTROL
The room air temperature control is obtained by three different measured temperature:

conditioner air intake temperature

room temperature close to the conditioner (with additional sensor)

conditioner air delivery temperature
The room temperature corresponds to the mean air temperature at 1,7m height from floor in
the racks corridor.
The control logic foresees that the conditioner air delivery temperature is controlled through a
variation of the conditioner air flow, keeping the room Dt constant.
The temperature is controlled through the conditioner air intake probe, it activates the
compressor when the temperature rises.
The conditioner air delivery probe controls the supply fan speed between 75% and 100%, to
maintain the air delivery temperature set-point.
With compressor off the air flow is automatically reduced to 30% of the nominal air flow.
ADDITIONAL TEMPERATURE SENSOR
Each conditioner can be wired to an additional probe to measure the room temperature in a
determinate point of the room.
These additional probes must be used only if strictly requested.
We suggest two types of usage:

The presence of a highly temperature sensitive device and/or with a thermal load higher
than the average. In this situation the probe should be placed close to the device and
wired to the nearest conditioner.

Some particular situations of the room lay-out.
The additional probe compensates the compressor set-point, increasing or decreasing it, to
keep the air temperature set-point where the probe is installed.
On the contrary, with room temperature lower than set-point, the control is made by
temperature measured by conditioner as previously described.
THE ROOM RELATIVE HUNIDITY CONTROL
The room relative humidity control takes place only if the conditioner is equipped with the
additional Relative Humidity probe.
When the relative humidity exceeds the set-point, the control decreases the air delivery
temperature set-point. This reduction causes not only an automatic air flow reduction and an
increase of the differentials set-point, but also a lower relative humidity of the air delivery, able
to increase the latent heat and to correctly dehumidify the room.
ADVANTAGE OF THE MISTRAL LOGIC
The MISTRAL control logic allows two types of advantages.
The first advantage regards the temperature gradient in the room where the air-conditioner
has been installed.
Within the air-conditioner’s range of operation, i.e. when the capacity delivered by it is greater
than 0%, thanks to the patented MISTRAL control logic, the gradient is equal to the designed
value.
18
RC GROUP S.p.A. ● T_HH_1112_GB ● R410A
On the contrary, with the traditional control logic, without modifying the air flow, the gradient
decreases and its values prevent the correct operation of the system, because the
displacement principle cannot work well if the differential temperature values are too low.
TEMPERATURE GRADIENT

CARICO

Area for a correct performance of the Displacement system
The other advantage is connected with the power consumption of the fans, of the variation if
the air flow depends on a variation in the fan’s rpm.
With the traditional system the ventilation capacity is always at its peak, regardless of the air
temperature in the room (and accordingly, regardless of the capacity required by the system).
When using the system patented by RC, the capacity decreases considerably according to the
room temperature (i.e. the capacity required by the system).
This decrease is different according as the fans are supplied through Inverter or phase-cut
electronic regulator.
Thanks to MISTRAL control logic, it is possible to obtain the best energy savings in every load
conditions, even at 100%. Indeed, in a plant with two Heat Hunter air conditioners (Master and
Slave), it is more convenient to have both conditioners working at 50% than only one working
at 100% of the load.
With both conditioners working at 50%, the supply fan power input for each unit is the 12,5%
of the maximum.
In this way 75% energy saving in supply fans power input is achieved.

AIR-RAIL PATENTED AIR-DISTRIBUTION SYSTEM
The AIR-RAIL distribution system can create an "adhering vein of air", so as to "guide" the air
flow by induction and to convey it where it is actually needed, and thus preventing any bypass phenomena after the collision between the air flow leaving the air-conditioner and the
racks.
The formation of the adhering vein is essential, because the displacement distribution, due to
the low speed, does not produce any induction effect. The flow is properly distributed where
there is enough space, but encounters a few problems when the distance between the airconditioner and the rack is limited.
The base of the unit is provided with a series of nozzles that can be capped, where only a
minimum percentage (< 10%) of the air moved by the air conditioner can flow.
Patented AIR-RAIL system
Nozzles
This air forms an adhering vein, at the floor level, that can pull the displacement air flow by
induction.
In practice, this vein makes it possible to convey the air in a proper way, like a sort of rail,
preventing the air from hitting the racks.

Nozzles are fitted uncapped while the unused nozzles have to be capped.
In this way, if the air is pulled towards the corridor, the adhering air vein releases, by
induction, some space where the leaving air is conveyed on the side of the displacement
diffuser above the capped nozzles.

OPTIONAL ACCESSORIES – PLENUM WITH FREE-COOLING DAMPER
The plenum allows direct free-cooling, which is a direct fresh air put into the room through the
air conditioner.
The optional has the same dimensional and constructive characteristics of the conditioner and
is placed on the upper side of the unit.
A two-way damper controls the outdoor and return air flows through a proportional servomotor
directly driven by microprocessor.
The cooling system is fully proportional and allows three working mode types:

total free-cooling: only fresh air is used to cool the ambient.

partial free-cooling: the fresh air is used for a pre-cooling and the compressor is used to
balance the load.

mechanical cooling: the compressor is used to cool the ambient.
COMPONENTS:

Housing made of galvanized steel sheet inner frame that includes gaskets for air
tightening.

Panels in galvanized steel sheet externally coated with PVC film. Panels are internally
insulated by noise absorption material (self-extinguish class 1) and are fixed with screws.

Two-way damper (fresh air and return) in galvanized stell sheet with steel pins rotating on
nylon brushing.

Proportional servomotor directly driven by microprocessor.

Terminals for servomotor electric connection to the unit.
The servomotor electric cable is contained inside the unit electric board.

OVERPRESSURE DAMPER – (Unit with fresh air kit)
For a correct performance of the plant it is necessary to install an overpressure damper close
to the ceiling.
The damper must allow air exhaustion when air conditioners work in Free-Cooling mode. The
fresh air put in inside the ambient causes an internal pressure increase, that must be avoided
to grant a correct performance of the plant.
