grounded and in accordance with the relevant
regulations. There is a label on the body or the
electrical panel indicating the grounding location of
the unit.
5.5. Air Conditioning Unit
Installation and Connection
Since the room where the air conditioning unit will
be installed is a wet place, it should be kept in mind
that the floor should be waterproof and drainage
measures should be taken. To avoid any problem in
the operation of the unit, the concrete base of the
device should be made smooth and in balance.
5.6. Drainage
A drainage system should be used at the drain outlet
of the unit to ensure a constant flow of water from
the drainpipe of the air conditioning unit.
Proper drainage application is important in order to
avoid air suction or leakage from the drain to the unit
and to discharge water inside the unit without
overflowing. In drainage dimensions, the static
pressure in the area where the drainage will be
applied should be taken into account. AIOLOSAIR IS
NOT RESPONSIBLE FOR FAILURES CAUSED BY
WRONG DRAINAGE USAGE.
Negative pressure drainage
At the pipe outlet of the condensation pan, the
minimum distance from the lower point of the pipe
to the floor, D [mm] is calculated with the following
formula:

 󰇟󰇠
P [Pa]: It is the negative pressure in the device and
the pressure value here should be used within the
absolute value.
Positive pressure drainage application
P [Pa]: It is the maximum pressure in the cooling coil
and H1 is calculated by the following formula:

 󰇟󰇠
H2= 50 mm
The inside of the positive pressure drainage must be
filled with water before the device is put into
operation, and the negative pressure drainage can
only be used in negative pressure drainage outlets.
If negative pressure drainage is not supplied from
the factory should be made according to the figure
below.

INSTALLATION AND OPERATION MANUAL HYBRICOOL FLAT-V

5.10. Cooling Coil
i. Check the connections based on the sizing
projects and check the leakage and
tightness of the connections.
ii. If fins are damaged during the
transportation, fix them.
iii. Check if the drop eliminator behind the
cooler is properly connected.
iv. A substance that blocks water flow should
not be put into the ceiling.
v. Check that the condensed water is
drained, and the drainage is working after
a while after the cooling coil is switched
on. If necessary, clean the drainage.
Attention: In coils where water is used as a
refrigerant, against the possibility of freezing
at temperatures below 0°C, no water should be
left in the circuits to prevent damage to the
coils. If water is to be left, glycol must be added
at a rate that is safely calculated according to
the lowest possible air temperature. AiolosAir
is not responsible for water freeze damage
caused by failure to take precautions.
5.11. Adiabatic Cooling System

make sure that distilled, dirt-free and
demineralised water is supplied to the
system.
ii. Adiabatic module water inlet pressure
min. Check it is 3 bar.
iii. Check the water nozzles.
iv. Make sure that the air-tight heat
exchanger cover is tightly closed and
airtight.
v. Before the device is started, check that the
adiabatic module drainage drain is made
properly with proper drainage and pipe
connection.
Attention: When switched into winter
operation, the remaining water in the
adiabatic cooling module pipes must be
drained. For this, it should be checked that the
solenoid valve on the adiabatic cooling module
water supply is open and the water flows
through the pipes in reverse flow. AiolosAir is
not responsible for any damage caused by
failure to take precautions.

5.14. Control System
5.14.1. Operation
Scenarios
HybriCool Flat-V air conditioning units work at
maximum capacity in accordance with the
ready prepared scenarios via room controller.
General Operation Scenario
The general operation logic of AIOLOS AIR
HybriCool Flat-V vertical type air conditioning
unit with 100% fresh air and adiabatic cooling
system is described below:
IEC Operation System
High efficiency counter-flow heat exchangers
are used in HybriCool series. So, the heat
exchange will proceed at the highest level.
This heat exchange begins with the saturation
of exhaust, return, air right before entering the
heat exchanger. Fresh air, which passes through
heat exchanger and saturated return air make
heat exchange via lamella of heat exchanger
without physically mixing each other in
accordance with the thermodynamically. By this
way, the inlet air is cooled in summer and
heated in winter.
DX+ Heat Pump Operation System
Compressors with high COP values are used in
HybriCool series. So, the highest cooling
capacity with the lowest energy consumption is
provided.
A main factor in DX system is room
temperature. Operation systems of
compressors are depended on firstly room
temperature, then the set value of room
temperature. They keep working on the same
logic both summer and winter seasons.
Summer operation mode (Cooling): Let’s take
room temperature’s set value 22°C. Whenever
room temperature increases 2°C above this set
value (24°C) compressor starts working. If there
are more than one compressor, both starts
working. If system with two compressors
reaches the set value, (ex. 22°C), the first
compressor stops working. When the room
temperature decreases 1°C below the set value
(22°C), the second compressor also stops
working. If there is a system with single
compressor, when the room temperature
decreases 1°C below the set value, compressor
stops working.
Winter operation mode (Heat Pump): Let’s
take room temperature’s set value 24°C.
Whenever room temperature decreases 2°C
below this set value (22°C) compressor starts
working. If there are more than one
compressor, both starts working. If system with
two compressors reaches the set value, (ex.
24°C), the first compressor stops working.
When the room temperature increases 1°C
above the set value (24°C), the second
compressor also stops working (25°C). If there is
a system with single compressor, when the
room temperature increases 1°C above the set
value (25°C), compressor stops working.
6 minutes of brakes are necessary for each start
and stop of compressors.
Coil Operation System
HybriCool series can be adjusted into coil
system, if necessary.
Heating and cooling coils serve depending on
the operation scenarios of unit. In summer
mode cooling coil (CWC), in winter mode
heating coil (HWC) are activated.
Summer operation mode (Cooling): CWC coil is
activated on cooling mode. After setting up a
set value for room temperature (E.g. 24°C),
whenever room temperature increases above
this set value, CWC coil controls the room
temperature by increasing its capacity, which is
controlled by a proportional valve.
Winter operation mode (Heating): HWC coil is
activated on cooling mode. After setting up a
set value for room temperature (E.g. 22°C),
whenever room temperature decreases below
this set value, HWC coil controls the room
temperature by increasing its capacity, which is
controlled by a proportional valve.
Hot Gas Re-Heat Operation System
Hot gas re-heat system is used in HybriCool
series for controlling the humidity and
temperature in the room more sensitively. With
this application the humidity in the room can be
controlled much more sensitively. The working
principle of this system is almost the same as DX
+ Heat Pump system. With only one difference,
the supply air is cooled much more than
required by evaporator and is transferred to the
hot gas re-heat coil. Here, the supply air is
heated again by hot gas re-heat coil, which is

controlled proportionally, according to required
temperature and humidity values.
Electric Heater Operation System
HybriCool series are only equipped with electric
heater only for heating.
The Electric heater is used on the fresh air side
to protect heat exchanger against freezing,
defrost and as an additional heating capacity in
winter season.
Electric heater works below described
circumstances in winter season:
-If supply air temperature is under the set
temperature value, electric heater starts
working. When set value and supply air
temperature are equal, electric heater
switches into standby mode.
-If room or return air temperature is 5°C
lower than a room set temperature value,
electric heater starts working and
whenever both temperatures are equal,
stops working.
-Electric heater stays active during defrost
mode.
-Electric heater starts operating for 10
minutes when exhaust air temperature
decreases below 3°C on the models
without compressor, then stops working.
After an hour starts working again if the
necessary conditions occur.
Freezing Protection System
Although HybriCool series is optional, we have a
freeze protection, and we recommend that the
temperatures in winter are high or where the
risk of falling is high.
These freezing protections are possible to
separate into two parts: Firstly, the necessary
system protection against freezing on the heat
exchanger and then for the condenser on the
exhaust air side on the models with compressor.
Heat exchanger freezing protection: When the
outdoor temperature falls below -5°C, electric
heater, which is used for preheating, works for
10 minutes, and heats the cold outdoor air,
before entering the heat exchanger. So, this
process prevents the possible freezing in the
exchanger. This process repeats itself once in
each hour.
Condenser freezing protection: Frost and
freezing occur on the surface of condenser,
since the evaporation temperature of the
refrigerant passing through the condenser
decreases in winter. With the help of
temperature sensors on the condenser, the
freezing can be sensed, and the system works
for 15 minutes on defrost mode (ice melting).
During this period, compressors are on standby
mode, air volume is decreased to 25% of
nominal air volume and electric heaters are
activated. By this way the air temperature that
feeds the room works for a while at ambient
temperature levels and above temperatures. At
the end of defrost mode unit returns
automatically to its normal operating values.
Note: During defrost mode, it is unable to
provide normal heating capacity of the unit. At
design stage this situation must be considered.
Free Cooling System
Free cooling system is a standard for each
HybriCool series and provides fresh air into a
room without any power consumption except
EC fans (if there are any compressors, will be
shut down).
This system mostly works in spring and autumn.
When outside temperature is 6°C lower than
room temperature, the Damper will be opened
and fresh air passes through. But when outdoor
air decreases below 10°C, damper will be
closed, and unit returns to its normal operation
conditions.
Constant Air Volume and Variable
Pressure Control System
Air volume remains constant with the help of
pressure differential sensors on fans.
The values of these sensors can be tracked
dynamically and with the calculation below air
volume can be calculated manually:
󰇩
󰇪
This formula above is used for a single fan, if
there are more than one, this formula should be
multiplied by n:
󰇩
󰇪
Here: n is quantity of fans, k is fan constant, ∆P
describes pressure difference.
“k” values of fans are shown in the table below.
