1.7 Handling of refrigerant
The following information summarises the requirements and guidelines for hand-
ling the refrigerant used in cooling units. For further information, see the F-gas
Regulations (517/2014). The purpose of the regulations is to contribute to achie-
ving EU goals for reduced climate impact in accordance with the Kyoto Protocol.
Operator responsibilities
By operator, we refer to the European Parliament’s definition: “...the natural or
legal person exercising actual power over the technical functioning of the equip-
ment and systems...”.
Generally speaking, the unit operator must:
• Minimise and prevent leakage
• Take corrective action to repair any leakage that arises
• Ensure that the service and repair of the refrigerant circuit is carried out by a
certified refrigeration technician
• Ensure that refrigerant is handled in an environmentally secure manner and
in accordance with national regulations.
The levels for the various actions to be taken for a system are calculated using
carbon dioxide equivalents, CO₂ e(ton). This figure is calculated by multiplying
the refrigerant’s GWP value (Global Warming Potential) by the charge in kilos.
GWP for R410a is 2088. A charge of 5.0 kg R410a therefore corresponds to
(5.0×2088)/1000 = 10.44 CO₂ e(tons).
The unit is marked with refrigerant quantity and carbon dioxide equivalent.
Leakage inspection and registration
• Leakage inspection must be carried out by a certified refrigeration techni-
cian:
– when installing/commissioning the unit, size 300-980
– periodically at least once every 12 months,
i.e. no more than 12 months between inspections, size 300-980
– within one month of any work being performed (e.g. sealing a leak, repla-
cing a component), size 300-980
• The operator must record events, such as the volume and type of refrigerant
topped up, recovered refrigerant, results of inspections and work done,
person and company who carried out service and maintenance, size 300-
980.
If a unit has been assembled on site or supplied in sections, the rules for recor-
ding, installing and periodic leakage inspection are applicable to size 150-240 as
well.

2 Technical description
2.1 Cooling unit, EcoCooler
EcoCooler is a range of integrated speed controlled cooling units with stepless
cooling power.
Two different versions of EcoCooler are available:
• without cooling recovery (without rotary heat exchanger), code ECO
• with cooling recovery (with rotary heat exchanger), code ECX. Cooling
recovery means that the thermal wheel starts up when the extract air/room
temperature drops below the outdoor temperature and cooling is required.

Cooling circuit function
A cooling system has four basic components: evaporator, condenser, expansion
valve and compressor.
The compressor carries out the work required to run the cooling process.
The evaporator is located in the supply air for the unit. The heat from the outdoor
air is taken up in this coil, thereby cooling the supply air.
The energy supplied to the cooling system from the evaporator and the com-
pressor leaves the unit via the condenser. The condenser is located in the ex-
tract air (ECO) or the exhaust air (ECX). This means that the exhaust air becomes
hot when the cooling unit is running.
It is important to ensure that the air volumes are above the specified minimum
flow on both the outdoor air and extract air side. The process cannot work if
these air volumes are not available.

Compressor
EcoCooler is equipped with a speed-controlled PM scroll compressor. Depen-
ding on its size, the unit may be equipped with another fixed compressor.
When cooling is required, the frequency inverter increases the speed of the
compressor.
If the EcoCooler is equipped with two compressors, the fixed compressor will
engage in when the speed-controlled compressor has reached its maximum
speed. The speed-controlled compressor returns to its minimum speed and can
then adjust back up to maximum speed. This achieves infinitely adjustable coo-
ling power.
The function is reversed where less cooling is needed.
Compressor protection
In the event of an alarm initiated by the control equipment or the high pressure
switch, the compressor stops and an alarm indication is given. If the unit is
equipped with integrated control equipment, the alarm can be read on the Cli-
matix display.
In the event of an alarm, correct the fault and then reset the alarm. If the high
pressure alarm trips repeatedly, an authorised refrigeration service company
must be called in.
The high pressure switch is tripped when the system is at high pressure and has
a manual reset button. To avoid accidental stoppages at high pressure, the unit
will lower the power using the high pressure sensor.
Cooling function
For internal control (MX), the cooling unit is interlocked across the air handling
unit. If any of the fans stop, the cooling unit will also stop. The interlock and de-
mand signal is sent via Modbus.
For external control (US, UC and MK), the interlock signal must be sent via a
potential-free relay. The demand signal must be sent via 0–10 V.
Circuit board
The circuit board for the cooling unit contains the following:
• Main switch
• Fuse
• Control unit with integrated control for expansion valve next to speed control-
led compressor
• Control unit for expansion valve next to fixed speed compressor
The circuit board is installed inside the unit and is internally prewired and tested
at the factory.

4 Operation
4.1 Commissioning
Commissioning of the cooling unit must be carried out by competent personnel
according to the commissioning procedure, see
EcoCooler, Commissioning record, which is available to download from
ivprodukt.docfactory.com.
The commissioning procedure applies to units that are supplied with control
equipment (code MX).
The validity of the product warranty is conditional on the system having been
commissioned correctly. Working on the cooling unit during the warranty period
without the approval of IV Produkt shall render the warranty void.
NB!
It is important that the oil is warm inside the speed controlled compres-
sor crankcase before starting the cooling unit. The crankcase heating
must be switched on long enough before the unit begins operating so
that the oil maintains a temperature of at least 30 ºC. The maximum
warm-up time is approximately 2–3 hours. The temperature can be
measured externally at the bottom of the compressor.
Prior to commissioning, the contractor must:
NB!
Wiring of connections and other electrical work may only be carried out
by a qualified electrician or by service personnel recommended by IV
Produkt.
1. Connect the unit to the power supply via a lockable safety switch.
2. Connect all ducts.
WARNING!
Rotating fan impeller. The unit must not be energised until all
ducts have been connected.
Follow the troubleshooting instructions in the troubleshooting chart before
contacting a service representative for servicing a unit under warranty. This will
prevent any unnecessary service calls.
