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
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.
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...”.
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 190-980
– periodically at least once every 12 months,
i.e. no more than 12 months between inspections, size 190-980
– within one month of any work being performed (e.g. sealing a leak, repla-
cing a
component), size 190-980
• 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 190-
980.
If a unit has been assembled on site, the rules for recording, installing and perio-
dic leakage inspection are applicable to size 100-150 as well.

2 Technical description
2.1 Cooling/heating pump ThermoCooler HP
ThermoCooler HP is a series of integrated, speed controlled reversible heat
pumps with stepless cooling and heating power.
Cooling circuit function
The reversible heat pump has four basic components: evaporator, condenser,
expansion valve and compressor.
A 4-way valve is used to shift between cooling and heating.
For cooling, the 4-way valve is in cooling mode. For heating, the 4-way valve
is in heating mode. This means that the coil, which was a condenser in cooling
mode, becomes an evaporator in heating mode. Conversely, the evaporator
becomes a condenser.

Cooling mode
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 in the extract air.
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.
Heating mode
The heating pump function takes the heat content of the extract air and reuses
it, supplying the same heat to the air handling unit’s supply air.
The extract air is the heat pump’s energy source. When the extract air meets the
extract air coil, it is cooled since the coil functions as an evaporator. From the
evaporator, the refrigerant moves to the compressor, where it is compressed.
The refrigerant then moves to the supply air coil, where the energy from the
extract air and the compressor is released. The energy remaining in the extract
air downstream of the heat pump is then recovered in the rotor.
These two recovery systems give a very high degree of efficiency.
Since the rotor requires less energy to run than the compressor system, this will
be in the first instance. The compressor will only start when the rotor’s energy
recovery is insufficient to heat the supply air.
Compressor
The reversible heat pump is equipped with a speed-controlled PM scroll
compressor.
Depending on its size, the reversible heat pump may be equipped with another
fixed compressor that is step-linked to the speed-controlled compressor.
In the event of an increased power requirement, the frequency inverter will
increase the speed of the compressor.
If the reversible heat pump is equipped with two compressors, the fixed com-
pressor 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 cooling power.
The function is reversed where less cooling is needed.

DSTCH.191101.01.EN
Continuous product development may give rise to specification changes without notice.
Compressor protection
In the event of an alarm initiated by the control equipment or the safety circuit,
the compressor stops and an alarm indication is given. The alarm can be read
on the Climatix display or the Carel unit on the unit’s circuit board.
In the event of an alarm, correct the fault and then reset the alarm. If alarm trips
repeatedly, an authorised refrigeration service company must be called in.
The cooling/heating pump will primarily trip alarms for the following errors:
• High pressure in the system, manual reset on pressure control HP1
• Low pressure in the system
• Alarm from frequency inverter
• Incorrect phase sequence (size 600-980).
Function
The reversible heat pump is interlocked across the air handling unit. If any of the
fans stop, the cooling/heating pump will also stop. The reversible heat pump is
not permitted to start unless the minimum air flow has been achieved. The same
applies if a heater is fitted.
The interlock and demand signal is sent via Modbus.
Circuit board
The circuit board for the unit contains:
• Main switch
• Fuses
• Control unit
• Any control unit for expansion valve next to fixed 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 unit must be carried out by competent personnel accor-
ding to the commissioning procedure, see
ThermoCooler HP, Commissioning record, which is available to download from
ivprodukt.docfactory.com.
The validity of the product warranty is conditional on the system having been
commissioned correctly. Working on the unit during the warranty period without
the approval of IV Produkt shall render the warranty void.
The unit was designed and manufactured based on given operation cases
that must comply with the unit’s use for optimal function and a good operating
economy.
External circumstances should not be changed without checking that such
changes are within the unit’s intended area of operation.
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.
NB!
For units in size 600-980 (2-circuit), the compressor for the second
circuit is dependent on the correct phase sequence. Compressor 2
starts briefly 30 seconds after powering up the unit in order to check
the phase sequence. Check whether the alarm is displayed.
If necessary, switch two of the incoming phases.
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.

5 Maintenance instructions
5.1 Service schedule
For a service schedule, see Operation and Maintenance for Envistar Flex, under
order-specific documentation at docs.ivprodukt.com.
5.2 Periodic inspection
The operation parameters for the reversible heat pump must not be changed
unless a check is first made to ascertain that the changes will be within the
unit’s operating range.
Leakage inspection and registration
For information on the operator’s responsibility with regards to leakage inspec-
tion and registration, see "1.7 Handling of refrigerant" page 5.
Visual check
Check:
1. The fins on the condenser/evaporator to detect mechanical deformations
2. The drip tray and drain with water trap (clean if necessary)
3. That the water trap (without non-return valve) is filled with water.
Cleaning
If the fins are fouled, they should be vacuumed from the inlet side. Alternatively,
you can blow them clean with compressed air from the outlet side. If they are
severely fouled, you can clean them with warm water mixed with dishwashing
detergent that will not corrode aluminium.
For more information, refer to Cooling coil, cleaning under Documentation at
ivprodukt.docfactory.com.
Check function
Check that the reversible heat pump in the air handing unit is operating as it
should by temporarily lowering/increasing the temperature setting (setpoint).
