1. INTRODUCTION AND MOUNTING
1.1 optiMist description
optiMist is an evaporative cooler and humidifier that atomises water in
fine droplets which then spontaneously evaporate, removing heat from
the humidified and cooled air.
optiMist uses a vane pump to pressurise the water, subsequently
atomising it through special nozzles.
The sophisticated control system combines the action of an inverter,
which regulates the speed and consequently the flow-rate of the pump,
with two solenoid valves that activate only the necessary nozzles,
allowing the system to always work at the ideal pressure to atomise the
water, across a wide range of flow-rates.
The effect of cooling the air is due to the spontaneous evaporation of
the droplets of water: the change in state from liquid to vapour occurs by
subtracting energy from the air that, as a consequence, is cooled.
Each kilogram of water evaporated absorbs 0.69 kW of heat from the air.
optiMist is a complete evaporative cooling and humidification system
that can be used to treat the air in an AHU (air handling units) and to
both humidify and to indirectly cool the renewal air, in order to increase
the energy efficiency of the AHU.
1.2 Components of the system
optiMist is comprised of
• a pumping station that pressurizes the water (4-15 bar). It also contains
the electronic controller that completely manages the pumping
station, controlling the temperature/humidity in each section. Since it
is equipped with an inverter and pressure sensor, it manages to control
the flow of water produced at any moment, thus ensuring maximum
precision and minimum energy and water consumption.
• distribution and atomisation system of pipes for transporting the
pressurised water, which contain the atomisation nozzles and drain
valves;
• droplet separator;
• temperature and/or humidity probes or control through external
signal;
• water treatment system: typically this is a reverse osmosis demineraliser
that supplies water with a low mineral salt content to the optiMist.
1.3 Configuration of the optiMist system
The optiMist system can be configured to:
1. Controlthe air humidity,installing a pumping station and adistribution
system (with two-step modulation) in the AHU humidification
section.
Fig. 1.a
2. Control indirect evaporative cooling (IEC) by installing a pumping
station and a distribution system (with two-step modulation) in the
upstream section of the AHU heat recovery unit.
Fig. 1.b
3. Control both humidification and evaporative cooling with a pumping
system that will serve the two distribution systems, each with one-
step modulation.
Fig. 1.c
The configuration for indirect evaporative cooling applications is of
particular importance. Besides humidification of the air in the winter,
optiMist can be used in the summer to cool the discharged air in the
summer before it enters a heat recovery unit.
This configuration is explained in the detail in the chapters below.
optiMist humidifiers are available for:
• flow-rates: 50 l/h (EC005...), 100 l/h (EC010...) 200 l/h (EC020..), 400 l/h
(EC040..), 800 l/h (EC080..) and 1000 l/h (EC100..);
• power supply voltage: D = 230 V 50 Hz; U= 230 V 60 Hz;

2. In the case of two racks or one two-step rack, mount the pipes parallel,
avoiding any contact.
3. In laying the pipes, avoid conditions that could cause the water to
stagnate with the system is halted.
Connect an expansion tank (not supplied by CAREL SpA) with a capacity
of at least 5 litres, upstream from the cabinet in order to prevent water
hammering which can damage the system.
The connection to the cabinet must be performed using flexible piping..

2.2 Type of supply water
optiMist can work with:
• demineralised water
• soft water
• tap water
Following the evaporation process, the minerals dissolved in the
supply water will be partially transported by the air flow
as very fine powder and part of them will be deposited on the surfaces of
the separator and the fins of the heat exchanger.
The type and amount of minerals contained in the supply water
determine the frequency of regular maintenance operations needed to
remove these deposits from inside the AHU.
The main components of the system supplied by Carel which are affected
by any incrustations and which require regular periodic inspection and
maintenance are the nozzles and droplet separator.
In order to maintain system hygiene and to reduce system management
costs, Carel recommends supplying optiMist with water that has been
demineralised by reverse osmosis, as provided for in the principal norms
such as UNI 8884.
In particular, Norm UNI 8884 “Characteristics and treatment of water for
cooling and humidification circuits”suggests that evaporative humidifiers
be supplied with fresh water (as indicated in directive 98/83/EC) having
the following characteristics:
• electrical conductivity <100 S/cm;
• total hardness <5 °fH (50 ppm CaCO3);
• 6.5<pH< 8.5;
• chloride content <20 mg/l;
• silica content <5 mg/l;
Note 1: If demineralised water is not available, softened water may be
used. In this case, in order to limit the aggressiveness of softened water, a
minimum hardness no less than 3°f should be ensured.
Note 2: Carel recommends using mains water only if it has a hardness of
less than 16°f or a conductivity of less than 400S/cm.
The use of mains water leads to ordinary maintenance operations (nozzle
and droplet separator cleaning) whose frequency depends on the
chemical composition of the water.

3.7 Modulating control signal
The control signal input connections depend on the activated control
algorithm.
Cables up to 30 m: two-wire cables cross-section 0.5 mm2(AWG20)
To control the section for direct humidification (DEC: Direct Evaporative
Cooling), the signal can come from:
• modulating control with external controller
• modulating control with limit probe (temperature or humidity)
• modulating control with humidity probe
• modulating control with humidity probe and limit probe
(temperature or humidity
To control the section for indirect humidification (IEC: Indirect Evaporative
Cooling), on the other hand, the signal can come from:
• modulating control with external signal
• modulating control with limit signal (temperature or humidity
probe or air flow-rate/flow limit signal)
• modulating control with temperature probe
• modulating control with temperature probe with limit signal
(temperature or humidity probe or air flow-rate/flow limit
signal)
Tab. 3.c
To set the type of operation, control and signal: “installer menu > control
type (see chap. 9.11 Installer Menu).”
Note: The use of shielded cables is recommended. The cables must
not be lodged near power cables at 230 V/208 V or near remote control
switch wiring: this way, the risk of measurement error risks from
electromagnetic interference can be avoided.

Backup function
The backup function allows the activation of a supporting cabinet in case
of unexpected switch-off of the main cabinet.
Two types of backup management are available:
• HBT: control on the heartbeat of the main control
• BMS: control by supervisor
The HBT control allows the activation of the backup cabinet keeping
controlled the heartbeat (digital output HBT) of the main Optimist. Wiring
the digital contact HBT with the BKUP input of the backup cabin, the
backup function check if the heartbeat is active (BKUP contact closed). If
the signal dies (BKUP contact opened), the backup cabin starts working.
The BMS control check the status of the DIG 75 variable.
If the variable is 1, the backup cabin is off; if it switches to 0, the backup
cabin starts working.
Note: The enabling of the backup function must be set only in the
Optimist for backup, inside “Zone Menu Special Function 2/3” in
Installer menu

Rotation function
The rotation function allows the periodical activation of the two cabins.
In the main cabin:
• enable Rotation function,without enabling the backup;
• set the Rotation time value.
In the backup cabin the HBT control must be set.
To permit the rotation to work, the wiring of the HBT control must be
done from the main cabin to the backup one and vice versa.
