About the DCC DFC and IFC


Frame profiles and cornersDCC DFC and IFC is constructed using a closed framing profile with cast painted aluminium corner pieces. The frame profiles are made of steel with alu-zinc corrosion protection. The result is a strong and robust construc-tion able to resist twisting and lateral movement, making the unit extreme-ly stable and strong.

PanelsThe panels of the DCC DFC and IFC are built using a sandwich construc-tion with double sheets and 60 mm mineral wool for sound and heat insulation. The mineral wool is com-pletely encapsulated, since the panels are closed on all sides.

The panels with alu-zinc surface are not only highly corrosion-resistant, but present an attractive, uniform appear-ance that can last for many years. Steel sheets which are protected with powder coated alu-zinc AZ185 ensure a corrosion protection in class C4 according to EN ISO 12944-2:2000.

Disc-LockAn air handling unit consisting of several sections in size 20-240 can be quickly and efficiently assembled using Disc-Lock, our unique assembly system.

Inspection doorsDCC DFC and IFC has large inspection doors, making service access easy. The doors are mounted using solid hinges with easily removable stain-less steel pins. This means that the doors can be easily removed, if there is no room for normal opening of the doors.

The doors are sealed using rubber profiles and locks with heavy-duty handles. They can only be opened using a key.

Roof unitsDCC DFC and IFC in the sizes 20-240 are available as roof units, designed for outdoor installation. In this version the unit features a roof construction which together with the double seal-ing of the panels provides protection against the effects of the weather. The unit is available with louvers for air intake and exhaust.

Control systemDCC DFC and IFC is always supplied with pre installed and fully integrated Systemair pCO5 control system from Carel. pCO5 is an advanced user-friendly system, that was specially developed for Data Center needs. It is a modern and complicated control system with a large number of fea-tures e.g. alarms, setting of time, operating values and operating sta-tus. The system is prepared for com-munication to a BMS system.


Mode 1. 100% Free CoolingWhen outdoor air (OA) temperature and humidity correspond to needed supply air parameters, outdoor air (OA) is supplied directly to data center room. Warm air from data center is extracted through extract fan or overpressure damper.

Working Modes DCC

Mode 2. MixingDuring low outdoor air (OA) temperature periods, Mixing mode is turned on. Extract air (EA) is partly mixed with outdoor air (OA) in proportion, needed to maintain supply air (SA) parameters.

Mode 3. Cooling SupportIf outdoor air (OA) temperature is higher than needed supply air (SA) tempera-ture, and lower than extract air (EA) temperature, partial support mode starts. During this mode cooling coil maintains supply air (SA) temperature at needed level.

Mode 4. RecirculationIf outdoor air (OA) temperature is higher than extract air (EA) temperature, Recirculation mode starts. Process indoor air will be cooled down by built in cooling coil that is able to maintain 100% of needed cooling capacity. Cooling coil is supported by external chiller or condensing unit.

Humidity Control

If absolute humidity level is lower than demanded, optional steam lance mod-ule will be activated.

If absolute humidity level is higher than demanded, optional dehumidification module will be activated.


Mode 1. Heat ExchangerWarm air from data center room is supplied to plate heat exchanger. Cold out-door air passes through heat exchanger in counter flow air path, without any mixing with indoor air. Indoor air is cooled down by cooling power of outdoor air. In order to maintain needed capacity, outdoor airflow varies depending on air parameters: if temperature goes down airflow is reduced.

Mode 2. HE+AdiabaticWhen outdoor air temperature goes up and its cooling power is not enough to maintain needed capacity, adiabatic evaporative cooling mode starts: outdoor air passes through adiabatic humidifier, where water is evaporated and outdoor air temperature is reduced. Precooled outdoor air is supplied to plate heat exchanger and cools down process indoor air. In order to maintain minimal power consumption outdoor airflow is also reduced according to cooling need in this mode.

Mode 3. Partial SupportDuring very high outdoor air temperature periods partial support mode starts. In this mode there are 2 cooling stages of process indoor air: first it is precooled with help of evaporative cooling and heat exchanger, then it is cooled in built-in cooling coil stage.

Mode 4. Energy Recovery If there is need of Energy Recovery, ERE mode is activated. During this mode outdoor air fan is stopped and all the hot air from White Space (EA) is supplied to ERE coil, that performs as economizer.

FunctionRecuperative plate heat exchanger with high efficiency.

ApplicationThe plate heat exchanger is used where there are special requirements for separation of the two airflows, e.g. in order to avoid transfer of odours to the supply air.

VersionsS – Standard cross flow heat

exchanger Version Q20-240 Average efficiency up to 65%

VariantsThe versions are available in 2 variants:

A – Aluminium heat exchanger Version S, H and C is used in regions where the air does not contain corrosive elements. Many chemicals and solvents do not attack aluminum. This heat exchanger can be used where the air contains these substances. The conditions should be evaluated for each data center.

K – Corrosion resistant heat exchanger. Version S and H. The heat exchanger plates are coated with corrosion resistant synthetic material. Can be used in plants where the air contains elements which attack aluminium.

By-pass mixing damperUnit can be supplied with by-pass mixing damper that can regulate recovery side air temperature for

anti-freeze protection. By-pass damp-er consists of two mixing dampers: from exhaust and intake sides. By mixing of exhaust and intake air at the recovery side optimal low recovery air temperature is maintained.

Service-friendlyThe heat exchanger is equipped with large inspection doors that give access for inspection and service. As the heat exchanger has no rotating part, it requires very little service.

Drip trayA drip tray is fitted beneath the heat exchanger for collection of the water that can condense in the extract air. The drip tray drain outlet must be fit-ted with a water trap that is designed for the actual pressure difference. Refer to the assembly instructions. The counter flow heat exchanger is fitted with a drip tray in both extract and supply air sections.

Function The function is based on the natural process that water evaporates when air passes a wet surface. By uptake of water vapor in the air, the tempera-ture will decrease due to the fact that heat for the evaporation comes from the air. This is an adiabatic cooling, which means that the enthalpy con-tent of the air is unchanged during the process. This ensures that humidi-fication occurs without releasing drops, unless this is effected by entrainment. Entrainment may be avoided by passing the humidification elements with a suitable low speed or by mounting droplet eliminators, which can handle this.

Application

The humidifier is placed in the recov-ery side before heat exchanger to increase indirect free-cooling effect because of adiabatic effect in areas with high outdoor temperature and low humidity.

ConstructionThe humidifier is designed as a com-plete unit that fits the internal dimen-sions of a section of length 970 mm the units 20 to 240. The unit com-prises humidification elements, tray

and frame made of stainless steel AISI 304, circulation pump, balancing valves for irrigation, overflow, valve for adjusting bleed off, float valve for controlling the water supply to the tray and valve for emptying the tray. Droplet eliminator is included if nec-essary and sensor for protection of pump at low water level. The drain is led out of the sec-tion, and can be selected either on the inspection side or the backside. The drain must be connected to a water trap with sufficient locking height.

Humidification elementsHU-CELL humidification elements are stainless steel frames which contains corrugated fiberglass plates arranged in cross-channel configuration. The corrugated cross-channel configura-tion ensures that the air is in contact with a large surface area for evapora-tion, and at the same time provides a low pressure drop. The glass fiber material is impregnated with a stabi-lizing and absorbent additive which makes it possible to absorb water without loss of stability. The element is of inorganic material, and is there-fore not a feed source for bacteria and mould. The material contains sil-

ver ions, which acts as a growth inhibitor. This increases the resistance to the growth of microorganisms and helps to release deposits from the water on the material, so that this remains clean. Silver ions are encap-sulated in a chemical mixture, which ensures that their particles do not dissolve to either water or air. The elements are supplied in the thick-nesses 200 mm. This makes it possi-ble to optimize the pressure drop depending on the desired humidifica-tion/cooling requirement.

Technical dataThe Selection Program calculates all important data such as temperature, relative and absolute humidity after the humidifier, pressure drop and water consumption etc.

FunctionThe function is based on the process

of humidifying air by injection of steam. With this type of humidifying is possible to maintain needed level of humidification, without significant influence on air temperature.

ApplicationThe steam manifold is installed in supply side of the unit after cooling coil to increase humidity level of sup-ply air.

ConstructionSteam humidifier consists of external unit, (carton outer), where water is supplied and steam is produced, steam line (steam and condensate hose) and steam manifold.

Description of workThe steam humidifier utilizes the con-ductivity normally present in tap water for steam production. Electrodes inside an enclosed steam cylinder are immersed directly into

the tap water. They are connected to the alternating current. The conduc-tivity of the water generates an elec-tric current between the electrodes. In this way, the electric power

supplied is converted directly into heat without energy loss.

Technical DataSize and capacity of steam humidifier are determined by need of humidifi-cation, and are calculated in Selection program.

Plug Fan DVE

FunctionPlug fan built into an acoustically insulated air handling unit.

ConstructionSingle inlet plug fan with open outlet into the air handling unit. The fan impeller is fitted directly to the motor. The backward curved impeller has low sound power levels in the lower frequencies. Static efficiency up to 98%.

EC Blue Compact plug fan with an effective composite impeller, and EC external rotor motor with integrated variable speed control. The EC motor is in effi-ciency class IE4.

Plug fanEC Blue is a compact plug fan with an impeller made of composite material, where all details are optimized in order to achieve a high efficiency. The impeller is fitted directly to an EC external rotor motor with integrated variable speed control. An EC motor is characterized by a high efficiency and excellent control features. For opti-mizing the efficiency in the operating points, the fan can be selected in several variations in each unit size. Several fans can be positioned in par-allel operation at larger units. The fans are mounted on the end wall of the fan section.

Positioning in the air handling unit A plug fan supplies air at the fan sec-tion outlet with a low and even air speed. Therefore, it is an advantage to position air handling components on the outlet side of the fan.
