Free Cooling mode

Heating mode: In winter, comfort temperature is maintained thanks to the thermodynamic system and the auxiliaries (optional).

Cooling mode: In summer, comfort temperature is maintained thanks to the thermodynamic system.

Free Cooling mode: In mid-season, comfort temperature is maintained using in priority the difference between outside air and inside air to cool the building.

Free Cooling allows considerable savings by delaying the use of thermodynamics.

The ETT packaged unit comprises 3 different sections:

1 The external section allows thermal exchanges with the environment.

2 The separate technical section houses the refrigeration components, the electrical board and the control components.

3 The internal section ensures air change and air treatment.

Aluminium frame and casing:■ Rigid, compact and lightweight

packaged unit, perfectly weather-resistant, with a 20-year anti corrosion guarantee on casing.

■ Watertight fl oor with drainage outlets towards the border of the unit and connected to rubber siphons.

■ Aluminium vertical panels and roof, mounted on aluminium frame.

■ Access through large removable panels. Panels are closed with square locks. Doors tightness is ensured by fl exible gasket under compression, providing an ideal elasticity day after day (French standard NF EN 1886).

■ High performance free wheeling ventilation on supply air section to avoid losses due to pulley-belt transmissions, thus improving unit energy effi ciency.

■ Inner acoustic and thermal insulation on panels using 50 mm thickness M0 glass wool, in accordance with Public Access Buildings regulations (Article CH36).

■ Floor acoustic and thermal insulation using 100 mm M0 rock wool with double skin.

■ 2-damper mixing box including a motorised fresh air damper with bird proof grid and a motorised return air damper to ensure the desired proportions and optimise "Free Cooling" economiser phases. Dampers have extruded aluminium blades with low pressure drop thanks to their plane wing profi le and a fl exible gasket which ensures excellent air tightness. The damper frame is made of tightness class 3 aluminium.

Description

Defrost optimisation:

Defrosting principle:� The condensation of humidity produces frost on the coil.� The concerned refrigeration system and propeller fan stop

operating (simultaneous defrosting cycles are banned).� The refrigeration system 4-way valve reverses: during defrosting, the

coil operates as a condenser.� Supply air downwards� Coil drying� The other refrigeration circuit continues to operate normally.


6

Description

Air assembly:■ Filter assembly with easy-to-remove

eco-concept fi lters - 98 mm pleated media, effi ciency G4 95 % ASHRAE gravimetric test for longer lifetime and lower pressure drops, pressure switch for fouling control.

■ Free wheeling supply air fan. This technology avoids losses due to pulley-belt transmissions.

■ Each electronically commutated motor allows:

� reduced kickback during start-up when textile ducts are used (soft start mode);

� maximum rotation speed regulation according to pressure drops on site;

� reduced speed operation in free-cooling mode to save energy (VDP operation).

Energy and thermodynamic assembly:■ Refrigeration circuits compliant with

European Directive on pressure equipment (PED 97/23/EC).

■ R410A refrigerant.■ Direct expansion internal exchanger

with copper pipes and aluminium fi ns and frame, coupled with an expansion valve in heat pump mode. These nested exchangers improve SCOP and SEER in partial load. In addition, the air fl ow rate can be adjusted according to the required capacity, reducing signifi cantly ventilation energy consumption (VDP operation).

■ Direct expansion external exchanger with copper pipes and aluminium fi ns and frame, coupled with a thermostatic expansion valve in heat pump mode. External exchangers angled position and the separation by refrigerant circuit and by compressor ensure quick and effi cient defrosting.

■ Optimised defrosting thanks to the new design of the external section and the integration of a Ø 800 mm propeller fan with supply air downwards (optimised for ecodesign).

■ Tandem hybrid circuits, operation in part load reduces signifi cantly the number of defrost cycles and their duration.

2 expansion valves per circuit and per refrigeration cycle to optimise the effi ciency of each evaporator cycle and reduce energy consumption.

■ Independent refrigeration circuit: each refrigeration circuit has a propeller fan to ventilate the exchanger. The propeller fan consists of a ferrule, a high energy performance 5-blade aluminium propeller coupled with an IP54 motor with reinforced sealing, and a zinc-plated steel fan guard, with cataphoresis protection. The fan assembly is perfectly weather resistant. Thanks to this new designed fan, exchangers air fl ow rate increases by up to 15 % compared to standard fans, while keeping the same power input. New blades profi le results in lower compressors consumption thanks to lower HP and higher LP in the different operation modes.

■ Anti-acid fi lter drier.■ HP and LP switches.

■ Cycle reversal valve.



7

Control description

Electrical assembly:■ Electrical board compliant with

European standards EN 15-100 and EN 60204-01, including:

� ETT controller with display.� Power switch with lockable

external handle for full load cut-off. Connection using standard universal cable. Optional copper/aluminium connection terminal blocks.

� 400-230-24 volts transformer for regulation and control circuits.

� Faults synthesis with pending dry contact on terminal.

� Numbered terminal blocks with disconnecting terminals for remote controls and transfers.

� Terminal block for compressors load shedding.

� Internal wiring numbered at both extremities using numbered ferrules.

� Ik3 breaking capacity of basis 10 kA.� All components protected by circuit

breakers.� Rated LV distribution voltage

compliant with French standards indicating 230/400V for the rated voltage French standards also set minimum and maximum acceptable values at the user supply point (10 mn average values) within a -10%/+10% range from rated values and maximum acceptable value of the voltage drop gradient to 2%. The voltage drop gradient represents the additional voltage drop created on a network point if 1 KW single-phase is added on this point.

Control assembly:■ CTN type temperature probes. Their

accuracy and liability have been tested and validated both at the factory and on site.

■ One or more BEST-type controllers (Building Energy Saving Technology) especially developed by ETT for this range of units. Programs are updated annually to add functions requested for some applications and optimise units electricity consumption.

The microprocessor, memory and controllers size are adapted to the chosen applications and options by integrating a program set-up in the factory out of 160 possible confi gurations. The controller is in a plastic box which guarantees a high mechanical protection and reduces electrostatic shocks threats.

Among other functions, the controller includes:

� On/Off with remote contact or vacancy contact.

� On/Off according to programmed schedule (2 time slots per day).

� Fault synthesis with dry contact for transfer to customer system.

� 2 setpoints (cooling and heating) according to the European directive 2002/91/EC.

� Security management (fi re thermostat, smoke detector, HP switch, etc.) and faults management.

� Optimisation and equalisation of compressors operating time.

� Economical analogue management of alternate fl ash-type defrost cycles for each refrigerant circuit using frost detection and end of defrosting through analogue probes, stop of the concerned exchanger ventilation, coil drying and starting of a new heating cycle in heat pump mode. External coils angled position and downward supply air fl ow help blowing water away from the coil, ensuring effi cient defrosting. In the case of multi-circuits units, simultaneous defrost cycles are banned to preserve comfort and energy savings.

� Economiser management (Free Cooling) through inside temperature analysis and comparison between return air and outside air temperatures.

� Compressors stages management giving priority to the highest COP and EER in part load.

� Out-of-frost restart.� Auxiliaries management (possibility

of banning according to outside temperature).

� Night energy consumption management with compressors' use limitation (night cooling).

� Written faults history (no code needed) with hour and outside temperature display.

� Operating hours counting (unit, compressors and auxiliaries).

� Air quality control with CO2 probe to optimise fresh air quantities to introduce, therefore limiting energy consumption.

P 84-206-1 (Grooved sheet metal roofi ng with waterproofi ng coating) and fi re-safety regulations for PAB.

■ The packaged aluminium roof curb is considerably lighter than galvanised steel constructions.

■ Adjustable angles compensate the roof slope. Other slope percentages are available on request (optional). Please confi rm the roof slope percentage and direction.

■ 200 mm ventilated air space in accordance with French fi re-safety regulations for Public Access Buildings (PAB). The unit is mounted on 4 (or 6) bolted feet and water tightness is ensured by a foam gasket on supply air and return air duct frames.

■ The air space also provides sound insulation since it considerably reduces radiated noise from below the unit.

■ 200 mm length double skin insulated supply and return air duct connections, with external aluminium mechanical protection.

■ Cable ducts below the unit for power cable and hot water coils piping.

■ The roof curb is insulated from below with 25 mm glass wool with a protection veil. The insulation is secured with aluminium clips welded on the sheet metal for a better fastening than gluing methods. Insulation limits thermal losses and avoids under-surface condensation.

■ Cap fl ashing allows continuous insulation and waterproofi ng membrane (up to 100 mm thick) on roof curb external side as stipulated by 2002/91/EC Directive.

■ Roof curbs are intended for steel decks up to 145 mm high and insulation up to 200 mm high (i.e. max. H=345 mm).

■ Lifting lugs facilitate cranage.
