Free Cooling mode

Heating mode: In winter, comfort temperature is maintained thanks to the thermodynamic system and auxiliary heaters (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.

Description

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.

■ Rigid, compact and lightweight packaged unit, perfectly weather-resistant, with a 20-year anti corrosion guarantee on casing.

■ Watertight floor with drainage outlets around the unit, connected to rubber siphons.

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

■ Access through large “easy to remove” panels. Panels are closed with square locks. Doors tightness is ensured by a flexible gasket under compression, providing an ideal elasticity day after day (French standard NF EN 1886).

■ High performance supply air plug fan to avoid losses due to pulley-belt transmissions, thus improving unit energy efficiency.

■ Inner acoustic and thermal insulation on panels using 25 mm M0 glass wool, in accordance with French Public Access Buildings regulations (Article CH36).

■ Floor sound and thermal insulation using 20 mm acoustic foam.

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

Optimised defrosting:

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 flows downwards.� The coil is dried.� The other refrigeration circuit continues to operate normally.

Aluminium frame and casing:

Description

■ Filter assembly with easy-to-remove ecodesign filters - 98 mm pleated media, efficiency 95% ASHRAE gravimetric (G4) for longer lifetime and lower pressure drops, pressure switch for fouling control.

■ Supply air plug fan. This technology avoids losses due to pulley-belt transmissions.

■ Electronically commutated motors allow: � 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).

■ Refrigeration circuits compliant with European directive on pressure equipment (PED 97/23/EC).

■ R410A refrigerant. ■ Direct expansion internal exchanger,

made with copper pipes and aluminium fins and frame, coupled with a thermostatic expansion valve in heat pump mode.

■ Direct expansion external exchanger, made with copper pipes and aluminium fins and frame, coupled with a thermostatic expansion valve in heat pump mode.

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

■ 2 expansion valves per circuit and per refrigeration cycle to optimise the efficiency 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 flow rate increases by up to 15% compared to standard fans, while keeping the same power input. The new blades profile results in lower compressors consumption thanks to lower HP and higher LP in the different operation modes.

■ Anti-acid filter drier. ■ HP and LP switches. ■ Cycle reversal valve.

■ 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 boxes. � 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 with numbered ferrules at both extremities. � Ik3 breaking capacity of basis 10 kA. � All components protected by circuit breakers. � LV distribution rated voltage compliant with French standards, i.e. rated voltage of 230/400V. French standards also set minimum and maximum acceptable values at the user supply point (average value for 10lm) 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.

■ 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 in order to add functions requested for some applications and to 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 shock 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 via dry contact for transfer on customer system. � 2 setpoints (cooling and heating) according to the European directive 2002/91/EC. � Security management (freezestat, smoke detector, HP switch, etc.) and faults management. � Optimisation and equalisation of compressors operating time.

� Flash-type analogue and economical management of alternate defrostings for each refrigeration circuit using frost detection and end of defrosting through analogue probes, stop of the concerned exchanger’s ventilation, coil drying and starting of a new heating cycle in heat pump mode. External coils angled position and downward supply air flow help blowing water away from the coil, ensuring efficient defrosting. Concerning multi-circuits units, comfort and energy savings are ensured by banning simultaneous defrostings. � 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. � Frost protection. � 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 time 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.

Dehumidifi cation option with heat recoverythrough in-line condenser

The dehumidifi cation option is only available on EFFI+ R series. It adds a new feature to the heat pump that enables room humidity regulation. This feature is particularly suited for large and medium-sized stores, where the installation of numerous closed refrigerated showcases requires a treatment of latent contributions through air handling.

Various confi gurations are available (number of in-line condensers, auxiliaries, etc.) to adapt to each specifi c project.

Return air fl ows through the evaporator(s), causing humidity contained in the air to condense. Heat is recovered and transferred thanks to the in-line condenser. There is no wasted energy since the heat from the evaporator and the electrical power from the compressor are transferred to the air stream. Auxiliary heating may be installed (hot water coil or electric heater) depending on the heating needs. The heat recovered may also be rejected on the external condenser (in summer).

Depending on outdoor and indoor conditions, control enables dehumidifi cation through fresh air introduction, which avoids using the thermodynamic system.

EXAMPLE OF SELECTION

EFFI+ R325, all 3 circuits are equipped with dehumidifi cation option for maximum dehumidifi cation capacity (58 L/h in Heating mode with 20°C/50% RH return air conditions). 2 circuits are equipped with an in-line condenser to maximise energy recovery (92.6 kW in Heating mode with 20°C/50% RH return air conditions)Circuit 1: Level 2 (energy recovery)Circuit 2: Level 3 (energy recovery and supply air temperature control)Circuit 3: Level 12 hygrometry probes are supplied (internal and external). The installer is in charge of connecting the internal probe and shall supply and install the connecting cable for master/slave operation with other units.

Level 2: Dehumidifi cation with energy recovery through in-line condenser, on/off refrigeration 3-way valve and year-round kit. The heat recovered is transferred either to the air stream or to the external condenser depending on the season or on the supply air temperature setpoint. An additional auxiliary heater may be installed for winter operation, depending on project characteristics.

Level 3:Dehumidifi cation with energy recovery through in-line condenser, analogue refrigeration 3-way valve and year-round kit. Supply air temperature control: When supply air temperature is reached, excess heat is evacuated through the external condenser. An additional auxiliary heater may be installed for winter operation, depending on project characteristics.
