Our contribution to energy saving and CO2 emissions reduction

2

Nowadays, the need toadopt effective actions topromote energy saving, as well as a drastic reductionin CO2 emissions into the atmosphere, is universallyrecognised.In Europe, there are in factseveral million of sub-fractional horsepowerelectric motors used both in domestic appliances, or in air-conditioning and refrigerators. For the latter,especially for the ventilationof refrigerated display cases,sub-fractional HP motors with extremely low efficiencyhave always been used. For example, approximately8 Watts of shaft output powerare needed to operate a 230 mm diameter fan blade,which can be obtained fromthe following types of motor:

Shaded poles: input power ~ 36 Wattefficiency ~ 18%

Electronically commutated: input power ~ 12 Wattefficiency ~ 65%

The importance of choosinga high-efficiency motor is evident from considering a single supermarket with approximately 200 m of refrigerated display unitsinstalled, for an estimatedtotal of 200 fan motors.

Considering an averageenergy cost of 0.11 Euro per kWh and CO2emissions of 0.6 kg per kWhconsumed, we can calculate that if the same supermarketused “electronic control”motors instead of the equivalent “shaded pole”models, 68,500 kWh could be saved in one year,equivalent to approximately7,500 Euro and a reductionin CO2 emissions of 41 tonnes.

The sensible energy savingwidely compensates the greater cost of high-efficiency motors, withpayback in just few months: in fact, in the lifetime overallcost of a shaded-polemotor, energy consumptionrepresents almost 97-98%,while its purchase costsonly 2-3%.

Moreover, reduced CO2emissions is a topic of great interest in relationto the maximum quotasassigned to each countryand the related “carbontrading” that regulates the “emission credits” marketbetween virtuous users andless-virtuous ones.

Within this context, thanksto over 800,000 high-efficiency ECM motorsalready supplied to themarket, ELCO has contributed to a reductionin environmental emissionsof an estimated 116,000 tonnes of CO2per year.

To confirm the high-efficiency and consequentlythe cost advantage of ECM motors, a two-monthstest was carried out byindependent consultants at a large foodstore supermarket located inTortona (Northen Italy), by monitoring a specificarea of refrigerated display cases coveringapproximately 200 fanmotors. Energy consumption wasmonitored by initiallyrecording the usage of the traditional shaded polemotors and then replacingthem with ELCO’s ECMmodels.Tests results showed a saving of 142,423 kWhagainst a Total EnergyConsumption of 614,466kWh; the equivalent of approximately 85 tonnes of CO2.

Similar tests were carried outin some European supermarkets, where todayonly ELCO motors are used.The results have not only confirmed large savings, but also more uniform airflow thanks to the greatertorque of ECM motors.

The advantages with towards the “shaded pole”solution are:

• High efficiency 63÷68%

• Maximum moisture protection with the new IP65-IP66 versions

• Reduced depth comparedto the standard N serie Shaded Pole motors

• Drop in replacement with the standard N series and possibility to use all standard accessories

General specifications

ELCO SpA has developedand patented a new range of high-efficiency sub-fractional horse powerelectronically commutatedmotors - the ECM series.This new generation of motors is specificallydesigned to satisfy the growing market demands of“energy saving”, granting first-rate results in terms of efficiency and life expectancy.

The motor, totally enclosed in a thermoplastic housing,contributes to limiting external heat emission, whichresults in a particularly coolmotor body during operationand hence generate a furtherenergy savings.Thanks to a special, permanent lubrication systemand based on laboratorytests, the life expectancy isapproximately 30,000 hoursfor the Standard version and 60,000 hours for the Long Life version.

The ECM series is currentlyavailable in two single-speedversions, to be selectedaccording to power requirements.

Interchangeability:

The ECM motor was alsodesigned to comply with the same principle of standardization that ELCOdeveloped for the N-seriesmotors.

In fact, ELCO’s “energy saving” motors are,drop-in replacements of the traditional shaded poleones, and use all the sameaccessories, such as brackets, fans, rings andguards, with no extra work- or hidden costs, to the full benefit of rapidity andconvenience.

Applications The ECM series motors may be universally applied, but are particularly suited to the refrigeration and ventilation industry,especially for refrigerateddisplay cases, freezers,drink dispensers and smallcondensers; they can becoupled with various typesof fan blades, particularlyaxial fans with diameters up to 300 mm.

Construction Product description:

The IP65 version comes with an O-ring to seal therear plastic end-shield to themotor housing and mouldedcable grommet, sleeve or ball-bearings and a newfan profile integrated with the internal watherprooflabyrinth.While in the IP66 version,the motor has a double-sided rubber sealedball-bearings and cable exitfitted with an IP68 strainrelief.

The electronic control unit isprovided with various safetyfeatures:

• Overload control function, which switches the motor to standby mode if an external mechanical actioncauses the speed to drop below a preset level.

• Locked rotor control function, which switches the motor to standby modeafter twenty restart attempts, in case of fan blocked by icing or other reasons.

• Auto-reset function, which allows the microprocessor to reset and restart the control functions, in cases of electrical interference or power supply fluctuations.

• Self-diagnostics function during switch-on and switch-off. In cases of ON/OFFalternative use, each cycles should be at least 20 seconds apart.

• Power shut-down function in cases of microprocessorfailure.
