EC Fans – Growing in Popularity

Energy conservation is of ever increasing importance in today’s world. About 25% of the primary energy consumption in the residential and commercial sectors is used by electric motor-driven systems and components in appliances and equipment. Replacing existing equipment with advanced energy-efficient motors results in a substantial reduction in energy usage and cost.For today’s demanding applications that require increased electrical efficiency,EC (electronically commutated) fans represent a significant advancement in power savings technology, providing cooling and air flow solutions.

What Are EC Fans

EC fans are powered by brushless DC motors, which are also known as EC motors. Due to its inherent design that uses permanent magnets to generate a secondary magnetic field rather than copper windings, DC motors can be up to 30% more efficient than AC motors . Brushless DC motors are typically 85-90% efficient while brushed DC motors are generally in the range of 75- 80% efficient; the brushed motors lose efficiency from brush friction. The increased efficiency of the brushless motor means that less energy is lost as heat, while more energy is turned into rotational force and therefore power.

EC motors are controlled by external or onboard electronics that convert the incoming AC power signal to the DC voltage needed by the motor. The electronic circuitry performs the function of the mechanical commutation that switches the direction of the current and the magnetic field polarity to induce the motor’s rotation. As adjusting the power to the EC motor controls the EC fan speed, thereby improving performance, the design allows for more accurate and efficient motor control.

Why Use EC Fans

As long as the interface between the fan and the device is left unchanged, EC fans can be used in most applications where AC fans are used.When this interface is properly designed, EC fans can be used as “drop-in” replacements for AC fans. Compared to AC fans, EC fans are the same size while offering the same or higher airflow capacity — all with significantly less power.

Because they have built-in variable speed control a A large portion of the energy efficiency of EC fans occurs . Small reductions in the fan speed lead to large reductions in the power requirement, since the relationship between the fan speed and the power required by the fan is a cube function. Precisely controlling the fan speed to match the airflow demand of the application can result in substantial energy savings.

High efficiency EC fans have gained popularity and are being used in applications where there is a need to meet energy efficiency regulations, yet they offer other advantages as well. EC motors avoid the sparking and potential electromagnetic interference of brushed motors. They have longer service life due to the smaller heat losses and lower operating temperatures. The lower operating temperature means that the fan does not have to do extra work to remove wasted heat that is generated by the motor itself. EC motors offer a wide operating window of fairly constant efficiency over a range of speeds due to their variable fan speed control, when compared to AC motors, which tend to have peak efficiency at a single speed. In addition, EC motors require little to no maintenance and provide increased reliability. Since EC fans have lower operating costs, this leads to shorter payback periods for new equipment.

EC fans are ideal for use in major home appliances such as refrigerators, freezers, ovens, range hoods, microwaves, dishwashers and clothes washer-dryers.

Originally used only in high-end appliances, they are now used in high volume/mass market appliances due to their energy savings advantages (i.e., their higher efficiencies). Additional applications may include air conditioning units, heat pumps, furnace fans, dehumidifiers, beverage vending machines, automatic icemakers, commercial appliances, commercial chillers, duct fans for ventilation, condenser units and extraction fans for removing smoke and exhaust. However, the biggest uses for motor-driven elements in both the residential and commercial sectors are refrigeration and HVAC (heating, ventilation and air conditioning).

Market Requirements for Energy Usage

Government eco-design regulations and marketplace requirements for energy efficiency standards are driving design considerations, in the consumer appliance market.Energy efficiency has become one of the performance specifications for new appliances. The high electrical efficiency of EC fans aids in meeting these requirements.

In the U.S. market, the Department of Energy (DOE) is responsible for upholding the minimum energy efficiency standards for household appliances that were established in 1987 as the National Appliance Conservation Act. Under the Federal Trade Commission falls, labeling appliances with the ENERGY GUIDE, which lists energy consumption, efficiency and operating cost information. The ENERGY STAR label, a voluntary program under the Environmental Protection Agency, has even more strict requirements on energy savings. The Building Technologies Office of the DOE has outlined potential energy savings using EC motors in commercial and residential equipment.

While others are in process, some energy conservation standards have been established so far.

Examples of some of these standards are as follows:

  • Residential refrigerators and freezers – 76 FR 57516 (September 15, 2011)
  • Residential clothes dryers – 80 FR 16309 (March 27, 2015 – proposed rule)
  • Commercial and industrial fans and blowers – 81 FR 75742 (November 1, 2016 – proposed rule)
  • Residential mechanical ventilation system fans – 82 FR 2857 (January 10, 2017)

The European Union established two eco-design directives on minimum energy efficiency requirements. Directive 2009/125/EC extends the requirements for energy-related products (ErP) which help to reduce electrical usage, such as insulation materials, while Directive 2005/32/EC sets the requirements for energy-using products (EuP) such as household appliances.

Several energy conservation standards have been established, and others are under consideration:

  • Household refrigerators – Commission Regulation (EC) No 643/2009
  • Household dryers – Commission Regulation (EU) No 932/2012
  • Domestic ovens, cook tops, and range hoods – Commission Regulation (EU) No 66/2014
  • Professional refrigeration units (storage cabinets, blast cabinets, condensing units and process chillers) – Commission Regulation (EU) 1095/2015

Applications

Home appliances, those that operate continuously, such as refrigerators and freezers, provide the best opportunity for energy savings. Improvements on features such as seals and compressors, the usage of vacuum panels for added insulation, and the switch to LED lighting made some reduction in energy consumption for these appliances. The best opportunity for energy savings offers the use of EC motors and fans. Fans and motors are used both inside the refrigerator, to circulate air around the coils and maintain specified temperatures, and outside, to cool air around the condenser.

Range hoods provide another opportunity for using EC fans. While not in continuous operation, the function of a range hood, or exhaust hood, is to remove heat, steam, fumes, smoke, odors, grease and airborne particles in the area above a cooktop by means of an electric fan. To remove all these potential contaminants while not being so noisy that it is never used, the fan needs to be sufficiently powerful . In a more energy-efficient way EC fans provide both of these functions. As the appropriate fan speed can be selected as needed, Dual-speed range hoods provide even greater energy savings.

Washer-dryer combos and Clothes dryers (which, while more common in the European market, are growing in popularity in the U.S. market) are a third example of home appliances where EC fans provide a great benefit. To remove moisture from the clothing EC fans are used to bring hot air into the dryer . The humid air is either sent out through an exhaust vent or passed by a heat exchanger to remove moisture through condensation before more hot air enters the dryer. Increases in air flow performance are provided by EC fans, and this improves the energy efficiency of these appliances, while their lower noise level improves customer satisfaction.

Central air conditioning systems use several motors, one each for the compressor, the outdoor fan and the indoor blower. To circulate air throughout the ductwork a similar indoor blower is used in furnace systems. Replacing existing AC fans with more energy- efficient EC fans offers the highest potential savings due to the variable fan speed motor, although maximum energy savings can only be achieved if the entire system, including the compressor, is designed for variable speed. Also, running a furnace fan at a reduced speed may require it to operate for a longer time period, reducing some of the savings.

Summary

To meet the more stringent energy efficiency standards in place EC fans are being used in both the U.S. and European markets. EC fans can be used as drop-in replacements for less efficient AC fans, by maintaining the same interface between the fan and the appliance. EC motors can drive both axial and radial fans, as needed by the specific application. Orion Fans will be introducing a family of EC fans and blowers offering low power, dual speed, energy-efficient cooling solutions. Ranging in sizes from 60mm to 280mm, some of these EC series fans feature universal voltage input making them easy to design in for a wide variety of applications. Enabling customers to meet energy-consumption requirements from agencies like ENERGY STAR, they offer energy savings of up to 50%. Additional models and sizes of EC fans will be available from Orion Fans.

Healthcare – Reliability, Security, And Longevity Industrial Flash Memory

Medical applications require very high standards for safety and reliability. You need to address issues such as patient privacy and strict legal regulations.

Medical technologies should be fast, accurate, reliable, and compatible with connected devices to improve the quality of patient care and to avoid or minimize medical errors. In addition, healthcare applications require instant access to and retrieval of patients’ historical medical records so that doctors can offer the best possible treatment at the most convenient time, especially in critical moments when even milliseconds are important to saving a person’s life.

Cervoz (sales Karl Kruse) has various form factor flash modules that use superior flash ICs such as endurance MLC, reliability-optimized MLC and Powerguard functional products to ensure that the data can be processed correctly in real time to avoid life-threatening risks .

Flash module with DRAM buffer

The purpose of designing an additional DRAM chip in the flash module is to increase both performance and life.

Power:

A DRAM chip in a flash module has exactly the same function as a cache on a hard disk. While the flash module is operating, the controller throws small data into the DRAM chip to respond immediately. The DRAM chip acts as a directory that helps the controller assign data to the assigned positions. Therefore, it shortens the response time and increases the performance.

Endurance:

When comparing flash memory with DRAM, there is no restriction on the programming / erase cycles for DRAM, whereas this is the case with flash memory. Every time the controller tries to program a data sector in flash storage, it must erase an entire flash block before it is reprogrammed. However, the DRAM buffer can collect small amounts of data up to a certain amount before it is sent to the flash memory. This shortens the programming / erasing times for the flash chips and therefore increases the lifespan.

Reliability-optimized MLC (Cervoz Reliance Series)

“The Cervoz Reliance series uses their Reliability Optimized-MLC (RO-MLC) technology. Cervoz uses special firmware to control MLC NAND flash that uses only the strong sides of MLC NAND as memory. The technology is manipulated at the block level and the capacity of each block is cut in half by treating it as an SLC.
As a result, RO-MLC significantly improves its performance: data retention is increased five times, and most importantly, reliability is ten times higher than with conventional MLC NAND flash. RO-MLC offers higher density solutions at lower costs compared to conventional SLC NAND Flash and at the same time optimizes its reliability and performance, ”said Klaus Kruse Managing Director at Karl Kruse GmbH & Co KG.

This unique technology from Cervoz has made the Reliance series (RO-MLC technology) extremely high value for money, and the price is only twice that of MLC. In terms of return performance, data retention and reliability are more than twice as high (SLC is typically about four to six times more expensive than MLC). The Reliance series is a perfect solution for medical, semi-industrial and industrial applications that require moderate to high read and write cycles and at the same time require cost-effective solutions.

Powerguard (protection against power failure)

Powerguard is a PLP (Power Loss Protection) technology developed by Cervoz. The Powerguard function provides additional power during an unexpected power failure to complete the current flash write process and to protect the firmware and map the table integrity.

Cervoz develops the Powerguard flash modules with additional tantalum capacitors to save these additional charges. Take Cervoz Powerguard mSATA for example. The integrated tantalum capacitors are permanently charged with 12 V and keep the power supply as long as the data storage of the mSATA is still running.

Cervoz was founded in 2006 and specializes in embedded components for the demanding industrial PC market. Cervoz has been building our industry experience for over a decade. They know this industry very well and are therefore able to offer their high-quality embedded products with legacy and mainstream technology, long-term availability, parts list control, high reliability and maximum compatibility.

Cervoz offers various flash modules with RO-MLC technology, including 2.5-inch SATA SSD, CompactFlash card and CFast card.
Cervoz Wide Temperature Flash Modules support operating temperatures from -40 ° C to 85 ° C; Wide temperature DRAM modules support operating temperatures from -40 ° C to 95 ° C, which work flawlessly under extreme environmental conditions. Cervoz solutions can operate in thermal shocks and thermal cycles, making the products exceptionally durable in harsh environments. In addition, Cervoz wide temperature products offer excellent performance and low power consumption.

Cervoz develops these modules specifically for a variety of robust and industrial applications, e.g. B. for applications in the fields of factory automation, transportation, games, medicine and outdoor signage as well as military applications.
