Using inverter technology to save energy

Using inverter technology to save energy

The anomaly in Africa is that the searing temperatures make it imperative to have adequate cooling in place, but the inadequate power supply grid makes it extremely difficult to achieve this, writes George Ferreira, vice-president and chief operations officer at Samsung Electronics Africa.

Out of the 53 recognised countries on the African continent, 47% are currently facing an energy crisis.

The challenge therefore is to capitalise on what energy is available, by developing products that reduce dependence on the available power supply. Add to the equation the fact that increasing pressure is brought to bear on the Earth’s inhabitants to reduce energy consumption, in the hopes of balancing the currently skewed energy scales.

It is vital that all stakeholders play their role in contributing to the green drive to utilise alternative, renewable energy resources.

Together with this shift to green technology, consumers can also enhance existing product offerings to ensure that they have as little negative impact on the national grids as possible.

Samsung is proud of its environmental stewardship, and not only builds products specifically for the demanding African environment, but also considers the impact products will have on the global environment.

Inverter technology within the consumer electronics market is one way that the company is underlining its commitment to protecting the Earth. Inverters are frequency conversion devices that control electrical voltage, current and frequency.

Cool technology The Samsung Inverter air conditioner uses an inverter circuit to convert AC from the power supply into DC, and then to turn it back into AC.

During the second conversion, the voltage and operating frequency are changed, making it possible to set the rotational speed of the compressor and thereby regulate the air conditioner’s output.

Inverter air conditioners are 50% more economical to operate and produce less noise than conventional units. When switched on, the compressor in a conventional room air conditioner operates at full power to reach the set temperature.

When the set temperature is reached, it finely adjusts capacity to match any temperature changes. When the room temperature decreases or increases, the compressor starts up again at full power to cool or heat the room to the set temperature once again.

This is inefficient use of energy and means that the room temperature fluctuates by as much as 1,5˚C from the set temperature. Using Smart Inverter control, Samsung is able to ensure that the air conditioning system continues to operate at low capacity most of the time, meaning that there is no stopping and starting of the compressor.

This function contributes considerably to energy cost savings. The Smart Inverter technology is also used in Samsung’s DuraCool refrigerators. The digital inverter compressor in the bottom mounted freezer improves energy efficiency and cooling performance by automatically adjusting across five speeds of RPM in response to cooling demands.

As the demand for power in Africa continues to mount, immediate solutions to the issue are needed. Samsung’s Built For Africa initiative directly addresses energy shortage issues, while concurrently providing a means of reducing carbon footprints through energy-efficient product designs.

Care for the environment is then passed on to the consumers who can rest assured that they are playing an important role in reducing energy demand.
