How the Digital Inverter Compressor Has Transformed the Modern Fridge refrigerator in Ghana

How the Digital Inverter Compressor Has Transformed the Modern Fridge.For decades, Refrigerators or Fridges  had single-speed compressors that were always either off or on. A compressor is the engine that powers the refrigeration cycle, moving refrigerant through the inner and outer heat exchange pipes. With a single-speed compressor, when the temperature inside the fridge reaches above a certain temperature, the compressor suddenly switches on – a noise almost everyone is familiar with. The single-speed compressor operates at full power, producing enough cool air until the temperature has sufficiently decreased before abruptly shutting off.

Enter the digital inverter compressor (a compressor that can operate at variable speeds because it is operated with a digital inverter). Unlike the standard single-speed compressor, which is either off or operating at full speed (typically about 3,600rpm), the digital inverter compressor is almost always on, but can operate at different speeds – from 1,100 to 4,300rpm. This ensures high efficiency and consistent temperature inside the refrigerator. It also results in significant cost savings, a reduced carbon footprint, less noise and a longer lifespan for the compressor. The digital inverter compressor is one of the most important innovations in the history of Fridges and food preservation and Samsung has led the way.

Today, digital inverter compressors are the main technology used in Samsung’s signature appliances eg, air conditioners, washing machine & Fridges, including those that are part of the Chef Collection, the T9000, as well as food showcases and large-capacity premium Fridges. This has played no small role in Samsung’s ascent to become the world’s top refrigerator manufacturer.

In addition, Samsung has become a technical leader, as one of the world’s top manufacturers of this game-changing technology. Samsung produced more than 40% of the world’s digital inverter compressors in 2014 as other major manufacturers now use Samsung’s superior compressors in their Fridges.

Samsung really began its rise in this area in 1999 when the company pushed investment in BLDC (brushless direct current) inverter compressors. Since then, Samsung has continued to expand its investment in research and development, hiring a highly skilled team of researchers, which has enabled the company to remain on the cutting edge of technology. From 2000 to 2014, Samsung sold a total of 27.5 million BLDC inverter compressors, which are highly efficient and less noisy compared to a single-speed induction motor compressor. BLDC motors are also better in terms of reliability and longevity. The current Chef Collection refrigerator employs a fifth generation technology of BLDC inverter compressor.

The benefits are obvious. A fridge with a Samsung digital inverter compressor consumes up to 46.9% less energy than a single-speed induction motor compressor, and thus contributes far less in the way of greenhouse gases. Because the digital inverter compressor gradually speeds up and slows down, it does not have to work as hard to manage the temperature. This means that Fridges with digital inverter compressors suffer less wear and tear on components and are therefore far more durable than fridges with conventional compressors. This has allowed Samsung to offer a 10-year warranty on its digital inverter compressors.

The lack of abrupt starts and stops means no sudden, potentially startling disruptive noises interrupting your dinner. Digital inverter compressors are also far less noisy overall: up to 3 decibels quieter. And the consistent, uniform cooling that maintains the desired temperature means food lasts longer because changes in temperature can lead produce, meat, fish and dairy to spoil more quickly. It all means that consumers will save money on both their electric bills and food costs.

When Samsung sought input from its highly influential group of culinary experts, also known as the Club des Chefs, they emphasized that temperature uniformity is a crucial component of any fridge that may be used in a Michelin-starred kitchen. Chef Collection Fridges boast “Chef Mode,” which ensures that the temperature fluctuates no more than plus or minus 0.5 degrees celsius. The Chef Collection refrigerator is equipped with three evaporators and two compressors to control humidity. It is also made of stainless steel panels, which help to keep the temperature consistent.

Air Conditioners+Inverter Technology :Save Electricity

Air ConditionerS with Inverter technology

Have  heard about inverter technology ? Air Conditioners are a pain point for most people in our country who are concerned about their electricity bills. The moment an air conditioner is added to the list of appliances used in a household, the electricity bills increase significantly. Although it is difficult to significantly reduce the “big” impact of an air conditioner on your electricity bills, but still some of it can be managed by choosing the right technology, doing the right installation/maintenance/operation and by doing the right insulation of the room where the air conditioner is used.

When it comes to technology, there were not many available in the past. When BEE actively started analyzing and labeling the air conditioners, we got some good one in form of 5 star air conditioners. The latest and the most efficient technology that is available in market today is the Inverter Technology for air conditioners. Inverter technology is designed in such a way that it can save 30-50% of electricity (units consumed) over a regular air conditioner.

How does an air conditioner function?

For most people, an air conditioner just throws cool air at the temperature one sets it at. But does it really work that way? In principle, an air-conditioner during the cooling process, takes the indoor air, cools it by passing it through evaporator and throws it back in the room. It is quite opposite to how our good old air coolers used to work. Air coolers used to take outside air, cool it with water and throw it in. But air conditioners just work on internal air. Along with evaporator air conditioner also has a compressor that compresses the gas (refrigerant) in the AC to cool it that in turn cools the incoming internal air from the room.

In a regular air conditioner:
The compressor is either off or on. When it is on, it works at full capacity and consumes full electricity it is designed to consume. When the thermostat reaches the temperature level set in the AC, the compressor stops and the fan (in AC) continues to operate. When the thermostat senses that the temperature has increased, the compressor starts again.

Air Conditioners with Inverter Technology

The inverter technology works like an accelerator in a car. When compressor needs more power, it gives it more power. When it needs less power, it gives less power. With this technology, the compressor is always on, but draws less power or more power depending on the temperature of the incoming air and the level set in the thermostat. The speed and power of the compressor is adjusted appropriately. This technology was developed in Japan and is being used there successfully for air conditioners and refrigerators. This technology is currently available only in split air conditioners.

What is benefit of Inverter Technology?

Every air conditioner is designed for a maximum peak load. So a 1.5hp AC is designed for a certain size of room and 1 hp for a different size. But not all rooms are of same size. A regular air conditioner of 1.5hp capacity will always run at peak power requirement when the compressor is running. An air conditioner with inverter technology will run continuously but will draw only that much power that is required to keep the temperature stable at the level desired. So it kind of automatically adjusts its capacity based on the requirement of the room it is cooling. Thus drawing much less power and consuming lesser units of electricity.

Although air conditioner with Inverter Technology adjusts its capacity based on the room requirement, it is very important to install a right sized air conditioner in a room. Please make sure that you evaluate the room and air conditioner capacity before you make a purchase. Keep watching for this space as we are in process of creating a comparison for electricity savings in various air conditioners brands.
