Understanding that this is a real worry for many consumers, Samsung Electronics works tirelessly to make its appliances more energy efficient. For example, Samsung’s Wind-Free Air Conditioner features Digital Inverter Boost technology, an energy-saving innovation that reduces the device’s energy consumption by up to 73% compared to traditional fixed-speed type air conditioners.¹

Furthermore, the Wind-Free Air Conditioner’s Wind-Free Mode can even cut energy consumption by 77% compared to the unit’s Fast Cooling Mode, even while at maximum output. Samsung Newsroom sat down with two Samsung engineers to learn more about the Wind-Free Air Conditioner and its revolutionary energy-saving technologies.²

Reducing Electricity Usage With Digital Inverter Boost Technology

Just as the water in a waterfall cascades from higher ground to lower terrain, so does energy move from high to low. Air conditioners that use compressor technology to lower temperatures have to reduce heat through a process that runs contrary to this natural flow of energy – which is why air conditioners conventionally require a lot of energy to function. “The compressor serves as a pump that circulates the heat, moving matter from a lower point to a higher point,” explained Principal Engineer Byoung-Ok Ahn. “This means that the unit has to consume a lot of electricity.”

To help users save energy, Samsung adopted an inverter compressor – Digital Inverter Boost technology – that can regulate its own revolutions per minute (RPM) to maintain its energy use at maximum efficiency.

A fixed-speed compressor will run at maximum speed until the desired temperature is reached, and will then turn off once this is achieved. If the temperature exceeds this desired rate after the first round of cooling, it will switch on again at maximum output to lower the temperature. This repeated on-and-off process is incredibly energy-intensive, and also creates a fluctuation in room temperature as cooling is turned on and off again.

Inverter technology is more efficient since it simply slows down once the desired temperature is achieved and then only has to speed up slightly once the temperature goes up again, meaning that energy consumption is reduced by up to 73%. This process results in less temperature fluctuation, meaning that users can enjoy a consistently comfortable room temperature.

“The bigger the difference between the room temperature and the desired temperature, the higher the amount of energy that is consumed when the air conditioner is turned on,” noted Ahn. “When we compare the accumulated amount of consumed electricity between the fixed-speed compressor and the inverter compressor, the inverter type is notably more economical than the fixed-speed type since the latter turns on and off repetitively.”

Ahn also provided a tip for getting the most out of your air conditioner. “The most efficient way to use an air conditioner equipped with an inverter compressor is to set the desired temperature at between 24°C and 25°C (between around 75°F and 77°F) and to keep it on continuously when using it. Samsung’s inverter technology performs powerfully and efficiently because the total flux of its motor is maximized and the motor has multiple poles. Furthermore, this technology reduces vibration and noise for user peace of mind.”

Enjoying a Comfortable Breeze at All Times

Often with air conditioners, once the temperature in a room has been reduced to the desired temperature, the continued airflow from the indoor unit can become uncomfortably chilling. Continuous, direct exposure to cold wind can dry out the respiratory system and affect user’s health, making them more sensitive to illnesses. Homes with young children or family members who suffer from respiratory symptoms may be wary about keeping their air conditioner on continuously.

“The Wind-Free Air Conditioner’s Wind-Free Mode was developed to alleviate this inconvenience. The 2020 version of this air conditioner features 23,000 micro air holes, which gently disperse the cold air evenly throughout a room. This way, users can enjoy a cool air stream without being directly exposed to cold wind,” explained Ahn. “Wind-Free Mode can even cut energy consumption by 77% compared to the unit’s Fast Cooling Mode, even while at maximum output.”

Another unique feature of Samsung’s Wind-Free air conditioner is its bigger inlet and fan which allow for more air to be drawn in at once. “The air conditioner’s fan, the diameter of which is 15% bigger than conventional fans, along with the optimized width and angle of the outlet, means that energy consumption is reduced by 10%. Furthermore, air is cooled down to the desired temperature even faster,” said Engineer Kilsoo Son.

The air conditioner’s inverter technology and its Wind-Free technology work together in a synergy that creates even higher efficiency when it comes to bring users comfort at home. Once the desired room temperature is reached with the air conditioner’s powerful and fast cooling technology, the unit switches to Wind-Free Mode, slowing down the speed of the compressor while keeping the air cool, comfortable and quiet while minimizing electricity consumption.

Changing Modes Automatically for Ultimate User Peace of Mind

As well as its inverter technology and Wind-Free Mode, the 2020 Wind-Free Air Conditioner features other innovative features designed to help reduce users’ electricity bills. The unit’s ECO Mode also reduces the air conditioner’s RPM by up to 35% of its regular rate to reduce electricity consumption if it detects that there are few people in the room or that the ambient temperature is low.³

The AI Auto Cooling feature learns users’ preferred temperature and creates an optimal operation mode. “The AI Auto Cooling feature will provide users with an optimal setting,” explained Son. “The more users use it, the more it learns about your preferences. I encourage users to use this feature often so that they can easily and automatically enjoy their favorite temperatures without having to flip through settings, wasting energy.”

Users can reduce energy consumption even more with SmartThings. Users can turn off their air conditioner remotely and keep track of their daily, weekly and monthly electricity usage with the SmartThings app. In addition, the ‘My Schedule’ feature of SmartThings lets users set their air conditioner’s operation time, mode, temperature and fan speed remotely.

A Better Future for All With Air Conditioner Innovation

Higher electricity bills are not the only concern when it comes to energy consumption – many consumers are also concerned about how their appliance usage can impact the environment. This is why Samsung strives to make all of its devices, including its air conditioners, more energy-efficient and sustainable for the future. “While we work to provide optimum air cooling solutions, we also strive to ensure that our leading technologies remain energy-efficient,” noted Ahn.

Son echoed this commitment to sustainability. “We will continue to work to develop air conditioners that provide maximum comfort to users at minimum cost while also having a positive impact on our environment, not just for today, but also for the future.”

Samsung Electronics Malaysia today demonstrated its Wind-Free wall-mounted air conditioner – the AR9500M air conditioner, integrated with its Wind-Free Cooling technology. This modern and innovative product is designed to cater to Malaysians who often face the problem of hot weather. With the new cooling technology, Samsung aims to provide Malaysian customers a cooler indoor climate and optimal energy efficiency without the discomfort of direct cold airflow.

To cope with the scorching heat, many Malaysians will turn their air conditioners on full blast and at its lowest temperature of 16 degrees to achieve fast cooling when they enter their room or house after a long day out. With this practice, a lot of Malaysians experience the problem of ‘air conditioning sickness’ – staying in the same room due to the strong air from the full blast air conditioner, and also the constant extremely cold temperature.[i]

Samsung’s AR9500M provides customers with the ideal solution by maintaining a comfortable room temperature, using Wind-Free Cooling technology to gently disperse cold air through 21,000 micro air holes. Wind-Free Cooling is a two-step cooling system which first lowers temperatures in “Fast Cooling Mode”, then, automatically switches to “Wind-Free Cooling Mode” which creates “still air” once it reaches the desired temperature. This approach can also reduce energy consumption by up to 72% compared to Fast Cooling mode.

“Unregulated thermal comfort can affect the well-being, morale or physical health of a person.[ii] With this understanding, Samsung strives to provide Malaysians with an innovative solution through our Wind-Free technology, which produces gentle air spread evenly throughout the room, maintaining a comfortable temperature, without any unpleasant direct airflow,” Jimmy Tan, Head of Consumer Electronics Business of Samsung Malaysia Electronics (SME).

Early last year, during the ASEAN Cooling Summit, a report resulted that air-conditioning systems claimed to consume 40 percent of the electricity in Southeast Asia by 2040 at the present rate of consumption.[iii] The increasing and ineffective usage of air conditioners could lead to the ‘overloading’ of the air conditioner, contributing to high electricity bills.[iv]

In line with energy-saving requirements, the AR9500M uses Samsung’s proprietary Digital Inverter 8-Pole with POWERboost technology, which generates fewer torque fluctuations – reducing the overall energy required while shortening the time needed for the compressor to reach its maximum speed (Hertz).  Samsung’s world-first digital Inverter 8-Pole compressor consumes only 32% of the energy used by conventional air conditioning models, saving 68% of energy usage. It maintains the desired temperature without having to frequently turn on and off, hence, create lesser noise (quieter), while being more durable and efficient.

Not only that, the AR9500M’s unique Triangle Architecture has a wider inlet which allows more air to be drawn in at once, while boasting the optimal width and angle of the outlet, extra v-blades, and large fan – 22% larger than previous models. The fast-cooling feature cools the air 43% faster. It also ensures air is cooled and expelled faster, farther, and wider – reaching every corner of the room.

Enabled with the Smart Control WiFi, the AR9500M can be controlled anywhere through Samsung’s Smart Things app. Users can remotely regulate the temperature, adjust settings, receive real-time updates about the air conditioner’s performance and daily energy usage, as well as troubleshoot solutions when a repair is needed. This is also part of Samsung’s commitment in introducing the smart living concept to Malaysian homes – to create a modern, fast and convenient, as well as innovative stay-at-home experience to Malaysian families.
