Samsung Newsroom explored why this advanced air conditioning technology has been so well-received by global consumers.

▲ WindFree technology facilitates calmer, more comfortable sleep.

A recent Samsung survey² of 1,840 respondents from Brazil, India, Italy, Korea, Thailand and the United States revealed that 44.6% (820) favor WindFree air conditioning. More than half of these users (58%) selected “comfortable sleep” as their primary reason for choosing WindFree air conditioning. The results indicate that a growing number of consumers expect air conditioners to go beyond traditional cooling functions to offer options fit for any situation.

In addition, the survey showed that air conditioners are most used before and after bedtime. Nearly half (48%) of respondents use their air conditioners from 9 p.m. to bedtime, followed by 42% during sleep.

The advanced structure of air conditioners with WindFree technology allows airflow to be evenly distributed through 270,000 micro air holes.³ Once the room reaches a set temperature, the unit automatically switches to WindFree mode — gently cooling the space without the unpleasant sensation of cold air on skin — and creates optimal conditions for deep sleep.

“Energy savings compared to normal mode” was the second reason users preferred WindFree air conditioning. As energy savings gain interest in the face of climate change, the survey results indicate that WindFree technology addresses consumer demands for reduced electricity consumption.

In WindFree mode, electricity use is reduced by up to 77%⁴ compared to maximum cooling environments, offering substantial savings on electricity bills during peak summer months.

Additionally, respondents chose WindFree air conditioning to ensure “even cooling” (50%), “minimizing physical irritation” (48%) and utilize “AI automatic cooling” (44%).

WindFree air conditioner has received numerous international awards including top honors for the third consecutive year at the 2024 Korean Innovation Frontier Awards; the MCE Excellence Award at the 2024 Mostra Convegno Expocomfort (MCE), a leading global HVAC and refrigeration exhibition; and the Top Quality/Price award for the air conditioner category in 2022 from the German Institute for Quality and Finance (ITQF), one of Europe’s leading certification bodies.

“Since its debut in 2016, WindFree air conditioning has garnered significant appreciation from consumers around the world,” said Byoungha Song, Head of Air Solution Product Planning Group, DA Business at Samsung Electronics. “We will continue to provide innovative products that deliver personalized care to all of our users.”

Energy-saving rate is verified by Intertek, an international testing and certification organization, and may vary based on real-world usage.

Samsung Newsroom is taking a closer look to explore the stories behind Samsung Core Tech in this second installment. To unlock the full potential of every home, consumers require reliable, advanced appliances that boost convenience and eliminate hassle. Samsung has identified and answered this need with Core Tech, a philosophy comprised of four key themes — Outstanding, AI-Powered, Flexible Use and Durable & Sustainable. By introducing innovative technologies across its wide range of home appliances that follow these key principles, Samsung ensures that users optimize their living spaces and enrich their homes with unparalleled efficiency and ease.

WindFree: Cooling Redefined by Tradition

A prevalent pet peeve for air conditioner users is feeling a chilly breeze that is too strong when their units are running. To solve this issue, Samsung has developed a brand-new feature inspired by the traditional Korean practice of stone ice storage, known as seokbinggo. Essentially an ancient form of refrigeration, seokbinggo managed to keep items cool without cold drafts — making it an ideal source of inspiration for this new feature.

The WindFree air conditioner was successfully launched in 2015 after four years of extensive research and development. This ‘Outstanding’ piece of technology helps cool rooms gently and evenly by dispersing air through more than 23,000 micro air holes,¹ so users feel as if they’re floating inside a cool, comfortable cloud.

AI Cleaning: Meet the World’s First UL-Verified AI-Powered Cordless Stick Vacuum

A vacuum cleaner that works well on wooden floors but suddenly struggles when it’s moved on carpets results in an inconvenient cleaning experience. The Bespoke Jet AI, the world’s first UL-verified AI cordless stick vacuum cleaner,² relieves that kind of stress since it optimizes the cleaning mode according to floor types. But the question remains — how does this ‘AI-Powered’ stick vacuum determine what type of floor it is placed on?

The Bespoke Jet AI detects brush load and meticulously analyzes the data collected to classify floor type. Then, it automatically applies a smart algorithm to deliver the optimal suction power and brush roll speed³ tailored for the specific cleaning environment.⁴ The result is a clean carpet or a shining hardwood floor — ensuring peace of mind for users every time.

Auto Open Door: For Everyone’s Flexibility

Why do refrigerator doors sometimes refuse to open? The internal pressure of a fridge drops as it chills, generating a suction effect that resists users’ efforts to open the door. To make opening fridge doors a breeze, Samsung designed the convenient Auto Open Door⁵ feature.

Boasting 27 patents from seven countries, this innovation is a game changer for those who find opening fridge doors to be a challenge. Designed to be used with one simple touch this thoughtful feature helps make the refrigerator more accessible to a wider range of users. Created to enhance the ‘Flexible Use’ of home appliances, Auto Open Door also comes in handy when users have their hands full of groceries.

▲ Auto Open Door helps you open door with less effort by releasing the seal⁶ when you lightly touch them, enhancing accessibility and allowing for more ‘Flexible Use’

Less Microfiber Filter and Cycle: Reduce Microplastics in Drained Water

Microplastics pose a significant threat to ocean ecosystems, and around half a million tonnes of microplastics are released into the ocean from laundry every year.⁷

Samsung has consistently considered the impact of microplastics when researching advanced technologies and worked together with Patagonia. These dedicated efforts led to the introduction of the Less Microfiber Cycle in 2022 and the Less Microfiber Filter in 2023 – some of the latest additions to Samsung Core Tech’s ‘Durable and Sustainable’ category. Both the Less Microfiber Cycle and the Less Microfiber Filter help reduce microplastic emission in the rinse water.

Samsung has continued its efforts by providing the Less Microfiber Cycle update through SmartThings⁸ since this past August⁹ so users can easily download and run the cycle.

Samsung’s commitment to decreasing microplastics emission in the rinse water has gone noticed, as evidenced by the Less Microfiber Filter being recognized as one of TIME’s “The Best Inventions of 2023” in October.

▲ The Less Microfiber Cycle and the Less Microfiber Filter– some of the latest additions to Samsung Core Tech’s ‘Durable and Sustainable’ category – help reduce microplastic emission in the rinse water

Snoozing the Morning Away

▲ Sofas aren’t just for humans — every pet has a favorite napping spot on the couch.

The first thing I like to do after breakfast is take a long nap on the couch. For some strange reason, Delia likes to take a nap in the car while our owners run errands.

“Hey, it’s super fun to lean out the car window!”

Sometimes, we feel bad after naptime due to the amount of hair we leave behind. However, our owners are able to clean up after us with Bespoke Jet AI!

▲ Thank you, Pet Tool+!

Bespoke Jet AI features a dedicated Pet Tool+¹ made especially for animals like me. Thanks to its rubber nozzle and bristles,² the feature has been optimized to pick up thin, easy-to-miss pet hairs and can effortlessly cut up the collected hairs with its self-cleaning grinder,³ preventing tangling around the drum. Awesome, right?

What’s more, Bespoke Jet AI has this clever Battery Mix & Match feature that gives our owners the flexibility to switch between two types of batteries⁴ — large and lightweight capacity. Once they’re done cleaning up after me in the living room using the large battery, they can easily switch to the powerful, lightweight battery to vacuum the car seats after Delia is done shedding everywhere.

“Don’t forget All-in-One Clean Station that easily empties the dustbin, helping you clean to the end!”

Finding the Perfect Spot To Lounge in the Afternoon Sun

▲ Pets love stretching out on the living room rug. Those stains are a shame though!

The next thing on my to-do list is to find the “purrfect” spot in the house to soak in the afternoon sun. There’s no better feeling in the world! Delia likes to stretch out after a long walk too. Why does she need so much exercise?

“There are so many smells to discover! You should go out sometime.”

No thanks, I prefer rolling around on the carpet! However, we do tend to leave a lot of fur around, and sometimes even… a few stains. Oops! Luckily, Samsung has some dedicated laundry solutions to keep all our owners’ clothes and household fabrics clean and hygienic, meaning that my favorite blanket is always fresh, clean and ready for me.

▲ Pet Care Cycle will help with laundry.

Samsung’s Pet Care Top-Loading Washing Machine and Dryer⁵ feature built-in Pet Care Wash and Dry cycles specifically made for pet owners. Pet Care Wash improves rinsing performance by 2.6 times⁶ and removes 99% of allergens⁷ from us. What’s more, Pet Hair Filter removes six times more pet hair!⁸ Pet Care Dry then effectively removes over 97% of three types of unpleasant smells⁹ that us fluffy animals might leave behind on fabrics. These laundry appliances also hold bigger loads of laundry and come with SmartThings connectivity too!

Ending the Day With Well-Deserved Snuggles

▲ This sound from air conditioners is irritating!

At the end of a long day, it’s almost time for sleep — Delia and I love falling asleep with our owners.

“That’s right, Barry. Our family snuggles are my favorite!”

The room can get a bit warm when we sleep with our owners, so they turn on the air conditioner. But those regular air conditioners — they’re so noisy and always interrupt my sleep. Lucky for me, Samsung’s WindFree Air Conditioner¹⁰ has answers!

▲ WindFree helps both pets and humans sleep comfortably.

We hear that the WindFree Air Conditioner has 23 thousand micro air holes. WindFree Cooling ensures we stay comfortably cool with no unpleasant drafts and much less noise¹¹ as it disperses air through those holes. Not to mention, WindFree Good Sleep creates the ideal climate in our bedroom for sleeping!

Thanks to SmartThings Energy’s AI Energy mode, our owners can turn on the air conditioner for us when they’re away and reduce energy use by up to 20%.¹² Super cool, right?

(“Shhhh! Speaking of their absence, they can even watch me and play music¹³ through Jet Bot AI+.¹⁴“)

Special thanks to Barry and Delia for sharing their story this International Cat Day. Stay tuned to Samsung Newsroom to learn more about Samsung’s dedicated pet care solutions as well as the company’s latest leading home appliance technologies and features.

The DVM S2 features innovative technologies including a more advanced scroll compressor with Advanced Flash Injection (AFI) technology, an enlarged heat exchanger with optimized refrigerant flow, a multi-serration fan, and an enhanced power module.

The more advanced AFI motor control technology allows for a wider frequency range of 10~180Hz. The new low of 10Hz (compared to the previous model’s 14Hz) making the system more stable at low frequencies, leading to better WindFree performance for draft-free, comfortable temperature control. The new high of 180Hz ensures more powerful cooling performance.

Bigger Heat Exchanger and Multi-Serration Fan

Compared to the same capacity models in the current DVM S series, the heat transfer area of the heat exchanger in all the new models are significantly larger. The new unit’s hybrid path is designed to optimize the refrigerant flow corresponding to the airflow profile. Moreover, its unique multi-serration fan minimizes the turbulence of the air vortex, applying different serration, considering the air velocity of the edge and the inside of the blade, respectively. Moreover, the highly efficient Insulated Gate Bipolar Transistor (IGBT) reduces the loss of conducted electricity.

DVM S2’s new design is more aerodynamic and allows quieter operation, compared to previous generations. It has a more robust frame and reinforced structure with an upgraded exterior cabinet for reliability. The cooling operating range and external static pressure have been extended for flexibility in design, along with an upgrade on the emergency operation mode. Moreover, DVM S2 also features an on-device inverter check for better maintenance. Advanced technology for refrigerant sub-cooling control and installation condition analysis allowed for a smaller liquid pipe, which provides a 28% reduction in the amount of additional refrigerants used during installation compared to its predecessor.
