Even on Hot Summer Nights, Samsung’s WindFree™ Technology Ensures Restful Sleep

Samsung air conditioners equipped with innovative WindFree technology have received widespread recognition across markets around the world. Since launching globally in 2017, sales outside Korea have continued to grow with the average annual growth rate reaching 30.7%[1] over the past three years (as of the end of the first half of 2024).

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 survey[2] 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.”
