Description: A 4-way cassette indoor unit that gives ultimate comfort with Wind-Free™* cooling.

Category: Cooling

Application: Samsung’s new Wind-Free™* 4-Way Cassette is designed to bring new levels of comfort to light commercial and commercial applications – even and efficient cooling without any cold drafts, thanks to the innovative Wind-Free™* cooling technology and optimized blade design.

Through over 15,000 micro air holes on the blades, cool air is gently dispersed and effectively maintains a comfortable level of coolness without the unpleasant cold draft.

This cool air flow, defined as “still air,” permeates softly and provides comfortable coolness throughout the room.

The Wind-Free™ 4-Way Cassette cools the room fast with Fast Cooling mode at the beginning of operation, and as the temperature drops to certain level, it automatically changes to Wind-Free™* mode to maintain the temperature set by the user.

Innovation: The Samsung Wind-Free™* 4-Way Cassette offers four unique benefits to its users.

1. Wind-Free™* cooling prevents cold drafts.
   One of the most common discomforts experienced by individuals in an air-conditioned space is a cold draft caused by direct, cold wind. Wind-Free™* cooling technology uses thousands of micro-holes on the 4-Way Cassette’s blades to evenly spread air without any unpleasant cold drafts. This calm, cool conditioned air created by themicro-holes is defined as “still air.” Once the set temperature is reached in Fast Cooling mode, the blades automatically close, but the unit continues to disperse air, which keeps noise levels to a minimum and self-regulates to create an atmosphere that is consistently comfortable and cool, but never chilly.
2. Even Cooling.
   Compared to traditional square cassettes, which forces air flow from 4 counter-directions, the Wind-Free™* 4-Way Cassette disperses airflow, virtually removing “dead zones” and uneven cooling spots.
3. Improved Cooling Speed.
   The optimized blade size and design of the Wind-Free™ 4-Way Cassette provides a wider cooling range, which cools the room quickly.
4. Motion Detection Sensor.
   The newly designed Motion Detection Sensor enables customized airflow direction, by allowing users to select the desired comfort level, and facilitates efficient operation by detecting the temperature and movements in the room.

Value: The Wind-Free™* 4-Way Cassette provides more value to users than other products in the same category by providing comfort in more ways than one.

Comfort that users feel is not only about cooling performance or energy efficiency of the unit. Factors like the time to reach the set temperature, air flow speed, and even distribution of cool air are also important. Ultimately, in addition to these features, the Wind-Free™* can provide comfort like no other product in the category, without uncomfortable cold drafts.

Market Impact: The key buying factors of traditional HVAC products have been cooling and heating capacity and energy efficiency. These factors will continue to be important. However, there are areas of discomfort with today’s air conditioning, and users have become somewhat used to it.

By introducing the Wind-Free™* 4-Way Cassette, we aim to satisfy users because they no longer have to deal with cold drafts. Samsung would like to apply the Wind-Free™* technology to our various home air conditioners to provide a comfortable environment to our customers. With Samsung’s Wind-Free™* cooling technology, we hope to push the boundaries of technology and innovation within the HVAC market.

*The Wind-Free™ unit delivers an air current that is under 0.15 m/s while in Wind-Free™ mode. Air velocity that is below 0.15 m/s is considered “still air” as defined by ASHRAE 55-2013 (American Society of Heating, Refrigerating, and Air-Conditioning Engineers).
