Gentle Wind / Soft Breeze Function (“Laminar Flow”, “Soft Breeze”) in Air Conditioners
Purpose and Features
The “Soft Breeze” (Gentle Wind) function is a wind-free cooling mode achieved through air redistribution via special perforated elements. This function is available only in cooling mode. Its primary purpose is to ensure uniform and gentle airflow without creating sharp drafts or noticeable air streams.
In this mode, the indoor unit uses vertical or angled perforated louvers positioned close to perpendicular to the main air stream. Air is directed through numerous micro-holes, forming a laminar, soft flow that remains comfortable even during prolonged exposure.
A variation of the function, Intelligent Air, directs cold airflow along the ceiling surface. In heating mode, warm air is directed almost vertically downward.
Operating Principle
When the Gentle Wind / Soft Breeze mode is activated, the following occurs:
- Perforated louvers or blades inside the indoor unit rotate to partially block direct airflow.
- Cooled air is redirected through a system of micro-holes, ensuring uniform airflow throughout the room.
- Temperature fluctuations and localized overcooling zones are minimized.
The result is smooth and comfortable cooling without strong air drafts, which is particularly important for rooms with children, elderly individuals, and during nighttime operation.
In Midea air conditioners, this technology is called Breezeless™, also known as the imperceptible flow system. It uses dual perforated louvers in the indoor unit. The outer deflector adjusts direction and angle, while the inner louver contains numerous holes of different shapes, sizes, and orientations. This design disperses airflow evenly, preventing concentrated streams. The hourglass-shaped holes create a compression and expansion effect, reducing pressure and turbulence, resulting in a softer, less noticeable flow. Depending on the selected mode — upward, parallel to the floor, or fully dispersed — the system adapts airflow to avoid direct contact with occupants while cooling or heating the entire room efficiently.
Samsung’s equivalent technology is called WindFree™, which ensures gentle, even airflow without direct drafts. Air is dispersed through 23,000 micro-holes, eliminating the sensation of cold wind. In addition to comfort, WindFree mode offers energy savings — up to 77% less power consumption compared to conventional cooling.
Activation Conditions and Control
The function is activated via the remote control or the air conditioner’s control panel. A dedicated indicator 
appears on the indoor unit’s display to confirm activation.
Repeating the procedure disables the function. While operating in Gentle Wind mode, airflow direction adjustment via Swing or Air Flow buttons is blocked until the mode is turned off.
Technical Implementation
The Gentle Wind function is implemented using:
- Perforated guide elements with a drive mechanism;
- An automatic airflow distribution system;
- A built-in algorithm that limits airflow speed and direction.
The compressor’s performance level is not altered in this mode; the primary modification is to airflow, making it softer and more evenly distributed.
Advantages of Gentle Wind
Main benefits of this mode include:
- No direct air stream;
- Reduced risk of colds and overcooling;
- Comfort during prolonged stays in the room;
- Lower fan noise levels;
- Improved energy efficiency through optimized airflow distribution.
Limitations and Usage Conditions
This function is available exclusively in cooling mode. It cannot be activated in Dry mode, heating mode, or automatic regulation mode. Manual adjustment of deflectors and airflow direction is disabled until Gentle Wind mode is turned off.
Conclusion
The Gentle Wind function is a technological solution designed to create a wind-free, gentle indoor climate. It is particularly effective for individuals sensitive to air currents and for situations requiring long-term occupancy in cooled environments. By evenly distributing air through perforated louvers, the system maintains stable temperature and high comfort levels without the risk of overcooling.
