Abstract: Effective provision of a comfortable indoor climate is a key requirement for modern central air ventilation systems. These systems play an important role in creating a healthy and comfortable environment for living, working or relaxing. Taking into account modern architectural trends and design solutions, linear louver diffusers are becoming increasingly popular as air distribution devices. Their aesthetic appeal allows them to be harmoniously integrated into interior design, often making them central elements that emphasize the style of the room. The design feature of linear louver diffusers lies in their specific structure: they have a small width with a significant length, which distinguishes them from traditional compact diffusers of round or square shape. This feature significantly affects the characteristics of the air jet formed by such diffusers. During the operation of ventilation systems in air conditioning or air heating modes, linear diffusers create unique air flows that differ from compact jets in their behavior, velocity and temperature distribution. These differences must be taken into account at the stages of design, adjustment and operation of ventilation systems in order to ensure their effective operation and achieve an optimal microclimate. Data obtained from computer modeling and experimental studies play a key role in the development and optimization of ventilation systems with linear louver diffusers. Modeling allows you to predict the behavior of air flows in different conditions, taking into account the geometry of the room, the location of the diffusers and air parameters (temperature, humidity, flow rate). Experimental studies, in turn, confirm theoretical calculations and allow you to refine the parameters of the system. Thanks to an integrated approach that combines modeling and experiments, it is possible to achieve high efficiency of ventilation systems, minimize energy consumption and ensure a comfortable microclimate in the premises. The use of linear louver diffusers also contributes to reducing noise exposure and uniform air distribution, which is especially important for residential and public spaces. Proper selection and adjustment of such diffusers allows you to avoid areas of air stagnation or excessive turbulence, which can negatively affect the comfort of users. Thus, taking into account the features of linear diffusers at all stages ‒ from design to operation ‒ is the key to creating effective and aesthetically attractive ventilation systems that meet modern requirements for comfort and energy efficiency.
