Research of device for air distribution with swirl and spread air jets at variable mode

Examining a device for air distribution by the interaction of counter non-coaxial jets under alternating mode

“…The necessary conditions are created by means of heating, ventilation and air conditioning systems, or, as they may be called collectively microclimate conditioning systems. In confined premises, different conditions are created in terms of temperature and humidity depending on their purpose [2,9].…”

“…When choosing the design of an air distributors, it is important to study the structure and characteristics of turbulent fan jets [2]. In the heat stressed areas, it is appropriate to apply air distributors that use the interaction of jets, which cover a variety of flat and convex surfaces.…”

“…In industrial areas with a monotonous character of work, constant parameters increase fatigue of employees and negatively influence their performance. One of the most effective methods of solving this problem is to create alternating in time parameters, in particular, air velocity and temperature in the working zone of production premises [2,3,10].…”

“…In this connection, there is a need for development of new structural solutions for air disribution, which would at the same time provide creation of the necessary microclimate and saving of material and power resources. A problem on the intensification of attenuation of parameters of an air flow due to the interaction of the counter jets has not been sufficiently studied and, as a result, is little used [1,2].…”

“…When choosing a method of air distribution, it is essential to take into account specifics of the premises, their purpose and design features, location and dimensions of heat sources, moisture and harmful gases, the level of requirements for maintenance of design parameters of the microclimate [2,3]. Small production businesses in Ukraine are widely developing.…”
