In this paper, a versatile numerical method to determine the pollutant distribution of ventilation system with recirculation at steady state is proposed based on typical ventilation systems with accessibility of supply air (ASA) and accessibility of contaminant source (ACS).
The geometry of the slot is often expressed by the aspect ratio (AR), which is an important designing parameter of the room air distribution in ventilation systems.
Other studies have shown that resistant bacteria can linger in poultry farms' water distribution and ventilation systems and in reused litter.
Using each model, the propagation of the overpressure shock wave and the distribution on the ventilation system were verified.
The work is aimed at giving a better insight to crucial parameters as the contact thermal resistance, fin effectiveness of ceiling panels, mass flow rate, supply water temperature, thermal load distribution, fenestration and ventilation system effects on the radiant ceiling capacity and comfort conditions.
Then based on the visible simulations, the movement characteristics of diffusion, sedimentation and accumulation of dust particles were investigated under the action of the complex air flow, and the spatiotemporal variation of dust distribution was studied with hybrid ventilation system.
To determine appropriate gas control strategies and design optimal drainage boreholes, it is essential to understand the gas flow mechanisms and gas distributions in the goaf and the ventilation system.
To maintain the indoor air quality, it is critical to remove indoor contaminant by ventilation system with effective air distribution.
Forty-six tests are performed to observe the influence of parameters such as the mass flow rate, supply water temperature, fenestration and ventilation system effects and thermal load distribution.
In a pig production building, it is the ventilation system that influences the indoor air distribution significantly.
