The phrase "air flow ventilation" is correct and usable in written English.
It can be used when discussing systems or methods related to the movement of air, particularly in contexts like HVAC (heating, ventilation, and air conditioning) or environmental control.
Example: "The building's air flow ventilation system ensures that fresh air circulates efficiently throughout the space."
Alternatives: "air circulation system" or "ventilation airflow".
Another possible contributing factor to the higher perc levels found in some residential dry cleaner buildings is the existence of undesirable air flow and ventilation characteristics, especially in older buildings.
The results show that for low air flow rates displacement ventilation is more efficient than mixing ventilation.
9 Induced sputum was performed with a portable compressor nebulizer NA180 (Aspen, Buenos Aires, Argentina) with a disposable mask in a specially designed room at the Tuberculosis Clinic without a roof, with direct sunlight, and good air flow for good ventilation.
In addition, it is suggested that increasing vent size results in higher ventilation air flow rate but barely affects the attic heating load, and that both sufficient ventilation and insulation are needed to ensure the proper functions of the attic and its energy efficiency.
Many suggested applications of active noise control involve the presence of a background air flow such as in ventilation ducts, exhaust stacks and the radiation from turbofan engines.
The package was developed from the computational fluid dynamics (CFD) model EXACT designed for studying indoor air flow induced by heating, ventilation and air-conditioning system.
From an analysis of the current situation and the calculation of winter and summer thermal loads of the building and the ventilation air flow rates, the study shows some viable proposals having as objective: the reduction of the heat load of the building in summer, a better air exchange and overall a modernization of the plant expansion.
For those buildings the ability of different plant configurations to improve indoor thermal conditions was considered taking into account the influence of several parameters, like weather conditions, internal gains, thermal transmittance, ventilation air flow rate, etc. Simulation results are compared in terms of energy savings and thermal comfort.
The models fit the CFD data with R2 values ranging from 0.878 to 0.978, and predict that the optimum locations in terms of heat transfer are when the elements are positioned as close to the crown floor as possible (Sy and Ry→min. limits), where they come in direct contact with the air flow from the cabin ventilation system, and when they are positioned close to the centreline (Sx and Rx→CL).
