Effect of Fans’ Placement on the Indoor Thermal Environment of Typical Tunnel-Ventilated Multi-Floor Pig Buildings Using Numerical Simulation

open access: yesAgriculture, 2022
An increasing number of large pig farms are being built in multi-floor pig buildings (MFPBs) in China. Currently, the ventilation system of MFPB varies greatly and lacks common standards.

Static pressure and ventilation rates in rooms [PDF]

open access: yesJournal of Hygiene, 1950
The British Standard Code of Practice and other authoritative guides, recommend minimum rates of ventilation related to the size and use of rooms, and structural means for providing them. But the difficulty of measuring actual ventilation rates suggests that it is seldom done.

Study on combustion characteristics and oxidation kinetics of water-immersed coal under different ventilation rates

open access: yesMeikuang Anquan
The sudden air drying of coal samples during long-term immersion in water will increase the risk of coal spontaneous combustion, and then coal spontaneous combustion will occur.

Greenhouse Natural Ventilation Models: How Do We Develop with Chinese Greenhouses?

open access: yesAgronomy, 2022
Greenhouse technology has advanced over the past few decades in terms of environmental control (e.g., indoor temperature, relative humidity, and CO2 concentration). Ventilation is an effective way to adjust the indoor climate.

The Association between Non-Invasive Ventilation and the Rate of Ventilator-Associated Pneumonia

open access: yesDiseases, 2023
Ventilator-associated pneumonia (VAP) has significant effects on patient outcomes, including prolonging the duration of both mechanical ventilation and stay in the intensive care unit (ICU). The aim of this study was to assess the association between non-invasive ventilation/oxygenation (NIVO) prior to intubation and the rate of subsequent VAP.

Study on the Natural Ventilation Characteristics of a Solar Greenhouse in a High-Altitude Area

open access: yesAgronomy, 2022
The ventilation rate of a greenhouse is one of the major factors to consider when assessing its ventilation performance. Compared with plain areas, high-altitude areas have lower air pressure, thinner air, and stronger solar radiation, which in turn ...
