Based on meta-analyses of existing scientific literature, Seppanen & Fisk (2006) have developed models between ventilation rates
and work performance.
Concentrations of COCs were measured on February 21, 2017 after the HLR modules had been running for 8 months (initially deployed in June 2016) with reduced outside air ventilation rates
. Concenrtation levels are compared to LEED-recommended levels in Figure 8.
In order to establish ventilation rates
in sheep housing, outdoor temperature and relative humidity are usually employed as a reference .
Enhancement of the greenhouse air ventilation rate
under climate conditions of central Mexico.
With increases in temperature and humidity or decreases in the ventilation rate
, the release equilibrium concentration of formaldehyde from wood composites and the initial release rate will increase, resulting in a decrease in equilibrium time where all other things are equal.
In this present paper, a numerical model is developed for optimizing the phase change temperature for a PCM-based solar chimney by considering the amount of energy stored in PCM and ventilation rate
. Based on the numerical results, the following conclusions can be made:
Calculations of ventilation rates
: In each building, measurements were made in a vertical cross-section at six locations, which were representative of the location of the animals and the exhaust of the ventilation system.
We investigated a hypothesis that higher concentrations of C[O.sub.2], within the range found in buildings and without changes in ventilation rate
, have detrimental effects on occupants' decision-making performance.
The time between the produced repeated coughs decreased with the increase of the background ventilation rate
. The excess concentration of C[O.sub.2] over the background level was used as criteria for exposure assessment.
If the ventilation rate
is reduced the amount introduced indoors is relatively small, leading to low concentrations especially if the pollutants are of high adsorption characteristics (Yanagisawa et al., 1996).
This equation can be arranged so that the probability of airborne infection is given by P (infect) = C/S=1-exp(-Iqtp/Q), where C is the number of cases among S persons susceptible to the infection; I is the number of sources of infection; q is the number of "quanta," or units of bacilli necessary to cause infection produced per source per unit of time; t is the time of exposure per unit of time; p is the minute ventilation rate
of the exposed susceptible hosts in volume per unit of time; and Q is the volumetric rate of fresh air ventilation that removes the infectious aerosol in volume per unit of time.
