However, even for minor chemical releases within the room itself, a ventilation rate
between 6 and 12 ACH (which may be considered high by today's standards) is not nearly enough to maintain safety.
Estimated mean ventilation rate
was over 40 l/s person, which seems to be high.
The quality of CPR metrics included average compression rate, compression depth (mm), ventilation volume (mL) and ventilation rate
, participant percentage of appropriate (as defined by the 2010 and 2015 AHA guidelines) compression rate, compression depth, complete chest recoil, and CCF%.
If you're unsure whether your ventilation rates
are high enough, ASHRAE 62.1 specifies minimum ventilation rates
that are optimal for IAQ.
The outside air dampers were open according to the VRP minimum ventilation rate
when the building was occupied.
Measurements were carried out under real working conditions at a ventilation rate
of 20.1 air changes per h.
The ventilation rate
calculation, which represents only the fresh incoming air (and no EATR air), must take the level of contaminant in the ventilation air and the EATR of the system into account.
Under the scenario II (Figure 3), the outside wind direction strongly affected the ventilation rate
compared to scenario I.
The main environmental factors, such as temperature, humidity, and ventilation rate
, which affect formaldehyde release from samples, were investigated in the environmental test chamber (HW-571, studio volume = 1 [m.sup.3]; Jinan Hong Wei Technology Co., Ltd.).
Figure 3 shows the stored energy and ventilation rate
for different PCMs.
In all of the poultry buildings, the ventilation control system was programmed relating bird weight to minimum ventilation rate
. A target temperature was assigned as a function of the age of the birds for the breeding period.
