The ventilation in the barrier facilities was filtrated, and diurnal variation in room temperature and draught was minimal.
PMV-PPD, vertical air temperature difference and draught near the neck were calculated and compared for the four hybrid systems.
The thermal environment indices (temperature gradient and draught rating), indoor air quality indices (mean age of air, air change efficiency, CO2 and TVOCs concentrations distribution) and energy saving are analyzed and compared against each other.
Leave to rise at room temperature in a draught-free place for around 45 mins.
Two main exterior influence factors are wind and temperature: the higher the draught of outside air, the more pressure is put on the building hull leading to a higher air exchange rate through small gaps between walls and openings.
According to the analysis, the inlet air temperature in the up-draught drying zone (UDD) and blast temperature in the Preheating I (PH I) zone should be raised, and the length of the down-draught drying zone (DDD) should be properly increased.
The site tests demonstrated higher flue gas temperatures and stronger draughts than what specified for the EN standard tests.
This study investigated a number of factors influencing draught discomfort and temperature stratification in an office environment equipped with IJV.
Feed, refusals, and faecal samples were thawed at room temperature, dried in a forced draught oven at 60°C for 48 h, and ground to pass a 1-mm screen with a Wiley mill, following standard methods (AOAC 1990).
Key determinants for health and comfort in buildings are air quality, dampness, draught and indoor temperature, which are linked to energy efficiency via heating, ventilation, and insulation.
