To understand the air pollution problem in megacities such as Beijing, field measurement investigating variation of NH3 and its association with PM2.5 chemical property was conducted from 25 November to 24 December 2013. The results indicated that daily concentration wintertime tended be high on days relatively temperatures low wind speeds. Affected by synoptic condition, showed a bimodal diurnal pattern, which peak at around 09:00 22:00 day. As sole precursor for NH4+, exerted significant...
Abstract. During the APEC (Asia-Pacific Economic Cooperation) Leaders' 2014 Summit in Beijing, strict regional air emission controls were implemented, providing a unique opportunity to investigate transport and formation mechanism of fine particulate matter (PM2.5). This study explores use vertical observation methods influence on PM2.5 pollution Beijing before during Summit. Vertical profiles extinction coefficient, wind, temperature relative humidity monitored at rural site border Hebei...
This study investigates the performance of a refrigeration unit by applying spray evaporative cooling system to an air-cooled chiller. Experiments are conducted in temperate monsoon climate region combining with Moreover, this adopts new gas–liquid two-phase swirl nozzle, which is independently developed and characterized high atomization quality low energy consumption. The experimental results show that power compressor reduced, while COP (Coefficient Performance) chiller increases 4%–8%...
A method of using condensate water to reduce the airflow temperature around air conditioner condenser and improve performance is presented in this study. The structure traditional split adjusted by changing installation direction fan adding disk-type atomization cooling element (ACE) outdoor unit. under four modes tested different environment temperatures. Four were named, i.e. original unit without ACE, with blowing mode water. used pre-cool incoming airflow, maximum reduction at outlet...
As a reliable waste heat recovery device, the high-temperature pump (HTHP) is increasingly used in industrial enterprises. The selection of refrigerant one most important factors to determine safe, reliability and economic operation HTHP. Starting from this perspective, simple new method based on characteristics extrema volumetric capacity coefficient performance was developed obtain appropriate composition binary mixtures. Then, working fluids including four mixtures with R245fa were...
Black carbon (BC) has adverse impacts on human health and significantly influences the global climate as one of major atmospheric heating contributors. These effects strongly depend microphysical properties BC. BC particles their distributions are mostly monitored studied by online refractory instruments, which account for with aerodynamic diameters <1 μm. During a field campaign conducted in beginning season Beijing, coarse (aerodynamic diameter >1 μm) were found to take up high mass...
The Yangtze River Delta (YRD) is one of the most developed and heavily polluted regions in China. Understanding origin fine particles necessary for policy making on air pollution control this region. However, current studies quantifying contributions from different emission source are limited, especially winter pollution. In study, field observations scenario analysis simulations were performed by using Weather Research Forecasting Community Multi-scale Air Quality (WRF/CMAQ) model to...
Phase change material (PCM) used in buildings can reduce the building energy consumption and indoor temperature fluctuation. A composite PCM has been fabricated by binary eutectic mixture of tetradecanol (TD) lauric acid (LA) absorbed into expanded perlite (EP) using vacuum impregnation method, its thermal conductivity was promoted aluminium powder (AP) additive. Besides, styrene-acrylic emulsion mixed with particles to form protective film, so as solve problem leakage. Thus, a novel panel...
