Cooking effluents are one of the most important sources pollution in indoor and outdoor environment. Exposure to cooking oil fumes (COFs) can increase risk many diseases. A healthy environment an energy-efficient ventilation system kitchens urgently demanded. This review is concerned with current knowledge physical chemical compositions aerosols generated from typical processes as reported literature. It focused on effects fuel, oil, temperature, method, style other factors characteristics...
This study proposed a combined solar-assisted heat pump (SAHP) system that could operate in the serial mode or parallel mode. For this system, stable year-round operation be achieved without assistance of electric heating low-temperature pump. By analyzing balance equations, correlation SAHP for two modes switched was obtained, which provided theoretical basis optimal system. In addition, performance applied university bathroom Xi’an district investigated using TRNSYS. The results...
The indoor environmental quality of hot pot and barbecue restaurants has caused an increasing amount public concern. Hence, this study assessed the conditions ventilation systems in nine such Xi'an, China, by performing field measurements focusing on variations temperature, relative humidity, CO CO2 concentrations due to cooking style. results showed that test depended mainly fuel, method system. Boiling food soup (hot pot) raised humidity inside restaurants. However, without sufficient...
On the basis of modelling with similarity theory and by using Archimedes number, Ar, as similitude parameter, this paper analyzes air distribution a busbar corridor in hydropower station Particle Image Velocimetry (PIV) measurement technique. The measurements were conducted 1:50 scale model for nine different operating conditions, including three supply rates: 0.75G0, G0, 1.25 G0 heat release 0.75Q0, Q0, Q0 (G0 are design values). variation regularity conditions analyzed evaluated based on...
An assessment of Chinese charcoal barbecue restaurants was carried out to assess the impact ventilation systems on indoor air quality. This study focused temperature field, relative humidity field and concentration distribution. The environments sampled were related fuel heat sources mechanical exhaust system, especially local system. For most time, CO2 values did not exceed acceptable level. CO is main contaminant this kind restaurants. From data available we could find restaurant C3...
To evaluate the dispersion of a heavy gas, such as sulphur hexafluoride, with low Froude number in built environment, an experimental and numerical simulation study was conducted. The experiment carried out using seven different injection inlet configurations chamber. release rate found to have great effect on concentration lower part obstacle middle chamber could cause non-uniform distribution concentration, particularly due variations locations angles outlets. Additionally, simulations...
The combined mine backfill–geothermal (CMBG) system can be used to effectively extract geothermal energy by installing a heat exchange tube (HET) in the underground backfilled stopes of mines, which as supply for buildings mines and surrounding areas. efficient performance this strongly depends on thermal process between HET its cemented paste backfill body (CPB). In study, validated simulation model is established investigate CPB, nonuniformly distributed properties CPB are fully...
Cooking food in water or soup, such as hot pot, is a widely used cooking method China. This type of requires no oil and cooks at lower temperature, but that does not mean it produces fewer pollutants less harmful. There are few research studies on the emission characteristics mechanisms particulate matter emissions when eating pot (the boiling process), which leads to unreasonable design ventilation systems for this kind catering. In paper, effects different ingredients (including noodles,...
Downhole microseismic data has the significant advantages of high signal‐to‐noise ratio and well‐developed P S waves core component monitoring is event location associated with hydraulic fracturing in a relatively confidence level accuracy. In this study, we present multidimensional DIRECT inversion method for locations applicability tests over modeling based on downhole system. Synthetic inidcate that objective function can be defined as multi‐dimensional matrix space by employing global...
