“…The deionized water was self-made in the laboratory. Peanut oil (Jinglongyu with density at 20℃= 0.9182 g/cm 3 and viscosity = 62.39 mm 2 /s) and rapeseed oil (Fulinmen with density at 20℃= 0.9154 g/cm 3 and viscosity = 83.10 mm 2 /s) from local market of Zhengzhou, China were used in the experiment.…”

“…COFs refer to a gas-liquid-solid three-phase mixture, mainly including water vapor, oil mist, solid particulate matter, volatile organic compounds, polycyclic aromatic hydrocarbons, heavy metals, and carbonyl compounds [2]. Studies have shown that COFs may cause irreversible damage to human health, such as mutagenicity, genetic toxicity, and carcinogenicity effects [3][4].…”

With the increase in air quality problems derived from the emission of cooking oil fumes, the oil fume purifier was widely installed in household kitchens to eliminate the oil fume. However, because of the great adhesion of the oil, the elimination efficiency of the oil fume purifier goes down and its cleaning difficulty goes up. To solve the problem, four reagents were chosen to fabricate the amphiphobic surface by immersion and chemical vapor deposition. The results showed that the surfaces modified by alcohol reagent, organic fluorine group resin reagent, and heptafluorodecyl trimethoxysilane were only hydrophobic, while perfluorodecanoic acid-modified surface was amphiphobic and its contact angles for water and peanut oil were 138.3° and 125.5° respectively. Therefore, perfluorodecanoic acid could be used to prevent sticking and recycle the condensate of cooking oil fumes on the stainless steel surface of the oil fume purifier.

“…Chinese cooking, which is characterized by stir-frying and braising, can produce large amounts of heat and cooking fumes during the cooking process, especially in Chinese commercial kitchens (CCKs), where there is intensive cooking equipment and a large volume. Cooking pollutants are not only harmful to the productivity and health of employees in CCKs [1,2] but are also a significant source of atmospheric particulate matter [3,4]. An efficient CCK fume exhaust (CCKEF) system is required to capture and purify pollutants to guarantee that the indoor air environment and outdoor emissions meet the relevant requirements of current standards [5][6][7][8].…”

A Chinese commercial kitchen fume exhaust (CCKEF) system mainly consists of a wall-mounted canopy hood, air duct and terminal electrostatic purifiers, the capture and purification performance of which should be guaranteed to obtain satisfactory indoor and outdoor air environment in engineering applications. However, few studies have focused on the operation performance of CCKEF systems. This study was aimed at providing a simulation method to investigate the operation performance of such systems. The simulation model of a representative CCKEF system was established using CFD software and validated with measured temperature, air velocity and purification efficiency with a deviation within 10%. The validated model was used to predict the indoor air environment and purification efficiency of the CCKEF system under different working conditions. The results showed that the temperature of transfer air from adjacent rooms had a greater impact on the thermal environment of the cooking area than the surface temperature of stoves. The exhaust air volume had a significant influence on both the indoor air environment and purification efficiency. CCKEF system was suggested to be operated at the optimum airflow according to the simultaneous coefficient of stoves as the energy consumption of the system can be saved by 3.75%.
