Abstract ：
The rapid development of photovoltaic technology provides more possibilities for the efficient application of solar energy in buildings. This research proposed a phase change material (PCM) heat storage wall system with a "four-layer" structure. A performance test platform using low voltage DC was built to study the mechanism of electric thermal conversion of the graphene electrothermal film and the heat transfer characteristics of the "four-layer" structure. As shown in the experimental results, under the voltages of 24 V, 32 V and 42 V, (1) with the increase in voltage, the temperature of the electrothermal film increases, while its electrothermal conversion efficiency decreases from 85% to 75%; (2) during the heat storage process, because of its latent heat storage characteristics, the temperature of the PCM wallboard is 3 similar to 5 degrees C lower than that of the cement wallboard, but the effective heat storage increases by 59 similar to 65%; (3) during the heat release process, the effective heat release of the PCM wallboard increases by 41-78%, and the maximum heat storage and release efficiency is 98%; and (4) at 32 V, the PCM can completely change phase. The theoretical calorific value of the electrothermal film is equivalent to the hourly power generation of 1.45 m(2) of photovoltaic modules. The results provide basic data for the integration of photovoltaic and phase change technology and their efficient application in buildings.

Abstract ：
The risks of cross-infection among occupants will be greatly increased by the high occupant densities and mobility inside and outside university classrooms. In order to know the distribution characteristics of culturable bacterial aerosols in such public environments, during normal didactic activities, indoor and outdoor bacterial aerosols were sampled from December 2018 to December 2019 by using Andersen six-stage impactor in 11 university classrooms. The yearly average concentration of outdoor bacterial aerosols was 314 +/- 229 CFU/m(3), and the size mainly distributed within 2.1-4.7 mu m. For unoccupied condition, indoor culturable bacterial aerosols were dominated by outdoors (R-2 = 0.78), the yearly average concentration was 254 +/- 130 CFU/m(3), and the size mainly distributed within 1.1-3.3 mu m. For occupied condition, the yearly average concentration of indoor bacterial aerosols was 494 +/- 263 CFU/m(3), and the size mainly distributed in the range of 1.1-4.7 mu m. With human presence, occupants instead of outdoor air becoming the primary source of indoor culturable bacterial aerosols. The seasonal emission rates of bacterial aerosols resulted from occupants were in the order of summer > autumn > spring > winter, corresponding to 1538 +/- 646, 850 +/- 292, 592 +/- 254, and 388 +/- 219 CFU/person/h. Air temperature, relative humidity, and PM10 mass concentrations were main environmental factors (p < 0.01) to positively influence the concentrations distribution of indoor culturable bacterial aerosols. The results can provide basic data for evaluating the risks of occupants expose to bacterial aerosols and improving indoor microbial air quality in university classrooms.

Abstract ：
The continuous methane emission from the coal piles is associated with many environmental problems and safety risks, in large storage facility. The methane emission parameters of coal piles and the concentration distribution characteristics of methane, which are the basis of ventilation design, are rarely reported in large storage facilities. In this study, based on the mass-transfer diffusion theory, desorption-concentration gradient method for deter-mining methane emission parameters of coal piles in large facilities is proposed. In this method, firstly, the coal pile methane diffusion coefficient was deduced by conducting the coal particles absorption-desorption experi-ments and the particle-size distribution. Then, combing the diffusion coefficient and methane concentration -gradient on the coal pile surface, the coal pile methane diffusion flux was calculated. Further, when methane diffusion flux was utilized as the source item for CFD calculations, the results were consistent with the onsite measured values, which demonstrated the accuracy of this method. The CFD simulation results show that methane has diffusion characteristics that adhere upward along the slope of the coal pile and converge on the coal ridge. The methane flow reaches the dome upwards, where a higher concentration is formed. Both the coal pile volume and the methane diffusion flux will affect the concentration distribution of methane in large storage facility. For a larger diffusion flux, the explosion limit will be exceeded, and measures need to be taken to eliminate the safety risk. These findings provide principal data and analysis guide for optimized design of ventilation performance in closed industrial building.
