Abstract ：
As an energy-efficient and high-comfort indoor environment control method, the rational application of airflow in modern buildings has brought renewed attention, especially in hot and humid areas. Chamber experiments were conducted to examine occupants' preferred air speed and its effects on thermal comfort in hot-humid climate, and the extended thermal comfort zone limit was obtained. Three temperature levels (26 degrees C, 29 degrees C, and 32 degrees C) and two relative humidity levels (40%-60% and 70%-90%) were set, achieving six experimental conditions. During each condition, thirty-six participants were sequentially exposed to two stages with still air and personal controlled stable mechanical airflow produced by electric fans, each lasting 30 min. Their sub-jective perceptions were collected repeatedly, and skin temperature was measured continuously. For the six conditions, the average preferred air speeds were estimated to be 0.53 m/s, 0.62 m/s, 1.06 m/s, 1.31 m/s, 1.28 m/s, and 1.48 m/s respectively. The preferred air speed at high humidity (70%-90%) was approximately 0.15 m/s-0.3 m/s higher than that at moderate humidity (40%-60%), and such difference increased with air tem-perature. Elevated air speeds may be used to offset thermal discomfort, as indicated by a 0.2 degrees C-0.5 degrees C significant decrease in the mean skin temperature and improvements in subjective perceptions. However, for extremely hot and humid conditions including 29 degrees C/85%, 32 degrees C/55%, and 32 degrees C/85%, the discomfort cannot be completely eliminated. When local control of airflow is provided to occupants, the acceptable operative temperature range could be extended by approximately 1 degrees C regardless of humidity, compared with that under near still air speed below 0.1 m/s.

Abstract ：
The unique marine climate can affect the applicability of typical meteorological year (TMY) methods, which has not been adequately discussed in previous research. Based on meteorological data of five islands of Dongsha, Xisha, Nansha, Meiji, and Yongshu in China, this study selected their respective TMY using four methods including CTYW, Danish, Festa-Ratto and Sandia. Then, the suitability of various methods in marine climate, low-latitude sea area, was evaluated through the deviation between TMY data and measured data, as well as the precision of the building energy loads. The conclusions indicate that TMY chosen through CTYW method exhibits the lowest deviations in predicting the monthly mean value of meteorological elements with an average NRMSE value of 2.98%, and the hourly value with a cumulative Filkenstein-Schafer (FS) value of 20.8. It was followed by Sandia method with NRMSE of 3.44% and FS of 21.7. Compared with the mean building energy loads calculated using long-term measured data, the result calculated based on TMY chosen through CTYW exhibits the lowest error rate, followed by Sandia method, with the average NRMSE values of 2.06% and 2.48%, respectively. In summary, the TMY chosen by CTYW has a reliable representativeness in long-term climate characterization and energy loads simulation for low-latitude sea areas of China.

Abstract ：
Corrosion of reinforced concrete in the high-salt atmospheric environment of coastal areas widely exists in practical coastal projects, which will reduce the durability of coastal buildings and metal equipment. In this study, the factors influencing coastal atmospheric salt fog concentration were studied by combining theoretical analysis and coastal measurements. First, a set of atmospheric sampling and processing methods for atmospheric salt fog particles was summarized and sorted. Through actual measurements in Sanya, the atmospheric sampling and processing method were verified, and more accurate coastal atmospheric salt fog concentration data were obtained. The average atmospheric salt fog concentration at the coast was 190 mu g/m(3), the maximum value was 343.18 mu g/m(3), and the minimum value was 48.49 mu g/m(3). Then, the influence of meteorological factors, such as temperature, humidity, and wind speed, on salt fog concentration was explored based on the measured data, and the functional relationship between various factors and salt fog concentration was fitted. Finally, a model of salt fog particles migrating inland driven by wind in the coastal atmosphere was deduced theoretically and verified by the measured data of atmospheric salt fog concentration at different sea distances. The results of this study provide a theoretical reference for the anti-corrosion properties of coastal buildings and metal equipment.

Abstract ：
In order to investigate the dehumidification strengthening effect of multichannel flat tube thermal effect and analyze its strengthening mechanism, a corrugated fins-multichannel flat tube based internally cooled dehumidifier structure is designed. The optimum dehumidifier flow type was determined and the dehumidification strengthening characteristics and thermal mechanism of the multichannel flat tube under different air and cold source conditions were experimentally analyzed. The results showed that the flow type B2 (air-solution countercurrent and water-solution countercurrent) had the best dehumidification performance. High-temperature and high-humidity environments can worsen the dehumidification strengthening effect of the multichannel flat tube and the effective utilization of cooling power, although high humidity has a stronger inhibitory effect, its inhibition mechanism is different. When the inlet air humidity is 25.8 g/kg, the dehumidification performance increases by up to 16.6%; Decreasing the inlet water temperature and increasing the inlet water flow significantly improved the dehumidification strengthening effect of the multichannel flat tube. Furthermore, the multichannel flat tube can eliminate 100% of total heat when the inlet water temperature is below 20.7 degrees C.

Abstract ：
In China, most houses are generally scheduled for municipal central heating systems in mid-November each year. This study aimed to investigate human responses to different residential thermal environment in cold climate. A field study on thermal comfort and adaptive behavioral adjustment was carried out in 34 buildings in six residential communities in Beijing winter from October to December 2019, comprising both transition period before heating and heating period after heating. Indoor environment variables were obtained through self-recording instruments and human thermal responses were collected by subjective questionnaires. The results demonstrated that the mean comfort temperature in transition was 21.8 degrees C, and it was 22.5 degrees C during heating. During the transition and heating periods, there were wide ranges of acceptable temperature, while the preferred temperature was within the range of 23.5- 25.0 degrees C and 22-26 degrees C, respectively. A reasonable explanation behind these differences might be occupants' psychological and physiological acclimation. Moreover, preferred behavioral adjustments of the occupants to improve comfort during two surveys were also investigated. These results will contribute to the design and operation of rational heating temperature in residential buildings. (c) 2022 Published by Elsevier B.V.

Abstract ：
Thermal decomposition behavior and kinetics of four kinds of Chinese heritage architectural wood were investigated by thermogravimetric analysis. Experiments were carried out in air atmosphere up to 600 degrees C. The thermal degradation process of historical wood involved a two-step reaction kinetics, consisting of a low-temperature stage (230-370 degrees C) and a high-temperature stage (370-485 degrees C). Distributed activation energies determined using Coats-Redfern method and the first-order model (O-1) have optimum fitness compared with nth-order model functions. The lignocellulosic components of white pine and red pine have similar thermal stability, spruce has the slowest combustion rate or best thermal stability, and the reactivity of charcoal and lignin with oxygen of nanmu was higher than that of other three types of historical wood. The activation energy of four historical wood species is lower than that of most fresh wood and varied from 75.10 to 83.39 kJ/mol in the first stage and 10.75 to 15.97 kJ/mol in the second stage.

Abstract ：
In northern China, district heating systems without terminal control typically serve thousands of end-users, thus inevitably some users suffer from insufficient warmth and others are overheated indoors due to hydraulic imbalances. This paper aimed to understand the indoor thermal conditions and the actual heating demand in low-quality centrally heated dwellings. The driving force of heating demand was analyzed based on a smartphone survey of 233 households in cold climates, and field measurements of winter indoor thermal environment and AC supplemental heating behavior were conducted in a sample of 13 cool dwellings. Logistic regression and heteroskedasticity-robust Ordinary Least Squares were adopted to assess AC usage patterns and driving forces of heating demand, respectively. New knowledge has been gathered regarding average temperatures of 17.4 degrees C and 16.8 degrees C in cool housing living rooms and bedrooms, respectively, outside the human thermal comfort zone. Simultaneously, intermittent and partial AC usage patterns induced by time and air temperature were observed in these cool end-users for the comfort. The average daily running time of AC devices was 2.0 h for the living room and 1.8 h for the bedroom. There were statistically significant base linking occupants' heating demands to education level, household income, tenure type, presence of children, thermal experience and heating system. However, it was not a significant factor for household size. In addition, a rebound effect of building energy efficiency improvements on the interior temperature was also noticed. The results of this study shed light on better and target-oriented residential internal temperature or heating system design for both thermal comfort requirements and energy-savings.

Abstract ：
The Coanda effect on jet flow can be solved effectively using the jet fan with a pitch angle in highway tunnels. In this study, the ventilation efficiency of the jet fan with a pitch angle in the range 0-12 degrees is tested using the computational fluid dynamics (CFD) method with experimental validation. The mean air age in volume (MAA-V) is applied to evaluate the ventilation effectiveness in the full space and clearance space of tunnel. The results show that the jet fan with a pitch angle can significantly alleviate vortices caused by the jet flow. The pitch angle of 7 degrees can provide a desirable compromise for MAA-V, found to be 13.62% and 20.67% younger than that of 0 degrees for the full and clearance spaces, respectively. Furthermore, the pressure-rise coefficient at different pitch angles is also investigated, and the maximum is obtained at the pitch angle of 7 degrees as well. Finally, the pitch angle of 7 degrees is determined as the optimal angle for the jet fan, which is of great benefit for improving ventilation effectiveness and saving installed power in highway tunnels.

Abstract ：
Background: Coronavirus disease 2019 (COVID-19) is primarily a respiratory disease that has become a global pandemic. Close contact plays an important role in infection spread, while fomite may also be a possible transmission route. Research during the COVID-19 pandemic has identified long-range airborne transmission as one of the important transmission routes although lack solid evidence. Methods: We examined video data related to a restaurant associated COVID-19 outbreak in Guangzhou. We observed more than 40,000 surface touches and 13,00 0 episodes of close contacts in the restaurant during the entire lunch duration. These data allowed us to analyse infection risk via both the fomite and close contact routes. Results: There is no significant correlation between the infection risk via both fomite and close contact routes among those who were not family members of the index case. We can thus rule out virus transmission via fomite contact and interpersonal close contact routes in the Guangzhou restaurant outbreak. The absence of a fomite route agrees with the COVID-19 literature. Conclusions: These results provide indirect evidence for the long-range airborne route dominating SARSCoV-2 transmission in the restaurant. We note that the restaurant was poorly ventilated, allowing for increasing airborne SARS-CoV-2 concentration. (C) 2021 The British Infection Association. Published by Elsevier Ltd.
