Ahmedabad and parts of Delhi experienced the highest percentage decreases in NO2 during the lockdown as compared to their 2019 levels. It is possibly no coincidence that these cities have some of the highest number of registered vehicles plying on the streets in pre-lockdown times. What is ...
Fig. 7. Direct evaporative panel: (a) schematic diagram, (b) control volume of the panel (Shirmohammadi and Gilani, 2019). According to the analysis of several simulation results (Deng et al., 2011), the evaporative conditioning impacts on the air entering the GT significantly quantify and ...
Process models of these systems assume that they would operate at standard ambient temperature and pressure, when capture rates vary with ambient conditions, including temperature, relative humidity, and other factors. Here, we build an open-source model of a liquid solvent direct air capture ...
The impacts COVID-19 on the environment during lockdown conditions have been compared without lockdown conditions with respect to variable time duration and meteorological conditions. Particulate matter concentration of Chennai, Bangalore, Delhi, and Melbourne were assessed during the lockdown period. ...
In 2020, New Delhi's average annual concentration of PM2.5 in a cubic meter of air was 84.1, the study said, more than double the level of Beijing, which averaged 37.5 during the year, making it the 14th most polluted city in the world. Air pollution caused an ...
sampling rates (Rs) orkein situ using compounds infused prior to deployment [23], or adjust for environmental conditions mathematically [33], it nonetheless important to establish these parameters under consistent conditions for as many compounds as possible before developing environmental adjustments to ...
Air conditioning equipment refers to systems designed to maintain indoor temperatures below 30°C and provide adequate ventilation in workplaces or other frequently occupied spaces. AI generated definition based on: Environmental Requirements for Electromechanical and Electronic Equipment, 1999 ...
Benefits of leapfrogging to super efficiency and low global warming potential refrigerants in room air conditioning. Berkeley CA: Lawrence Berkeley National Laboratory report LBNL-1003671; 2015. Google Scholar [4] H. Yu, B. Tanga, X. Yuan, S. Wang, Y. Wei How do the appliance energy ...
Air-conditioning, the control of temperature, humidity, purity, and motion of air in an enclosed space, independent of outside conditions. An early method of cooling air as practiced in India was to hang wet grass mats over windows where they cooled inco
It is noted that in both Shanghai and Zhengzhou, the AOD in 2020 was somewhat lower than in 2019. This may be due to reduced emissions during the COVID-19 lock-down period in early 2020, leading to lower aerosol concentrations over most of China (see, however, e.g., [26,87,88,89...
