Air and nitrogen flow measurement in controlled atmosphere (CA) room
Transporting refrigerated perishable goods such as fruits and vegetables in Controlled Atmosphere (CA) is an economical solution for long distance shipments as well as long-term storage. The freshness of perishables is preserved by refrigeration and modification of the gas concentrations in CA rooms which provides reduced respiration (C6H12O6 + 6O2 à 6CO2 + 6H2O + Heat) of fruits and ...

Hourly NOx concentrations and wind direction in the vicinity of a street intersection
This study relates NOxconcentrations and wind (speed and direction) measured inside an asymmetric street canyon, with ambient wind. The monitoring site is located near a street intersection. The wind measured at the domestic airport located in the city, near the coast, has been considered as ambient wind. Wind direction at the monitoring site inside the canyon is mainly from the E, NE, W and NW ...

What`s the Best Air Pollution Control Technology for My Process?
Air pollution control equipment is not something that business owners address by saying, “Let’s do the right thing for the environment and install an oxidizer!” In fact, the scenario is more likely to be “We need to increase productivity (always a good thing!), but that will put us over our annual emissions limits. Do we know what we will need? Where do we start? Who can ...

Optimizing Data Center Cooling
Proper cooling in a data center environment has always been a critical system component. All computer systems generate heat during operation, and this heat must be removed for the systems to function properly. In this post we will be examining ways to optimize and improve data center cooling efficiency. Data Center Cooling The cooling solution in a traditional data center environment is a ...

Experiences in the modelling of traffic policy measures for ambient air quality management in Lithuania
This paper presents the application of the Integrated Transport Effect Modelling System (ITEMS) in the city of Kaunas, Lithuania, taking into consideration some factors such as existing vehicle fleet, traffic flows, and ambient air quality monitoring data. The objective of this study is to estimate the exhausts of CO, NOx, and SO2 released by motor vehicles in relation to predictive traffic ...

Area Monitoring: Diffusion Sampling
Indoor and outdoor gas hazards that exist in open areas are usually monitored using diffusion-type sensors. A diffusion sensor has no active sample-drawing system; diffusion sensors rely on the ambient air movement and pressure to deliver the sample to the sensing element. Diffusion-type sensors are a reliable and cost-effective way to monitor open area gas hazards. When installing diffusion ...
