  • How conditions affect cookies and air pollution control solutions

    Chocolate chip cookies are one of my favorite treats. Butter, sugar, eggs, flour, vanilla, and, of course, chocolate chips. Combine the ingredients together and you get a delicious cookie. Somehow, using the same ingredients the cookies do not always turn out the same. Sometimes they are thinner and crispier. Other times, they are soft and chewy. After watching cooking shows, I have come to ...

  • The benefits of monitoring compressed air

    Compressed air is used in many manufacturing processes for many different reasons, from the actuation and control of pneumatic valves and cylinders to the operation of process machinery and tooling. It can also be used as a transport medium for bulk materials or as a purge gas. For all its uses it is nonetheless expensive. This is why, through detailed monitoring, a business can enjoy the ...

  • Environmental Impact does NOT equal risk

    Auditing the new ISO 14001:2015:  Environment Impacts does not equal Risk In recent transition audits, there has been one common misconception that I have seen repeated, and that is that environmental impacts are risks.  This is not correct.  Environmental impacts do not equal risk. Let’s start ...

  • A quick guide to oil analysis for engine test applications

    Reliability testing is a very important component of new engine development. Engineers need to fully understand and chart the engine lifetime performance under a variety of conditions before mass production may be considered. Many important performance data parameters are collected in real time through the many different types of sensors that are connected to the engine in the test cell and oil ...

  • Influence of the Stirring Mechanism on the Precision of the Fusion for VITRIOX GAS and ELECTRIC

    Introduction Homogenization of the melt is an important aspect of sample preparation for X-ray fluorescence analysis using fusion. Whether the fused bead breaks or remains mechanically stable after cooling, depends largely on the homogenization. Once a stable fused bead has been obtained, it is only possible to judge if the sample is truly homogeneously dissolved in the flux by way of ...

  • Thermal comfort study of air-conditioned university laboratories

    In tertiary education institutions, good indoor air quality (IAQ) provides a conducive environment for teaching and learning activities. A field study on the environmental conditions and occupants’ comfort was carried out in six laboratories at Universiti Sains Malaysia. The study evaluates the current thermal comfort conditions using objective measurement and subjective assessment. The measured ...

  • What`s cool about air conditioning

    Conservationists often mock Americans for their love affair with the car. But the air conditioner appears to be a growing rival for our affection. Twenty years ago only about one-quarter of US residences had central air conditioning; by 2005 it was up to 62%, according to the United States Census Bureau. ...

  • Valves in Water System of Heating Air Condition

    Common valves in water system of heating air condition include gate valve, globe valve and butterfly valve.   Gate vale For its moderate length, rotary adjusting rod and good regulating performance, gate valve is widely utilized in large caliber pipes.   Globe valve Globe valve is suitable for small caliber pipes for its long length, ...

  • Effects of meteorological conditions on concentration of air pollutants in Delhi

    Air pollution in Delhi is a serious environmental problem. In this paper, the effects of meteorological conditions on local air quality are quantitatively assessed by determining the relationships between concentrations of Suspended Particulate Matter (SPM), Respirable Suspended Particulate Matter (RSPM), sulphur dioxide (SO2) and nitrogen dioxide (NO2) with meteorological parameters on monthly ...

  • Exergetic performance of a cylindrical methane–air microcombustor under various inlet conditions

    The entropy generation analysis is performed on a methane–air cylindrical microcombustor. The combustor is studied under different fuel–air equivalence ratios and two different inlet velocities. The results reveal that entropy generation due to heat transfer has the highest contribution to the total exergy destruction. Besides, the chemical and mixing entropy generations have the next greatest ...

  • Model and experimental analysis of the dynamic behaviour of air conditioning plant pipelines

    This paper presents a model to describe the transmission of vibrations through the pipelines of automotive air conditioning plants. It is known that vibration propagating from the compressor to the other system components can affect both acoustical and structural behaviour. In this study a frequency domain description is purposed, using a transfer matrix formulation to study the pipe dynamics. ...

  • Self–tuning fuzzy PID decoupling controller for VAV air–conditioning system

    One of the most important challenges in nonlinear, multi–input and multi–output (MIMO) and time variant systems is designing a controller with acceptable performance. This paper focuses on design a new adaptive fuzzy PID decoupling controller, applied in the VAV air–conditioning system. In this approach, the PID parameters are adjusted by fuzzy rules. Diagonal matrix decoupling method is employed ...
