Wildland firefighters work in unfavourable environments involving both heat and moisture. Moisture in clothing systems worn by wildland firefighters may increase or decrease heat transfer, depending on its source and location in the clothing system, location on the body, timing of application and degree of sorption. In this experiment, 4 outerwear/underwear combinations were exposed to 1 of 5 d...

Global temperatures have continued to rise for decades, partly due human-caused greenhouse gas emissions and subsequent urban heat island (UHI) effects. This current research examines the benefits of greenery by studying impact green roofs walls a building on thermal behavior transfer in warm humid climate. simulation study discusses importance greening systems improving comfort minimizing caus...

Performance of a gas turbine mainly depends on the inlet air temperature. The power output of a gas turbine depends on the flow of mass through it. This is precisely the reason why on hot days, when air is less dense, power output falls. The objective here is to assess the advanced systems applied in reducing the gas turbine intake air temperature and examine the merits from integration of the ...

Combined cooling, heating, and power (CCHP) systems produce electricity, cooling, and heat due to their high efficiency and low emission. These systems have been widely applied in various building types, such as offices, hotels, hospitals and malls. In this paper, an economic and technical analysis to determine the size and operation of the required gas engine for specific electricity, cooling, ...

Significant energy savings and thermal comfort improvement related to radiant floor systems may not be achieved when underfloor heating/cooling is adopted in lightweight building envelopes. Phase change materials (PCMs) are suitable candidates for providing the necessary inertia with a minimum effect on construction technology. Impacting variables like internal heat gains, weather conditions dy...

The study investigates a hybrid radiant cooling system's potential to achieve thermal comfort. (HRC) system combines the best features of typical all-air and conventional chilled system. An HRC presents advantages (a) reduce vapour condensation (b) adjust output by using an Airbox convector. three systems perceive comfort in predicted mean vote (PMV) between –0.5 +0.5 at 25 27°C. In room condit...

The present study focuses on the application of large-format thermal ceramic conditioning panels (TCPs) containing polypropylene (PPR) capillary tube mats in dwellings Mediterranean coast. and energy behaviours were examined once underfloor heating was installed, they compared with an alternative wall application. system implemented a single-family house located Spanish After having monitored d...
