Modern buildings in cold climates, like Norway, may have simultaneous heating and cooling demands. For these buildings, integrated systems with heat pumps, as well short-term long-term thermal storage, are promising solutions. Furthermore, combining this system renewables aids the transition to future sustainable building energy systems. However, cost-effectively designing operating such a comp...

We present the results of a combined study of ASCA and ROSAT observations of the distant cluster Abell 2390. For this cluster a gravitational arc as well as weak lensing shear have been previously discovered. We determine the surface brightness profile and the gas density distribution of the cluster from the ROSAT PSPC and HRI data. A combined spatially resolved spectral analysis of the ASCA an...

the present research proposes and optimizes the performance of a novel solar-driven combined cooling, heating, and power (cchp) kalina system for two seasons—winter and summer—based on exergy, exergo-economic, and exergo-environmental concepts applying a non-dominated sort genetic algorithm-ii (nsga-ii) technique. three criteria, i.e. daily exergy efficiency, total product cost rate, and total ...

Taking a typical two-person office as the research object, indoor thermal comfort of radiant cooling-displacement ventilation air-conditioning, cooling-personalized air-supply and all-air air-conditioning were simulated studied, index properties was analyzed. It found that personnel activity area with had lowest air supply temperature, PMV PPD, speed met requirements. The effect human body is s...

The transpirational cooling of vegetation as a measure to mitigate outdoor air temperatures was investigated for a street canyon in the city center of Arnhem, the Netherlands for the meteorological conditions of an afternoon hour on a hot summer day during a heat wave with wind of speed 5.1 m s 1 at 10 m above ground and direction along the canyon. Computational Fluid Dynamics (CFD) simulations...

BACKGROUND/AIM In military services, emergency situations when soldiers are exposed to a combination of nuclear, biological and chemical (NBC) contamination combined with heat stress, are frequent and complex. In these specific conditions, usage of personal body cooling systems may be effective in reducing heat stress. The present study was conducted in order to evaluate the efficiency of four ...
