چکیده
Eleven phase change materials (PCMs) for cooling humans in heat-stressed conditions were evaluated their characteristics. Effects of packaging material and segmentation also investigated. Sample packs with a different type PCM (water- oil-based PCMs, gels, inorganic salts) or (aluminum, TPU, TPU + neoprene) investigated on hotplate. Cooling capacity, duration, power determined. Secondly, pack hexagon compartments was compared to an unsegmented version similar content. decreased whereas duration increased increasing melting temperature. The water-based PCMs showed >2x higher than other but relatively short-lived. flexible gels salts did not demonstrate plateau power, compromising potential. Using aluminum indifferent. Adding neoprene considerably extended while decreasing power. Segmentation has practical benefits, substantially lowered contact area therefore

Potential applications of phase change materials in concrete technology Dale
In internal curing, pre-wetted lightweight aggregates (LWA) serve as internal reservoirs to supply the extra water needed by the cementitious and pozzolanic components of the concrete during their hydration processes. Due to their porous nature and reasonably high absorption capacity, the LWA can also be filled with other materials, such as phase change materials (PCMs). In this paper, three po...
متن کاملEvaluation of Thermoacoustic Cycles for Cooling Applications
The most promising applications for thermoacoustic cooling are investigated from the perspective of the thermodynamic second law efficiency in this paper. A design optimization program interacting with the thermoacoustic simulation program known as DELTAE was developed. Then it was applied to two of the most common configurations for standing-wave thermoacoustic coolers in order to determine th...

This paper describes a framework for the design of microvascular polymeric components for active cooling applications. The design of the embedded networks involves complex and competing objectives that are associated with various physical processes. The optimization tool includes a PDE solver based on advanced finite element techniques coupled to a multi-objective constrained genetic algorithm....
متن کاملApplication of Phase Change Material (PCM) for Cooling Load Reduction in Lightweight and Heavyweight Buildings: Case Study of a High Cooling Load Region of Iran
The application of phase change material (PCM) for energy conservation purposes in the residential buildings was investigated in the present study. Two types of building in terms of materials as the lightweight building (LWB) and heavyweight building (HWB) located in a high cooling load demanding region of Iran were considered for the study. Different types of PCM from organic and inorganic cat...
متن کاملOff - Peak Cooling Using Phase Change Material
The electric utilities in the United States are faced with continued rapid growth in electrical demand. The traditional response to growth in demand has been the expansion of generating capacity. However , economic, environmental, and scheduling constraints will combine to make adequate expansion difficult, if not impossible, in the 1980's. This thesis examines load management as an alternative...
