An air solar-driven open sorption system for comfort cooling is investigated experimentally in an indoor test facility. The main components of the are a solar dehumidifier and cold storage with desiccant. One operation cycle 36 h. On first day cycle, charged. At night charged on two, discharged. A material investigation undertaken to find most suitable desiccant both components, including sampl...

The objective of this study was to modify an existing liquid desiccant and indirect/direct evaporative cooling-assisted 100% outdoor air system (LD-IDECOAS) for humidification operation in winter. energy benefit the desiccant-assisted approach during LD-IDECOAS over conventional method with a steam humidifier evaluated through detailed simulation. enthalpy effectiveness values measured from lab...

Abstract Indoor thermal comfort significantly influences people’s health, happiness and consequently the output at workplace. Here, a systematic simulation study on conventional vapor compression-based building cooling system integrated with desiccant assisted dedicated outdoor air (DOAS) is performed using EnergyPlus software for warm humid climate zones. Impact of material in DOAS, load requi...

tillage and press wheel weight play an important role in seedling emergence, crop establishment and growth. an optimal combination of tillage implements and suitable press wheel weights should increase grain yield. this study investigated the effect of tillage systems and press wheel weights on dry land wheat (triticum aestivum l.) seedling emergence and grain yields in izeh, khuzestan province...

We find an explicit expression of the Tutte polynomial of an $n$-fan. We also find a formula of the Tutte polynomial of an $n$-wheel in terms of the Tutte polynomial of $n$-fans. Finally, we give an alternative expression of the Tutte polynomial of an $n$-wheel and then prove the explicit formula for the Tutte polynomial of an $n$-wheel.

Due to the direct utilization of thermal energy and possibility of using renewable energy resources, the interest of using desiccant wheels for air-conditioning application is increasing rapidly. The thermally driven desiccant cooling systems are environmental friendly and has a great potential to reduce the peak electricity demand. During the experiments the inlet and outlet parameters in the ...

There has been considerable research worldwide on desiccant-based air-conditioning during the past 30 years. The rationale for push this new focus twofold: (a) need to provide an alternative conventional refrigerative systems which rely heavily fossil fuels as their energy sources, and (b) better thermal comfort in air-conditioned spaces warm hot humid climates. A desiccant system consists of s...

Wheel wear has been a concern in the railway for several decades. Studying the form change of the wheel/rail contacts in particular railways consisting of sharp curves helps to identify the risk of severe or catastrophic wear to minimize maintenance costs in order to be competitive in the transportation business. In this paper, the wheel/rail contact was studied on the particular railways. The ...
