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...

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...

Desiccant evaporative cooling systems pave the path towards energy and environmental sustainability in buildings especially; however, direct coolers such configurations result high water consumption. The application of modern computational intelligence tools, including artificial meta-heuristic optimization algorithms, can improve operational comprehension desiccant while addressing minimizatio...

due to climate changes in recent years, in order to attain comfort and convenience, demands for heating, ventilating, and air conditioning (hvac) systems have been increased around the world, which has led to increases in emissions and power. desiccant cooling systems (dcss) are designed and built to reduce moisture and power consumption, create comfortable conditions for people in a building, ...

In liquid desiccant systems, an operating strategy of mixing small fractions weak and strong solutions integrated with a closed-loop has drawn attention for its ability to improve the system energy performance. This study proposed passive heat-pump-driven liquid-desiccant (HPLD) air-conditioning experimentally analysed performances. Based on density difference between solution in absorber sump ...

Globally, multiple efforts are being made to develop active atmospheric water generation (AWG) or extraction (AWE) systems, particularly using direct air-cooling technology produce from ambient air. However, this legacy technique is highly energy-intensive; it can only be operated when the local dew point above freezing of water, and does not scale create enough offer solutions for most industr...

The research was to find the characteristics and obtain a jelly candy formula from bovine split hide gelatin combined with commercial gelatin.The materials used were gelatin, glucose, sucrose, citric acid, sodium benzoate, desiccant pineapple shield. Comparison of in T1= 16:0%, T2= 12:4%, T3=8:8%, T4= 4:12% T5= 0:16%, other ingredients percentage is same. results compared candy. Parameters obse...
