LITERATURE REVIEW 3.1 Literature Review The experimental analysis of a hybrid liquid desiccant dehumidifier system by Nanda Kishore. The desiccant chosen for the analysis is aqueous solution of calcium chloride. The effect of different operating variables on performance of both dehumidifier and regenerator are studied. The parameters studied are the effect of mass air flow rate, air inlet temperature, and desiccant inlet temperature. The practicability of dehumidification of supply air by the desiccant loop of the hybrid system is demonstrated [1]. A S Alosaimy is experimented to Concentration of desiccant solution regenerated by solar energy. Experimental results show that solution with 30% concentration can be regenerated up to 50% using solar energy. It was found that as the regeneration temperature was increased, moisture absorbing capacity of air was increased. As the regeneration temperature was increased, the dehumidification rate in the absorber was increased. The moisture removal rate was increased with the increasing in regeneration. As the inlet temperature of desiccant was increased, the dehumidification was reduced in the absorber, indicated the reduction in moisture removal capacity [2]. …show more content…
This paper is an experimental study on a structured packed tower of liquid lithium chloride dehumidifier system with different air velocity and flow rate of liquid desiccant. Desiccant temperature set into 100C and desiccant concentration is 0.4. The result of this study shows that averagely the moisture removal rate and the heat transfer rate are influenced both by the air velocity and desiccant flow rate. The result shows that high air velocity will obtain the fast air dehumidification but has low effectiveness and high liquid desiccant will obtain high
As you know the settlements of Jamestown and Plymouth were completely different with some similarities. The Jamestown settlement in the colony of Virginia, was the first permanent English settlement the New World. It had a defensive position and it was good for plantations. There were set backs to their settlement, such as poor Indian relations, which started when the troops raided the Indians villages, taking all that they please. Another setback was the diseases and starvation that caused people to become sick and then die. Over half of the troops died in 1609. Jamestown offered anchorage. Settled in marshy swamps were the climate was hot, humid, and mosquito infested. The settlers spent most of their time searching for non-existing gold

An experimental bench made up of original components from the air conditioning system of a compact passenger vehicle has been developed in order to check results from the model. The refrigeration circuit was
In Edgar Allan Poe’s story, “The Pit and the Pendulum,” Poe, uses the horror elements of isolation, madness, and plot twist to add suspense to the story. In the beginning, the narrator is standing in front of what he describes as judges as they decide his fate, which adds suspense because the audience doesn’t know what could happen to the narrator when the judges punish him. Secondly, he is all alone, or so he believe. He is the only one experiencing the things that are being done, he is isolated from everyone and it is very dark. The narrator thinks, “My worst thoughts, then, were confirmed. The blackness of eternal night encompassed me,”(Poe 3) as he lays on the damp ground. Towards the middle, the narrator going mad because the Spanish
Air conditioning is an everyday appliance used by all homes and businesses today. It works by utilizing a system of fans and heating/cooling element called ‘freon’ that comes in two types; R-22 and R-410a, R-410a being the newest type of refrigerant that has the advantage of being better for the environment. Despite this, R-410a is not as effective as R-22 in heating/cooling. Air conditioning installations also come in various sizes such as 2-5 ton installations. For instance, 2-ton units will be used in small homes and apartments. Larger 5-ton units will be used for larger installations such as warehouses and offices. Additionally multiple smaller installations could be used on one setup, like 3, 3-ton units being used on a warehouse, and
All major desalination plants in Australia incorporate energy recovery devices to minimize overall energy requirements. Also, a worldwide research and development effort is currently devoted to reducing the energy consumption of desalination processes. A report by CSIRO and WSAA has identified that the energy demand profile for water supplies was influenced by the uptake of desalination in Australian cities. “In South East Queensland, desalinated and recycled water made up around 10% of the water supplied in 2009/10. The treatment energy for these rainfall independent water sources made up more than 40% of the total energy for water supply treatment and pumping.”(Cook, Hall & Gregory

Desalination of sea and brackish water is a common technique to alleviate the increasing shortage of fresh water in many areas of the world today. Nonetheless, desalination processes require large quantities of energy. In addition, the cost of the different desalination techniques is very closely linked to the costs of energy. Therefore, in a context of continuously rising energy costs and with the impending exhaustion of the conventional energy resources, the development of energy- efficient desalination technologies is a very attractive and promising prospect to solve these problems.
The design project was about a desalination process making use of superheated steam from the solar system as electricity and using waste heat in the heat exchangers to produce pure water which can be used for domestic activities. Basic data was provided and some assumptions were made to aid the mass and energy balance.
Australia, as the driest inhabited continent, had installed 331 desalination plants supplying high quality water to the increasing population. Another country, China, also implete the use of desalination plants to tackle the drought and large population problems. This section will compare several technologies used in these two countries. As shown in Table 1, RO is the most used technology in both countries, accounting for 61.03% in Australia and 81.3% in China.
Heating, Ventilation and Air Conditioning system serves an important purpose in where we live or work. Whether we notice it or not it is providing us with clean air to inhale. Not only does the HVAC system provide us with fresh air, it also: maintains the flow of air to make sure certain areas are contamination free, eliminates contaminates before it is released to the atmosphere, protects equipment, and keeps us in a comfortable state.
Desalination, as a technique of its own, has its own overall negatives. It is known to require a large expanse of energy to start up and power the desalination plants. Consequently, this also results in it being extremely expensive since the majority of its current power sources are derived from the burning of fossil fuels. Thus it is not cost efficient nor is it always environmentally friendly.
Abstract: Life on our planet requires fresh water. According to WHO, water scarcity affects roughly one-third of the world’s population, and approximately 2.3 billion people. The World Water Council states that this water crisis will become more acute over the next fifty years as the world population increases. Yet, water covers nearly three quarters of our planet -- 97.5% of this water is saltwater. Therefore, a practical, economically viable desalination process is crucial to overcoming this crisis. A number of seawater desalination technologies have been developed during the last several decades to augment the supply of water in arid regions of the world. Due to the constraints of high desalination costs, many countries are unable to afford these technologies as a fresh water resource. However, the steady increasing usage of seawater desalination has demonstrated that seawater desalination is a feasible water resource free from the variations in rainfall. A seawater desalination process separates saline seawater into two streams: a fresh water stream containing a low
As day time is starting to become more and more unbearable, as fans would only constantly stir the hot sticky air S around, so the researchers ended up in choosing this topic. The researchers chose this topic mainly because of the hot weather here in the Philippines. The constant high temperature was the reason this came up to the researchers’ minds. This homemade air conditioner, also known as the “Swamp Cooler”, can help take the edge off and make a little more bearable. Not only that, but it’s also very inexpensive, easy to make, rather effective, and can
