Dehumidifier Essay By: Kelvin Cheung 8.2
The dehumidifier helps reduce the amount of moisture and creates dry air of a certain area that this machine is being placed in, so this means that it can be used in many cities that are close to the equator. So the main issue which this technology can solve, are moist environments. And humid air can usually create moulds to grow on walls, and eventually make a person sick.
Possible effects and some examples are pain in stomach, heat stroke, asthma or other allergy symptoms. So this technology is really useful for keeping our homes clean and healthy. The dehumidifier has an incredible design which solves the main issue really well; most dehumidifiers have a fan compressor, reheater, compressing cooler coils, and a reservoir. And here are how these components are broken down into three individual steps to work together and solve the issue. Firstly, a fan from a dehumidifier collects and drags air (with large amounts of moisture) into the machine. Then, as the air is being brought through, it approaches a section of the dehumidifier called the cooled coils. These coils are designed to perform the process of condensation to drag moisture away from the air that is passing through. The moisture would remain on the coils and eventually drip into the dehumidifier reservoir. Finally, the air inside the machine would be reheated and exhausted back to the room.
Another benefit that the dehumidifier has, is that it can speed up the process of drying laundry. And laundry can be an issue during the most humid and moist of times for people who don’t have access to balconies. So they would be required to layout their wet laundries in their houses which can cause humid air to get even more moist with ...

...ogress, which is brilliant for the electricity bill. However, affording these type of Dehumidifiers does cost a lot. Not only electricity bill, but medical fee as well. With the dehumidifier being used, moulds can be prevented from being grown on walls and making us sick. Evaluating and referring back to the first factor of it’s cost; this can lead to both positive and negative impacts, which would be a big effect. The positive impact is that most Dehumidifiers are now eco-friendly and doesn’t take up as much electricity anymore. But this means that it would have to be sold for a higher price. So basically, the development of this technology hadn’t solved any economic problems at all because the cheap ones create higher electricity bill, and eco-friendly ones are expensive. This can be related back to society again. So this factor does have a huge effect on economy.
Slow Economic Recovery resulting in demand moderation of HVAC systems and leading to greater emphasis on energy savings: Global economic recovery has been sluggish especially in the US and Europe regions. This coupled with reduced incomes and high energy bills have impacted the overall demand for HVAC systems.
Environmentally Friendly Conditioner Replacing an older model with a high-efficiency, environmentally friendly, air conditioner can reduce home cooling costs and energy usage by 20 to 50 percent according to HomeAdvisor. A ductless air conditioner is one of these systems. These can cost up to anywhere between $500 to $2,000, based on size and performance. Also known as split systems, they individually regulate the temperature in rooms. Doing so is more efficient than central air conditioning. According to Angie’s List founder Angie Hicks, “A ductless air conditioner can cost about $1,500 to $2,000 per ton of cooling capacity” Switching to a ductless air conditioning system can save people 20-30 percent on their energy usage every month, meaning less output of emissions from electric companies. These units can also incorporate heat pumps for w...
According to Jason, “costs would fall if people adopt new energy-efficient technologies without a price hike in energy” (Shogren, 2004). A study done by Jaffe and his colleagues concluded that 20-25% of existing carbon emissions can be eliminated if people switched to fluorescent light bulbs, improved thermal insulation, more efficient heating and cooling systems (Jaffe, Newell, & Stavins, 2003). It all comes down to the consumers. Some of the energy efficient technologies are readily available but are still expensive. The driving force to efficient-energy technology depends on the changes of relative price. People will not want spend money on newer appliances especially if the prices are high, and if their current one still functions.
...plications affecting efficiency. More focus is necessary on the indoor environment in schools, day care centres, hospitals and nursing homes for elderly, because children, hospital patients and elderly are sensitive subgroups. There are a number of indications that the indoor environment at home is normally worse than in the indoor office environment. The population spends most time at home, and children are exposed at home for many years (National Safety Council, 2009). This suggests that improvements of the home environment may be a cost-effective to reduce the indoor exposure burden in the population. The link between indoor and outdoor air pollution should not be ignored, as most of the exposure to outdoor pollutants occurs indoors. Finally, the function of energy saving and climate changes for the indoor environment and SBS will be an important future issue.
What is desiccation? Desiccation is an extreme state of dryness. Dryness is when there is lack of moisture. This step is to remove all the moisture in the body. This is to make the body lasts longer and does not decay easily. According to Noble 1969, natron salt is used in this desiccation step. Natron salt consist of a mixture of sodium compounds. Thus, it has high drying properties. The whole body will be covered with natron salt. Packets of natron salt will also be placed inside the body. 35 to 40 days passed by to complete this drying step (O’Neill, 2015). The natron salt does not only remove moisture, it also dissolves body
High humidity hampers the body’s cool-down mechanism. When the outside temperature is near the temperature of the body, the body undergoes changes to cool down, one of these changes is sweating. However, sweat only cools the body when it is able to evaporate on the skin. Humidity creates a damp environment, which prevents the sweat from evaporating and the air from absorbing the sweat. This creates a feeling of heat and stickiness. This can create fatal situations, because the body temperature increases, leading to the body working excessively to cool down, causing the body to lose many necessary chemicals and the water of the body. When the body is dehydrated, the blood thickens, placing strain on the heart, because it must add pressure to pump the blood efficiently. This would also cause the body to overheat, which can lead to heat cramps, fainting, heat exhaustion, and heat stroke. Heatstroke is known to be fatal and is considered to be the most serious form of heat injury (AchooAllergy, 2014).
Air lite, for example, represents an eco-friendly technology advance by purifying the air around working like leaves on the trees, eliminating bacteria, mold, and functioning as a filter that eliminates toxic substances. It also reduces the energy consumption in about a 15-50% as it reflects the hot component of sunlight, avoiding that rooms overheat (EASME, 2017).
The factors for exponential growth for air-conditioning are the HVAC Market, energy, environment, communication, societal, political, preparing for the future, looking ahead, and the conclusion. Buildings of the U.S. use approximately 35% of the nation’s precise total of energy consumption. The worth of shipments by U.S. HVAC manufacturers was over $28 billion of 1996. Since there are 52,000 CHC chillers needed to be replaced among the U.S., there’s a large opportunity for new chillers, new technology for the HVAC industry. The ozone depletion is an international issue in which is currently being resolved. The 3rd world countries are still allowed to manufacture CFC’s. Illegal imports of CFC’S to the U.S. is a consistent concern. Many illegal imports are virgin CFC’s. Those whom have a political overtones are specifically the ones whom create a protectionism of local commerce, having a negative impact on those inside and out of the country.
ways. The use of electricity will reduces the usage of the earth’s resources such as gas and oil.
Air and vapour handling equipment needs to be in place to get rid of vapour in case of solvent being a health hazard.
60% of our body is made out of liquid and water is one of the most common liquids we know. We need water as humans but what if the water was contaminated and unclean, we would have a lot of diseases that would spread and cause death everywhere and so NASA created a water purification device and its job is basically the process to purify water. One of the main reasons NASA did this is because of their space programs. We could bring as much water out of our atmosphere but it’s not going to last for long because the water will get dirty and unsafe to drink. Water is used for a lot of things and the water cycle does not exist in outer space, so water purification is water cycle, but in a machine. The machine purifies polluted water or any contaminated water.
Desalination refers to the removal of salt. It is typically used in the context of saline water, particularly seawater. Desalination is an intricate process and there are multiple methods of approaching desalination; however, the most popular technique is reverse osmosis. There are various factors that must be considered when desalinating water, such as pressure and concentration. Desalinating water has been used for many purposes, whether it be providing drinking water for communities, a steady source of water for agricultural irrigation, or a decent quality steam for the pharmaceutical industry. In today’s world, desalination is becoming more widely practiced in a large scale.
Life changed immensely in the 20th century as air conditioning and refrigeration systems became more efficient and controllable. Air Conditioning and Refrigeration play important roles in providing human comfort, food processing, storage, and many other industrial processes. We chose this topic because our life would be difficult without AC and Refrigeration. This paper will talk about the history of air conditioning and refrigeration, the role of engineers in designing and building it, people’s life before and after air conditioning and refrigeration, and finally Applications in the area of achievements and future developments.
... tag, and lots of regulation in certain countries requiring factories to use one, it puts a lots of stress and increases cost on the factory operators, and might cause jobs to be cut in order to buy and operate the ESP. This might affect economic growth, but on the other hand the ESP will result in cleaner air, and this has increased the housing market price due to cleaner air (Rich 2011), which will help a sluggish economy, for example in the U.S.
This is a significant change in how society functions. Greenwood credits this change to the washing machine. Greenwood, Seshadri, & Yorukoglu, 2005. "It is reasonably simple to draw positive conclusions on the washing machines impact, and I will explain some of those. " There has also been some negative effects and some interesting social changes regarding cleanliness standards.
