CHAPTER 1 INTRODUCTION 1.1 Problem Summary and Introduction: 1.1.1Problem summary Consumption of electricity has increased due to large use of air conditioner. In domestic electrical equipment, Air conditioner consumes around 30-40% from the overall electricity consumption. In air conditioner, compressor consume most of the electricity from the total available power, mostly around 95%, as it takes care of both sensible load and latent load. Therefore some alternate option have to be made in order to lower down the load on the compressor. 1.1.2 Introduction Air dehumidification is an important operation process not only in industry but also in comfort cooling. Although many methods are available for this operation, liquid desiccant system …show more content…
(2006) Studied the Liquid Desiccant Dehumidifier with cooling capacity Using compression heat pump system. They have selected lithium Chloride as refrigerant. It was found that, the water condensation rate increases with increasing desiccant flow rate, air inlet humidity ratio and desiccant inlet concentration. It changes very little with air inlet temperature and desiccant inlet temperature 1.4.3 A S Alosaimy(Application of Evaporative Air Cooler Couplrd With Solar Water Heater for Dehumidification Of Indoor …show more content…
It was found that, desiccant minimum temperature was proportional to the humidity potential between the indoor and outdoor conditions (temperature and humidity). The experimental results were show the, calcium chloride solution with 30% concentration can be regenerated up to 48% using solar energy 1.4.4 Kishore and Dilip (2013 ) (Experimental Analysis of a liquid desiccant dehumidifier using aqueous calcium chloride solution) experimentally analyzed the liquid desiccant dehumidifier, in which Calcium Chloride are used as desiccant. It was used as desiccant. 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 1.4.5 Bakhtiar et al

This moisture can be the beginning of mold growth once the summer heat warms up the area the moisture is located. Secondly, excess moisture could be getting trapped in your filter. Your air conditioning filter should be changed monthly when it is under heavy load during summer, and by doing this you can avoid moisture from soaking into it and growing gunk. Rotten Eggs
Main Show Tank Calculation: The main tank has a radius of 70 feet. What is the volume of the quarter-sphered sized tank? Round your answer to the nearest whole number. You must explain your answer using words, and you must show all work and calculations to receive credit.
D-The patient arrived on time for his session. Reports being stable on his dose and denies any cravings/ withdrawals. The patient reports that his wife returned back to work and is happy about it to the point that she 's able to recover bit from her slip and floor during the Winter. The patient reports that everything is good and he 's in the process of obtaining a locking container box. The patient asked about the status of his take home bottle application as this writer informed the patient that it is pending.
As mentioned in the hypothesis, the prediction is that as the temperature increases towards the optimal, the rate of respiration will increase. As the temperature exceeds the optimal, the rate of respiration will decrease. The temperature of the environment can be varied by placing the respiration chamber under a temperature-controlled water bath/cooling bath. The temperatures that will be used in this experiment will range from 0ºC to 50ºC in 10ºC increments. Digital thermometer will be used to measure the temperature of air.
Congress argued that the Clean Air Act (CAA) use of its broad, authoritative statement made the Environmental Protection Agency (EPA) obligation to regulate greenhouse gases (GHGs). Congress amended the CAA so states cannot fail to attain the air quality standards established by the EPA. Since following new regulations it’s not an easy phase in the environmental business, the EPA has found themselves with a lot of lawsuits by states and industries. Since states and industries dispute the EPA’s policy decision, Justice Scalia will most certainly be involved in this discussion. Justice Scalia believes that at the executive level, there should some kind of policymaking involving a decision to perform a public liability.
The dehydration of 2-methylcyclohexanol takes place at the bottom of the Hickman still. As the Hickman still heats up within the sand bath, the products evaporate and travel higher up in the still where they condense into a liquid and fall within the collection ring, thus separating the product from the remaining water. Drierite (CaSO4) is also added as a drying agent to absorb any leftover water within the product. The purity of the product will then be analyzed with infrared spectroscopy, paying attention to OH peak if it is present. Chemical Reactions: Data and Observations: Material Volume Mol.
Freshwater is an essential commodity for sustaining human life on earth. Rapid population growth and industrialization, especially in developing countries in the recent past, have placed pressing demands for freshwater. In the developing world, many regions suffer from shortages of freshwater supply. Water is one of the most abundant resources on earth, covering three-fourths of the planet’s surface. However, about 97% of the earth’s water is salt water in the oceans, and a tiny 3% is freshwater.
The purpose of this experiment was to synthesize a Grignard reagent with 1-bromobutane and homogenized magnesium in anhydrous diethyl ether. This solution was refluxed in a flask connected to condenser and drying tube. As seen in the mechanism, maintaining a dry condition is important to avoid the Grignard reagent from attacking water, which will result in loss of the bromine. It is important to reduce the amount of moisture and water vapors to avoid destroying the Grignard reagent, which is essential to the synthesis of 2-methylhexanol.
Abstract The experiment was performed in order to compare the effectiveness of Simple and Fractional distillation in separation of solid impurities from liquid and liquids with difference in boiling point higher than 25⁰C. The distillation curves of both processes were graphed on each case and compared. The main source of possible error was discussed and the way to improve the experimental procedure was proposed. It was concluded that the Fractional distillation is more efficient procedure than Simple distillation in liquid separation. However, in case of separation of solid impurities from liquid or liquids with high difference in boiling points Simple distillation can be preferred.
The first ever desalination plant, which was used, was in United Sates of America during the mid-20th century (1955). How Do Desalination Plants Work? There are many desalination techniques; the thermal distillation, reverse osmosis and many more. Thermal distillation is one of the processes that make desalination (removing salt from sea water) possible.
Air conditioning is truly a modern marvel. It provides our families with comfort when the temperatures rise during the summer. For most of us, we don 't even think about the complex system at work that allows an air conditioner to perform it 's magic. However, there comes a time in every homeowner 's life when the magic stops happening, and its usually during the hottest, most inconvenient times. The good news is that not every air conditioner problem requires the expense of calling a professional HVAC Technician.
INTRODUCTION Water is a transparent and nearly colorless chemical substance that is the main constituent of Earth 's streams, lakes, and oceans, and the fluids of most living organisms. Water plays an important role in the world economy. Approximately 70% of the freshwater used by humans goes to agriculture. Fishing in salt and fresh water bodies is a major source of food for many parts of the world.
