...Simulation of room air conditioning strategies for hospital operation theatres KARTHIKEYAN P, MURALIDHARAN K, ANAND SAMUEL Department of Mechanical Engineering, Vellore Institute of Technology, Deemed university, Vellore, Tamil Nadu, Pin code-632014. INDIA. Abstract: Hospitals have not always been fully air conditioned, except for new buildings in urban areas where ambient noise and atmospheric pollution necessitate having closed, double glazed windows. Air conditioning has been restricted by economic considera¬tions and has been confined to places where it was essential, for example operating theatres. Many operating theatres have been air-conditioned using conventional methods of turbulent air distribution but, as with clean rooms, this proves unsatisfactory in the prevention of airborne contamination. This paper emphasizes different types of air-conditioning strategies, their advantages and disadvantages in the case of operation theatres. It also brings out the impact of computational fluid dynamics codes in Indoor air flow simulation. Keywords: Operation theatres, Air conditioning systems, operating room air distribution, Room air-conditioning strategies, Air- quality & computational fluid dynamics. 1.Introduction There are three sources of bacterial contaminations: the supply of air to the theatre; the surgical team; and the emissions of bodily vapors and organisms from the patient. To deal with these and to prevent turbulent air movement and convection...

...Thesis Proposal Air-conditioning Systems Simulation and Energy Saving and Economic Analysis for Waiting Hall of Tianjin Railway Station Introduction Energy saving of buildings is ever-increasingly emphasized by modern society. With the emergence of innovative technologies, new materials, and sophisticated architectural design, designers are hard to know the energy consumption of a building. It will reduce the real meaning of building's energy consumption test if we conduct this test on a building already built. Therefore, it is recommended to simulate a building's energy consumption within project design stages. Owing to the complexity of the air conditioning process and the mechanism of thermal components, the work of analysis and computation is time-consuming. Meanwhile, simulation software advantages over the traditional way in the application of design compare and equipment selection. In a nutshell, building energy simulation softwares play a vital role in the analysis of building energy consumption. Tianjin Railway Station is the main railway transport hub of Tianjin city. With the help of software to simulate its air conditioning system and conduct energy analysis, we can obtain some salutary design advices, which are beneficial to the energy saving of Tianjin Railway Station. Introduction to Waiting Hall of Tianjin Railway Station Tianjin Railway Station is located in the center of Tianjin, at the junction of Heping District, Hedong District...

...Air conditioning systems can be categorized according to the means by which the controllable cooling is accomplished in the conditioned space. They are further segregated to accomplish specific purposes by special equipment arrangement. In selecting a suitable air conditioning system for a particular application, consideration should also vent to the following like system constraints such as cooling load, zoning requirements, heating and ventilation. Architectural Constraints depended on size and appearance of terminal devices, acceptable noise level, Space available to house equipment and its location relative to the conditioned space, and acceptability of components obtruding into the conditioned space. Financial constraints including capital cost, operating cost, and maintenance cost. There are four basic system categories of air conditioning namely central chilled water air conditioning system. An all-air system provides complete sensible and latent cooling capacity in the cold air supplied by the system. Heating can be accomplished by the same air stream, either in the central system or at a particular zone. All-air systems can be classified into 2 categories namely single duct systems and dual duct systems. The single duct system as shown in figure 1 is used for a large room such as an atrium, a banking hall, a swimming pool, or a lecture, entertainment or operating theatre. It can be applied to groups of rooms with a similar demand for air conditioning, such as...

...Christopher Burge Global Warming Global warming is a grave issue that is affecting not only the United States, but the whole world as well. Various international strategies need to be implemented so that these issues can be tackled. If taken seriously, the issue of global warming can not only be overcome, it can be prevented as well. Poll conducted in my community- family members, friends, and coworkers- asking if they felt whether or not global warming was a problem or not or undecided: Two examples of how global warming if affecting the life of our communities: * Global warming is already leading to more violent storms and less predictable weather patterns. According to the Pew Center on Global Warming, since 1995, only two years have not had above average hurricane activity. The overall number of tropical storms has not increased, but there are more storms strong enough to be called hurricanes. We will probably continue to get bigger storms, which will do more damage to coastal areas. * Global warming will have drastic effects on local ecosystems. Most plants and animals are adapted for a certain environment. Generally, each species does well when the temperature is in a certain range, and the seasons work in a regular way. As things like temperature and seasonal precipitation shift, less robust plants and animals are not going to be able to adapt quickly enough. This will result in widespread extinction. Three facts that are relevant to global...

...Chrysler AC Evaporator Core If you have an AC evaporator core failure in your Chrysler vehicle you're not alone. A quick search will reveal thousands of drivers dealing with the same exact problem. The scope of the air-conditioning malfunction is amazing. Evaporator core failure on a 93 Dodge Intrepid is as common as it is on a 2007 Dodge Caravan or a 2001 300M luxury sedan. One thing these models have in common is a high cost to replace the difficult to access component. On some auto repairs you can save money by going to a privately owned shop instead of a dealership. However, nobody wants to replace the evaporator on a Dodge or Chrysler product. Therefore, both independent and dealership shops will come in at a high estimate. They’re...

...It all began right after I checked in for my flight, I walked towards the gates and was about to enter the line. I was ready to go through the security screening and suddenly my anxiety crept up on my out of nowhere; “Are they going to strip-search me?”. My hands began to shake, “I couldn’t risk it.”, I thought to myself. I quickly popped the xanax pill in my mouth that my roommate gave me and got in line. You see, I’m absolutely terrified of flying. Have you ever been through turbulence? It’s no joke! My roommate was aware of my fear of flying, so he kindly offered me a xanax pill to help calm me during the flight. He told me, I would “blackout” and then I would be fine. But suddenly it hit me that maybe I couldn’t take it in through security and that's when the anxiety hit me. As walked closer towards the gate, I couldn’t help but notice all the security guards; were they looking at me? It felt like they were giving me the mean mug and I began to ask myself, “Why are they looking at me?”. Then I began to get paranoid -I forgot to mention that I ate a weed brownie an hour before all this and it was in full-effect. Now I was truly beginning to freak out! I am not sure how I managed to keep it together, but I finally got to front and put my bags on the belt for screening. I walked through the metal detector, but quickly noticed my bags didn’t. The officer told me there was a “red flag” and they needed to go through my bags. My face quickly became as pale as a ghost, even...

...The issue in this case is to assess Phillip’s taxable income for the year ended 30 June 2010. According to section 4-15 Income Tax Assessment Act 1997 (ITAA 1997), taxable income equals assessable income (Division 6) minus deductions (Division 8). Assessable Income In order to determine the assessable income, Division 6 of ITAA 1997 would be the relevant legislation and in particular Section 6-1(1) refers assessable income consists of ordinary income and statutory income. - Rental Income Section 6-5(1) defines “assessable income” to include income according to ordinary concepts. In the case of Adelaide Fruit & Produce Exchange Ltd, ordinary income is characterized as exhibiting recurrence and regularity. For Phillip’s case, rent falls under income from property as it exploit the property and considered to be income producing. Whereas Adelaide’s ruling for periodic and regular payment is satisfied by which a tenant contracts to pay the landlord, Phillip, for the use of premises. Hence, rent income of $55 000 is assessable under Section 6-5 ITAA 1997. However, $5 000 rent received on 5 July 2010 is not included since the case is only calculating for year ended 30 June 2010. - Manufacturing of tennis racquets business Section 6-5 ITAA 1997 defines “business” as sustained and regular transactions and transactions done in the course of carrying on a business. This is satisfied by the manufacturing of tennis racquets where it regularly manufacture and...

...Airwide International case study solution Summary: The executive team of the England based top supplier of commercial and residential air conditioning systems in Europe have gathered in London to wrap up the company’s distribution and growth strategy for Western European country in particular Italy. During that meeting, various difficulties facing the company such as new market penetration and new products to sales rationalization and branding programs were brought to light. However, the core of the issue facing Airwide International is not that revenue is plummeting or profit is at risk, which most companies might be having back in 2001, but the biggest issue for Airwide International is confronted with is internal to the foundation of the sales organization. Regional master distributors (RMD) and local dealers (LD) are not getting along. While the first “RMD” wants the company to eliminate the second “LD”, the opportunity that the second sees is expansion and more responsibilities because of their knowledge of the business and the trust the built for generations. Problem Statement: Regional master Distributors relentlessly pressured Airwide to eliminate Local Dealers so they can serve their local markets even though the dealers in certain areas had a share of their local markets approaching 20 percent compared to 12 to 16 percent of master distributors. Dealers on the other hand want to expand their territories beyond their defined geographical limits. Airwide International...
