Air-conditioning refers to the combined process of conditioning of air in a specific space. Such processes of air include providing heating or cooling, humidification or dehumidification, air cleaning or filtering, as well as the distribution of the conditioned air. In other words, air conditioning controls and maintains different parameters in the specific space such as temperature, humidity, cleanliness and pressure differential with surroundings. The purpose of air conditioning can be divided into to two categories. First is for comfort air conditioning which focuses on providing comfortable and healthy indoor environment to the occupants. The other one is for process air conditioning which focuses on controlling and maintaining predetermined …show more content…
The conditioned supply air is then distributed to the conditioned space through ducts, terminals, and diffusers. There are disadvantages in using chilled water air conditioning system such as extra electricity consumption for circulating pump of chilled water and lower system capacity due to some heat gain through transmission & friction. However, it is widely used for air-conditioning of large hotels, office buildings and malls due to its flexibility when it comes in selection, layout and operation (Ananthanarayan, P.N. 2013) especially that the central refrigeration plants and even the air-handling unit can be remotely installed from sensitive areas of the said buildings. Additionally, water flow makes it possible for the heating and cooling capacities to be modulated with accuracy (Wang, S.K. …show more content…
It can use to significantly help meeting the demand for heating or cooling efficiently and environmentally by correcting the mismatch between the supply and demand of energy. There are generally two types of TES systems which are sensible TES and latent TES. Potential application of sensible TES technologies, which uses rock or water, are mainly in residential buildings. The latent TES systems are primarily used in HVAC systems to minimize the energy consumption in industrial and commercial buildings by shifting on-peak demand thermal loads, usually at daytime, to off-peak conditions, usually at nighttime (Kalaiselvam, R. & Parameshwaran, R., 2014). TES systems applied in air conditioning systems are using either an ice storage or a chilled water storage. Phase-change material storage systems are also used but have limited applications in commercial buildings due to high discharge temperatures and high required storage tank volume (Wang, S.K.

In 1992, after the accomplishment of the Air Jordan VI and Michael Jordan 's first NBA Championship, Tinker Hatfield proceeded with his development in the Air Jordan line with the Air Jordan VII which was inspired by West African Tribal society and in part by the Nike Huarache basketball shoe line. The AJ VII had a more brilliant, more insignificant, and more lightweight design than past Air Jordans. Unlike the previous Air Jordans where the air bubble was visible, this was not the case with the AJ VII. The translucent outsole and prominent Nike logo (aside from on the insole) were also modified differently than previous AJ. Michael Jordan wore the Olympic-inspired version of the VII as he drove the "Dream Team" to a Gold Award at the 1992 summer games in Barcelona.
Klinenberg’s compelling use of word choice is displayed all throughout the passage. He says, “What’s indefensible is our habit of converting homes, offices and massive commercial outlets into igloos on summer days.” He uses the word “habit” to reveal to us how often we are prone to rely on air-conditioning to turn our buildings into “igloos”. The negative connotation of the word “habit” forces readers to acknowledge that air-conditioning use is a problem. He uses quotes like “turn down the dial on our own” and “wilt in searing temperatures” to put a certain image in the reader’s mind.
For people who struggle with sight, glasses are a general source of clarity. But, the second the glasses are removed life becomes an intimidating blur. However, the moment the thick layered comfort is removed and something new is brought into life, the fog clears. Much like the haze that follows the removal of glasses is the haze that dwells in the mind of an adolescent. Transitioning between childhood and adulthood is a mesh of fog and disconnection from comfort that will eventually clear with growth and maturity.
Before this invention, drivers had to manually load and unload ice to maintain the temperature inside their trucks. However, Jones's new system eliminated the need for manual loading ("Frederick McKinley Jones" Biography.com). According to the National Inventors Hall of Fame, his automatic refrigeration system maintained a consistent temperature inside the truck, ensuring the preservation of perishable goods ("Frederick McKinley Jones" National Inventors Hall of Fame). This invention not only improved the efficiency of the transportation but also reduced costs and increased the safety of the drivers. Jones's work in this field established him as a pioneer in refrigeration technology, leaving a big impact on the transportation
Ventilation of a person through various activities Camila Gonzalez. This lab was made with the aim of proof that making different activities can alternate the ventilation rate, also is to see the variation of work our respiration system makes. We can see the different things and situations that can affect the normal process of ventilation and respiration, like the weather and the clothes that were limitations for doing this experiment because first the weather was so hot, so the person get tired early and began to ventilate faster and second the clothes wasn't appropriate for making the activities, because they also make weight and makes that the person get more tired. We use more than one person to make a comparison of the ventilation
Self-discovery is driven by the willingness of individuals to make connections with places and people. This is evident in Tara June Winch 's novel "Swallow the Air" as the protagonist discoveries are seen through her connection with the people and her identity. Similarly, the same can be said for James Cameron 's film "Avatar" as Jake the protagonist discoveries is 'visualised through his connection with the land and how this affects his identity. In both of these texts, we can identify how both Tara June Winch and James Cameron interprets the concept of self-discovery in their text.
Waiting on every exhausting whim of an 18 year old preserved corpse sounds absurd and impossible, but for H.P. Lovecraft’s first person narrator in “Cool Air” it is a shocking reality. The strategic application of first person point of view keeps the reader on edge with a limited view. Any other point of view would reveal too much information on the pivotal Doctor Muñoz, and not allow access to the narrator's thoughts and emotions. First person point of view in H.P. Lovecraft’s “Cool Air” connects the reader to the emotions of the narrator and keeps critical plot information a mystery.
Background & History Hyatt Hotels Corporation is involved in the franchising, management, development and ownership of Hyatt-branded resorts, vacation & residential ownership properties, and hotels internationally.

3 MATERIALS AND METHODOLOGY 3.0 INTRODUCTION Energy analysis of buildings helps to simulate the amount of energy used in a building. It is very important as it helps to discover and ascertain new ways of conserving energy and ensuring energy efficiency of building components. Building developers, construction engineers are increasingly interested in creating more energy efficient reason, and for this purpose whole building energy simulation programs are being used to determine strategies that save energy and are cost effective. The most common way available to perform this building energy analysis is to implement building information modelling(BIM). Building Information Modelling(BIM) consists of a digital representation of physical and functional

Specify organisational standards of customer service So the customer segment of the Ritz-Carlton is a wealthy clientele who has very high expectations since they use to get upscale products because they are ready to pay more to have more. Therefore, the differentiation of the Ritz-Carlton is made on an efficient and effective customer service. As we know the needs are general but the wants are specific, so the companies have to make the difference so as to become the customer’s wants. For example, customers will need to book an hotel room but some customers will want to book an Ritz-Carlton hotel room.
Introduction. One of the crucial problems that world facing is energy use and energy efficiency is the main solution for this issue. As Juodis (2009) mentioned, term energy efficiency has two meaning, namely minimal consumption of energy and cost-effective energy use which is smallest amount of energy consumption to keep convenient hygiene conditions in a building. Energy efficient construction should be compulsory in Kazakhstan.
The Chrysler Building, New York, is one of the most admired Art Deco style skyscrapers in history. This essay will analyse the Chrysler Building contextually and evaluate the applicability of the theoretical features of the early Modern Movement, as described by Paul Greenhalgh, to it in an attempt to determine exactly what it is that makes the Chrysler Building the icon that it is today. Historical Background The Chrysler Building has a rich historical background from which it originates. The famous 77-story Art Deco skyscraper was constructed between the First World War (1914-18) and the Second World War (1939-45) in Manhattan, New York.
