__MAJOR ENERGY SUPPLIES (ELECTRICITY DEMAND)__

=__Air Conditioning__= The term **air conditioning** most commonly refers to the cooling and dehumidification of indoor air for thermal comfort. The term can refer to any form of cooling, heating, ventilation or disinfection that modifies the condition of air. Air Conditioning is an appliance, system, or mechanism designed to stabilise the air temperature and humidity within an area (used for soiling as well as heating depending on the air properties at a given time.) //__**Cooling**__-// Cooling is the transfer of thermal energy via thermal radiation, heat conduction or convection. //__**Heating**__//- Provides warmth to the whole interior of a building. //__**Ventilation**__//- Ventilation is movement of air into and outside the body. //__**Disinfection**__//- are antimicrobial agents that are applied to non-living objects to destroy microorganisms.



The concept of air conditioning is known to have been applied in Ancient Rome, where aqueduct water was circulated through the walls of certain houses to cool them. Similar techniques in medieval Persia involved the use of cisterns and wind towers to cool buildings during the hot season. Modern air conditioning emerged from advances in chemistry during the 19th century, and the first large-scale electrical air conditioning was invented and used in 1902 by **//__Willis Haviland Carrier.__//**

//__What is the problem at hand?__//
The problem at hand is that air conditioning is an electricity device which means that we're using alot of electricity which results in the increase of bills. Another reason is because we people don't take things seriously and especially at summer times; many people just take the use of air conditioning for granted, not knowing how expensive it can be and how much energy it takes up. Also air conditioning can promote the growth and spread of microorganisms and cause illness. If an air conditioner is more than 10-15 years old then it won't work sufficiently or generate anymore so people might have to get another one.

//__Currently doing and not doing to solve the problem?__//
What people today are currently doing to solve the problem is creating a cooling center and a system such as the thermodynamic system that is easily use to cool the boundary of a room than just one area of a room; preventing the more energy that is used. Other things that people are currently doing to solve the problem is by creating and buying portable air conditioners that can be taken with you in any part of the room. On top of that people also contains ceilling fans that used less energy and electricity than air conditioning.

//__How it works?__//
An air conditioner is basically a refrigerator without the insulated box. It uses the evaporation of a refrigerant, like Freon, to provide cooling. The mechanics of the Freon evaporation cycle are the same in a refrigerator as in an air conditioner.
 * //__Evaporation__//**- It's the process by which particles escape from the surface of a nonboiling liquid and center the gas state.


 * 1) The compressor compresses cool //Freon gas//, causing it to become //hot, high-pressure// Freon gas (red in the diagram above).
 * 2) This hot gas runs through a set of coils so it can dissipate(disperse) its heat, and it condenses into a //liquid.//
 * 3) The Freon liquid runs through an expansion valve, and in the process it evaporates to become //cold, low-pressure// Freon gas (light blue in the diagram above).
 * 4) This cold gas runs through a set of coils that allow the gas to absorb heat and cool down the air inside the building.



There are many different types of Air Conditioning such as Split-system AC unit and Chilled-water and Cooling-tower AC Units.

__//The amount of CO2(Carbon Dioxide) it produces?//__
The amount carbon dioxide that air conditioning produces is about 1,300 times the amount it would leak or evaporate.

__//The amount of water Air Conditioning generates?//__
In some cases, such as cooling water it generates to about 250 tons of water. Every 8 hours of run time, a timer causes a purge pump to pump all water from the bottom of the unit (approximately 5-8 gallons). The float valve then causes more water to flow until a level of about 3.5 inches is restored.


 * Air Conditioning takes up some of the world's supply for it uses alot of electricity especially during the summer where it produces alot water. It also generates alot of energy through water system.

Critics may discuss the pros and cons about air conditioning and how it uses too much electricity or wasting too much energy.

Air Conditioning can solve many problems by helping the elderly ones when it gets too hot in the summer.

If I were to change how air conditioning used, I would make and air conditioning that doesn't generate alot of energy and electricity; also doesn't generate alot of water and carbon dioxide. I would try to create an air conditioning that has solar panels on every angles and sides that can rediate from sunlight and generate from there; doing all the work.**

 * < “ || With every change of volume (to the working body) a certain amount work must be done by the gas or upon it, since by its expansion it overcomes an external pressure, and since its compression can be brought about only by an exertion of external pressure. To this excess of work done by the gas or upon it there must correspond, by our principle, a proportional excess of heat consumed or produced, and the gas cannot give up to the //surrounding medium// the same amount of heat as it receives. ||> ” ||


 * “The skylines lit up at dead of night, the air-conditioning system cooling empty hotels in the desert, and artificial light in the middle of the day all have something both demented and admirable about them: the mindless luxury of a rich civilization" ||
