In 1900 there was very little people could do during a hot spell except grumble about the weather or -if they could afford it -go away to the mountains or the seashore. Today air conditioning has changed this. With air conditioning has changed this. With air conditioning you can be comfortable anywhere indoors on even the hottest, stickiest day of the year. You will almost certainly find air conditioning in the movie theaters you attend, in many of the stores where your family shops, and in the restaurants where you eat. It may even be in your own home.
What is air conditioning?
You know that air conditioning makes you feel cool. But air conditioning is more than just cooling. It means keeping the temperature and humidity (moisture content)

Carrier who built is often called "the father of air conditioning." Carrier built this machine for a printing plant in Brooklyn, New York, that had trouble printing in color. Paper stretches when the air is damp and shrinks when the air is dry. Since each color had to be printed separately, printing of different colors on the same sheet of paper did not line up accurately because the papers change size between printings. Carrier's machine kept the moisture level of the air constant by drawing the air over a row cold pipes that condensed excess moisture. This kept the paper at one size and also made the people in the plant feel cool. Carrier's invention marked the begin of scientific air conditioning.
Air conditioning was soon being used in many factories, such as plants that made ammunition during World War I. But people generally did nit know about this invention until 1920's, when hundreds of movie theaters, department stores, and restaurants had air conditioners installed. People often came into these places just to get relief from hot, muggy air

Otherwise people would have to turn their units off and on continually as the temperature become too cold or hot. A steady temperature-regulating device called thermostat. The thermostat is set at desired temperature. It then switches the cooling unit on and off as needed.
The air conditioning systems of the future may work by what is known as thermoelectric. A thermoelectric unit is very small and very quiet. It is made up of tiny "couples," each couple consisting of a pair of semiconductors and connected in parallel current. These couples produce cooling at one end and heating at other when direct flows through them. This is called Peatier effect. When the current is reversed, the cooling and heating effects also reverse. When a way is found to produce this tiny thermoelectric unit cheaply, they may cool and heat your whole house.

For this reason the necessity of an air conditioner has been virtually eliminated. This could save hundreds in electric bills!

To be free from temperature and humidity threat, appropriate air-conditioning units with appropriate capacity should be installed alongside system units (stallings & Brown, 2015). Sensors should be installed in the premises also to warn when the threshold is exceeded.
Most people depend on their air conditioners. It is the only way to stay cool when you are inside of your home or office and the temperatures are soaring into the 90s and beyond as it often does in Fort Meyers and other areas of south Florida. The thing is, most older air conditioning units are not able to keep up with the heat as well as most people want for them to. Also, many people are now having to deal with the R22 Freon phase out that is taking place and it is causing a lot of people to suffer in misery.
In the 1920s, also known as the Roaring Twenties, many new household appliances came out to American consumers. One of them was the electric powered washing machine that clean clothes in an efficient and easy way. This product, the Thor, was a drum like washer with a tub and a electric motor and was created by Alva J. Fisher in 1908 (Bellis). Also,a vacuum cleaner is an electric tool used to suction up dust and small objects on floors. This tool was created by Hubert Cecil Booth and David T. Kenney in 1901 by using air for the separation of dirt (Green). Another appliance, the electric refrigerator, is a tool that keeps your food and drinks cold and fresh. The refrigerator was invented by Fred W. Wolf in 1913 and was a icebox with a refrigeration unit connected to the top (Chapman). All of these appliances made the twenties roar because it made labor easier around the household.
Franklin's fireplace solved these problems by using a number of passages and vents so that the cold air was drawn in from outside the building, warmed in the air passages, and then blown into the room. He said "your whole room is equally warmed, so that the people need not crowd so close round the fire, but may sit near the window, and have the benefit of the light for reading, writing, and needlework. They may sit with comfort in any part of the room, which is a very considerable advantage in a large family, where there must often be two fires kept, because all cannot convenientl! y come at one" (Seeger 166). Several people considered the fireplace a luxury for the wealthy.
One of the other big concerns for northern cities was finding a way to keep the buildings warm in the winter. It was not possible to use fireplaces on the higher floors. The problem was solved in the 1870’s by the development of heating systems that circulated steam through radiators on the higher floors. These new
High outdoor temperatures are hard on cars, and operating the air conditioning adds to the stress on the cooling system, belts, hoses, and more. A properly operating air conditioner will not only provide for your comfort, but will cause less work and wear on the vehicle's systems.
Two years later, in 1941 in married the lovely Elizabeth Marsh Wise and we took care of my adopted sons. In 1949 my company and I announced that soon we would install air conditioners in the four most popular skyscrapers in New York. Finally, on October 7, 1950 in New York City, New York, the inevitable occurred I, Willis Haviland Carrier, the inventor of the first scientific air cooling system, died from a Heart Condition that I had been suffering from for quite some time.
As the summer months and warmer temperatures approach, businesses ranging from restaurants with outdoor seating to car washes and outdoor shopping malls are charged with making sure their customers remain cool and comfortable. Faced with this challenge, many business owners turn to advanced misting systems featuring outdoor misting to keep things cool. Misting options come in many shapes and forms, but a commercial misting system is best for keeping the outdoor option open to your business and its patrons all summer long.
During the hot summer months call us to provide AC service anytime that your system isn't running as it should. If you find that your air conditioner is running, yet the temperature isn't dropping as it should, you may need AC service. The best time to have us out to check on your system is before the temperature soars. Be ready
If you haven’t already, think about replacing your thermostat with a “smart” version. This type of thermostat will not only save you money on your monthly energy bills, it will also allow you far more flexibility on how you cool your home. A “smart” thermostat will allow you to cool only certain rooms if you choose and run your air condition during the hottest times of the day. You can also operate your thermostat from your phone giving you ultimate flexibility and control over your home’s cooling.
In the early 1930’s air conditioning was invented by Willis Carrier. It was not like the air conditioning we have today, back then the air conditioning systems were not aimed at human comfort, however they were designed to control the humidity. Another invention that many people use today is colored television. In 1940 CBS began experimenting with color field tests using films as early as August 28, and live cameras by November 12.
Incandescent bulbs' design causes them to output heat, which is what contributes to electricity costs. The heat generated will cause the air conditioner to kick on more in hot weather. LEDs will reduce cooling costs by not producing heat.
Thermoelectric cooling uses the Peltier effect to create a heat flux between the junctions of two different types of materials. A Peltier cooler, heater, or thermoelectric heat pump is a solid-state active heat pump which transfers heat from one side of the device to the other, with consumption of electrical energy, depending on the direction of the current. Such an instrument is also called a Peltier device, Peltier heat pump, solid state refrigerator, or thermoelectric cooler (TEC). It can be used either for heating or for cooling, although in practice the main application is cooling. It can also be used as a temperature controller that either heats or cools.
