Is air conditioner have been a primary

Temperatures in the world has increased every year. Which proves that the statement is supported by the melting of icebergs at the north pole and south pole. Size becomes more and more narrow. Meanwhile, the longer the sea area becomes larger and larger. This all happened due to human activity itself. That's because the cutting of trees in wild forests, increasing factory pollution, and increased use of sustainable vehicles such as cars, motorcycles, planes, trains, ships, buses, bajaj, and others.
Therefore, the depletion of the atmosphere. Ultraviolet direct heat can penetrate into the earth. Our bodies feel so heat during the day. Following the development of technology and community needs, electronics manufacturers race to create a variety of AC.
Initially created a device called a fan. Then, together with advances in science and technology by the inventor to create an air conditioner (AC). AC has advanced technology so that its price too high price value, so that only AC purchased by those high-class economy. Facing the challenge of situations like this, electronics manufacturers to make a new alternative, called the cold air. air conditioning became the answer to market demand for air conditioning products with a value relatively cheaper prices. air conditioning working principle similar to the principle of the AC. The difference between the cold air with AC is to use cold water and ice cubes and freon as a mediator.

Along with the development time, the development of AC increased rapidly. Almost all electronics manufacturers vying to produce air conditioners on a large scale. With technological breakthroughs and new innovations such as low-watt AC, plasma cluster (anti-bacterial), vitamins, mosquito killer, inverter technology, anti-rust, and anti-odor room.
Each manufacturer develops different marketing strategies to make people interested to buy the AC. Among them is the advertising in various media, including electronic media, mass media and the internet. Ads constantly, making air-conditioning demand increases dramatically. Producers try to meet the market demand constantly.

Reparation AC

Before you call a air conditioning service repair man to check your air conditioner that's not cooling you may want to check some of these possible causes. First and most obvious is to be sure your system air filter is not restricted. In many cases this will cause your evaporator or indoor coil to freeze up. If the system has a fan v-belt make sure it is not cracked broke or slipping. If the evaporator coil is froze up you may notice condensate leaking in and around the furnace, air handler or window type A/C unit. Another more apparent sign would be actually seeing ice build up on the coil or refrigeration lines connecting the evaporator and condenser.

Discovery air conditioner

The beginning of the AC (air conditioning) have been commenced in the Roman era with a reservoir of water that flows in the lower wall of the house so that the room temperature, but then only certain people can build it because the cost is very expensive because it requires water and also buildings that do not normal. Only the kings and rich people are able to build it, only later in the year 1820 the British scientist named Michael Faraday Image to find new ways cool the air by using ammonia gas and in 1842 a doctor found a way of cooling the room hospital located in Apalachicola Florida Ameika States . Dr.Jhon Gorrie is found and this is a technological forerunner of the AC (air conditioner) but unfortunately before he was dead perfect in the year 1855. Willis Haviland Carrier Image an engineer from New York United refine discovery of Gorrie Dr.Jhon but AC is used instead for the benefit and enjoyment of others but for the purposes of printing and other industries. The use of air conditioning for new housing was developed in 1927 and first used in disbuah house Mineapolis, Minnesota. AC current is used in all sectors, not only industry but also has offices and housing with a variety of forms ranging from large to the same kecil.semuanya is still functioning to cool to room temperature so that people feel comfortable.

When summer comes, we are always familiar with that name is also a fan or AC (Air Conditioner). Therefore, the cool air generated by fans and air conditioning is needed to reduce the heat so painful sometimes. Because of that, thank John Gorrie who sparked the idea of AC.
Because, with the cool air conditioned, we do not have to feel the pain because of the heat which sometimes makes the body feel like sticky due to sweat. But, do you know if John creates an AC because it was inspired by concern for the sick?.

Once there, John really is a doctor berwarga the United States. The idea makes cooling engine starts from the number of patients suffering from malaria or other penyakin with symptoms of high fever. When it is hot air that makes the patient uncomfortable. So, the man born Charleston, South California, October 3, 1802 is rack my brain how to keep the patient's body temperature can go down .. After seeing the fan in front of him, he found the idea. He put chunks of ice in front of the fan, so that ice cold can be spread by wind from the fan.

Tercetus the idea, then John's going for it menyeriusi cooler (AC). Thus, in the year 1844, he graduated from medical and surgical science in the city of New York is designing and developing ice-making machine experiments. Creation engine is based on the laws of physics that heat always flows from a gas or liquid to gas hotter or colder fluid. The machine works by compressing gas (compress) to become hot, then gases are channeled to the coil-coil for reduced pressure (dekompres). As a result, the air became cold.

To develop the invention, in the year 1845, Gorrie decided to stop the practice as a doctor. Six years later, he had received a patent which is the first patent issued for an engine coolant. This was originally found in the engine cooling is now known as the Air Conditioner.

Indeed, the story of John is proving that a genuine concern will lead us to goodness. From just want to cool the room where the patient, John now has managed to "cool" the world with his AC

Finder AC


Info this time telling the inventor of AC that part quoted from a book written by Katie Hafner and Mathew Lyon in his book: "where wizards stay up late", and the Indonesian version of the Overdrive with the publisher Shira Satria Media. Happy listening!

We do not need to feel the pain because of the heat which sometimes makes the body feel sticky with sweat. But you know what? If John created the AC because it was inspired by concern for the sick?

John was a doctor from the United States who are not from the Black skin (Negro) as reported so far.
The idea makes cooling engine starts from the number of patients suffering from malaria or other diseases with symptoms of high fever.

When it is hot air that makes the patient uncomfortable, the man who was born Charleston, South California, this October 3, 1802, turned his mind how to keep the patient's body temperature can fall.
After seeing the fan in front of him he found the idea. John put chunks of ice in front of the fan. It turned out to produce cool and fresh air as in mountainous areas

In the process, he designed and developed experimental machine ice maker. Creation engine is based on the laws of physics that heat always flows from a gas or liquid to gas hotter or colder fluid.

The machine works by compressing gas (compress) to become hot, then gases are channeled to the coil-coil for reduced pressure (dekompres). As a result, the air became cold.

To develop the invention, in the year 1845, Gorrie decided to stop being a doctor. Six years later he successfully received the first patent issued for an engine coolant. This was originally found in engine cooling now known as Air conditioner.

It's the story of John is proving that a genuine concern will lead us to the kebaikann. From just want to cool the room where the patients. John now had "cool" the world with his AC.

Circulation AC

Finally, this day can only post after a few days busy with homework, after yesterday discussing the indoor circuit and the circulation of air conditioning units on the topic this time cycle air conditioner outdoor unit.


click here the diagram circuit AC
Component 1 compressor.

Compressor is the heart of his air conditioner cooling function to keep flowing through the system at a certain level of flow, and at a certain pressure., Takes refrigerant vapor into the low pressure side (besa pipe), and the refrigerant vapor into the compressor and then processed into a higher pressure to the high side of the circuit. The level of flow through the system will depend on the size of the compressor unit, and operating pressure will depend on the cooling evaporator is used and the desired temperature.

Component 2 condenser.

Red dot on the exhaust pipe represent refrigerant. Solid red color represents high pressure liquid coolant. Most air and cold air cooling system is designed so that the refrigerant will condense at a temperature of about 25-300C on the temperature of waste air out. Hot condenser means working with a good compressor, the condenser heat in waste by one-legged (condenser fan) condenser coil absorbs enough heat from the steam that causes it to condense. Here we can see the outdoor unit out of the water from the pipes, so do not worry if there is water menetes.Ini heat transfer (condensation) of steam flowing into the air is what makes the hot air blowing out of AC units.

At this stage (drier), high pressure coolant fluid will flow down the liquid line, through a dry filter designed to prevent contamination from flowing through the system, then this high-pressure refrigerant will enter the drier, and continues to flow into the capillary tube ( smallest pipe in the system AC) dn turned into a low pressure.

faucet 3 meter components.

Kran meters or tree pulve way there are 2 types of small and large sizes for AC ½ to 1 pk tree using way ¼ "and 3 / 8" referred to a tap-meter because there are valves inside the lid with the key "L", tree way This is the dividing point between high pressure and low pressure side of the system, and designed to maintain a certain level of air flow to the lower side of the system. and will flow to the indoor evaporator.
Conditiong air system will be designed so that the refrigerant evaporates in the evaporator at a temperature of about 400C, so it will be cold than hot air flowing over it.
This system is designed so that the heat in hot air flowing through the evaporator is absorbed by the indoor evaporator pipes.


4 Evaporator indoor components.

Circulation Air Conditioner

Inside the air conditioned room air conditioning units cirkulation for work, to maintain comfort, the room must always be closed, meaning that the windows and doors do not open except when in need, first read about the design of air.
From the picture above can be implemented in the air cycle air conditioning follows:

1.Udara conditioned AC, That is air that has been chilled, the decrease in humidity and feces in the exhale filter into the room as supply air. This air flow velocity will range in 500fpm for low speed (low speed), 720fpm to medium speed (medium speed) and 1200fpm for high speed (high speed)


2. In the room air conditioner supply air will mix with the air of the room, so that the temperature and humidity of the room will be reduced. Decrease in temperature and humidity will be in accordance with the temperature and humidity for the comfort range of 220 - 250celcis

3. AC supply air that mixes with air in the suction back room by the indoor air conditioner unit through a filter and then into the evaporator and the heat absorption occurs at the suction and then going with a blower (fan ac) as an air return (return water)

4. Return air (return air) from the room will be mixed with dust or other dirt in the air, will terutam physical dirt in the air filtered by the filter (filter) which is on the outside of the evaporator so that only air will be clear again when the AC supply you dirty air is not clear that the dust generated due to dirt or small particles of another's accumulating on the old filter kelama make a dirty evaporator do care ac max / 4 months to get clean air and cool in the room.

5. Return air filter that has been in the stools they will be flowing through the evaporator where the heat absorption. heat in the air will move into the evaporator when Naahh AC evaporatornya dirty how can it absorb the heat so air conditioning was not cool to get used AC take care care tips when evaporator clean air conditioner from dust dirt then the maximum absorption of heat and air will be cold soon, when the air back through the surface of the evaporator will condense (condensation) so that the water vapor content in air will be reduced, water or moisture on the surface of the evaporator will fall and the waste out of the room as a drain.

6. Air from the evaporator to absorb heat was on and the blower blow by into the room as supply air, the air in the next cycle repeated again and so on.


Of the six stages of the cycle air conditioned space always includes the stages:
- Air supply
- Air space
- The air return
- Air filter (filter)
- Evaporator
- Blower

Hopefully this article can be useful and to understand more about the air cycle air conditioning room.
