When was the chiller, or air conditioner, invented

Around 1000 B.C., the Persians had invented an ancient air conditioning system, using a wind pole installed on the roof to blow the natural wind from the outside through the cool water and into the room, making the people inside feel cool.

In the 19th century, Michael Faraday, a British scientist and inventor, discovered that compressing and liquefiing a gas could freeze air, and when the phenomenon of liquefied ammonia evaporated, his idea was still theorized.

In 1842, the new building inaugurated by Florida physician John Gorrie was air-conditioned. Alfred Wolff, an engineer from Hoboken, New Jersey, who helped design the new air-conditioning system and moved the technology from a textile mill to a commercial building, is considered one of the pioneers in making the work environment cooler.

In late 1902, the first modern, electrically propelled air conditioning system was invented by Willis Carrier (1876-1950). The difference between the design and the wolff's design is that it not only controls the temperature, but also controls the humidity of the air to improve the quality of the production process in a printing house in Bucklin, New York. This technology provides a low heat and humidity environment, resulting in more accurate paper area and ink arrangement.

Later, Carrier's technology began to be used in the workplace to improve productivity, and Carrier Engineering was established in 1915 to cope with the surge in demand. With the gradual development, air conditioning began to be used to improve the comfort of the home and the car. Sales of residential air conditioning systems didn't really take off until the 1950s.

Built in 1906 in Belfast, Northern Ireland, the Royal Victoria Hospital is of special architectural significance and is known as the world's first air-conditioned building.

Stuart W., Charlotte, North Carolina, USA, 1906Cramer is looking for ways to increase air humidity in its southern textile mills. Cramer named the technology air conditioning and used it in a patent application the same year as an alternative to water conditioning.

Water conditioning was a well-known procedure at the time that made the production of textiles easier. He combined water vapour with ventilation systems to "regulate" and transform the air in the factory, controlling the humidity of the air in the textile mill, which is of utmost importance. Willis Carrier used this name and incorporated it into the name of the company he founded in 1907:

American Gallia Air Conditioning Company" (now Carrier Corporation).

In 1915, Carlil founded a company that remains one of the largest air-conditioning companies in the world. But in the 20 years since the invention of air conditioning, it has always been machines, not people, that have been enjoyed. Until 1924, a shopping mall in Detroit, often because of the hot weather and many people fainted, and first installed three ** air conditioners, which was a great success, the cool environment made people's consumption intentions greatly increased, since then, air conditioning has become a powerful tool for businesses to attract customers, and the era of air conditioning for people has officially come.

On July 17, 1902, at a printing house in Brooklyn, New York, USA, the first real air conditioner was put into operation.

Carrier, an American, invented the world's first air conditioner in 1902, and the world's first split air conditioner was invented by Toshiba in 1961.

In 1877, a German scientist invented the first refrigerator.

Refrigeration technology has a history of more than 100 years, and the early Japanese Mitsubishi company has been making air conditioners in refrigeration and so on.

The exact date of invention of the air conditioner is 1902.

At the time it was called Air Conditioning System, by Willis. Carrier invented that the structure, function, and so on are different from modern air conditioners. Residential air conditioning began to gradually become popular in 1950, but in 1986, when it was used on a large scale in China, brands such as Chunlan and Huabao began to be vigorously promoted, and entered thousands of households, and now many air conditioning brands have appeared.

Air conditioning

Air conditioner refers to the equipment that uses artificial means to regulate and control the temperature, humidity, flow rate and other parameters of the ambient air in the building or structure. Air conditioning generally includes cold source heat source equipment, cold and hot medium transmission and distribution system, terminal device and other major parts and other auxiliary equipment. It mainly includes refrigeration hosts, pumps, fans and piping systems.

The terminal device is responsible for using the cold and heat from the transmission and distribution to specifically treat the air state and make the air parameters of the target environment meet certain requirements. Air conditioning is an indispensable part of modern life, air conditioning provides people with coolness and warmth, but at the same time, air conditioning is always on is also easy to cause diseases, such as "air conditioning disease", etc., need to be used with caution.

For a long time, people began to collect and store natural ice in the winter, and put it in ice cellars, which was used for food refrigeration and heatstroke prevention in the summer, which was the refrigeration technology of people in the earliest times. With the development of refrigeration technology, the rear refrigerator appeared.

Do you know who invented the world's first refrigerator? What happened to its development? Today, I will briefly tell you about the history of the invention of the refrigerator.

In 1834, Jacobi Perkins of England successfully trial-produced a refrigerator that could work continuously by rotating ether as the working medium. It was the world's first chiller. After this, scientists.

did not abandon the development and modification of the refrigerator, but continued to improve and refine the refrigerator, in 1844, the United States JGori trial-produced a refrigerator that uses air as the working fluid, and this refrigerator is used to make ice and help cool the air in the hospital. The refrigerator developed this time has been much improved compared with the previous smart machine.

Then, from 1872 to 1874, Bell and Linde invented the ammonia compressor in the United States and Germany respectively, and made the ammonia vapor compression refrigerator, which was the beginning of the modern refrigerator.

Around 1960, the Carré brothers of France have successfully developed refrigerators with sulfuric acid and water as the main working fluids. Absorption chillers and ammonia.

Absorption chillers. After this, there were steam jet chillers, freon refrigerants.

compression chillers, etc.

The above is the history of the invention of the refrigerator, but the scientists did not stop there, they still continue to develop and transform, until now. The discovery of refrigerators has given us a better place to store our food. The research and development of refrigerants also laid the foundation for the refrigerators we use now.

Because after its invention, scientists continued to research and modify it, so that we have the refrigerator we use now. That's the impact of chillers.

Jacobi. Perkins, this person invented the refrigerator through the ether reed, in 1844, the Americans used air to improve the refrigerator, with the progress of the times, some people continue to change the refrigerant, so that the collapse of the refrigerator into many syndicate factories, into the lives of many people.

On July 17, 1902, the Sackt Williams Printing and Publishing Company installed this equipment of its own design, and the results were good, and the world's first air conditioning system (referred to as air conditioning) was born.

Uses of air conditioners:

1. Cool down. In the design and manufacture of air conditioners, it is generally allowed to control the temperature between 16 and 32. If the temperature is set too low, on the one hand, it will increase unnecessary power consumption, and on the other hand, when the temperature difference between indoor and outdoor is too large, people can not quickly adapt to the temperature change in and out of the room, and they are prone to colds.

2. Dehumidification. Air conditioners are accompanied by dehumidification during the refrigeration process. The relative humidity of the environment where people feel comfortable should be around 40-60%, and when the relative humidity is too high above 90%, even if the temperature is within the comfortable range, the person still feels bad.

3. Heat up. Both heat pump and electric air conditioners have a heating function. The heating capacity gradually decreases with the decrease of the outdoor ambient temperature, and if the temperature is -5, it can hardly meet the heating requirements.

4. Purify the air.

The air contains a certain amount of harmful gases such as NH3, SO2, etc., as well as various odors such as sweat odor, body odor and bathroom odor.

The air conditioner was invented in 1902.

At the time it was called Air Conditioning System, by Willis. Carrier invented that the structure, function, and so on are different from modern air conditioners. Residential air conditioning began to gradually become popular in 1950, but in 1986, when it was used on a large scale in China, brands such as Chunlan and Huadan Brother Bao began to be vigorously promoted, and entered thousands of households, and now many air conditioning brands have appeared.

The principle of air conditioning seems simple now, but at the time it was of epoch-making significance. Air conditioners are widely used in China, and domestic brands such as Gree, Haier, Midea, Chunlan, Oaks, etc. are very famous in the world.

Air-conditioning maintenance during special periods

During the mild temperature seasons from March to May and September to November, people generally leave the air conditioner in a non-working state. In the season when the air conditioner is not in use, the first thing to do is to turn off the power of the air conditioner, but it is best to keep the amount of use once a month to prevent the condensation of the lubricating oil in the machine due to long-term non-use. At the same time, in order to ensure the long-term high-speed operation of the air conditioner and the extension of the use mission, it is necessary to pay attention to the proper maintenance of the air conditioner when suspending the use and starting to use the air conditioner.

1. After the end of the use season. Before the air conditioner is suspended, the air conditioner can be set to the air supply state on a sunny day, and the air conditioner can be turned on for about half a day to make the air conditioner completely dry; At the same time, the dust filter, indoor unit, and outdoor unit should also be cleaned.

2. Before the start of the use season. Check that there are no obstacles in the air inlet and outlet of the indoor and outdoor units, so as not to reduce the working efficiency of the air conditioner; Install a dust filter to avoid damage to the machine or cause failure due to dust entering the machine; Wash the remote control with a dry cloth, not a glass cleaner or a cloth containing chemicals, and put two new batteries of the same model in after cleaning.

1. The world's first air conditioner was born in the United States, in 1902, and was a Carrier air conditioner.

2. Inventor Willis Carrier is known as the "father of air conditioning" because of his great contribution to the air conditioning industry.

3. Air conditioner is an air conditioner, which regulates temperature and humidity, and hang-on air conditioner is a unit used to deal with air temperature changes in a space area (generally closed). Its function is to adjust the parameters such as temperature, humidity, cleanliness and air flow rate of the air in the room (or enclosed space or area) to meet the requirements of human comfort or process.

4. Air conditioners are divided into single cold air conditioners and cold and warm air conditioners, the working principle is the same, and the refrigerant generally used in air conditioners is freon. The characteristic of Freon is that when it changes from a gaseous state to a liquid state, a large amount of heat is released.

When the liquid state changes from a gaseous state, it absorbs a large amount of heat. Air conditioners are designed based on this principle.

5. In the design and manufacture of air conditioners, it is generally allowed to control the temperature between 16 and 32. If the temperature is set too low, on the one hand, it will increase unnecessary power consumption, and on the other hand, when the temperature difference between indoor and outdoor is too large, people can quickly adapt to the temperature change when they enter and exit the room, and they are prone to colds.

6. The air conditioner is accompanied by dehumidification during the refrigeration process. The relative humidity of the environment where people feel comfortable should be around 40 to 60%, and when the relative humidity is too large, even if the temperature is within the comfort range, the feeling is still not good.
