Air Conditioner 3D model - a device for maintaining optimum climatic conditions in buildings, vehicles and other equipment.
In its simplest form, the air conditioner is designed to regulate and maintain the desired air temperature in the room. Most commonly, air conditioners are used to reduce the indoor air temperature during the hot season and year-round in rooms where excessive heat is generated (computer centers, subway cars, aircraft stores, auditoriums, auditoriums, etc.) or a certain temperature is required. (food warehouses, operating). Air conditioners with heat pump function along with cooling allow to increase the air temperature in the cold season and can be used as a cooling and heating device. More sophisticated air conditioning systems are equipped with air purification mechanisms for polluting particles, fresh air inflow, air humidification, air enrichment with oxygen and other functions that increase air quality.
The modern concept of "air conditioning" as a designation of the device to maintain a given temperature in the room, there is a long time. It is interesting that for the first time the word conditioner was uttered out loud in 1815. It was then that the Frenchman Jeanne Shabannes received a British patent for the method of "air conditioning and temperature control in dwellings and other buildings." As a matter of fact, for the English language the verb to condition is quite standard and means including “improve something to the desired state”, in this case air to a state comfortable for a person in terms of temperature, humidity and other parameters; Thus, the conditioner according to the rules of word formation in the English language is simply that or the one who carries out such a conversion to a certain state, and not any neologism. Hence, the same conditioner for hair and linen, which are no longer appliances, but household chemicals.
Air conditioning was used in the powder cellars of military vessels. That is why Air Conditioner 3D model is a very popular among military game developers and 3d artists who use it for 3D printing.
However, the practical implementation of the idea had to wait long enough. Only in 1902, American engineer-inventor Willis Carrier (Willis Carrier) assembled an industrial refrigeration machine for the printing house of Brooklyn in New York. The most curious thing is that the first air conditioner was intended not to create a pleasant coolness for the workers, but to combat the humidity, which greatly impairs the print quality.
The first indoor air conditioner, released by General Electric back in 1929, can be considered the “fossil” ancestor of all modern split-systems and window units. Since ammonia was used as a coolant in this device, the vapors of which are unsafe for human health, the compressor and air conditioner condenser were brought to the street. That is, in essence, this device was the real split-system. However, since 1931, when the first freon, which is safe for the human body, was synthesized, the designers considered it a blessing to assemble all the components and assemblies of the air conditioner in one case. Thus, the first window conditioners appeared, the distant descendants of which are successfully operating even today.
For a long time, leadership in the field of the latest developments in ventilation and air conditioning belonged to American companies, however, in the late 50s - early 60s of the XX century, the initiative firmly passed to the Japanese. In the future, they determined the face of the modern climate industry.
In 1958, the Japanese company Daikin offered the first heat pump, thereby teaching air conditioners to serve not only cold but also heat into the room.
In 1961, an event occurred that largely predetermined the further development of household and semi-industrial air conditioning systems - this was the beginning of the mass production of split-systems by the Japanese company Toshiba. Toshiba first launched into production air conditioning, divided into two blocks and the popularity of this type of HVAC equipment began to grow. Due to the fact that the noisiest part of the air conditioner - the compressor has now been taken out onto the street, in rooms equipped with split systems, it has become much quieter than in rooms where windows are working. The noise level has been significantly reduced. The second advantage was the ability to place the internal unit of the split-system in any convenient place.
Today, there are many different types of internal devices: wall, ceiling, floor and recessed ceiling - cassette and duct. This is important not only in terms of design - various types of indoor units allow you to create an optimal distribution of cooled air in rooms of a certain shape and purpose.
In 1968, an air conditioner appeared on the market, in which several internal units worked with one external unit. So there were multisplit systems. Today they can include from two to nine.
