History of appearance
By 1933, air-conditioners in the US had already become an integral part of the premises. In 1936, special air-cooling systems for vehicles were developed. For the first time, they were used in Baghdad-Damascus passenger trains. The first car in which the air conditioner was installed became Packard. However, the installation of such equipment cost a very expensive-car, on average, could be bought for $742, to install the air conditioner cost $274, that is a third of the price. It was also inconvenient that the system occupied half of the boot and there was not even a hint of automatic control. Such air-conditioners were not popular and soon ceased to be offered. In 1941, the air conditioning system offered another American manufacturer-Cadillac.
The Second World War stopped the development in this area. It was not until the end of the case that the case was resumed. In 1954, there was a revolution in the production of air conditioners. Nach-Kellovinator cars installed a general system of ventilation and heating. It included an air conditioner and a heater. The system was already much smaller and was under the hood. With these convenient and practical systems, the popularity of automotive air conditioners has grown. By the early 1990s, 55 per cent of the cargo in the United States and 90 per cent of passenger cars were air-conditioned. In the USSR, the air conditioners were first seen only on government cars. The first air conditioner was installed on the government's "ZIL-111-G". It was only in 1976 that the decree used air conditioners on combine harvests, trucks and career dump trucks.
The first car with air conditioning appeared in 1940. They became the American Packard
