Air conditioner history

Today, most cars are equipped with an air conditioning system, and the existence of reasons such as lack of proper insulation in the car body, noise pollution, air pollution, etc. makes it practically impossible to imagine today's cars without an air conditioning system.

Air conditioning systems work on the principle that "liquids absorb heat when they turn into gases."

For example, alcohol feels cool when rubbed on the skin. This is because alcohol absorbs heat from its surroundings as it evaporates. It is quite evident that heat is necessary to convert liquids into gases. Heat is absorbed from the contact area with the liquid, thereby cooling it. This very simple principle is the basis of cooling systems, such as air conditioners and refrigerators.

The figure below shows the main components of a car cooler.

R-12 gas is used in old cars and R-134A and R-1234YF gases are used for the air conditioning systems of most modern cars because it evaporates and liquefies easily and is chemically stable and does not degrade.

History of car air conditioner

1921

The first air conditioner in the car cabin was the use of an electric fan, which of course did not work to reduce the temperature.

1930

The first device to reduce the temperature through water evaporation was installed in the car. For this purpose, a device similar to a vacuum cleaner was used next to the window on the passenger side, with an efficiency similar to today's water coolers, which were certainly useless in areas with high humidity.

1939

Packard becomes the first car manufacturer to offer air conditioning as an option. This cooling system was located in the trunk, and to turn the system on or off, the drive belt had to be manually installed or removed from the compressor.

The very high cost (for that time) which was around $274 and the start of World War II made this system unsustainable and quickly removed.

1953

A few years after the end of the war, A/C finally returned to the automotive industry. Several manufacturers offered air conditioning as an option, all of which were mounted in the trunk and were identical to the 1939 Packard model.

1954

The era of new car cooler systems

Pontiac and Nash become the two companies that put the air conditioning system in the front of their cars instead of the trunk. The Nash system put the heater and cooler in one dashboard package, setting the standard that most cars have followed ever since.

1964

Cadillac introduces Comfort Control. For the first time, drivers can set a desired temperature and the system will automatically adjust the A/C (cooler and heater) to maintain the interior at that temperature.

1987

Due to concerns about ozone depletion, the Montreal Protocol has been signed and provides a plan to phase out the R-12 refrigerant used in most A/C systems.
