The development history of the automotive air conditioning I

As we all know, as early as 1886, Karl-Benz in Germany produced the world's first three-wheeled car. Although there have been endless inventions of cars since then, the advent of car air conditioners was nearly half later than the development of cars. Centuries.

Since the car did not have a sealed body at the beginning, how to control the “inside” temperature of the car does not seem to be something that engineers should worry about: in winter, people only need to wear a little heavier; in summer, the speed of more than 20 kilometers per hour can also bring people a little bit. Coolness. When the car began to install the closed body, people who could not stand the sultry heat still considered how to reduce the temperature through ventilation-such as digging a few holes in the car floor.

In 1927, the first automobile air-conditioning device appeared in the New York market of the United States, which caused a sensation among automobile manufacturers in various countries. In fact, this kind of device can only be called a "heater", it just adds heat in the car compartment, but in the cold season in Europe, it can play a certain role in keeping warm, it can be regarded as the pioneer of car air conditioning!

The single heating air conditioner first appeared in the United States, using automobile cooling water for heating, and by 1927 it developed into a relatively complete heating system with heaters, fans and air filters. However, this heating system did not appear in Europe until 1948, and Japan did not start using heaters for heating until 1954.

What we usually call car air conditioners did not actually appear until 1938. American Pald invented car air conditioners based on the principle of "air-conditioning" in refrigerators. The Lincoln V12 was fortunate to be the first car to install air-conditioning. In 1940, the American Packard Company used mechanical refrigeration for automotive air conditioners for the first time, which opened up a development path for the world automotive air conditioner market. However, this type of air conditioner was bulky and inconvenient to control. By 1941, manufacturers no longer provided such installations.

Just as the car air conditioner was preparing to show its talents, World War II suddenly broke out, causing the development of car air conditioners to be interrupted for a while. After the end of World War II, the practical and popularization of automobile air conditioners began to gradually resume development.

Soon after the war, Cadillac introduced a "new" air-conditioning device, which was mainly manifested in the air-conditioning control system. However, this kind of control system is located at the rear of the car, which seems incredible today: if there are passengers behind the car, it’s okay to say, turn around to turn on and off the air conditioner, and if there are no passengers in the rear, the driver will I had to get out of the car and turn on the air conditioner. It was too much trouble.

As a result, some smart American car manufacturers began to spend a lot of money to research car air conditioners. By 1953, refrigeration and air conditioners could be used in ordinary cars, and technological advancement made it possible to mass produce car air conditioners.
