Chinese literal translation is air conditioning. Let's learn about the development history of air conditioning.
as early as 1756, William Cullen, a British chemist, invented the first artificial refrigeration technology in the world by using the principle of ether evaporation refrigeration.
But in 184, American doctor John Gori invented the world's first ice maker by using compression technology. At the same time, people in hospitals in Florida, USA, enjoyed the cool wind in hot summer for the first time.
Then in the 195s, refrigeration technology was widely used in all walks of life, such as food freezing, beer brewing and cold storage. However, while people use refrigeration technology in all walks of life, no one has invented air conditioning, because the refrigeration technology of air conditioning is slightly complicated.
But in 192, a young American engineer invented the world's first air conditioner, but the original intention of the invention was to solve the temperature and humidity changes of instrument parts. Later, with the demand of equipment and technology, the commercialization of air conditioners began to develop rapidly.
I am talking about cold and warm feng shui. Let me answer why air conditioning is called air conditioning, not temperature adjustment. First of all, we have to understand that the function of air conditioning is "air conditioning system", which is called "air temperature regulator" for short, so it is called air conditioning, not temperature adjustment for short.
emptiness applies to people and emptiness applies to things.
