Difference between air conditioning engineering machine and home machine

The difference between air conditioning engineering machine and home machine;

1. When we say sales unit construction machinery, we mean group consumption, such as installing dozens of machines in the whole building. In this case, the manufacturer has a special sales policy for publicity, such as a 30% discount on the supply price. The machine is exactly the same as the household machine sold in general shopping malls, but the price is different.

There are also some machines with special functional requirements, such as the computer room, which save the startup state after power failure and automatically recover after the call. This machine is specially made by the factory, and it is an engineering machine in the sense of the factory.

2, so from the product itself, there is no difference between air conditioning engineering machine and home machine, as long as the quantity is large, the manufacturer will give preferential treatment. Cheap engineers mainly reduce sales costs, but also have the function of advertising, so the price given by manufacturers will be low. Hang up at 32, 100. The price of more than one set can be 700-about 800 yuan.

3. The bulk purchase mentioned above is not very large. If it is large, it is estimated that manufacturers can customize it according to customers, but the quality will certainly not be bad. As for the types of air conditioners, we all adopt T3 climate, which is generally adopted in China, that is, the outdoor temperature of refrigeration is not higher than 42 degrees, and the outdoor temperature of heating is not lower than minus 5 degrees.

Development history

origin

Around 1700 BC, the Babylonians had invented an ancient air conditioning system, which used the wind pole installed on the roof to blow cold water into the room from the outside to make people feel cool indoors.

/kloc-in the 9th century, Michael Faraday, a British scientist and inventor, discovered that compressing and liquefying a certain gas could freeze the air. This phenomenon appeared when liquid ammonia evaporated, and his idea was still theoretical at that time.

1842 Florida doctor John Gorrie compressed a new building with central air conditioning. Alfred Wolff, an engineer in hoboken, New Jersey, helped design this brand-new air conditioning system and transferred this technology from textile mills to commercial buildings. He is regarded as one of the pioneers in reducing the temperature of the working environment.
