For the first time, the motorcycle was made by German engineers in 1885. He looked very primitive. An engine was installed in a wooden frame. The wheels, like the frame, were wooden. In our country, the production of motorcycles began in the 50s of the last century. And before the beginning of the 90s, motorcycles were very popular, since their cost is much less than that of cars. In rural areas, residents preferred motorcycles with stroller. Which gave them the opportunity to transport certain goods. In the early 90s, in our country, the growth of the automotive industry begins. Accordingly, the demand for motorcycles began to fall and their production has significantly reduced. Chinese manufacturers took advantage of this, increasing the production of their motorcycles. Fixing emphasis on the manufacture of motorcycles of the “Scooter” class.In Europe, the production of motorcycles is low. Only a few brands are produced. In the USA, the most popular brand of motorcycles, over the twentieth century, was Harley-Devidson. Currently, Motoroller class motorcycles are most in demand. Especially in cities with a population of more than a million inhabitants and countries with a large population (such as India, China). Motorollers help quickly overcome traffic jams, which is typical for many cities in the world. Motorcycles can be divided into several classes. For example: sports motorcycle, classic motorcycle, cruise, enduro, scooter. In each class of motorcycles, there are different model rows. At factories producing motorcycles, the question is acutely what industrial air conditioners are better to install to improve air ventilation. After studying the functions and technical characteristics of different types of industrial air conditioners, it is recommended to install central air conditioners. They can simultaneously perform several functions. Such as ventilation systems, air conditioning, humidifier and air purifier. The air processed by the central air conditioner through the air ducts system is distributed through the premises. The central air conditioning device is autonomous, therefore, whatever it functions, it needs an external source of the cold cold from the external compressor-condenser unit, as well as hot water from the boiler or from the central heating system.
