The campus has always been a place where many people are paralyzed. Taking a step forward, we feel not only beautiful scenery, but also the deep and wise atmosphere left by the former people. When you visit the campus, you will often see some campus sightseeing vehicles carrying some students, teachers, or visitors on the campus trails. So what are the advantages of the campus bus? One, convenient. Nowadays, many campus facilities are relatively complete and large. It takes more than 30 minutes to visit a complete campus. The existence of a campus sightseeing vehicle not only facilitates student access, but also makes it easier for visitors to view. Second, environmental protection and safety. Most of the campus tourist vehicles use electric sightseeing vehicles. In an era of such intense energy, the use of electric sightseeing vehicles not only saves energy, reduces costs, but does not emit exhaust gas. The noise is small, and it is suitable for campuses that study. However, it is. In addition, the safety of the campus bus is also higher than ordinary buses. It is precisely because of his use of battery power that the relative speed will be relatively gentle. Coupled with the low-profile design of the car body, the safety performance of the campus sightseeing vehicle is greatly increased. It is a safety measure for pedestrians and passengers on the road. Protection. Third, small but flexible but large capacity. Because of its small size, the campus tour bus can shuttle freely through the campus trails. Although its shape is very low, but its capacity is not small, a small campus sightseeing car generally has a lot of rows of seats, can carry dozens of people, can often see the campus tour car is full of return . Things are not big and people are good. The existence of campus sightseeing vehicles not only has many advantages, but it has already merged with the campus and has become a beautiful landscape in the school. It represents not only a means of transportation, but also a feature of the school. If you have the opportunity to visit the beautiful scenery of the campus and feel the atmosphere of the campus, you must take a ride on the campus tour bus. Combined Flow Closed Cooling Tower
Closed Cooling Tower is operated by circulating water or fluid, which is divided into two closed loops.
1. Circulation in the tower: the circulating water or fluid passes through the hot zone environment. After the water temperature rises, it enters the surface cooler in the tower, and the heat is sent to the environment outside the tower through the surface cooler and ventilation fan. The cooled circulating water or fluid is sent to the heat source by the water pump.
2. Circulation outside the tower: the spray water is sent to the spray system by the water tank through the water pipe. After spraying, the spray water first exchanges heat with the filler, so that the spray water can be cooled rapidly. At this time, the water contacts the surface of the surface cooler for heat exchange. Part of the hot steam is discharged through the ventilation fan, and the cooled spray water drops to the water tank for secondary circulation to form an external circulation for cooling.
