Characteristics Of Crossflow, Counterflow Cooling Tower Type
Nov 14, 2016

First, the type of cooling tower features

Cooling tower is the set of aerodynamics, thermodynamics, fluid science, chemistry, biochemistry, materials science, static and dynamic structural mechanics, processing technologies, and other disciplines for the integrated products. Water as a function of multiple variables, cooling is multifactorial, with many more variables effect process. Cooling tower water and air flow conditions, pros, and cons of different types of cooling tower, cooling tower industry is vexed at the academic issues, the argument forcefully promoted the development of technology of cooling towers, their weaknesses in the argument, the cooling tower technology continues to improve, to save energy, improve efficiency, reduce the investment goals such as continuous technical progress. Cooling tower thermal performance, low noise, low power consumption, bleach water is the key to measuring the quality of cooling towers, users and designers in selection of cooling towers over most concentrate on focus in the comparison.


And counter flow Tower:

1, water filling in the Tower, water from top to bottom, the air from bottom, opposite the two cooling towers.

2, counterflow cooling tower thermal performance, three cooling section:

① water distributor to fill this space, this stretch of the water is higher, so you can apply heat to the air.

II filling water and air heat exchange section.

③ filler paragraph to catchment space for water, water is cooled in this paragraph called "efficiency". North China water temperature can drop 1-2. To sum up, counterflow tower than the cross Tower in the same case, small packing volume 20%, countercurrent heat exchange process is reasonably high cooling efficiency of the tower.

3, the water distribution system is not easy to plug, fillers to keep clean is not easy to aging, moisture reflow is small, freezing ice more easily. Many designs can be combined, to the desired water temperature in winter can merge a single run or all closed fan.

4, easy installation and maintenance, low cost of construction, commonly used in air conditioning and industrial cooling cycle of large and medium water.


Second, cross Tower:

L, the water filling in the Tower, water from top to bottom, air Tower level flow direction is perpendicular to both a cooling tower in the tower. Often used in strict with noise in residential areas, is a use more air conditioning cooling tower. Benefits: energy-saving, low water pressure, the wind resistance is small, low speed motor configuration, without dripping noise and wind noise, filling and easy maintenance of the water distribution system.

2, with architectural shapes free to build a base more than one place, depending on the water temperature you want starts one or more cooling towers respectively.

3, should pay attention to is: framework to 40% heat exchanger requires much more volume of filler, filler easy to aging, water holes to plug, bad freeze-proof, humidity return. Advantages of crossflow towers is the shortcomings of counter-flow Tower.
