What is the function of an evaporative condenser? and comparison of advantages and disadvantages.
Mainly, the heat exchange form is divided into counter-current type and cocurrent type, and the upstream air inlet is all in the lower inlet to absorb air, and the heat exchange area is usually larger than the downstream one, also known as the total evaporation type.
The cocurrent type is a suction wind at the upper and lower sides of the inlet.
The heat exchange tube is more dense, and it forms the slam of spray water, which was first developed by the water cooling system.
The equipment also contains the filling of cooling water, which is basically a one-piece assembly of shell tube condenser and circulating water pump and cooling water tower.
Relatively speaking, the fully evaporative condenser is also a countercurrent type to save energy and electricity.
The cold evaporative condenser is available, which is improved on the basis of completely evaporative type, so that the refrigerant is first entered into the air-cooled heat transfer section.
Then goes into the spray evaporation section, the temperature of the spray will be reduced by a lot, which can reach 60 degrees, which can effectively reduce the evaporation and scaling of high temperature. It's a scientific improvement.
In addition, according to the different types of heat exchange tubes, there are many kinds of heat exchangers.
Stainless steel tube (corrosive gas), fertilizer tube (high pressure),Carbon steel hot dip zinc tube (ordinary), aluminum alloy tube (better heat exchange effect), copper tube (mainly used in water cooling)
The tube is divided into round tubes and oval tubes, etc. Some say that the elliptical tube can reduce the dry point, but the effect is not great.
