Cross-flow closed cooling tower

Cross-flow closed cooling tower, named by the direction of spray water and hot air horizontally, spray water flows downward from the top, the wind enters horizontally from the side, swept through the middle of the heat exchanger coil, and cross heat exchange with the falling spray water to reduce the temperature of the spray water. It is mainly composed of heat exchanger coil, shower water system, air extraction system and frame shell.

Overview of crossflow

It is mainly composed of heat exchanger coil, shower water system, air extraction system and frame shell.

working process

► Spray pump from the tank pumping water, pumped to the upper part of the heat exchanger coil, through the nozzle into an umbrella spray, continuous and uniform coverage on the outer surface of the pipe, forming a thin film of water, which part of the water to absorb the high temperature refrigerant in the pipe heat energy, converted into latent heat of vaporization, evaporation into a gaseous state, the refrigerant inside the pipe cooling cooled down or condensed into a liquid, the non-evaporated spray water, back down to the spray water tank;

Ð ► Extraction system, tower top fan for suction type, from the tower to discharge outward, the tower outside the cold dry air from the side into the heat exchanger coil, will have evaporated water vapor away, the air humidity and temperature increase, by the 2 heat exchanger coil in the middle of the fan pumped out of the tower.

► Inside the spray water tank, a float valve is set up to ensure that when the water level is low, the supply is automatically replenished to ensure a certain water level in the tank;

Operating Principle

► Internal Circulating Water System:The cooled circulating water inside the coil flows out from the tower body, and is sent to the heat source (cooled equipment) by the system circulating water pump, and the circulating water which is warmed up by heat exchange enters the coil again for cooling.

► Outer circulating water system: the outer spray water through the coil and filler contact heat transfer to achieve the purpose of cooling the circulating water inside the coil, fall into the lower tank, by the spray pump to the spray water tank again circulation

► The cooled water inside the coil exchanges heat and quality with the spray water and air outside the coil, which avoids the water pollution caused by the direct contact between the cooled water and the air . As the spray water is pre-cooled by PVC packing, its heat exchange effect is more obvious.
