Products Description
The dry-wet cooler is used as a form of tubular indirect evaporative cooler. dry-wet cooler working principle: 1 secondary side of the hot water flow through the dry-wet cooler coil, divided into four stages of heat transfer:
a. The heat of the hot solution through convective heat transfer to the inner surface of the dry-wet cooler coil. b, through the tube wall heat transfer to the outer surface of the dry-wet cooler coil; c, from the outer surface of the dry-wet cooler coil to the flow of heat to the water film outside the tube, from the water film through the water film, from the water film to the water film;
b. Through the pipe wall heat transfer to the outer surface of the dry-wet cooler coil;
c. By the dry-wet cooler coil outer surface of the flow of heat transfer to the pipe outside the flow of the water film, from the water film from the evaporation and convective heat transfer to the air, the cycle is not their own.
Air circulation: The fan will dry-wet cooler outside the unsaturated air into the dry-wet cooler tower, the airflow through the coil, heat dissipation material and the secondary side of the spray water for latent and sensible heat exchange to absorb heat, and then through the dry-wet cooler of the water baffle air-water separation, and will be close to the saturation of the wet air discharged from the dry-wet cooler tower. The wet air will be discharged out of the dry-wet cooler tower.
Through the above circulation and heat exchange, the cooling tower cools the secondary side heat-carrying solution to the required temperature to be sent back to the system to maintain its normal operation.
The core advantage of dry-wet cooler: flexible regulation, intelligent control system dynamically adjusts the operation mode according to temperature, humidity and load to optimise energy efficiency.
