1. BTC-S Series Closed Circuit Cooling Tower
The cooling wate is pumped to the nozzle above the condensing coil and sprayed evenly on the outer surface of the coil, forming a very thin water film. After the axial fan induced air, air from the top of the coil and the side of the fills fo into the equipment inside promote to lower water evaporation temperature and water film evaporation, strengthen the heat release of the coil. The high-temperature wate enters from the upper of coils, and flows out from the lower of coils after cooled by the outside water.
A small portion of the water is evaporated which removes the heat. The warm moist air is drawn sidewise also by the fan and is discharged to the atmosphere. The remaining water is cooled again by passing the PVC fills, then falls to the sump at the bottom of the unit where it is recirculated by the pump up through the water distribution system and back down over the coils.
2. BTC-N Series Closed Circuit Cooling Tower
The cooling water is pumped to the nozzle above the coil and sprayed evenly on the outer surface of the condensing coil, forming a very thin water film. After the axial fan induced air, air from the top of the coil and the side of the fills go into the equipment inside. It enhanced air flow and the formation of negative pressure in the case, promote to lower water evaporation temperature and water film evaporation, strengthen the heat release of the coil. The high-temperature water enters from the upper of coils, and flows out form the lower of coils after cooled by the outside water.
The water is evaporated which removes the heat. Parts of it become the moist air is drawn also by the fan and is discharged to the atmosphere. The remaining water falls to the sump at the bottom of the unit where it si recirculated by the pump up through the water distribution system and back down over the coils.
