Process Cooling Water
In a typical cooling water application, two process loops are used – a process water loop and a cooling water loop.
On the process water side, water is pumped to the equipment being cooled. The process water carries away heat generated from the equipment, allowing the equipment to maintain its efficiency and operation at controlled temperatures.
The hot process water is pumped to a heat exchanger, where it transfers the absorbed heat to the cooling water side. The cool process water is then pumped back to the process equipment to absorb more heat. The hot cooling water then returns to the cooling tower, where its absorbed heat is either released through evaporation or convective heat transfer to the atmosphere. The cooling water then returns to the heat exchanger to absorb more heat from the process side.
The performance of a cooling tower is in direct relation to the efficiency of the heat transfer process, and water quality within the tower.
