Following points can help you to analyze the performance of cooling towers.
- Check the difference between the water inlet and outlet temperature.
- Measure the difference between the outlet cold water temperature and ambient wet bulb temperature.
- Check the ratio of range between cooling water inlet temperature and ambient wet bulb temperature.
- Measure the cooling capacity in KCal/hr or TR, given as product of mass flow rate of water, specific heat and temperature difference.
- Measure the rate of evaporation loss and cycle of concentration.
- Check the blow down losses which depends upon the cycle of concentration and evaporation losses.
