| 요약2 | The chiller efficiency is an important factor for improving the efficiency of the central chilled water system. A low-condenser water temperature is required for the low cooling tower leaving water temperature, which affects the chiller efficiency. Various studies have been conducted to produce low-condenser water temperature, but an additional review is needed on a method to lower the approach temperature. This study developed a control algorithm for cooling tower low-approach temperature. The approach temperature changes within the same load, ambient conditions according to the liquid-to-gas ratio (LGR), which is the operating condition of the cooling tower system. It found that the lower the LGR, the lower the approach temperature could be secured. As the approach temperature is lowered, it is expected that the efficiency of the chiller and cooling water pump will be improved. |
