碩士 === 國立屏東科技大學 === 機械工程系所 === 105 === In the industrial plant ice water system (Chiller, CHP, CDP, Cooling Tower) are power consumption equipment, and its power consumption ratio of the entire plant power consumption of the top three, ice water system design is different Of the planning choice, the first side of the ice water conditioning system is the concept of Trane in 1999, has been widely used in Europe and the United States, but in recent years in the country to get rid of the concept of stereotypes, the use of cases increased year by year. This study is aimed at the impact of power consumption on the primary side of the ice water system in the industrial plant. The most direct is the reduction of the power consumption of the ice water pump and the cooling water pump, but also the evaporation and condensation temperature for the ice water host, Changing the temperature difference between the water temperature and the evaporative temperature of the ice water will also affect the heat transfer of the evaporator, and it will also affect the performance coefficient of the ice water. The purpose of this study is to analyze the effect of the variable flow on the data, Best operating mode. The design of the primary side of the variable flow, so that the pump has more time in low water and low power consumption. Because the pump power consumption and the traffic is proportional to the characteristics of the third, so reduce the amount of water when there are often large energy efficiency, outside the wet bulb temperature lower energy efficiency is higher, so the effect of winter is particularly significant.
