Exergy Analysis of Chiller Plant with Pre-cooling by Cooling Tower and Conventional Chiller Plant

In order to reduce the energy consumption of chiller plant at high temperature water source conditions,this paper presents the control strategy for pre-cooling high-temperature water with cooling tower.In order to explore the feasibility of this control and energy-saving potential,the exergy were analysis of the conventional chiller plant and new chiller plant with pre-cooling by cooling tower.The results show that when the water temperature is higher than a certain value,the exergy energy efficiency would be increased and the energy consumption of chiller plant with pre-cooling can be decreased,the saving energy would increase with water temperature.
