Air Conditioning Cooling System Energy Saving Technology Research

As people requirements of comfort, the application of the central air-conditioningsystem has become quite common, but its drawbacks of high energy consumption hasbecome a matter of growing concern, the importance of energy analysis of theincreasingly obvious, and the cooling water system energy consumption an importantpart of the energy consumption of air conditioning systems. The main cooling systemand air-conditioning load and outdoor meteorological parameters, energy is the key atpart load conditions and outdoor parameters, the cooling system how to control it.The main idea of the study: each components of the cooling system and thetheoretical analysis of a mathematical model, based on the mathematical modelestablished, write module chillers, cooling water pumps and cooling towers in theTRNSYS simulation software environment. In the measured data and the preparationof the module on the basis of the above, each module is determined by the parameteridentification eventually build central air conditioning cooling system dynamicsimulation platform to simulate the energy consumption under different conditions,and to optimize the control, to find the most advantages.Central Institute for Energy Conservation Progress currently made for the airconditioning cooling system as well as the actual existence of the problem, this paperestablished a mathematical model of each component, and combined with thecorresponding "parameter optimization of range", based on the overall cooling systemenergy research, and2012in the outdoor environment parameter June1, and thebuilding at this time of the cooling load operation as the background, using TRNSYSestablished air conditioning cooling system simulation platform, respectively, for agiven amount of water constant air volume control, cooling water to the temperaturedifference between control and herein built on energy optimization control method wassimulated, the results show: optimized control of water and given constant air volumecontrol in this paper reaches12.9%compared to the saving rate, and the cooling waterto the temperature difference between the water and the fixed constant air volume control mode compared to only8.3%compared to the saving rate, which verify thefeasibility and energy efficiency issues.
