Air Conditioning Chilled Water System With Variable Flow Energy Analysis And Research

With the continuous development of size and function of public buildings, indoor environmental quality of large buildings has become increasingly dependent on central air conditioning significantly. Air-conditioning water system accounts for a significant proportion in the building energy consumption , However , due to air-conditioning system design is based on the most unfavorable environment , air-conditioning system has more than 90% of the time operation in part load operating conditions , Transformation of to variable flow based on dynamic building load is an important direction of building energy conservation research fields。This paper mainly studies the performance of the fan coil and the chillers in variable flow water system,the same time, several control methods of variable flow system are compared and analyzed,finally,,analysis of the operation energy-saving potential of the pump and the unit under variable flow transformation and give an optimization analysis to the program and control strategy of unit with an example of a variable flow transformation of an existing systems。...
