Study of Frequency Conversion Energy-Saving Reconstruction for Central Air-Conditioning

Abstract:

Water system is one of the significant compositions with large power consumption in air-conditioning equipment. From viewpoint of energy-saving, the variable frequency operational principle of the water system is analyzed, the merits and demerits of operating water system under power frequency or variable frequency are compared, and the control principle of the energy-saving revamping project is introduced. In addition, combining with the specific project, the benefit of energy-saving for the water system is analyzed. The result shows that after revamping, the air-conditioning system runs properly, both the indoor temperature and humidity meet the specifications; the revamping technology offers significant energy-saving effects.
