AIR-CONDITIONING WATER SYSTEM FREQUENCY CONVERTER ENERGY SAVING ANALYSIS AND APPLICATION

For selection of water pump in central air conditioning system,volume and water head are decided normally based on the maximum cooling load,the system often works on part load in actual operation,the system water volume will be larger because of this,and the more energy will be wasted.According to calculation and analysis of the air-conditioning water system,provided that design and apply frequency converter control system in the(air-conditioning) water system to reduce the energy consumption,the control system works well,and it reaches the forecast result.The practice proves that this control system could be applied widely.
