摘要：
A method for controlling freezing capacity of a variable-frequency freezing AC ice-water system separates the freezing capacity of each individual requirement end so as to reduce sudden or peak concentrating freezing demand and relieve variable-frequency load demand, and defines operating procedures corresponding to different requirement ends, respectively, wherein each of the operating procedures has a corresponding high-low temperature range that can be used as a temperature buffer zone so as to redistribute supply of the freezing capacity to each requirement end, thereby allowing the compressors thereof to operate smoothly and thus achieve energy saving as a result. The drawbacks of damaged pipelines are overcome that cause deficiency in freezing capacity as encountered in prior techniques.
