  • Patent number: 8733115
    Abstract: 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.

  • Patent number: 8528347
    Abstract: A method for controlling the freezing capacity of a fixed-frequency freezing AC ice-water system, by using temperature buffer difference of individual requirement ends to control the number of operating compressors in a fixed-frequency chiller and make each of the operating compressors have a usage rate close to 100%. Further, various operating procedures are defined for the requirement ends and each of the operating procedures has an individually defined high-low temperature range such that the freezing capacity supply cycle or startup cycle of the fixed-frequency chiller can be adjusted by using the high-low temperature ranges of the operating procedures as temperature buffer strips, thereby allowing the compressors in the fixed-frequency chiller to operate collectively in order to save energy.
