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.

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.

A system for automated integration of events, configured for use in a building with a network system, includes a plurality of surveillance systems, a processing center connected to the surveillance systems through the network system and a user device connected to the processing center through the network system. The surveillance systems are adapted to monitor various kinds of irregular events occurring in the building and the surroundings thereof and output corresponding event messages through the network system. The processing center receives the event messages in a preset receiving mode and further classifies and analyzes the event messages. The user device allows users to input filtering conditions and enables the processing center to integrate the classified and analyzed event messages according to the input filtering conditions so as to generate composite filtered messages to be displayed on the user device, thereby achieving efficient acquisition and integration of the event messages.
