Abstract

The invention discloses an energy-saving control system and an energy-saving control method, based on vectorization analysis, for a heating and ventilation circulating water system. The energy-savingcontrol system comprises a water temperature transmitter, a working condition parameter sampling unit, a parameter monitoring unit, a variable-frequency control calculating unit, an output inverting unit, a frequency converter and a circulating water pump. By adopting a membership degree vector decomposition method, a sampling object value is decomposed into a multi-dimensional membership degree vector, and at the moment the sampling object changes are also decomposed to a plurality of dimensionalities. A membership degree function is reasonably selected to make sure that the change value of the sampling object is reflected to different sub-vectors of the membership degree vector in different value ranges, and thus an effect of obviously showing variation tendency. The system and the method disclosed by the invention realize look-ahead assuagement of state transition of the system by assuaging the tendency. Slowly-responding system variables in an air conditioning system are subjectedto fuzzy vector analysis so as to amplify the system state transition tendency reflected in small-amplitude changes of the system variables, and the running state of the system is regulated accordingto the tendency so as to maintain the running stability.

Description

technical field [0001] The invention relates to an energy-saving control system and method for a HVAC circulating water system based on vectorization analysis. Background technique [0002] The current energy-saving control method of the central air-conditioning water cycle control system usually uses follow-up control to adjust the operating frequency of the water pump according to the deviation between the measured parameter value and the control target value, so as to achieve the purpose of energy-saving operation. [0003] Due to the large time lag in the air-conditioning system, the deviation between the measured parameter value and the control target value at a certain moment can only reflect the comprehensive operation result of the air-conditioning system at this time, and cannot reflect the real change trend of the system. When the follow-up control method passively follows the deviation value and continuously adjusts the frequency, the accumulation of system oversh...
