Abstract

The invention discloses an energy-saving control system for an intelligent air conditioner, and a control method thereof. The system comprises a state detection unit used for acquiring the state information and the power information of each device in an air conditioning system, a processor, and a control unit used for outputting the optimal control strategy of the processor, wherein the processer clusters the state information through a Gaussian mixture model clustering module, and a linear regression fitting module establishes a polynomial-based linear regression fitting model for fitting the power of each device with regard to each clustering label, then predicates the total power consumption of the air conditioning system, and finally searches a control strategy through a genetic algorithm search module. According to the system and the method, relationship is established between controllable variable control on the intelligent air conditioning system and the current state information of the devices on the basis of a multi-model fusion model of a Gaussian mixture model, a linear regression model and a genetic algorithm model; and the system has the beneficial effects of being high in reliability and obvious in optimization effect.

Description

technical field [0001] The invention relates to the field of air-conditioning energy saving, in particular to an air-conditioning energy-saving control system and method based on Gaussian mixture model, linear regression and genetic algorithm. Background technique [0002] With the global warming and the development of air-conditioning technology, more and more modern buildings use central air-conditioning to adjust indoor temperature and humidity. With the rapid advancement of the pace of "smart city" construction, the realization of intelligent control and energy saving of central air-conditioning has also been put on the agenda. However, only relying on the experience of technicians to regulate the central air-conditioning system, but the effect is not obvious. [0003] At present, a technical problem urgently needed by those skilled in the art is: how to break through the limitation of central air-conditioning control only relying on the experience of the technicians. ...
