Multi-split air-conditioning system control method based on prediction

Abstract

The invention relates to a multi-split air conditioning system control method based on prediction. The method comprises the steps that firstly, the temperatures and humidity outside a building are predicted, and the space enclosing structure load and the solar radiation load of an air conditioning system are calculated; secondly, the periodic law of the number of people inside the building is predicted; thirdly, the operating time of the air conditioning system is predicted; fourthly, operating parameters including the outdoor unit wind speed, the compressor rotating speed, the refrigerant flow rate, the indoor unit wind speed and wind amount, and the indoor unit flow rate are monitored in real time; fifthly, the temperatures and humidity outside the building, the number of people in the building, the operating parameters and hourly COPs in multiple sampling periods are counted up as a training sample, a statistical or machine learning method is adopted for calculating all characteristic factors, comfort pre-control time and temperatures, and operating parameters corresponding to optimal COPs; and sixthly, the operating parameters corresponding to the optimal COPs in the to-be-controlled time points are predicted, and thus, the system operating parameters and pre-control time are adjusted. According to the multi-split air conditioning system control method based on prediction,the control precision is high, and the control comfort and energy-saving effect are improved.

Description

technical field [0001] The invention relates to the technical field of air-conditioning regulation, in particular to a prediction-based multi-connected air-conditioning system regulation method. Background technique [0002] In my country, building energy consumption accounts for about 30% of the total social energy consumption, and 50% of building energy consumption comes from air conditioning systems. Therefore, reducing air-conditioning energy consumption has important strategic significance. [0003] Multi-connected air conditioners have been favored by consumers since they came into the market. Compared with traditional air conditioners, multi-connected air conditioners have significant advantages: using a new concept, integrating multiple high-tech technologies, intelligent control technology, multiple health technologies, energy-saving technologies and network control technologies, etc., to meet the needs of consumers. The requirements for comfort and convenience av...

Problems solved by technology

Although these methods can solve part of the energy consumption problem, there are still some shortcomings: either the lack of the influence of outdoor temperature and humidity changes, or the lack of the influence of periodic changes in the number of people and the adjustment of the pre-running time and operating conditions of the air conditioner, they can only be passive. achieve adjustment
