Control system and method based on air conditioning load prediction

Abstract

The invention provides a control system and method based on air conditioning load prediction. The control system comprises a datum collector, an air conditioning load predictor, a current air conditioning load computing unit and an air conditioning load predicting unit. The datum collector is used for collecting indoors temperature and humidity information and outdoors temperature and humidity information of the site where an air conditioner is located according to preset time intervals, and transmitting the information to the air conditioning load predictor. The air conditioning load predictor comprises a prediction step-size regulating device which is used for regulating a prediction step-size according to the indoors temperature and humidity information of the site where the air conditioner is located, preset standard values of indoor temperature and humidity and the outdoors temperature and humidity information, wherein the initial value of the prediction step-size is preset. The current air conditioning load computing unit is used for obtaining a current air conditioning load datum according to the difference value between the indoors temperature and humidity information of the site where the air conditioner is located and the preset standard values of indoor temperature and humidity. The air conditioning load predicting unit is used for predicting an air conditioning load value according to the current air conditioning load datum and the prediction step-size. The control system and method based on the air conditioning prediction are capable of controlling the temperature and humidity more accurately and achieving energy conservation to a great degree.

Description

technical field [0001] The invention relates to the technical field of control, in particular to a control system and method based on air conditioner load forecasting. Background technique [0002] Energy issues have been paid more and more attention to. At present, building energy consumption has accounted for more than 27% of the total energy consumption of the society. In buildings, the energy consumption of air conditioners accounts for more than 40% of building energy consumption. The energy saving of air-conditioning system in buildings has become a hot spot in the energy-saving field, and it is of great theoretical and practical significance to increase the research on air-conditioning energy-saving technology. [0003] With the development of science, the requirements for constant temperature and humidity in the production process are gradually increasing, such as knitwear, papermaking, medicine, food, data center computer room, etc. The central air-conditioning sys...

Problems solved by technology

The traditional automatic control method is to control through instruments, meters and regulators. This control method is simple and easy to implement, but the disadvantage is that the control accuracy is low and the failure rate is high.

[0004] To sum up, the air-conditioning system in the prior art may cause the problem of inconsistency between the cooling capacity and the load change, so the air-conditioning system cannot operate in the state of optimal energy efficiency, and cannot guarantee the requirements of constant temperature and humidity and energy saving
