Embodiment Construction

[0039] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0040] Load control is an important control strategy of the central air-conditioning system, and weather forecast data is the basis of load forecast. Therefore, the accuracy of weather forecast data is an important factor to improve the accuracy of load control, and it is also the key to improving the energy-saving control effect of the central air-conditioning system.

[0041] The objects of the method for predicting weather data in the present invention, that is, weather data, include but are not limited to temperature, humidity and the like. For the convenience of description, in the...

Abstract

The invention relates to a method and a system for predicting meteorological data. The method comprises: S1, obtaining a predictive meteorological coefficient of a specific time point of a predicted day according to actual meteorological data of a specific time point of each day, the highest meteorological data of each day, and the lowest meteorological data of each day within a past preset time period; S2, obtaining predicted meteorological data of the specific time point of the predicted day according to the predictive meteorological coefficient of the specific time point of the predicted day, the highest meteorological data of the day before the predicted day, and the lowest meteorological data of the day before the predicted day; and S3, correcting the predicted meteorological data of the specific time point of the predicted day according to the actual meteorological data of the specific time point of the predicted day, and correction weight data, thereby obtaining corrected meteorological data of the specific time point of the predicted day. By adopting the technical solution of the method for predicting the meteorological data, the meteorological data of a place where a central air-conditioning system is predicted in advance, and a load control policy for the central air-conditioning system is optimized to realize finer and more accurate control, and an effective energy-saving effect thus can be achieved.

Description

technical field [0001] The invention relates to the field of central air-conditioning, and more specifically relates to a method and system for predicting meteorological data for improving the load control accuracy of a central air-conditioning system. Background technique [0002] The energy consumption of the central air-conditioning system accounts for about 30%-50% of the total energy consumption of the building. Reducing the energy consumption of the central air-conditioning system through control or management has a positive impact on reducing the carbon emissions of the entire building. The "Dash central air-conditioning energy-saving control system EMC007" independently developed by DAS Intelligent Co., Ltd. has been applied to many projects since it has realized the functions of frequency modulation of the central air-conditioning system water pump and the most complex system group control, and verified the energy-saving effect And reliability, bring very good benef...
