Abstract

The present invention proposes an air conditioning system adjustment method and system based on weather forecast, belonging to the technical field of air conditioning energy saving. The method includes: collecting current indoor and outdoor temperature and humidity information, and weather forecast information within a specified time; judging the weather forecast Availability of information; use the weather forecast information to determine the cooling load required for indoor temperature adjustment, and adjust the control strategy of the air-conditioning system to make the indoor temperature reach the specified preset parameters within the specified time, and generate a timetable and set it in advance Sampling time point, detect the actual outdoor temperature information at the early sampling time point, compare the actual temperature information with the weather information obtained in advance, and determine whether to re-determine the cooling load and preset parameters according to the comparison result. The system includes modules corresponding to the steps of the method.

Description

technical field [0001] The invention provides an air conditioning system adjustment method and system based on weather forecast, belonging to the technical field of air conditioning energy saving. Background technique [0002] The current air-conditioning energy saving generally adopts PID control and load forecasting to adjust the air-conditioning system. However, the air-conditioning system, especially the central air-conditioning system is a complex system with time-delay, time-varying, non-linear and large inertia, which is difficult to describe with precise mathematical models or methods. For the air-conditioning system in the subway station, the factors affecting the indoor temperature of the subway station are the outdoor air temperature, light intensity, passenger flow, heat generated by train braking, and equipment heating, among which the main influencing factor is the outdoor temperature. Due to the time-varying dynamic characteristics of the central air-conditio...
