Method for intelligently adjusting subway ventilation air conditioner

Abstract

The invention provides a method for intelligently adjusting a subway ventilation air conditioner. The method comprises the following steps of S1, collecting parameters of at least one of an internal environment of a subway, an external environment of the subway and an operation state of subway equipment through a data collection module; S2, performing availability judgement on the parameters through a logic analysis module; S3, performing type judgement on the current operation time of the subway to determine whether the current operation time belongs to an air-conditioning season or a non-air-conditioning season; S4, based on a result of determining whether the current operation time belongs to the air-conditioning season or the non-air-conditioning season, adjusting the work states of different kinds of hardware equipment of the subway air conditioner through an equipment control module. In this way, by means of the method, real-time intelligent control and reasonable frequency adjustment are achieved, the comfortable environment of a station can be maintained, the energy consumption of the air conditioner can be lowered, reasonable ventilation and intelligent regulation are achieved, the comfortable waiting area environment is created for passengers accordingly, and energy waste is avoided.

Description

technical field [0001] The invention relates to the technical field of ventilation and air conditioning control, in particular to a method for intelligent adjustment of subway ventilation and air conditioning. Background technique [0002] With the development of the economy, the power consumption in the country is increasing continuously. As a means of transportation, the subway not only accounts for an increasing proportion of daily travel, but also occupies a considerable proportion in energy consumption. As a subway ventilation and air conditioner that adjusts the comfort of the subway, the energy consumption of its system operation accounts for 30% to 40% of the total energy consumption of the subway, so there is still a lot of room for development in terms of energy saving for subway ventilation and air conditioning. The existing subway ventilation and air conditioning is mainly controlled by BAS. The BAS control strategy is relatively simple and single. It does not co...

AI Technical Summary

Problems solved by technology

The existing subway ventilation and air conditioning is mainly controlled by BAS. The BAS control strategy is relatively simple and single. It does not consider the impact of passenger flow on the station environment. It needs to manually set the control strategy. With the change of seasons, weather, passenger flow and other uncertain factors, subway The ventilation and air conditioning cannot be adjusted in time, and the temperature of the subway station hall and platform will be too low or too high, which will reduce the comfort; although the subway ventilation and air conditioning has applied frequency conversion technology, BAS cannot make the ventilation and air conditioning system run efficiently according to the load required by the station. The ventilation and air conditioning system of the subway still consumes a lot of energy, and there is room for energy saving
