Train air conditioning load control method based on passenger weighing system and train air conditioning load confirming method

Abstract

The invention discloses a train air conditioning load control method based on a passenger weighing system and a train air conditioning load confirming method. The train air conditioning load control method based on the passenger weighing system comprises the following steps of S1, obtaining passenger weight data of each train compartment and exerting an air conditioning load module of a train air conditioning control system to calculate a load value of each train compartment needed by air conditioner simulation; S2, obtaining supply path refrigerant temperature data, return path refrigerant temperature data and refrigerant flow data of an air conditioner of each train compartment, and exerting the air conditioning load module of the train air conditioning control system to calculate the load value of each train compartment, actually needed by the air conditioner; and S3, comparing the needed load value of each train compartment by calculation simulation and the actually needed load value of each train compartment, and adjusting refrigerating capacity of the train air conditioning control system through comparing the load states in real time so that passengers feel comfortable and the method is also energy-saving and consumption-reducing. Compared with the traditional method for controlling the load of the air conditioning system through monitoring the temperature in the compartment, the train air conditioning load control method disclosed by the invention is advantaged in that the feedback of the load of the air conditioning system is rapid and accurate.

Description

technical field [0001] The invention relates to the field of electromechanical integration control, in particular to a train air conditioning load control method and confirmation method based on a passenger weighing system. Background technique [0002] The design temperature in the compartments of urban rail transit and high-speed rail directly affects the comfort of passengers, but my country has not yet issued relevant regulations or standards to make regulations, most of which are based on the standards of the European Union of Railways, such as the initial use of UIC553-1990 The design temperature in the middle compartment is expressed as: [0003] t in =22+0.25×(t out -19) = 0.25t out +17.25 [0004] In the formula, t in - Air temperature inside the car, °C; [0005] t out - outside air temperature, °C. [0006] From this formula, it can be seen that the design temperature inside the compartment changes continuously with the ambient temperature outside the compa...

Problems solved by technology

[0010] The traditional cooling capacity control method of the traditional compartment air conditioner is to adjust the cooling capacity of the air conditioning system after the temperature in the compartment is monitored to rise or fall. Especially in the subway, the interval between stations is short, and the personnel in the train compartment The quantity changes quickly, and the feedback from the air-conditioning system is bound to lag from when passengers get on the bus to when the sensor monitors the temperature change.

In addition, the temperature monitoring in the compartment is greatly affected by the layout of the measuring points and the activities of people near the measuring points, so the control of the air conditioning load is not accurate
