Train air conditioner control method achieving quick response

Abstract

The invention provides a train air conditioner control method achieving quick response. The method comprises the steps that 1, passenger weight data of all train carriages is acquired, and an air conditioner load module of a train air conditioner control system calculates all train carriage load values, a fresh-air fan rotation speed value and a fresh-air air valve switching-on degree value which are needed by air conditioner simulation; 2, supply-stroke refrigerant temperature data, back-stroke refrigerant temperature data and back-stroke refrigerant flow data of air conditioners of all train carriages are acquired; 3, the train carriage load values, the fresh-air fan rotation speed value and the fresh-air air valve switching-on degree value which are needed by computational simulation are compared, and the refrigerating capacity, the fresh-air fan rotation speed and the fresh-air air valve switching-on degree of the train air conditioner control system are regulated by comparing the load state in real time. Compared with the method of controlling the air conditioner system load by monitoring the temperature in the carriages, the method has the advantages that feedback of the air conditioner system load is quicker and more accurate, and the time needed when a comfortable riding environment is provided for passengers is shortened.

Description

technical field [0001] The invention relates to the field of electromechanical integration control, in particular to a rapid-response train air-conditioning control method. 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 compartment, and the regulations on interior design para...

Problems solved by technology

First of all, it does not explain the statistical method of the number of passengers

Moreover, the passengers in the compartment are mobile, and there are also those who are sitting on the seat and standing. If the seat sensor is used to monitor the number of passengers, there must be a large error. In addition, the passengers in the adjacent two compartments will also move, so , the number of passengers is difficult to achieve

Secondly, adjusting the amount of fresh air according to the temperature can indeed achieve the purpose of energy saving, but this needs to be at the expense of the health and comfort of passengers
