Embodiment Construction

[0019] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0020] Such as figure 1 As shown, an air-conditioning unit is provided on each compartment of the rail vehicle, and a fresh air inlet is provided in the air-conditioning unit, and the fresh air in the environment outside the car is sucked from the fresh air inlet, and an electric fresh air regulating valve 4 is set at the fresh air inlet. The opening degree of the electric fresh air regulating valve 4 is controlled by the fresh air flow control module 3 arranged in the air conditioning control system 5 .

[0021] A weight detection mechanism 6 for detecting the weight of the vehicle is arranged on the vehicle body, and a weight real-time monitoring module 2 is correspondingly arranged in the central control unit 1 of the vehicle driver's cab, and the weight detection mechanism 6 is connected with the weight real-time monitoring module 2 signals....

Abstract

The invention relates to a control method and a control system for the air-conditioning fresh air of a rail vehicle. A vehicle body is provided with a weight detection mechanism for detecting the weight of the vehicle; the weight detection mechanism transmits a detection signal to a central control unit; the central control unit processes the detection signal received from the weight detection mechanism, converts the detection signal into a corresponding weight signal, and transmits the weight signal to an air-conditioning control system; and the air-conditioning control system converts the weight signal into the number of passengers according to the weight of the vehicle to control the opening of a fresh air regulating valve. The number of the passengers is determined according to the weight of the vehicle, and the opening of the fresh air regulating valve in an air-conditioning system is controlled by gears, so that the aim of controlling fresh air amount is fulfilled, energy is saved, consumption is reduced, and the control method is simple, safe and reliable, and easy to operate.

Description

technical field [0001] The invention relates to an air-conditioning fresh air control system, in particular to an air-conditioning fresh air control system applied on rail vehicles. Background technique [0002] Due to the limitation of operating conditions and the reduction of air-conditioning load and energy consumption, urban rail vehicles have high airtightness requirements. In order to meet the sanitary conditions and ventilation requirements in the compartments, fresh air systems are generally used to send fresh air to each compartment. Each car of the rail vehicle is equipped with an air-conditioning unit. The air-conditioning unit is equipped with a fresh air inlet. The fresh air inhaled from the outdoor environment is mixed with the return air in the car and then enters the air-conditioning unit. After cooling, it enters the car. While maintaining the temperature in the cabin, the freshness of the air in the cabin is always maintained. [0003] The personnel load o...
