The intake grill includes a frame, bars, and a reinforcement capable of deforming the bars. The frame defines an outer edge of the intake opening. The bars are plate-shaped members spanned between portions of the frame to connect the portions to each other. The reinforcement elastically deforms the bars to generate reaction force therein.

A health protection system and a method for passengers on a train in a polluted indoor environment are provided. The health protection system includes a basic data acquisition module, an outdoor air quality prediction module, an indoor air quality prediction module, and a ventilation strategy generation module, wherein the basic data acquisition module acquires basic data; the outdoor air quality prediction module predicts outdoor air quality of the train; the indoor air quality prediction module predicts indoor air quality of the train; and the ventilation strategy generation module generates a ventilation strategy and achieves health protection of the passengers on the train. The method includes: predicting indoor and outdoor air quality data information of the train according to the acquired indoor and outdoor air quality data of the train; and generating a corresponding ventilation strategy according to the indoor and outdoor air quality data of the train.

Provided is a railway vehicle air-conditioning duct that is capable of achieving a more uniform in-cabin temperature distribution through more appropriate volume distribution of conditioned air. A railway vehicle air-conditioning duct that supplies conditioned air generated by an air conditioner into a cabin and that extends in a vehicle length direction at a vehicle ceiling part has: a main duct; a chamber duct; a branch duct; and a guide part. The guide part is lower in height than the main duct, extends to a branch duct from the main duct or a partition wall in the main duct in a vehicle width direction, and supplies to the branch duct a portion of the conditioned air supplied to the main duct.

An electrically operated vehicle includes a braking resistor in a heat sink cover. The heat sink cover has an air throughflow body having vent openings and an air throughflow direction perpendicular to a direction of travel of the vehicle. The heat sink cover includes an inlet flap on an air inflow side and an outlet flap on an air outflow side. An opening mechanism opens and closes the flaps. In the closed state, the flaps are oriented along the direction of travel and obliquely to the air throughflow direction. In a plan view of the vent openings, the vent openings are at least 90% covered by the flaps in the closed state and at most 60% covered by the flaps in the opened state. The flaps are disposed symmetrically to a vehicle center axis, and the vent openings are oriented parallel to side surfaces of the vehicle.

A fanless cooling system for particularly fail-safe and efficient cooling of electronic modular systems in vehicles, more particularly in rail vehicles, includes a preferably frame-shaped rack or assembly carrier for holding at least one module or assembly, more particularly a processor module having high-performance multi-core processors. A heat transport body can be mounted in a heat-transferring manner on a part or component of the module. The rack has at least one heat distribution body, to which the heat transport body can be fastened in a heat-transferring manner, preferably detachably, when the module having the part coupled to the heat transfer body is held in the rack. At least one heat tube is connected to the heat distribution body in a heat-transferring manner. An electronic modular system with a fanless cooling system is also provided.

The invention relates to a method for supplying air at a controlled temperature to a cabin (10) of a surface vehicle in which at least one air cycle device is used, comprising at least one motorised turbocompressor. The air inlet (16) of the turbine (14) is arranged to receive a compressed airflow from the compressor (15). At least one exchanger (20, 32) is interposed between the air outlet (19) of the compressor (15) and the air inlet (16) of the turbine (14). The air inlet (18) of the compressor (15) is arranged to receive air at a pressure greater than or equal to atmospheric pressure. The invention likewise relates to a surface vehicle comprising at least one such air cycle device.

Disclosed is a load-predicting and control system for a subway heating, ventilation and air conditioning system. In one aspect, a load-predicting and control system for a subway heating, ventilation and air conditioning system is provided. The system includes a basic database, a sensing system, a load predicting unit, and a controller; the basic database stores historical data; the sensing system provides measured data; the load predicting unit calculates a predicted load value of the subway heating, ventilation and air conditioning based on the historical data and the measured data, and transmits the predicted load value to the controller; the controller issues a control command based on the predicted load value. Also provided is a load-predicting and control method for the subway heating, ventilation and air conditioning system. The present disclosure solves problems such as poor accuracy of conventional load prediction and inadequate control of the air conditioning system.
