Embodiment Construction
[0023] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0024] Such as figure 1 and figure 2 As shown, a combined air-conditioning and ventilation test bench includes a closed space 1, a test compartment 2 is placed in the closed space 1, and the test compartment 2 is placed on a test stand 8, so that the vehicle body floor of the test compartment 2 is about There is a distance of 2m, which is convenient for the test and installation of the air duct under the car, and it is also convenient for the test personnel to pass through. The corresponding auxiliary interface is designed according to the specific ventilation system under the car. The test stand 8 adopts a two-point support structure in order to completely simulate the underbody structure of the current vehicle, and facilitate the simulation experiments of air-conditioning ducts and equipment compartments under the vehicle in the future.

The invention relates to an air conditioning ventilation combination test bench which comprises a closed space, a test carriage, a set of air conditioning units, a plurality of measurement devices, a control unit and a data analysis unit, wherein the test carriage is arranged in the closed space and is fixed on test bench position, a vehicle duct used for simulating an existing vehicle is detachably installed on the test carriage, the set of air conditioning units is installed independent of the test carriage and is connected with the corresponding vehicle duct installed on the test carriage through an air supply interface and an air return interface, and an air supply fan and an air return fan are respectively arranged on an air supply duct and an air return duct of the air conditioning unit. The test bench has strong universality and can be used for simulating internal structures of various traffic conveyances; and with adoption of the invention, the vehicle duct used for simulatingthe existing vehicle is constructed on the test carriage, and test and design early verification are carried out on an air conditioning ventilation system in a space which is completely consistent with a material object according to variation of vehicle types, vehicle interior layout, ducts, installation modes of the air conditioning unit.
Description
technical field [0001] The invention relates to an air-conditioning and ventilation combined test bench, which is suitable for conducting experimental research and pre-design verification on air-conditioning and ventilation systems of various rail vehicles, and belongs to the technical field of rail vehicle body manufacturing. Background technique [0002] In order to maintain a relatively uniform and stable temperature, humidity, air velocity and air cleanliness in the train compartment to meet the requirements of passenger comfort, the air in the train must flow reasonably. Therefore, the air conditioning and ventilation system is an important component of the environmental control system in the train. part. [0003] Judging from the air conditioning and ventilation systems of rail vehicles at home and abroad, although the methods vary greatly, most of them can meet the purpose of uniform temperature field and velocity field in the car, because in-depth research and carefu...
