Railway vehicle air conditioner energy consumption testing device and method

Abstract

The invention discloses a railway vehicle air conditioner energy consumption testing device and method and belongs to the field of railway vehicle air conditioner testing. According to the technical scheme, the railway vehicle air conditioner energy consumption testing device comprises an outdoor side testing cell for simulating the environment outside a railway vehicle, a simulation testing box for simulating the environment inside the railway vehicle is placed in the outdoor side testing cell, the simulation testing box is connected with a tested air conditioner unit through an air supply channel and an air return channel, and a heating device and a humidifying device are placed in the simulation testing box so as to simulate thermal loads inside the vehicle. By means of the railway vehicle air conditioner energy consumption testing device and method, the problems that in an existing railway vehicle air conditioner energy consumption test, a real vehicle is needed, the testing time is long, the testing cost is high, and energy and materials are wasted are solved.

Description

technical field [0001] The invention belongs to the test field of rail car air conditioners, and in particular relates to a rail car air conditioner energy consumption test device and method. Background technique [0002] In train operation, except for traction, the energy consumption of air-conditioning units of rail passenger cars accounts for a large proportion. The power consumption of air-conditioning in each large railway passenger car is 20kW to 30kW, and the lighting, boiling water boiler, electric heat tracing, control system, etc. About 6kW, air conditioning power consumption accounts for 77% to 83%; each urban rail subway passenger car air conditioning power consumption is 30kW to 40kW, the lighting and control system in the car is about 4kW, air conditioning power consumption accounts for 88% to 91%. Therefore, reducing the energy consumption of rail car air-conditioning systems and improving the energy efficiency of air-conditioning units has become a key resear...

Problems solved by technology

[0005] Conducting tests on rail cars in the static thermal laboratory can obtain various data in a static state, and evaluate specific models and air-conditioning units. If the model and air-conditioning unit are changed, the accuracy of the evaluation will decrease

Therefore, in order to test and evaluate different vehicle types, laboratory tests must be carried out for each type of vehicle type, which brings difficulties to the evaluation work.

Since the passenger car manufacturing factory requires timely supply after receiving the rail passenger car manufacturing order, even if the suggestion for improvement is obtained through the energy efficiency test of the air-conditioning unit in the static thermal laboratory, there is not enough time for improvement for the factory. The result is difficult to apply
