Problems solved by technology

Therefore, it is very difficult to obtain accurate and standardized measurements
Because the temperature measurement method is not only difficult to arrange the temperature acquisition system, but also requires maintenance of the temperature sensor itself, it is very difficult to implement and has not been widely used in airlines.

Embodiment Construction

[0036] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0037] The key point that the on-board air-conditioning system is different from the civilian air-conditioning system is that no refrigerant is used in the system. The onboard air conditioner directly uses aircraft engine bleed air, APU bleed air or a separate compressor to provide high temperature and high pressure air for the onboard air co...

Abstract

The invention relates to an onboard air conditioning system test device. The device comprises sound receiving equipment and sound processing equipment, wherein the sound processing equipment processes running noises of an onboard air conditioning system and assesses a running state of the onboard air conditioning system; and the running noises are sampled from the sound receiving equipment.

Description

technical field [0001] The invention relates to the field of aviation technology, in particular to a test device and a test method for an on-board air conditioning system. Background technique [0002] The air-conditioning system on board directly affects the comfort of passengers in the aircraft. In the daily maintenance of the aircraft, especially when the crew reports that there is a problem with the air conditioner, it is often necessary to test the working status of the onboard air conditioning system. [0003] The most direct way to test the air-conditioning performance is to collect the temperature of each key part of the air-conditioning system of the aircraft, and determine the operating performance of the air-conditioning system by drawing an inverse Karnaugh map or using the difference method. However, the temperature measurement method is only an idealized test method, because this method needs to install temperature sensors and power lines and / or signal transmi...
