Test device and test method thereof for automobile air-conditioning system

Abstract

The invention discloses a test device and a test method thereof for an automobile air-conditioning system, the test device comprises an intermediate connecting tooling, one end of the intermediate connecting tooling is connected with one end of a pressure sensor, the other end of the pressure sensor is connected with a data recording instrument, and the data recording instrument can collect pressure and temperature signals of the automobile air-conditioning system through the pressure sensor and a temperature probe; and the other end of the intermediate connecting tooling is connected with a fast charge joint connected with a whole vehicle pipeline, the intermediate connecting tooling is in a crisscross structure, a through hole structure is formed in the axial direction, the diameter of an inner hole in the middle position is less than that of the inner holes at two ends, and the diameter of the inner hole at one end of the intermediate connecting tooling, which is connected with thepressure sensor is less than that of the inner hole at one end of the intermediate connecting tooling, which is connected with the fast charge joint. The test device for the automobile air-conditioning system with the structure can collect relevant important parameter indexes of the automobile air-conditioning system in a real-time manner, thereby evaluating the performances of the air-conditioning system in a very objective and real-time manner.

Description

technical field [0001] The invention relates to the field of automobile air conditioners, in particular to a test device and a test method for the automobile air conditioner system. Background technique [0002] In today's society, people pay more and more attention to environmental protection, product cost reduction and production efficiency. In the field of air conditioning in the automotive field, the evaluation of air conditioning systems is also particularly important. In the prior art, if you want to collect the temperature and pressure signals of the air conditioner in a timely, real-time and accurate manner, you can only collect the pressure manually through the ring mold chamber and use the pressure gauge. There is no one-to-one correspondence between the temperature and the pressure. There is some error in the pressure you see. Because the whole vehicle needs to enter the ring mold room, and the ring mold room is only an experiment, which cannot reflect the actual...

Problems solved by technology

In the prior art, if you want to collect the temperature and pressure signals of the air conditioner in a timely, real-time and accurate manner, you can only collect the pressure manually through the ring mold chamber and use the pressure gauge. There is no one-to-one correspondence between the temperature and the pressure. There is a certain error in the pressure seen

Because the whole vehicle needs to enter the ring mold room, and the ring mold room is only an experiment, which cannot reflect the actual driving process of the whole vehicle on the road. The actual road conditions such as mountain roads and high slopes cannot be simulated by the laboratory in the most realistic way. As a result, it cannot reflect the effect of the air conditioner in the actual driving of the vehicle in the most effective way.

Another: Because the ring mold room costs a lot, a ring mold test has high requirements on temperature and humidity; in the room, special treatment is required for the exhaust gas of the whole vehicle; therefore, every time you want to collect data related to the air conditioner The cost is huge, and it is also restricted by objective factors such as ring mold room equipment, personnel, and site, so it cannot be collected at any time
