Embodiment 1

[0021] refer to figure 1 , the present embodiment provides a pressure test device for an automobile air-conditioning system, including a refrigerant tank 4, the refrigerant tank 4 is connected to one interface of the three-way valve 10 through a first connecting pipe 3, and the other two interfaces of the three-way valve 10 One of them is connected to the pressure transmitter 8 through the second connecting pipe 9 , the other of the other two ports is connected to the third connecting pipe 11 , and the third connecting pipe 11 is connected to the filling port joint 12 .

[0022] During the test, first use a vacuum pump to vacuumize the automotive air conditioner that needs to be tested. After the vacuuming process, connect the filling port joint 12 to the filling port of the low-pressure pipe of the automotive air conditioner. Open the refrigerant tank 4, and fill the refrigerant according to the amount of refrigerant designed for the automobile air conditioner through the fil...

Embodiment 2

[0026] refer to figure 1 , Embodiment 2 is based on Embodiment 1, and the difference with Embodiment 1 is:

[0027] In order to test the instantaneous pressure when the air-conditioning system is filled with refrigerant, the first connecting pipe 3 is provided with an air-conditioning low pressure gauge.

[0028] In order to conveniently control whether to add refrigerant and the speed of adding refrigerant, a valve 2 is provided on the first connecting pipe 3. When adding refrigerant, open valve 2, and close valve 2 when not adding refrigerant. By adjusting the opening size of valve 2 The rate at which refrigerant is added can be controlled. What is used in this embodiment is a manual valve, but it is not used to limit the present invention, and other valves, such as electric valves, can also be used for the valve 2 .

[0029] In order to obtain the pressure value conveniently, the output end of the pressure transmitter 8 is connected with the input end of the data acquisit...

Abstract

The invention discloses a vehicle air-conditioning system pressure test device, belonging to the technical field of vehicle tests. The vehicle air-conditioning system pressure test device comprises a refrigerant pot, wherein the refrigerant pot is connected with one interface of a three-way valve through a first connecting pipe, one of the other two interfaces of the three-way valve is connected with a pressure transmitter through a second connecting pipe, the other one of the other two interfaces is connected with a third connecting pipe, and the third connecting pipe is connected with a filler joint. By using the refrigerant pot and the pressure transmitter together, the purpose of monitoring air-conditioning pressure trend in real time when different amounts of refrigerant is filled is realized, and the vehicle air-conditioning system pressure test device has high foreseeability for the working state of the vehicle air-conditioning system.

Description

technical field [0001] The invention relates to the technical field of automobile testing, in particular to pressure testing equipment for an automobile air-conditioning system. Background technique [0002] With the rapid development of the automobile industry and the improvement of people's living standards, automobiles have begun to enter thousands of households. While people are pursuing the safety and reliability of automobiles, they also pay more attention to the requirements for the comfort of automobiles. Therefore, automobile manufacturers pay more and more attention to the test of the working status of auxiliary systems such as automobile air conditioning systems, and adjust the parameters of auxiliary systems through testing to ensure that the driver can have a more comfortable driving environment when the car is running. [0003] In order to ensure that the automotive air-conditioning system can produce a good cooling effect, manufacturers need to conduct a seri...
