Air conditioner detecting device

Abstract

The embodiment of the invention discloses an air conditioner detecting device and relates to the technical field of electronic engineering. The problem that a large noise is generated when nitrogen is discharged out of an air conditioning pipe can be solved. The air conditioner detecting device includes an inflatable branch, at least one air conditioner branch, an exhaust branch and a control module; the inflatable branch, the at least one air conditioner branch and the exhaust branch are all connected with the control module; the at least one air conditioner branch is connected with an air conditioner, the inflatable branch includes a nitrogen bottle, and the exhaust branch includes a capillary tube; The control module is used for controlling the inflatable branch to be in the conducting state, controlling the nitrogen bottle to output nitrogen and controlling the exhaust branch to be in a closed state after the at least one air conditioner branch is connected with the air conditioner and for controlling the inflatable branch to be in the closed state and controlling the nitrogen bottle to stop nitrogen outputting after the value of the pressure in the air conditioner is larger than a first pressure value; after the first preset time, the exhaust branch is controlled to be in a conducting state. The air conditioner detecting device is applied in the installation and testing of air conditioners.

Description

technical field [0001] The embodiments of the present invention relate to the field of electronic technology, and in particular, to an air conditioner detection device. Background technique [0002] The air conditioning pipeline in the air conditioner is used to support the circulation of fluid (eg, refrigerant) during the use of the air conditioner. In order to ensure the tightness of the air-conditioning pipeline during the use of the air conditioner, the tightness of the air-conditioning pipeline can be tested when the air conditioner is installed, or the tightness of the air-conditioning pipeline can be tested regularly during the use of the air conditioner. . [0003] In the prior art, the air-conditioning pipeline can be filled with nitrogen and kept under pressure to check the airtightness of the air-conditioning pipeline. Specifically, the inspector can connect the nitrogen filling and pressure maintaining equipment (including the nitrogen cylinder) to the air cond...

AI Technical Summary

Problems solved by technology

[0004] The problem that exists is, in the prior art, in the above-mentioned process of "exhausting the nitrogen in the air-conditioning pipeline", since the pressure of the nitrogen in the air-conditioning pipeline is much greater than the standard atmospheric pressure (i.e. 1.013×10^5 Pascal (English: Pascal, Abbreviation: Pa)), that is, there is a large pressure difference between the nitrogen in the air-conditioning pipeline and the air; therefore, there will be a lot of noise when the nitrogen in the air-conditioning pipeline is discharged into the air
