Embodiment 1

[0039] This embodiment improves the semi-anechoic room noise testing device in the prior art, and provides an air-conditioning noise testing device, such as Figure 3-5 As shown, it includes an outdoor noise room 1, an indoor noise room 2, and a boundary wall 3 arranged between the indoor noise room 2 and the outdoor noise room 1. The outdoor noise room 1 is provided with an external machine installation platform 4, and the external machine The installation platform 4 is connected with the boundary wall 3 between the indoor noise chamber 2 and the outdoor noise chamber 1. When the air conditioner is in use, the external unit installation platform 4 supporting the external unit receives the vibration of the air conditioner external unit, and passes the vibration directly through the The boundary wall 3 is transmitted to the room, so that the boundary wall 3 generates resonance noise. The air conditioner noise test device formed in this embodiment can accurately simulate the real...

Embodiment 2

[0056] Such as Figure 5 As shown, this embodiment provides a method for testing air-conditioning noise on the basis of Embodiment 1, which specifically includes the following steps:

[0057] S1: Put the outdoor unit 8 of the air conditioner on the support platform 5, hang the indoor unit on the boundary wall of the indoor noise room, connect the indoor unit and the outdoor unit with the connecting pipe of the indoor and outdoor unit, pump the vacuum, and open the valve of the outdoor unit;

[0058] S2: Move the platform grille 6 to the front of the outdoor unit, and adjust the distance D between the platform grille 6 and the front of the grille of the outdoor unit according to the standard;

[0059] S3: setting the noise testing device to the first working condition;

[0060] S4: Turn on the air conditioner and test the noise of the indoor unit and the noise of the outdoor unit. The operating frequency of the air conditioner is measured every 2Hz from 20Hz to 110Hz;

Abstract

The invention provides an air conditioner noise testing device and method. The air conditioner noise testing device comprises an outdoor noise chamber, an indoor noise chamber and a boundary wall arranged between the indoor noise chamber and the outdoor noise chamber. An outdoor unit installation platform is arranged in the outdoor noise chamber and used for installing an air conditioner outdoor unit, and the outdoor unit installation platform is connected with the boundary wall. Compared with a semi-anechoic chamber in the prior art, the air conditioner noise testing device provided by the invention can simulate the real installation condition of the air conditioner in a user home, guarantees that vibration of the air conditioner outdoor unit can effectively cause wall resonance, and transmit resonance noise to the indoor side, so the noise test result is consistent with real noise of a user site, and the result is more accurate and reliable.

Description

technical field [0001] The invention relates to the technical field of electric appliance testing, in particular to an air conditioner noise testing device and testing method. Background technique [0002] At present, home appliance companies conduct noise tests on air conditioners and other products in professional semi-anechoic or fully anechoic rooms. The advantage is that there is no external noise interference during the noise test, and the test value is more objective. However, its main disadvantage is that the noise test results often cannot truly reflect the actual noise of the air conditioner in the customer's home. For example, some air conditioners pass the noise test in the semi-anechoic room, but there are a lot of customer noise complaints after sales. [0003] Such as figure 1 As shown, the noise of traditional air conditioners is carried out in a semi-anechoic room. The external unit cannot be placed on the installation platform like the customer’s home, b...
