Embodiment 1

[0042] like figure 1 , shown in 2, a kind of air-conditioning noise test method, wherein, comprise: a kind of novel noise laboratory for detecting noise, noise laboratory is made of floor, suspended ceiling structure 9 and body of wall 5, wherein a body of wall will The noise laboratory is divided into the noise laboratory indoor area 1 and the noise laboratory outdoor area 6. The noise laboratory outdoor area 6 simulates different environments in spring, summer, autumn and winter, so that the air conditioner can be adjusted according to different environments and conditions, according to customer requirements. Set up according to the needs, simulate the real situation, and test the noise generated by the air conditioner in the real situation. Moreover, the indoor area 1 and the outdoor area 6 are respectively provided with an indoor soundproof door 8 and an outdoor soundproof door 7; the setting of the indoor soundproof door 8 and the outdoor soundproof door 7 is for simulati...

Embodiment 2

[0068] The difference between this embodiment and the above embodiment is that the air conditioner indoor unit 3 and the air conditioner outdoor unit 4 are directly installed on the same wall, the air conditioner indoor unit 3 is installed in the test area through the installation frame, and the air conditioner outdoor unit 4 is installed in the test area through the installation frame Installed on the back of the wall in the outdoor zone 6 of the noise laboratory. Through the setting of the corresponding installation positions of the air conditioner outdoor unit 4 and the air conditioner indoor unit 3, the vibration generated when the air conditioner indoor unit and the air conditioner outdoor unit work together is guaranteed, and the real noise situation of the air conditioner is further reflected, thereby improving the accuracy of the product noise test. effectiveness.

Embodiment 3

[0070] The difference between this embodiment and the above embodiments is that the height D of the mounting frame of the air conditioner outdoor unit 4 is between 0.5 and 3.2 meters, and the distance dimension E between the two ends of the wall where it is located is between 0.9 and 5 meters. between. Preferably, the height D is between 0.8-2.6 meters; the distance E is between 1.5-4 meters. The setting of the installation position can better ensure that the vibration of the outdoor unit of the air conditioner can effectively stimulate the wall to resonate, thereby improving the real reflection of the noise of the air conditioner.

Abstract

The invention provides an air-conditioner noise test method. A noise lab for noise test is included, and divided into an indoor area and an outdoor area, an air-conditioner indoor set and an air-conditioner outdoor set are arranged and connected with the indoor area and the outdoor area of the noise lab respectively; and test recording devices are arranged in the indoor area of the noise lab uniformly in a multi-point laying manner. Via the method, noise conditions in the real condition of the air conditioner can be tested, a test result is accurate, and real conditions of the air-conditionernoise can be reflected effectively.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner noise testing method. Background technique [0002] At present, scientific research institutions and home appliance companies at home and abroad conduct noise tests on air conditioners and other products in professional semi-anechoic or fully anechoic rooms. The test method is to place the outdoor unit and the indoor unit of the air conditioner in two laboratories respectively to test the indoor noise when the air conditioner is running. This detection method can only detect the noise of the indoor unit itself and the transmission noise generated when some outdoor units are working. [0003] However, when the air conditioner is actually used, it is installed on the room or on the outdoor wall. The compressor will cause the outdoor unit to vibrate to a certain extent. At a specific frequency, it will coincide with the fixed frequency of the wall to gen...
