Air conditioner noise testing method

Abstract

The invention provides an air conditioner noise testing method. A noise laboratory for noise testing is included. The noise laboratory is divided into a noise laboratory indoor area and a noise laboratory outdoor area, and an air conditioner indoor unit and an air conditioner outdoor unit are separately arranged in the noise laboratory indoor area and the noise laboratory outdoor area, and the airconditioner indoor unit is connected with the air conditioner outdoor unit; pickups used for testing are separately and uniformly arranged in the noise laboratory indoor area in a high-middle-low multi-point distribution mode to perform noise collection test, and the result is output. According to the air conditioner noise testing method, the real noise condition of air conditioners in differentstates of users can be tested. The testing result is accurate, and the real conditions of air conditioner noise experienced by the users in different states can be effectively reflected.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a method for testing noise of air conditioners. Background technique [0002] With the development of society and the improvement of people's living standards, people have higher and higher requirements for the noise quality of air conditioners. At present, the noise tests of air conditioners and other products by domestic and foreign scientific research institutions and home appliance companies are all carried out in professional semi-anechoic chambers or full-anechoic chambers. The test method is to place the outdoor unit and the indoor unit of the air conditioner in two laboratories 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 transmitted noise generated when some outdoor units are working. [0003] However, when the air conditioner is actually used, it is installed on...

AI Technical Summary

Problems solved by technology

This detection method can only detect the noise of the indoor unit itself and the transmission noise generated by some outdoor units when they 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 generate resonance, which will cause obvious low-frequency noise in the room. And the noise has directivity and peak-to-valley effect

The existing test technology is very different from the actual use environment of the air conditioner. It is impossible to test the noise generated by this resonance. The test error is large and the result is inaccurate. Some air conditioners pass the test by the existing method, but they will produce serious noise pollution in actual use. , affecting user experience and causing customer complaints

[0004] Therefore, the traditional method of testing noise in a professional semi-anechoic room according to the national standard method can no longer meet the real demands of customers for noise.

The fundamental reason is that the traditional semi-anechoic room noise test method is out of the customer's real scene, and the test results can no longer reflect the actual situation of the air conditioner in the customer's home
