Abstract

The invention provides an outdoor unit noise testing device and method. The device comprises a detection chamber, a data processing device, a data acquisition device and a power supply device. The data processing device and the power supply device are arranged outside the detection chamber; the data processing device is connected with the power supply device; the detection chamber comprises an enclosing wall, a ceiling and a partition wall. The enclosing wall is matched with the ceiling, and the partition wall is matched with the enclosing wall and the ceiling and divides the detection chamberinto an indoor side and an outdoor side; the air conditioner outdoor unit is arranged on the outdoor side, the indoor unit is arranged on the indoor side, the air conditioner outdoor unit is connected with the indoor unit, the data acquisition device is arranged on the outdoor side, the data processing device is connected with the data acquisition device, the power supply device comprises a variable-frequency power supply and a harmonic generator, the variable-frequency power supply is connected with the harmonic generator, and the harmonic generator is connected with the indoor unit. According to the outdoor unit noise testing device and method, the influence of power supply harmonics on outdoor unit noise testing is eliminated to the maximum extent, and the accuracy of outdoor unit noise detection is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an external unit noise testing device and method. Background technique [0002] With the popularization of air conditioners, the noise nuisance of air conditioners has become a hot and difficult research topic for various enterprises. The loud noise of the outdoor unit not only affects the customer itself, but also affects the sleep and rest of the customer's neighbors, bringing discordant factors to the neighborhood relationship. However, in the process of handling after-sales noise complaints, the applicant often found that when the customer brought the noisy machine back to the factory for retest, the retest result was often qualified. After research, it was found that the reason for the high noise of the customer's outdoor unit was that the harmonic content of the user's power supply far exceeded the national standard, and the conventional air-conditioning noise tes...
