This laboratory is the noise performance laboratory of the fan coil unit, which can accurately measure the technical data of the noise of the fan coil unit, and provide a complete set of test means for customers to meet the requirements of product sampling inspection and product development (matching).
The laboratory consists of a semi-anechoic chamber to meet the environmental requirements of the fan coil air conditioner noise laboratory.
