This laboratory is the thermal performance laboratory of the fan coil unit, which can accurately measure the technical data of cooling, heat and air volume of the fan coil unit. At the same time, it can also be used for other standard operating conditions related tests and extended tests, providing a complete set of test means for customers to meet the requirements of product sampling inspection and product development (matching).
The laboratory is composed of a working room to meet the needs of the fan-coil air conditioner laboratory in working conditions. The room is equipped with air volume.
