Abstract

The embodiment of the invention provides a cabinet type unit testing device and method and a control cabinet, and relates to the technical field of cabinet type unit testing. The air speed of an air outlet of the cabinet type unit can be accurately controlled, the cabinet type unit comprises a fan cabinet and a fan arranged inside the fan cabinet, and the fan cabinet is provided with the air outlet and an air return opening. The method comprises the steps of measuring the real-time air speed of the air outlet; according to the real-time air speed of the air outlet and preset target air speed,regulating the air inlet amount of the air return opening, and controlling the air speed of the air outlet till the real-time air speed of the air outlet is equal to the preset target air speed. The device and method and the control cabinet are mainly used for testing the cabinet type fan.

Description

technical field [0001] The application belongs to the technical field of cabinet-type unit testing, and in particular relates to a cabinet-type unit testing device, method and control cabinet. Background technique [0002] Fan coil units are referred to as fan coil units for short. They are composed of fans, coils and filters. As the terminal device of the air-conditioning system, they are scattered and installed in each air-conditioned room, and can process the air independently. [0003] Large-scale central air-conditioning systems usually use large combined cabinet fan coil units. According to transportation requirements, large combined cabinet fan coil units need to be produced in functional sections. Usually, they are divided into combined cabinet fan sections and combined cabinet coil sections for separate production. [0004] In order to test whether the fan section of a certain type of combined cabinet meets the expected demand indicators, it is necessary to conduct ...
