Filter, air cabinet unit and air conditioning unit

Abstract

The invention discloses a filter, an air cabinet unit and an air conditioning unit. The filter comprises a frame, a filter screen, a driving mechanism and a detection unit, wherein the filter screen is rotationally arranged in the frame, the driving mechanism is used for driving the filter screen to rotate, the driving mechanism comprises a driving motor; the driving motor is in transmission connection with the filter screen, the filter further comprises a controller, and the detection unit is connected with the controller; the detection unit comprises a differential pressure alarm device, andwhen the differential pressure value exceeds a first preset value, the driving mechanism drives the filter screen to rotate by 180 degrees; the detection unit further comprises a carbon dioxide monitoring device, and when the carbon dioxide monitoring device detects that the concentration of carbon dioxide is lower than a second preset value, the filter screen rotates to be parallel to the airflow direction. Compared with the prior art, when air does not need to be filtered, the air does not pass through the filter screen, and when too much dust is accumulated on the filter screen to affect the filtering efficiency, the filter screen can be rotated by 180 degrees to blow away dust by air, and the problem that in the prior art, the air cabinet unit is high in excessive energy consumption is solved.

Description

technical field [0001] The invention relates to the technical field of air treatment equipment, in particular to a novel energy-saving filter, wind cabinet unit and air conditioner unit. Background technique [0002] As a common air treatment equipment, the wind cabinet unit is used to filter and pressurize the air. Generally, there is a filter inside the wind cabinet unit to filter the air. However, it is more mechanical in filtering the air, that is, filtering No matter whether the air needs to be filtered or not, it is always in working condition, and it cannot be adjusted according to the air quality. For example, when the concentration of carbon dioxide in the air is low, the air does not need to pass through the filter, and the filter often Opening causes pressure loss, and the power consumption of the wind cabinet unit is proportional to the internal pressure loss of the unit, that is, the higher the internal pressure loss, the greater the power consumption of the win...
