Abstract

The invention discloses a ventilation system capable of achieving a constant air outlet state and a ventilation unit, and belongs to the technical field of ventilation systems. The ventilation system comprises a ventilation host, a fresh air inlet channel and a dirty air outlet channel are arranged on the two sides in the ventilation host respectively, draught fans are fixedly installed on the rear side in the fresh air inlet channel and the front side in the dirty air outlet channel respectively, a current detection unit which is used for detecting the current values of the draught fans and a control unit which is used for judging and adjusting the current values of the draught fans are further fixedly installed on one side of the ventilation host, and a plurality of filter screens are installed on the front side in the fresh air inlet channel at equal intervals through a lower filter screen installation frame and an upper filter screen installation frame and used for carrying out multiple filtering on impurities in fresh air. According to the ventilation system, the ventilation quantity of fresh air entering the plurality of filter screens in the channel is maintained through washing, the current values of the draught fans are detected and judged, then the power of the draught fans is adjusted to be constant, and finally the fresh air outlet quantity of the ventilation system is constant.

Description

technical field [0001] The invention belongs to the technical field of fresh air systems, and in particular relates to a fresh air system and a fresh air unit capable of realizing a constant air outlet state. Background technique [0002] The fresh air system is based on sending fresh air into the room with special equipment on one side of the closed room, and then exhausting it from the other side to the outside by special equipment. A "fresh air flow field" will be formed indoors to meet the needs of indoor fresh air ventilation. The implementation plan is: adopt high wind pressure, large flow fan, rely on mechanical force to send air from one side to the room, and use a specially designed exhaust fan to discharge to the outside from the other side to force the formation of a fresh air flow field in the system. While supplying air, the air entering the room is filtered, sterilized, sterilized, oxygenated, and preheated. [0003] In the existing fresh air system, due to th...
