Air conditioner control system

Abstract

The invention discloses an air conditioner control system, and relates to the field of clean rooms. According to the technical scheme, the air conditioner control system comprises an air supply air conditioner box, a detection device and an industrial personal computer, wherein the air supply air conditioner box comprises a primary-effect filter section, an air supply power section and a medium-effect filter section which are sequentially arranged from the air inlet side to the air outlet side, the detection device comprises a primary-effect differential pressure sensor, a fan differential pressure sensor and a middle-effect differential pressure sensor, wherein the primary-effect differential pressure sensor is used for detecting the differential pressure of the two ends of the primary-filter section, the fan differential pressure sensor is used for detecting the differential pressure of the two ends of the air supply power section, the middle-effect differential pressure sensor is used for detecting the differential pressure of the two ends of the middle-effect filter section, and the industrial personal computer is used for outputting a control signal for starting an alarm on the basis of output signals of the primary-effect differential pressure sensor, the fan differential pressure sensor and the middle-effect differential pressure sensor. The air conditioner control system has the effects of facilitating maintenance personnel to know the condition of the interior of the air conditioner box and saving the time length of detection.

Description

technical field [0001] The present invention relates to the field of clean room, more specifically it relates to an air conditioner control system. Background technique [0002] At present, the Chinese patent with the publication number CN106051966A discloses an automatic fresh air control system for clean rooms, which includes an air-conditioning plenum, an air duct, a regulating valve installed on the air duct, a differential pressure sensor I, a differential pressure sensor II, and a control system. One end of the air duct is connected to the air-conditioning static pressure box, and the other end of the air duct is placed in a clean room. The differential pressure sensor I is installed in the air-conditioning static pressure box, and the differential pressure sensor I is driven by the control system and the air-conditioning static pressure box. The modules are linked; the differential pressure sensor II is installed in the clean room, and the differential pressure sensor...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the air-conditioning control system is similar to the above-mentioned air-conditioning control system, which controls the opening degree of the regulating valve by detecting the pressure difference between the clean room and the air-conditioning box, thereby avoiding excessive pressure difference in the clean room; Filter the fresh air, so there will be a pressure difference between the two ends of the filter in the air-conditioning box; and when the pressure difference in the clean room is too small, maintenance personnel often need to spend a long time checking each position of the air-conditioning box
