Embodiment Construction

[0040] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0041]Since the meteorological parameters outside the workshop vary greatly, the dew point automatic control energy-saving strategy of the textile air-conditioning system in the present invention is divided into three control modes: winter, transitional season and summer according to the meteorological parameters outside the workshop:

[0042] When the PLC control system is powered on, each device of the air-conditioning system performs an initial assignment, fresh air temperature and humidity sensor 9, mixing point temperature and humidity sensor 10, water temperature sensor 11 in the return pool of the spray room, dew point temperature and humidity sensor 12, and workshop temperature and humidity sensor 13 , The process return air temperature and humidity sensor 14 starts to return the parameters collected in real time to the PLC control sys...

Abstract

The invention discloses a textile workshop air conditioner system PLC automatic control method. The method comprises the steps that firstly, a PLC control system is initialized; various parameters ofa textile workshop are collected into the PLC control system; and finally, the PLC control system carries out analysis calculation according to the collected data, finally, an air conditioner system is controlled to run, and the problems that an existing textile air conditioner automatic control system is poor in control strategy control precision, and adjusting of an air conditioner automatic control system for the workshop temperature and humidity is delayed are solved.

Description

technical field [0001] The invention belongs to the energy-saving technical field of textile air-conditioning systems, and in particular relates to a PLC automatic control method for an air-conditioning system in a textile workshop. Background technique [0002] At present, the PLC automatic control system of air conditioners in textile factories lags behind the adjustment of fans and water pumps, and the control accuracy is not high, which leads to high energy consumption of textile air conditioners. Therefore, it is imperative to study the automatic control energy-saving strategy of textile air-conditioning system. Contents of the invention [0003] The purpose of the present invention is to provide a PLC automatic control method for the air-conditioning system in textile workshops, which solves the problem that the control strategy of the existing textile air-conditioning automatic control system has insufficient control precision and the air-conditioning automatic cont...
