Side-blowing air-conditioner control method

Abstract

This is a computer control method use to side-blown air conditioner, which is mainly used to the chemical fiber industry. It contains following control steps: Use the sub-system to collect data in time, on the computer to judge this data whether or not accord with the mathermatical model, to judge the result parameters of temperature, wet, air press are whether or not in the command interval, if the result parameters do not accord with the command, the computer can control the enthalpy value of these parameters and to do the most optimize save energy adjustment, to calculate the output value of the mathematic model of these parameters, then the output value adjust the valve gate, control the temperature, wet, and air-pressure. As this method use the enthalpy value to control the side-blown system, so it can overcome the defect of the wet and temperature to produce 'vibration', the working condition of the machines are steady, and the temperature, wet, and pressure values can keep high accurate.

Description

technical field [0001] The invention relates to a side blowing air conditioner control method in the chemical fiber industry, which is mainly applicable to the computer control system of the side blowing air conditioner in the production of long and short yarns in the chemical fiber industry. Background technique [0002] Since the side blowing section in the production of filament and short yarn in the chemical fiber industry is the key processing section, the temperature, humidity, and air pressure control accuracy of the air supply are required to be high. At present, most of the German LTG products are used in this industry, and this type of products adopts conventional instrument control methods. The so-called conventional instrument control method refers to the use of conventional control instruments to detect temperature, humidity, ie relative humidity, and wind pressure. Then you can only adjust the single variable one by one. If the temperature is too low, just adj...

Problems solved by technology

As well as supporting automatic control equipment, which need to be imported from foreign countries, the price is expensive, and it is not easy to promote on a large scale

There are also a small number of computer system control methods, and single-variable adjustment is still used in the mathematical model, and the two variables of humidity and temperature in conventional instrument control cannot be decoupled, resulting in "oscillation", which makes the control effect poor and difficult to achieve high.
