Abstract:

The study suggests an automatic temperature control system for more than one industrial air conditioner since industrial equipment is much more complicated than household one and often requires working out individual projects. The mathematical modelling of a water cooler of an industrial air conditioner is based on transfer functions that allow an accurate description of the object of control. This mathematical model reflects the real nature of changes in air parameters and can be used in the development of other temperature control devices. The devised scheme simulates the behaviour of control systems for industrial air conditioners. The scheme of the control system is implemented in the Simulink package, MATLAB. It includes two air conditioners and operates in three modes that are determined by temperature ranges. The research reveals the operational features of the automatic control system for two industrial air conditioners, reflecting the nature of changes in the air temperature and experimental values of the system operation time. The versatile nature of the new system distinguishes it among other automatic control systems and makes it valuable for further research in this area. The possibility of adjustment to air conditioning peculiarities allows creating an improved control system that would resolve the problem and ensure an effective control of air conditioners. The research findings can be used in further individual projects of air conditioning of industrial buildings, which is likely to provide high-quality automatic air temperature control modes.
