The Intelligent Central Air Conditioning Training System Design

With the development of society, air conditioning from scratch, from luxury to be presentbefore the necessities of life, and gradually play an increasingly important role, and central airconditioning also entered the major shopping malls, supermarkets, office buildings and otherpublic place in the future, will spread to the residents of the home. People’s living standardsimprove, the stability of air conditioning, air cleanliness, comfort and other senses also beenfurther demand, resulting in air conditioning air conditioning and temperature and humiditycontrol technology presents more complexity and diversity. Involved in teaching expertise andcontrol technology is also increasing, which requires central air conditioning maintenance andmanagement staff must have a more comprehensive technical expertise, but also for teachingin the central air-conditioning, professional maintenance staff training production linemechanic colleges put forward higher requirements.This thesis is based on the current vocational training obsolete equipment central airconditioning, single, reaching less than comprehensive training purposes, in the context of thedevelopment of the times and expanded. Paper is designed to ensure the integrity andauthenticity of central air conditioning system under the premise were intelligent, centralized,miniaturization control, reaching only control and energy saving requirements, teachingequipment and teaching mode from the start, instead of better teaching methods for studentsto achieve a more comprehensive and systematic study.This thesis mainly includes air temperature control and frequency control analysis,control system design of the structure and equipment selection, console communications andcircuit design, training to carry out the task and experimental analysis of several parts. ThePLC, touch screen, inverter, sensors and other automatic control technology and refrigerationmaintenance technology integration, through design, installation and commissioning to meetteaching requirements. This system is designed to completely get rid of the past, studentstraining as a pure simulation mode of teaching, to provide students with a morecomprehensive system of training platform for large central air-conditioning maintenance,debugging also produced a guiding significance. Same time, through multidisciplinarylearning, for the existing social, business skills required of the compound talents also played apositive role model.
