At present,the level of industrial automation has become an important indicator of the modernization level of all walks of life.Due to the needs of human production and life,the application of HVAC systems has been continuously expanded and has become an essential basic supporting facility for large indoor places.
HVAC is abbreviated as HVAC.It mainly maintains the comfort of the indoor environment by controlling boilers,refrigerators,water pumps,fans,air conditioning units,etc.The cold and heat source refrigeration monitoring is the core of the entire air conditioning system,and PID control is an indispensable part of it.
PID control is well known in the automation industry and is also called PID regulation.It consists of a proportional unit(P),an integral unit(I)and a differential unit(D).It is widely used in the field of automation control because of its simplicity and ease of understanding.Choosing appropriate PID parameters is critical to the stable operation of the air conditioning system.
Unimat PLC is favored by many temperature control engineering projects for its excellent PID control function.
Unimat PLC supports 32-way incremental PID,32-way self-tuning PID,and 32-way fuzzy temperature control.It can be used with TTC temperature curve control,VC valve control and other instructions to easily achieve various complex control requirements.In addition,the special digital temperature and humidity module of Unimat PLC can accurately measure temperature and humidity within a range of 200 meters,and the collected temperature and humidity valueshave no errors and the cost is very low.It has its own communication port,supports remote functions,and can also be used as a remote IO module.
What are the advantages of using PLC in HVAC systems?
PLC is fast,flexible and reliable.It is easy to replace,has low energy consumption,and helps with diagnosis.Automation of various components,including counters,timers and comparators.It makes the work of HVAC technicians easier.The simple operation interface simplifies complex diagnosis and unifies it in one environment.
Improved accuracy and reliability are two other benefits of programmable logic controllers.They give HVAC technicians greater freedom and control,allowing them to better control the way they work without negatively affecting system performance or efficiency.
Moreover,the new generation of Unimat Ethernet cloud HMI is the icing on the cake for the project.This series of HMI supports the Unimat cloud platform and can be accessed and controlled through the cloud or mobile phone.Even if you leave the project site,you can log in to your mobile phone directly to view the status of the monitoring project anytime and anywhere.In abnormal conditions,it can also send you alarm information in time through email,mobile APP and SMS,so you can relax and worry-free!
In addition,with the continuous development of the Internet of Things(IoT)and artificial intelligence(AI),these technologies will gradually be integrated into the HVAC field.By combining PLC with smart sensors,cloud platforms and machine learning algorithms,a more intelligent,adaptive and predictive HVAC system can be achieved.So far,Unimat PLC&HMI has also realized AI intelligent control in the HVAC field,which has brought great convenience to customers in subsequent use.
The development of automation is inseparable from the continuous innovation of science and technology.Unimat will continue to forge ahead and provide better products and services for social production and life!
