Identify where hvac controls are required: main mechanical room, secondary equipment room, and rooftops, to manage chillers, boilers, heat exchangers, pumps, and air handling units for temperature and humidity.
Learn how HVAC control uses sensors and devices to start, stop, and regulate cooling, collect temperature and humidity data, define comfort measures, and process data to save energy.
Explore how humidity sensors measure moisture and control indoor humidity, and examine pressure and indoor air quality sensors for building energy efficiency and healthy air, with AQI.
The central air conditioning system uses a compressor to pressurize refrigerant, which releases heat in the condenser and absorbs heat in the evaporator to deliver chilled water for cooling.
Explore chiller control system, including 32 t2 temperature sensor for water supply, interlocked control wells with one inlet and two outlets, and a variable frequency drive that controls cooling.
Explore how AHU cooling and heating coils use temperature sensors and interlocked water flow with control valves to switch between cooling and heating.
this course is about control systems .in this course you can learn about HVAC controls. By using HVAC control system we make our system more Energy Efficient.
Most of Energy in Building was Consumed By HVAC devices like chiller use large amount of energy, similarly fan coil units, Air Handlin units and other HVAC Devices uses large amount of Energy
For increasing energy efficiency of building HVAC control is very important because control system have a lot of benefits to maintain thermal comfort conditions HV AC control work very efficiently similarly it also help us to control indoor air quality and as we discussed earlier that a lot of energy is saved so over operation like a plant operation are very efficient
this course is very important because in this course you can learn a lot of things about HV AC controls and their application in real life we can also discuss about about the control devices, sensors ,controllers and all other Devices. By using energy efficient system we save a lot of over money the initial cost is high but it and we pay back within some years . So energy efficiency is very important nowadays
course contents.
Fundamentals of HVAC Controls
In fundamentals of control we can discuss about the automatic control about the HV AC system and the parameters of control that we can control in HVAC systems like temperature ,humidity ,ventilation, pressures etc we can also discuss about control strategies and where control is required.
Control Basics
In control basis we can discuss about what is control the element of control, theory about control like open loop control and close loop control systems, so now we can also discuss about a type of control like directing system ,electric systems, similarly Pneumatic Systems, microprocessor system and mixed system
SENSORS
in this section you can learn about sensors and there different types and working principles
