HVAC System and Equipment's

About this course

In this course you can learn about different systems and Equipment related to HVAC . there are different types  of HVAC systems in this course we can discuss all of them The basic components or equipment of an HVAC system that delivers conditioned air to satisfy thermal comfort of space and occupants and the achieve the indoor air quality are listed below .so we discuss all Equipment used in HVAC system there working principeAll-air systemsThe thermal energy transfer medium through the building delivery systems is air. All-air systems can be sub-classified based on the zone as single zone and multizone, airflow rate for each zone as constant air volume and variable air volume, terminal reheat, and dual ductSingle zoneMulti-zoneTerminal reheatDual ductVariable air volumeAll-water systemsAn all-water system, heated and cooled water is distributed from a central system to conditioned spaces . This type of system is relatively small compared to other types because the use of pipes as distribution containers and the water has higher heat capacity and density than air, which requires the lower volume to transfer heat.Fan-coil unitsAir-water systemsFan-coil unitswe discuss following EquipmentMixed-air plenum and outdoor air controlAir filterSupply fanAir handling unitssome DevicesExhaust or relief fans and an air outletOutdoor air intakeDuctsTerminal devicesReturn air systemHeating and cooling coilsSelf-contained heating or cooling unitCooling towerair cooled chillersabsorption chillerscentrifugal chillersControlWater chillerHumidification dehumidification eq
