What is the function of air handling unit AHU?
The air handling unit (AHU) is the heart of central air conditioning. It collects outside air and room air, removes dust and other particles from the collected air, adjusts the temperature and humidity and then supplies comfortable and refreshing air-conditioned air into the rooms through ducts.
What is difference between AHU and HVAC?
AHU, which is Air Handling Unit is an appliance used to circulate air. HVAC is Heating, Ventilating and Air Conditioning system. HVAC is the central unit to which AHU is connected. AHU is only a part of HVAC and as such there is hardly any difference between then two.
What are the components of air handling unit?
The AHU is a large metal box containing separate ventilators for supply and exhaust, heating coil, cooling coil, heating/cooling recovery system, air filter racks or chambers, sound attenuators, mixing chamber, and dampers.
What are the parts of AHU?
Can FCU work without AHU?
Fan Coil Unit (FCU) An FCU is not as complex or extensive as an AHU. It’s a singular system that can operate on its own to circulate air in an area without ductwork.
What are the principles of air handling unit (AHU)?
Principles of Air Handling Unit (AHU) Air should be distributed in the room, so that, the required temperature, humidity and air velocity are maintained in the occupied zone of about 1.8 m above the floor. Air stratification, temperature difference, dead pockets, high drafts, stagnation layers and convection currents must be avoided.
What is a single duct AHU air handler?
A “Single Duct” AHU variation • The exhaust air damper is not in this air handler; the building air is exhausted elsewhere, but the basic mixed air and other functions are unchanged. Air Handler Components
What are the components of an air handler?
Air Handler Components Temperature Sensor: • Temperature sensors are used for measurement of temperatur of a Room, Air Duct, Hot /Cold Water, Outside Air etc. • Models are available with PT1000, NTC20K, BALCO500 sensing elements. LF20 : AIR DUCT TEMP. SENSOR (NTC 20k) T7412 : ROOM TEMP. SENSOR (PT1000/NTC 20k) T7413A : IMMERSION TEMP.
