What is AHU and FCU?
By Joe Hullebusch Blog March 5, 2019.
In simple terms, an air handling unit (AHU) is a component of an HVAC system that cools and distributes air into the space through a duct.
A fan coil unit (FCU) is a standalone system that circulates the existing air in a small space, but it can also be a part of an HVAC system..
What is CSU in HVAC?
Ceiling Suspended AHU (CSU)

How is VRF calculated?
Calculating Cooling LoadBtuh = CFM x 1.08 x (EAT – LAT)CFM = Btuh / 1.08 x (EAT – LAT)Q = U x A x TD.Q = Btu/Hour.U = The U-Factor is the reciprocal of the Resistance.A = Area (Ft2) of Building Component.TD = Temperature Difference.Q = A x SC x SCL.More items…•
How many types of VRF are there?
two different typesSystem types There are two different types of VRF systems: Air-cooled, where multiple compressors are connected to a refrigerant-piping loop.
What are the types of Ahu?
There are basically two types of air handling unit that are in used and they are the “Draw-Through” or “Blow-Through”. In the Draw-Through type, the fan pulls the air through the mixing box, filters and cooling coil before discharging it from the fan outlet to the space to be conditioned or to the ducting network.
What is the main function of Ahu?
An Air Handling Unit (AHU) is used to re-condition and circulate air as part of a heating, ventilating and air-conditioning system. The basic function of the AHU is to take in outside air, re-condition it and supply it as fresh air to a building.
What is VRF system?
The simplest explanation of VRF is to describe it as a large-scale ductless HVAC system that can perform at a high capacity. The specific design of a VRF system varies based on application. In general, VRF technology provides the ability for multiple indoor units or zones to operate on the same system.
What is Pahu in HVAC?
PAHU means Precision Air Handling Unit. HVAC meansHeating, ventilation, and air conditioning.
What is the principle of HVAC?
The V in HVAC, or ventilation, is the process of replacing or exchanging air within a space. This provides a better quality of air indoors and involves the removal of moisture, smoke, odors, heat, dust, airborne bacteria, carbon dioxide, and other gases as well as temperature control and oxygen replenishment.

Where do you put Ahu?
They are usually located in the basement, on the roof or on the floors of a building. AHU’s will serve a specified area or zone within a building such as the east side, or floors 1 – 10 or perhaps a single purpose such as just the buildings toilets. Therefore, it’s very common to find multiple AHU’s around a building.
How many types of Ahu filters are there?
The Three Types of Air Filters.
What is an ahu system?
An Air Handling Unit (AHU) is used to re-condition and circulate air as part of a heating, ventilating and air-conditioning system. An Air Handling Unit (AHU) is used to re-condition and circulate air as part of a heating, ventilating and air-conditioning system.
How many types of HVAC are there?
fourThere are four main types of HVAC systems. There are split systems, hybrid systems, duct-free systems, and packaged heating and air systems. Each of these types of HVAC units have pro’s and con’s, and knowing these factors can help you decide which is best for you.
How does Ahu work?
Air Handling unit or AHU is an assembly of air conditioning components (such as fans, cooling coils, filters, humidifiers and dampers) integrated into a self-contained package and installed as a single unit, which is connected to system of metal duct work that distributes the conditioned air.
Do air handling units have refrigerant?
Air handlers contain one of two cooling elements: chilled water or refrigerant. … First, the air returns from the space, passing back through a duct to the air handling unit. From here, the return air may move into a mixing box and blend with warmer outdoor air that is vented in.
What is RTU in HVAC?
A rooftop HVAC unit, or RTU, works very similarly to most indoor systems: They provide heating or cooling to an area by treating the air that passes through it and then circulating that air. In particular, a rooftop unit is an air handler – the part of the system that conditions the air and circulates it.
