What is ceiling suspended unit?
Suspended air conditioning units are fitted to the ceiling to provide fast and effective cooling in large spaces. Suspended air conditioner units, sometimes referred to as ceiling suspended air con units, fit directly onto the ceiling and feature swing louvres which effectively distribute cool air around a large space.
What are the main functions of an Air Handling Unit AHU )? What are the main components of an 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.
How many types of Ahus are there?
There are three basic types of an air handling unit. When trying to decide on the purchase of custom air products, Houston residents should choose from the following: Terminal units: Include only an air filter, coil and blower. Simple terminal units are often called fan coil units or blower coils.
What are ceiling units?
It differs from other types of air conditioners, primarily by the way it is mounted. As the name would suggest, ceiling cassette units are mounted in the ceiling and are best suited to the ‘floating’ or suspended ceiling, where there is sufficient space to accommodate it.
What is ceiling mounted air conditioner?
Unlike ceiling cassette’ units which are placed within a false ceiling, under ceiling AC units are usually mounted near a wall and just below ceiling height. Whilst they are not considered as aesthetically pleasing as ceiling cassettes, they are a far more powerful option in terms of air flow.
Why heating coil is used in AHU?
It is also possible that a secondary heating coil in the AHU is located in the downstream side of the supply fan or cooling coil. The purpose of this secondary heating coil is to add additional heat to the air stream in cold climate zones, or climate zones where de- humidification is required.
Which blower is used in AHU?
Blower/fan Air handlers typically employ a large squirrel cage blower driven by an AC induction electric motor to move the air. The blower may operate at a single speed, offer a variety of set speeds, or be driven by a variable-frequency drive to allow a wide range of air flow rates.
How does the AHU work?
The AHU is normally a large metal box which connects to the ductwork that channels conditioned air throughout a building and returns it back to the AHU. AHU’s supply fresh air to the room. The units take air from the outside, filter it and recondition it (cooled by a cooling coil or heated by a heating coil).
Why choose an ahu – air handling unit?
From one of Britain’s leading manufacturers of AHU – Air Handling Units, AirCraft Air Handling of Stafford have designed the In-Ceiling Air Handling Unit to provide high performance with low noise break out.
What is the in-ceiling air handling unit made of?
Manufactured from high quality aluminium profile, the In-Ceiling Air Handling Unit is supplied fully assembled but can be provided flat-packed where accessibility is restricted.
What are the advantages of One ahu per floor?
Advantages of one AHU per floor: Redundancy (if a fan, motor, coil, or damper fail only one floor is adversely affected) The size of the AHU would be smaller on each floor. Smaller horsepower fans often haven better acoustical qualities. Different voltages may be available for smaller AHUs.
How does a dual flows Ahu work?
The dual flows AHUs know how to work according to different working systems. Total recycling : no fresh air is brought, air traitment is working as closed circuit, only with the ambient air, Partial rcycling : part of the air treated is rejected and replaced by fresh air. 100\% Fresh air : the air intake flow equals to the air supplied.
