How do you install AHU system?

How do you install AHU system?

Shift the Air Handling Units to the place of installation in safe manner using fork lift/crane as applicable. Ensure that the correct AHU is shifted to the place of installation. Air inlet, outlet, fresh air connection and chilled water connection orientation are as per approved drawings.

What is the working principle of 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). Where hygienic needs for air quality are lower, the air from the rooms can be re-circulated for energy saving purposes.

What are the parts of AHU?

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 is AHU in construction?

An air handling unit (AHU) is a machine that conditions (i.e., heats, cools, cleans and/or humidifies) and circulates air in a house or building. AHUs are components of complete heating, ventilation, and air conditioning (HVAC) systems.

How many types of AHU 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 is AHU PDF?

Air handling unit (AHU) is one of the most important equipments in HVAC (heating, ventilation, and air-conditioning) system particularly in large-scale buildings for providing both heating and cooling for multiple zones.

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 motor is used in AHU?

The Integral AC Induction motor is the standard option for Solution Air Handling Units. It is the dominant motor technol- ogy in use today, representing more than 90 percent of installed motor capacity. The AC induction motor is a rotating machine that converts electrical power into mechanical power.

Where should AHU be placed in building?

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.

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.

What is the capacity of Ahu?

Yes Aluminium Air Handling Unit (AHU), Capacity: 2 Ton To 100 Ton
