Difference Between AHU and RTU

There are no differences between an AHU and an RTU except for the fact that an RTU is placed on the rooftop. ... The AHU consists of components such as heating elements, cooling elements, blower or fan, filters, mixing chambers, vibration isolators, humidifiers, heat recovery devices and controls.

What is a 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.

What is difference between AHU and FCU?

AHUs are usually connected to a central HVAC system whereas an FCU can function or be installed itself. Because of this, it is often the AHU that is used to ventilate an entire building whereas FCUs are used in smaller and often local spaces only.

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 ahu in HVAC system?

An Air Handling Unit (AHU) is used to re-condition and circulate air as part of a heating, ventilating and air-conditioning system. ... AHUs connect to ductwork that distributes the conditioned air through the building and returns it to the AHU.

What is RTU stand for?

RTU is an an acronym for Remote Terminal Unit. An RTU is an electronic device that is controlled by a microprocessor. The device interfaces with physical objects to a Distributed Control System (DCS) or Supervisory Control and Data Aqusition (SCADA) system by transmitting telemetry data to the system.

What is RTU system?

RTU stands for Remote Terminal Unit, sometimes also called Remote Telemetry Unit or Remote Telecontrol Unit. A RTU is a microprocessor based device that monitors and controls field devices, that then connects to plant control or SCADA (supervisory control and data acquisition) systems.

What does CU mean in HVAC?

CU stands for Condensing Unit (HVAC)

Why does Ahu trip?

Re: AHU tripping on the control panel

Overload devices goes weak with time, causing them to trip at lower currents than they are adjusted to and marked for. Electrical cables and terminations looses continuity with old age. Electrical motors get worn with age and change their characteristics.

What is CSU in HVAC?

Ceiling Suspended AHU (CSU)

How many types of Ahu filters are there?

The Three Types of Air Filters.

How does 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).

How do you calculate Ahu cfm?

Start with the total volume of air (in cubic feet), divide by the exchange rate (how quickly you want to replace the air), and the result is the total CFM you need for your system.
