Frequently Asked Questions

1. What is a thermal rotary wheel?

A rotary thermal wheel, also known as a rotary heat exchanger or rotary heat wheel, is a device used in HVAC (Heating, Ventilation, and Air Conditioning) air handling unit systems to recover heat and improve energy efficiency.

2. How does a rotary wheel work in an air handling unit?

The rotary thermal wheel in an integral part of a Blauair air handling unit and sits between the supply and extract EC fans inside the AHU. It consists of a cylindrical wheel made of a material with a high thermal conductivity, in this case, aluminium. The wheel is filled with a matrix of small passages or channels that allow air to flow through.

The wheel rotates slowly (typically 10-20 RPM) between two airstreams: one exhaust air stream and one supply air stream.

Exhaust Air Stream: This is the air being expelled from the building, which may be warm and humid.

Supply Air Stream: This is the fresh air being drawn into the building, which may be cooler and drier.

Heat Exchange Process: As the wheel rotates, it absorbs heat and moisture from the exhaust air stream and transfers them to the supply air stream. This process can be described in two phases:

Heating Phase: The portion of the wheel exposed to the exhaust air stream absorbs heat and moisture.

Cooling Phase: As the wheel rotates, this heated section moves into the supply air stream, where it releases the heat and moisture into the cooler incoming air.

3. What is an air handling unit?

An Air Handling Unit (AHU) is a device used to regulate and circulate air as part of a heating, ventilating, and air-conditioning (HVAC) system. It typically includes components such as a heat recovery core, blowers, heating and cooling elements, filters, dampers, and sound attenuators to ensure optimal indoor air quality and comfort.

4. How does an air handling unit work?

An Air Handling Unit works by drawing in outside air, filtering it, and then heating or cooling it as necessary before distributing it throughout a building. The AHU can also include humidifiers or dehumidifiers to control the humidity levels, ensuring a comfortable and healthy indoor environment.

5. What are the key components of an air handling unit?

Key components of an Air Handling Unit include:

  • Blowers: Move air through the system.
  • Heat Recovery Unit: To recycle heat from extracted air.
  • Filters: Remove contaminants from the air.
  • Heating and Cooling Coils: Adjust the air temperature.
  • Dampers: Regulate airflow and pressure.
  • Humidifiers/Dehumidifiers: Control humidity levels.

6. What are the benefits of using an air handling unit?

Using an Air Handling Unit offers several benefits: Improved Air Quality: Filters out dust, pollen, and other pollutants. Energy Efficiency: Modern AHUs are designed to use energy efficiently. Comfort Control: Maintains consistent indoor temperature and humidity levels. Flexibility: Can be customized to meet specific building requirements.

7. How to maintain an air handling unit?

Maintaining an Air Handling Unit involves regular inspections and cleaning of filters, coils, and blower components. It's also important to check for and seal any leaks, ensure proper lubrication of moving parts, and inspect the control systems to ensure they are functioning correctly.

8. What types of air handling units are available?

There are several types of Air Handling Units, including:

  • Packaged Units: All components are housed in a single unit.
  • Modular Units: Components can be customized and assembled on-site.
  • Rooftop Units: Installed on the roof, typically used in commercial buildings.
  • Horizontal Units: Designed to fit in tight spaces with horizontal airflow.
