Introduction - VAV Diffusers

Products

VAV Diffusers

Our next generation of Rickard VAV Diffusers not only provide occupants with optimised thermal comfort, they are also easier to install, and include more features and functionality. These auto zoning diffusers can operate through a BMS or Rickard standalone software, and reduce power consumption by lowering demand on the air handling system.

The Drive for Comfort and Energy Efficiency

There is a growing need for products that help create comfortable indoor spaces while maintaining a healthy and productive working environment. At the same time, new government policies and the dramatic increase in energy costs have created greater demand for products and systems that utilize energy efficient technologies. These new demands are now being driven by architects, engineers and developers to create buildings that offer both the optimal working conditions while saving energy consumption and reducing greenhouse gas emissions.

The RICKARD range of Variable Air Volume (VAV) diffusers helps meet these demands and is a cost effective system that is simple to operate and very reliable.

The Drive for Comfort and Energy Efficiency

Highly Effective Design

Our next generation of Rickard VAV Diffusers provides occupants with optimised thermal comfort and is easier to install. These auto zoning diffusers can operate through a BMS or Rickard standalone software, and reduce power consumption by lowering demand on the air handling system. The system can accommodate a single Rickard VAV diffuser or can be expanded to control thousands of networked VAV diffusers. Since each Rickard diffuser is self-modulating, smaller zones can be easily controlled, making them more comfortable for occupants.

This VAV design, combined with smart commissioning software, enables substantial benefits:

Better Thermal Comfort & Air Quality
Enables Capital Expense Savings
Reduces Energy Consumption
Configurable and Flexible VAV System
Streamlined Plug-n-Play Connectivity
Temperature and Occupancy Sensing Standard with Every Diffuser

Better Occupant Comfort and Air Quality

Rickard VAV diffusers help to provide a well ventilated indoor environment that maintains a consistent and comfortable temperature. They eliminate undesirable thermal conditions that can have an effect on output, accuracy and productivity.

Rickard diffusers only allow the required amount of conditioned air to enter the space. This air volume is determined by the temperature in the space and the set-point on the diffuser’s in-built temperature sensor or wall thermostat. Each individual temperature set-point can be easily adjusted for the occupant, giving personalised comfort control over the environment.

Rickard VAV diffusers provide excellent supply air distribution compared to traditional VAV box systems. By changing the diffuser’s exit geometry, we maintain coanda, air velocity and throw at both minimal and maximum volume. This prevents cold air from being dumped and ensures better air mixing, Air Change Effectiveness (ACE), and consequently, greater thermal comfort (ADPI).

An Energy Saving Solution

A key benefit of Rickard VAV diffusers is their ability to reduce the energy consumption of a building by reducing the demand on the air handling system. This is achieved by allowing only the required volume of hot or cold air to enter a conditioned space according to the set point. If the required air volume reduces, the diffuser’s aperture size also reduces which creates additional pressure in the ductwork. The accumulated pressure signals to the air conditioning system to slow down which in turn saves fan energy. When the required air volume increases, the diffuser’s aperture opens allowing more conditioned air to enter the space.

The incentive for building owners and tenants to have energy efficient rental spaces has never been higher. Rickard VAV diffusers can also help achieve Green Building Credits for Building Management, Indoor Environmental Quality and Energy Efficiency.

Aperture fully opened to allow 100% of air flow to enter space

Aperture almost fully closed to allow only 10% of air flow to enter space

Rickard VAV diffusers are available as:

System controlled, electronically
powered models.

Standalone, mechanically
controlled models

Each VAV diffuser model is available in various configurations which are suitable for numerous applications or mounting positions. The range comes in square, linear slot and bulkhead models.
