Overview

The square electronic diffusers feature a modern flush to the ceiling look and are available in 3 distinctive styles: square to square, square to round and square to swirl. Square to square and square to round diffusers produce low noise levels and are designed for general building zones where a uniform radial air distribution pattern is preferred. The square to swirl diffuser is more efficient at generating good mixing between supply and room air.

Features and Benefits

Design

Air volume control is achieved through the vertical up and down movement of the central control disc mechanism within the diffuser. This increases or decreases the aperture size which varies the volume of conditioned air to enter the occupied space. Available in neck sizes from 150 to 350mm diameters and tile sizes of 495 x 495mm and 595 x 595mm (see range dimension diagrams for more detail).

System Flexibility

Diffusers can be individually controlled by either a wall thermostat or the on-board master controller that sends its signal back to the BMS. The entire system is then monitored and changes can be made via a computer either on-site or remotely using the Rickard stand-alone software or a BMS. These intelligent VAV Diffusers operate on a low pressure ductwork design, making them highly energy efficient, but the pressure in the duct work must be controlled for optimal performance. For new installations duct design that achieves static regain is highly recommended. If retrofitting to existing ducting, a relief ring can be fitted to the diffuser to release air pressure when the diffusers close.

Air Control

Air volume control is achieved with the opening and closing of the diffusers aperture which varies the volume of conditioned air to enter the occupied space. The system is supplied with Rickard MLM software that is used for commissioning, setting diffuser parameters, monitoring the network, logging diffuser activity and converting slave diffusers to master diffusers, all from below the ceiling via a computer. The system can also be controlled through the building’s BMS.

Typical Applications

The Rickard Electronic diffuser system can be as simple as one diffuser in a single room or scaled up to work within large open areas with multiple diffusers on multi levels of a building. 60 diffusers can be accommodated on a single Rickard Master Communication Unit (MCU) and multiple MCU’s can be connected to a BMS.

Specification

Construction

Diffusers are made from sheet steel and finished in a chip resistant epoxy powder coating. Matte white standard but specific colours can be ordered to suit the architectural requirements. All internal components of non metallic construction are moulded in fire retardant Makrolon glass reinforced plastic.

Mechanism

Air volume control is achieved through the opening and closing of the air outlet mechanism within the diffuser. This mechanism is driven by an electric actuator and allows more or less air to enter the occupied space. The aperture shall be driven by a 12V DC electric actuator which receives a signal from a Rickard diffuser’s master controller.

Power Supply Unit

The PSU is able to power up to 15 Electronic VAV Diffusers. It requires an input of 85-265 Vac and an output of 36 Vdc regulated at 1.2 Amps. Maximum operating temperature is 0°C to +50°C. The unit has an overall power consumption of 50 Watts. It features industry standard DIN rail mounting.

Testing
