Overview
Rickard linear slot diffusers provide an effective means of distributing conditioned air into the perimeter zones of a building where the temperature control requirements are the most demanding. The slim, attractive shape of the diffuser ensures that its subtle design works with most architectural styles. At the same time its superior aerodynamic design ensures that the air distribution creates no drafts, is quiet and highly efficient.

Features and Benefits
Design
A linear slot diffuser must be connected to a wall thermostat (temperature sensor) for it to perform as a master diffuser. The diffuser can then operate with one or more slave diffusers, or as a standalone system. Air volume control is achieved with the opening and closing of vanes driven by an electric actuator. This increases or decreases the aperture size which varies the volume of conditioned air to enter the occupied space.
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 by opening and closing of the diffusers aperture which varies the volume of conditioned air to enter the occupied space. The aperture is driven by a 12V DC electric actuator which receives a signal from a Rickard diffuser’s master controller. 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. Matt pen white is but specific colours can be ordered to suit the architectural requirements*. All internal components of nonmetallic 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.
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
Methods of testing the performance of air outlets and air inlets. ANSI/ASHRAE Standard 70-2006 (RA 2011).
