Overview

The Rickard range of Thermo-Disc VAV ceiling diffusers help to provide an indoor environment that maintains a consistent and comfortable temperature. Diffusers only allow the required volume of hot or cold air to enter the conditioned space according to the diffuser set point. It is mechanically controlled and thermally powered which means it is easy to install and requires no external wiring or power supply.

Features and Benefits

Design

Air volume control is achieved through the vertical up and down movement of the control disc within the diffuser. They are available in 495 and 595mm square overall sizes and 150 to 300mm duct neck sizes. They come in square to square and square to round diffuser styles. Their unique design allows them to have a flush to the ceiling clean look.

Energy Efficient

Reduces the energy consumption of a building by lowering the demand on the air handling system.

Smart Sensors

Each unit contains its own in-built temperature sensing and volume control mechanism. This system will provide the occupant with control over their specific environment (temperature set point adjustable from 19ºC to 24ºC).

Testing

Methods of testing the performance of air outlets and air inlets. ANSI/ASHRAE Standard 70-2006 (RA 2011).

Specification

Construction

Rickard Thermo-disc Diffusers are made from sheet steel and finished in a chip resistant epoxy powder coating. They come in matte white as standard but can also be ordered in colours to suit the architectural requirements. All internal components are made from non-metallic material and are moulded in fire retardant Makrolon glass reinforced plastic.

Typical Applications

Can be used for single diffuser, single room applications through to large open areas with multiple diffusers on multi levels.

Control

Air volume control is achieved through the vertical up and down movement of the control disc within the diffuser. This increases or decreases the aperture size which allows either more or less conditioned air to enter the space. The position of the control disc is varied by means of a wax filled thermal element which responds to changes in sensed room temperature. With a rise or fall in sensed temperature the wax extends or retracts the plunger, causing the mechanism to move the control disc to match the air volume requirements of the space served by the diffuser.
