1. VARIABLE AIR QUALITY STATION

CONAIRE's VAQs is an air measuring control damper that utilises rapid average pitot tube for airflow measurement and low leakage volume control damper for volume control. The VAQ series combines the functionality of an accurate airflow measuring station, low leak control damper with actuator, and an advanced application specific controller into one compact assembly.

Each VAQs station is factory calibrated and programmed with an exponential flow equation, where flow is proportional to signal received from pressure transducer to regulate the control damper to achieve desired demand.

Every VAQ Station comes standard with Honey-Comb patterned airflow straightener. Thus its whole assembly is self sufficient for accurate & reliable air-flow measurement. It also has differential pressure sensor, zero calibrated and factory programmed (for non linear exponential airflow calculation routine) to provide most accurate and reliable airflow measurement in ducts.

Each VAQ station is dynamically calibrated at our-state-of-the-art facility, thus ensuring accuracy in performance and enabling fabrication to site-specific customised sizes, thereby eliminating the need for any additional transition piece for installation. This means that every Conaire VAQ Station has an ease of installation built-in.

APPLICATIONS: OUTDOOR AIR

Outdoor Air application can be further classified as Single Space and Multiple Space DCV system.

• Single Space DCV system: the ventilation system delivers fresh outdoor air to a single space. This is a simple system and we can easily strategise demand controlled ventilation using an indoor air quality sensor installed at space & application specific control. In addition to this, free cooling control can be provided by supplying an optional sensor and controller.

• Multiple Space DCV system: here the ventilation system delivers fresh outdoor air to the air handler which mixes return air from several, individual, controlled spaces. Each individual controlled space needs to have a VAQ station installed with an indoor air quality sensor & application specific supply air control. The demand controlled ventilation can be strategised by using multiple space equation and at the same time air handler drive speed can be optimised. In addition to this, free cooling control can be provided by supplying an optional sensor and controller.

APPLICATIONS: SUPPLY AIR

For Supply Air, an air measuring control damper combined with an indoor air quality sensor & application specific control which varies the flow of air to each space maintaining the desired zone temperature.

2. VARIABLE AIR VOLUME TERMINAL

CONAIRE's VAV Terminal is an air measuring control damper, with individual space thermostat to vary the flow of air to each space, maintaining the desired set point temperature. It combines the functionality of an accurate airflow measuring rapid average pitot tube with an ultra low differential pressure sensor, a low leak control damper with actuator, and an advanced application specific controller, into one compact assembly.

Each VAV station is factory calibrated with exponential flow equation, where flow is proportional to signal received from pressure transducer to regulate the control damper to achieve desired demand. The unit modulates cold airflow from minimum to maximum setting, thereby achieving desired zone temperature. It provides cost effective temperature control.

Each VAV terminal is tested rigorously, thereby ensuring accuracy and reliability in performance even at low airflow. We offer various VAV terminals with electric reheat, hot water reheat, series and parallel fan powered terminal, thus providing efficient control for varied and larger temperature range with wide range of airflows to choose from.

Also available without thermostat as a CAV, for constant flow regulator application. Pressure dependent bypass type VAV also available for the use with the system, without air handler drive.

ZONE CONTROL TERMINAL

This terminal is designed to provide minimum-maximum flow control for on demand ventilation. It combines the functionality of an accurate and very low airflow measuring device with motorised control damper.

It provides cost effective treated fresh air control for hotel guest rooms. Each terminal is tested rigorously, thereby ensuring accuracy and reliability in performance even at low airflow.

We also offer optional room controller to provide demand control ventilation based on occupancy. It can be integrated with multiple space VAQ and its controller, to optimise the blower speed of heat recovery or fresh air unit in accordance with the each room's airflow requirement.

3. WIRE-FREE SOLAR IAQ CONTROLLER

A totally wire free and portable unit that monitors indoor air quality, complete with CO , Temperature and Humidity sensors with set-point adjustments. It has 2 a highly efficient indoor solar cell to harvest its own power from ambient interior lighting. It has a large display screen to facilitate reading from a distance.

It also has an advanced application specific control for with easy integration with VAQ stations.

An optional smoke detector can be connected with this controller to provide early alarm in case of fire and at the same time strategise and control VAQ stations, fire smoke damper and other smoke exhaust systems using Intelligent Damper Control and Monitoring System.

It's unique portable design and RF communication means it has zero installation hassles with no wires and conduits.
