Air-quality sensor controls ventilation to requirements

vES
Ventilation can be matched to demand using VES Andover’s AQ sensor, which responds to both carbon dioxide and volatile organic compounds.
An air-quality sensor for VES Andover’s range of air-handling units measures carbon dioxide and volatile organic compounds in rooms or ducts and provides a signal that can be used to adjust air volume and other functions. Such demand-controlled ventilation can reduce energy consumption by up to half. AQ sensors cost less than £200 and are delivered with default settings. If required, the weighting between carbon dioxide and VOCs can be varied. A carbon-dioxide weighting should be used for spaces where the number of people varies — such as shops, sports clubs and meeting rooms. VOC weighting should be used for environments with odours such as cooking, toilets and garage exhaust fumes. The sensor sends a 0 to 10 V signal direct to the fan-speed controller. Single- and 3-phase fans can be controlled.
