KMC Controls Releases New, Adaptable Airflow Measurement System

KMC Controls® Releases New, Adaptable Airflow Measurement System

New Paris, IN, August 11, 2022 –(–KMC Controls, an innovator in the building automation and controls industry, has debuted their new KMC Conquest Airflow Measurement System (AFMS), a far more adaptable and accurate solution to measure buildings air intake, an integral factor for occupants health insurance and cognitive function.

As opposed to traditional technologies for measuring airflow, KMC Controls new AFMS could be installed on nearly any kind of ventilation system. Installing the AFMS is normally faster and requires less maintenance over its lifespan than traditional technology, making the AFMS less costly to install and keep maintaining.

Unlike traditional technologies, KMC Controls AFMS consistently obtains airflow measurements that closely match American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) Standard 111, that is popular in testing and balancing air intake in buildings. The technique described in the typical can be approved by the American National Standards Institute (ANSI).

The trick behind KMC Controls innovative technology may be the method that their AFMS uses to measure air intake. Instead of utilizing an old, outdated approach, the KMC Conquest AFMS runs on the brand-new, patent- pending solution to measure airflow called the characterized damper method.

The characterized damper method calculates the exterior air intake utilizing a temperature ratio equation within ASHRAE Standard 111. KMCs AFMS automatically combines those calculations with measurements from additional sensors to understand the exterior air intake of the building equipment.

On the other hand, traditional airflow measurement methods use either differential pressure sensors, thermal dispersion sensors, or fixed outside air inlets coupled with pressure sensors. Each one of these methods has limitations, which usually do not impact KMCs new AFMS.

To measure accurately, differential pressure and thermal dispersion sensors should be installed near another air damper with a particular amount of straight ductwork resulting in the sensors. However, many buildings have ductless outside air systems, or ductwork with bends along with other airflow restrictions.

Fixed outside air inlets with pressure sensors could be installed on ductless systems, however the inlets often require expensive modifications to the prevailing system and could unfit all equipment types. Also, barometric pressure drops during storms can decrease the accuracy of fixed inlet systems.

Additionally, both differential pressure sensors and fixed inlet systems become less accurate when measuring low rates of air intake.

Thermal dispersion sensors measure low intake rates accurately. However, dirt, dust, feathers, cobwebs, or animal waste limit the accuracy of the sensors, which require regular maintenance.

KMC Controls AFMS technology isn’t subject these limitations. The machine doesn’t need straight ductwork or filtered air for accurate measurement and the sensors are installed where outside air was already filtered and flow has stabilized.

Were worked up about the opportunity to create airflow measurement right into a wider selection of building equipment, such as for example rooftop units and unit ventilators, which are normal in schools and commercial buildings, said Erich Kreuter, Vice President of Product Development at KMC Controls. These buildings traditionally have limited options, so we developed our technology to handle their needs. We feel its vital that you verify proper operation of ventilation in these kinds of buildings to make sure occupant comfort and safety.
