Imagine you sit down at a restaurant on the outdoor patio, and as you’re waiting to order your food, you glance at the large HVAC system on top of the building across the street. Several questions cross your mind: Why do they need such a big system? And what goes into it? Today I want to introduce one of the vital aspects of a building’s HVAC system, the air handler.

Parking Garage Ventilation Control
The Series GSTA carbon monoxide/nitrogen dioxide gas transmitters offer a robust, low cost alternative to standalone garage ventilation control packages.
As cities around the world continue to grow, the need for parking becomes an integral part of new commercial and municipal building plans. Many building designers are finding ways to offer adequate parking in a limited amount of real estate. Two emerging trends to do so are enclosed parking garages and mixed-use parking garages. Both of these designs seek to offer users a comfortable way to park their vehicles, all while being near their final destination. This means that the parking facility and the commercial or residential buildings are not separated, but are integrated together into one building structure. Due to this integration, two major concerns arise. How do we ventilate the harmful exhaust from the vehicles while being so close to the populated areas of the building, which require clean air and how do we accomplish this in the most energy efficient way possible? The Dwyer® Series GSTA carbon monoxide/nitrogen dioxide gas transmitters offer the sensory inputs necessary for any building automation system to answer this very quandary in an efficient and low cost manner.

Importance of Sensor Stability in Educational Facilities
Educational facilities, or public and private institutions devoted to teaching students, differ in physical size and level of education programs. These institutions can range from preschool to university levels, all of which need proper heating, ventilation, and air conditioning (HVAC) systems and indoor air quality.
While indoor air quality (IAQ) is important for everyone’s health, it is especially important for young children that are still developing their lungs. The United States Environmental Protection Agency (EPA) Science Advisory Board has completed multiple school studies that show indoor air pollution among the top five environmental risks to public health.

Digital Chiller Thermostats
Commercial Refrigeration Thermostats Go Digital for Greater Control
In the past, bulb and capillary mechanical thermostats were used in chillers to maintain proper water temperature. As technology has advanced, digital temperature switches have replaced many mechanical ones because a digital temperature switch provides the same functions while also serving as a timer, external relay and thermometer. Where are digital temperature switches used, and which features have caused the conversion? Continue reading “Digital Chiller Thermostats”
