Trusted Flow Measurement

    Posted on Tue,Aug 20, 2019 @ 08:32 AM
    Glycol is commonly used to prevent heat transfer fluids freezing in heating, cooling, and air conditioning systems. It is typically found in systems where pipework is exposed to the exterior environment – rooftop units, free cooling, cooling towers, district cooling systems, and green energy applications, such as solar thermal collectors. Glycol into any system can result in large errors in thermal energy measurement when using a meter intended for water alone.

    The Importance of Specialized HVAC Systems for Grow Rooms

    Posted on Tue,Aug 06, 2019 @ 04:13 PM

    Cannabis is one of the most valuable crops in North America, with over 2 million grow rooms in the United States and approximately 700 in Canada. Analysts estimate the legal cannabis market will be worth over $21 billion in 2021. The cannabis industry presents tremendous opportunities for HVAC businesses because of its enormous indoor growing area size. The grow rooms are considered critical environments and need specialized equipment to keep crops healthy, productive, and sustainable.

    The Glycol Measurement Challenge

    Posted on Tue,Jul 30, 2019 @ 11:58 AM

    Glycol is commonly used to prevent heat transfer fluids from freezing in heating, cooling, and air conditioning systems. It is typically found in systems where pipework is exposed to the exterior environment – rooftop units, free cooling, cooling towers – and also in green energy applications, such as solar thermal collectors. Glycol may also be used in district cooling systems – for example, in high rise properties – and low temperature energy networks serving a number of customers. However, the addition of glycol into any system can result in large errors in thermal energy measurement when using a meter intended for water alone.

    Why is it necessary to monitor CO2 concentration in buildings?

    Posted on Thu,Apr 25, 2019 @ 12:25 PM

    Controlling and monitoring indoor levels of carbon dioxide is essential for everyone’s health, safety, and the energy efficiency of buildings. Similar to how we need to breathe fresh air, so do buildings. Ventilation in a building is the essential process of replacing stale air with fresh air. Without engineered ventilation, buildings become susceptible to stagnant air, mold, bacteria, and potentially harmful gasses like radon, VOCs (volatile organic compounds), and carbon dioxide. Prolonged exposure to these elements can lead to “sick building syndrome” where occupants experience acute health and comfort effects.

    The Importance of Measuring Air Pressure in Commercial Buildings

    Posted on Tue,Mar 26, 2019 @ 12:29 PM
    This article explains why and how to measure air pressure in commercial buildings ensuring occupant comfort and building efficiency. Topics covered include:
    • Air pressure and how it affects commercial buildings
    • Effects of not managing building air pressure correctly
    • How to control the air pressure
    • Measuring pressure
    • Calibration
    • Installation advice and setpoints

    Air pressure is the weight of air molecules pressing down onto the earth and objects. (refer to Figure 1). For instance, cool air molecules are heavier and denser causing the force applied to a structure to be greater while warm air molecules are lighter and have lesser force on the building. There are other complicating factors such as wind, weather and seasonal changes, which will also produce variations in pressure.

    Sensors are the Foundation for Occupant Comfort

    Posted on Tue,Nov 27, 2018 @ 04:35 PM

    In HVAC systems, sensors measure controlled variables of temperature, humidity, pressure, and air quality.  Sensor inputs connect to the Direct Digital Control (DDC) system and network to the Building Automation System (BAS).  High quality sensors are the foundation for ensuring occupant health and comfort and are essential for energy efficiency within buildings.

    Pressure Sensors Optimize Building Performance

    Posted on Mon,Nov 05, 2018 @ 12:44 PM

    HVAC system performance and comfort rely on accurate measurement and control of differential pressure.  Effective air distribution is achieved by closely monitoring and controlling air pressure.  By monitoring the airflow pressure across dampers, filters, fans, and between rooms, the HVAC system can efficiently and economically optimize building performance and reduce energy consumption.
