The thermometer and the barometer were born in the 1600s and, since then, sensors used for environmental purposes have ...

Recent advances in the types of gas sensors available have created new opportunities for engineering smart products that can consider the air quality and smell, thus providing more information to ...

This coolant is compressed, which significantly increases its temperature, and is then moved to the designated heat location, where the heat is extracted by either passing air or water over the hot ...

For years, the conventional VAV control sequence included the reheat valve controlling directly to space temperature. More and more often, discharge air temperature (DAT) sensors are now being ...

In the first installment of this series, "Calculating a practical hotspot safety margin", we discussed how two-parameter thermal models assume that the entire motor, including windings, exhibits one ...
