These motors are sometimes called DC motors, sometimes EC motors and occasionally DC/EC motors. DC stands for direct current and EC stands for electronically commutated.. DC motors allow the speed of the fans within a fan coil unit to be controlled by means of a 0-10 Volt input control signal to the motor/s, the transformers and speed switches associated with AC fan coils are not required.
Centrifugal fans blow air at right angles to the intake of the fan and spin the air outwards to the outlet (by deflection and centrifugal force). The impeller rotates, causing air to enter the fan near the shaft and move perpendicularly from the shaft to the opening in the scroll-shaped fan casing.
Cooling fans - (also referred to as "cooling tower fans") - These are axial fans, typically with large diameters, for low pressures and large volumes of airflow. Applications are in wet mechanical cooling towers, air-cooled steam condensers, air-cooled heat exchangers, radiators, or similar air-cooled applications.
GeekWire is an American technology news website that covers startups and established technology companies. The site launched in March 2011 [1] and is based in Seattle.It was founded by journalists Todd Bishop and John Cook with investment from Jonathan Sposato.
The original Jenn-Air Products Company was founded by Louis J. Jenn in Indianapolis, Indiana, in 1947, later becoming simply Jenn-Air. [2] In the early years, the company was focused on manufacturing and marketing of industrial fans for use in a variety of commercial and industrial applications.
To cool these components, fans are used to move heated air away from the components and draw cooler air over them. Fans attached to components are usually used in combination with a heat sink to increase the area of heated surface in contact with the air, thereby improving the efficiency of cooling. Fan control is not always an automatic process.
