Data Center Tridium HVAC Control Panel - As data centers go and HVAC controls function are typically done controlled with either direct digital controls or a very complex SCADA system with direct digital controls being the preference in most situations.
Tridium is a developer of direct digital controls software and hardware and Tridium specializes in controls integration through the Tridium software they develop that allows different devices and different communication protocols to communicate to one another. (more…)
Air Handler Filter Pressure Sensor - This is a pressure sensor. It tells a maintenance technician if the air filters are dirty and clogged. The pressure control is a low static pressure switch to trip the unit if the mixing box drops below the setpoint pressure. The pressure the switch is calibrated to.
In addition, the low static pressure sensor protects the fan and the ductwork including dampers from damage. If the economizer damper and the return air damper would fail closed (or another possible scenario) that would cause the unit to pull negative pressure in the mixing box. (more…)
Proper HVAC Fan Maintenance and Control can Save Energy Dollars
Fan Maintenance Energy Savings - According to the Department of Energy fans consume nearly 80 billion kilowatts of energy per year. Optimizing how fans work functionally in mechanical applications can reduce energy use and save energy dollars for end users.
Assuming the design engineer selected the proper fan and proper installation in the well-designed system what can a facility manager do to save energy dollars and increase performance by looking at the fan systems in their building(s)? To make a good evaluation you need to look at several different factors in fan operation.
York Variable Frequency Drives VFDs | HVAC Control - Variable Frequency Drives or VFDs have added a whole new dimension to energy efficiency and control. These drives, or VFDs, are hooked up to two different York VAV air handlers that have two three-phase motors a piece. (more…)
HVAC Tip - Some people refer to refrigerant as Freon. So when something is wrong with their HVAC system they say, “I have a Freon leak”. Freon is a name trademarked by Dupont for R-22. R-22 is being phased out because it contains chlorine. While Freon will soon be a thing of the past, the name Freon has found its way in our lexicon as a reference to refrigerant, any type of refrigerant.
