VSD installation cuts power consumption by almost 50 percent

Article Abstract:

George Mason University in Fairfax, VA, employs the variable-speed drive (VSD) technology in a move to upgrade the facility's air-conditioning blower system. The facility also requires combined blower control to its direct-digital control energy-management system to allow remote temperature and room-pressure monitoring. The school's VSD system is installed with almost nine sq miles of cable that will provide the two-way communication between the pneumatic vane-control system and the energy-management system.

Breathe deeply

Article Abstract:

The diecasting and foundry industries presents two of the most challenging working environments in manufacturing. In both types of facilities, ventilation plays a major role in the premature wear and tear of equipment, high cost of maintenance, product quality and the health of the entire workforce. Designers of such facilities are advised to incorporate large amounts of outdoor air in order to offset exhaust air that are generated in such environments.

A portable solution cools hospital during expansion

Article Abstract:

Carrier Corp's HVAC Portable Systems were used during the addition of a cardiovascular research and surgery center at Houston, TX-based St Luke's Episcopal Hospital and the Texas Heart Institute. The 210-t- air-cooled chillers provuided the 2,100 tons of temporary cooling as the facility's underground chilled-water piping system was excavated and rerouted. The portable systems worked without problems, within four days the main chiller was back online.
