 The controls engineer shrugged, spreading his hands. "Sure, but with the single transducer to monitor eight tubes, we won''t know for three to five minutes after the pump command is sent.""Can we live with that?" asked the manager, glancing around the table at each member of the assembled group of microbiologists and chemical engineers.One of the engineers tapped at his personal digital assistant, then spoke up, "Even at 32 mils a minute, the pressure buildup from the recirculation pump won''t be enough to trigger the relief valve. I think it''s in the noise." Efficiency is further enhanced with the use of magnetic bearings, which avoid fire friction of rubbing parts associated with traditional oiled bearings. Conventional bearings can use as much as 10,000 w, while magnetic bearings require only 180 w. That amounts to 500 times less friction loss. Current development projects are expanding the range and duty of the compressor wheels and promise to offer even greater efficiency for water-cooled and air-cooled duties and different buildingabackyardfirepit capacities.CONTROLSThe new compressor effectively is a computer. It provides diagnostic and performance information through Modbus to the refrigeration system, which then communicates to the building automation system through Modbus, LonWorks, or BACnet.CHILLER APPLICATIONThe compressor manufacturer and a major chiller manufacturer teamed up to develop a line of ARI-certified water-cooled chillers, which were expected to be introduced in January 2004. The combination of flooded-evaporator technology and an oil-free system has allowed very close approaches and, subsequently, enhanced performance. The integrated VFD allows excellent part-load performance as power consumption drops off, depending on the head relief, near the cube root of the shaft speed.
