<DIV><FONT face=Arial size=2>James Hirsch & Associates is currently
implementing new chiller algorithms in DOE-2, and defaults performance
curves for screw chillers will be included. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2><FONT face=Arial size=2>For both reciprocating and
screw chillers, the program will use different performance curves depending on
the number of compressors in the machine. The program will also model
centrifugal chillers with variable-speed drives. </FONT>Since some of these
curves utilize new types of CURVE-FITS, they require a new version of
DOE-2.2 which won't be released for another month or two.</FONT></DIV>

the following models a water-cooled screw:</FONT></DIV>
