<SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: Tahoma">I am trying to calculate/estimate the electricity consumption by a chiller based on hourly outputs. <?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /><o:p></o:p></SPAN><BR>

<SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: Tahoma">but the calculated annual electricity consumption was not even close to the numbers reported under Space Cooling Enduse.<o:p></o:p></SPAN><BR>

<SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: Tahoma">Then, I used PLR and operating chiller capacity at current condition to calculate CAP hour (instead of using the cooling coil load on loop), but calculated numbers did not make any sense.<o:p></o:p></SPAN><BR>

<SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: Tahoma">Has anyone done similar calculations? I am sure I am missing something very simple here, but what?<o:p></o:p></SPAN><BR>
