<p class=MsoNormal><font size=2 face=Arial><span lang=EN-GB style='font-size:
10.0pt;font-family:Arial'>Recently I requested help (and got it, thank you very
much) with regard to the heating and cooling demand of a 20 sqm zone representing
a room in a building with one façade fully glazed and a fan coil unit
specified. After consideration it was concluded that the heating demand
calculated with eQuest was reasonable however the cooling demand was very very
small. The chiller chosen was an electric-hermetic-reciprocating chiller (at
random because I didn’t know any better) with an EIR of 0.25 (COP=4.0)
and after a long time investigating I changed the chiller to a
electric-hermetic-centrifugal chiller and kept the EIR at 0.25. This resulted
in the cooling load quadrupling! Does anybody know why this should be the case
when every other parameter remained the same?<o:p></o:p></span></font></p>
