color=#0000ff size=2>To reflect the effect of the boiler and the fluid cooler
that are attached to the heat pump loop and also considering the heat pump COP
and EER (in heating and cooling modes), I modeled the water to water heat
pump system as a distributed heat pump system. In this case the efficiency
of the distributed heat pumps were adjusted based on the efficiencies of water
to water heat pumps.</FONT></SPAN></DIV>
