<p>Paris,</p>
<p> You are on the right track. There are a number of other heat
pump models available in the TESS HVAC library; like Type143 they
too will give you COP as a function of entering conditions. They
differ from Type143 in that the Type143 external performance data
file is for a specific heat pump capacity while the heat pumps in
the TESS library have normalized performance data files and the
heat pump capacity is entered as parameters to the model.<br>

<p>kind regards,</p>

<p class="MsoNormal">I understand that the cooling and heating
energy demands generated by Type56 are thermal energy. If I
use a heat pump, that has a certain COP, to provide the
cooling and heating energy, does this mean the electric energy
requirement of the heat pump is (cooling + heating
energy)/COP? Can type 143 be used to calculate how the COP
change? Is there any other type that I can use to calculate
the COP?<o:p></o:p></p>
