I am not familiar with Type401. However, there are a number of heat
pump models in the TESS Libraries and they probably work about the
same. The problem with the existing models from your point of view
is that they take the entering conditions (of air and water) and
they compute the power required by the heat pump. I am not aware of
any heat pump models that take power available as an input. I think
you might still be able to achieve your simulation however. You need
to first find the threshold power above which the heat pump can run
(perhaps this would be the rated power? perhaps it would be the
lowest power listed in the performance data?) Run your PV array and
whenever its output power is above the heat pump's minimum allowable
power then run the heat pump. You can write an equation that will
multiply the thermostat's heat/cool signal by the PV's "power
available" signal.<br>
