I got the results from a simulation and I think I am getting inconsistent results when comparing the heat pump COP and comparing it normalized performance data sample included with the component, which is the one I am currently using (type 927).</div>

<span style="color: rgb(0, 0, 0); font-family: Calibri, Helvetica, sans-serif; font-size: 12pt;">The system is basically two identical heat pumps (50RT) being controlled by a multi-stage differential controller. (which is also controlling the flow rate for
both source side and load side pumps). So for the load side (connected to a vertical heat exchanger) there is only really small changes in temperature and the flow-rate goes from 0 to 0.5 to 1 following the number of H.Ps on. </span></div>

<span style="color: rgb(0, 0, 0); font-family: Calibri, Helvetica, sans-serif; font-size: 12pt;">Load side flow-rate also goes from 0 to 0.5 to 1 but there are bigger temperature changes according to the demand.</span></div>

<span style="color: rgb(0, 0, 0); font-family: Calibri, Helvetica, sans-serif; font-size: 12pt;">But, according to the performance data, during heating mode, the load side flow-rate should no change normalized capacity and if the load side temperature increases,
normalized capacity should decrease. Which was not what happened with my results.</span></div>
