Hello everyone,
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).
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.
Load side flow-rate also goes from 0 to 0.5 to 1 but there are bigger temperature changes according to the demand.
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.
Can someone with a better understanding about H.Ps take a quick look and see if this graph is
reasonable compared to the performance curve?
Thanks in advance
