systeemkromme

The term “systeemkromme” refers to a system curve, a graphical representation used primarily in the field of heat pumps and refrigeration systems. It plots the relationship between the temperature difference across the system (the supply‑side temperature minus the return‑side temperature) and a performance metric such as the coefficient of performance (COP) or the actual power consumption of the unit. By examining the curve, engineers can determine how efficiently a heat pump will operate under different load conditions and design operating constraints accordingly.

In practice, a system curve is derived from a series of experimental data points collected at various operating points. The data are typically plotted with the temperature difference on the horizontal axis and the indicated performance measure on the vertical axis. The resulting curve often shows a negative slope, indicating that higher temperature differences lead to lower COPs and greater power consumption. Engineers may use the system curve to establish a feasible operating band, ensuring that the heat pump remains within provisions for both efficiency and safety.

System curves are also employed to compare different units or to assess the impact of system modifications. By overlaying curves from different configurations, designers can identify which setup delivers the best performance for a given range of temperature differences. Overall, the systeemkromme is an essential tool for optimizing HVAC installations and for validating the performance of heat pump technologies.
