HeatPumpDetailed --> mistake in calculating Qdot_con(Out)

What is the problem?

• The model AixLib.Fluid.HeatPumps.BaseClasses.CycleHP transfers a heat flow into the condenser, while this heat flow is limited according to a maximal temperature. This is achieved by multipliying Qdot_con with a pre-factor 0..1. The resulting CoP_out is calculated with Qdot_con but only the corrected Qdot_conOut is transferred to the condenser.

Why do we want to solve it?

• Electricity consumption does not fit to the gained heat flow.

How do we want to solve it?

• Since the maximum temperature is a limitation of the actual refrigerant cycle, this parameter should remain in the CycleHP model. Instead of reducing Qdot_con the speed or on-off-signal should be controlled as this consequently adapts the resulting Q_th and P_el.
• If the heat pump is speed controlled: Regulate speed as low as possible to not exceed maximum temperature. If lower speed limit is reached, heat pump is switched off. An on-off-controlled heat pump directly has to be switched off.
• Introduce parameters for time span that has to be between to compressor starts (typically appr. 20 min) and between a stop and a next start (typically appr. 10 min).
