Heat pump and chillers: calc_cops() parameters temp_high and temp_low: T of flow or reservoir? #110

Open SabineHaas opened 4 years ago

My question regards the heat pumps and chillers function calc_cops() and more specifically the parameters temp_low and temp_high. In the documentation they are described as "Temperature of the low/high temp. heat reservoir" (see here).

In this heat pump example temp_high is 65°C, which looks to me more like the temperature of the outflow of the heat pump (f.e. flow that heats a room), not the temperature of the reservoir (f.e. room temperature).

Should I take the temperature of the outflow or the (in my case) room temperature as temp_high?

@SabineHaas I think I answered your question already on other channels. temp_high is the flow temperature.

I would suggest to adapt this in the docu (or at least give a hint) since it might be misleading.
