How to create an air-water hybrid heat pump, an air-solar hybrid heat pump, and an air-water-solar hybrid heat pump using Simulink?"

I have an air-source heat pump example in Simulink, and I want to add water and solar thermal sources to create a hybrid heat pump. Can you tell me how to do this?"

I understand that you are looking at the air-source heat pump:

Adding heat sources is a matter of figuring out:

1. How you will model the extraction of heat from your source - Microchannels in a solar collector, or a simple source of heat? For your water, can you route it to a heat exchanger, you submerge pipes into a large thermal reservoir, etc.?
2. How you will integrate its heat into your heat pump - Do you heat the refrigerator fluid, the thermal liquid of the house, add a new refrigerator loop, etc?

You can see the ground-source heat pump example for inspiration:

The ground is modeled as a temperature source with a second thermal fluid that collects its heat and transfers it to the refrigerator fluid. You could make two refrigerator loops to add air and water sources maybe?

For your solar collector, I would use this model as reference. It is photovoltaic, but it does consider heat transfer:
