Hypothesis and equations
Called ISWH for individual solar hot water heater, this domestic hot water production system combines a solar sensor and a domestic hot water tank with an electric back-up.
It combines a solar sensor model and a domestic hot water model. Heat recovered by the plane sensor is transferred to the hot water tank.The hot water tank can be placed in a room heated or not. Refer to the sensor and the tank models for more information on their specificities.

This is a simplified model that does not take into account the heat transfer fluid, thus neither the sensor inertia nor the consumption of fluid circulation auxiliary are not taken into account.
Take care to respect the units of inputs such as the drawing scenario rate in kg / h.
