Numerical analysis is being conducted to investigate the effect of Nano fluids on the melting process of phase change materials (PCMs) in a semi-cylindrical container. Nowadays, mitigating climate-altering emissions resulting from air conditioning and mechanical ventilation of indoor spaces is of utmost importance.
Most conventional SWHSs are forced circulation systems with solar collector arrays . With an ON/OFF differential temperature sensing controller, the heat transfer fluid flows at a constant rate circulated by an AC pump. The temperature difference between the outlet temperature of the collector array and the outlet temperature of the tank is the control signal.

On the other hand, forced circulation systems imply certain drawbacks: The system requires the installation of a water pump to allow water circulation. The presence of the pump implies an increase in maintenance costs since there are more elements with the possibility of suffering breakdowns.
Forced systems are always indirect, except for pool air conditioning uses where the pool's water filtering drive system itself can be used. By using an external energy source, this form of solar energy harvesting can no longer be considered a passive solar energy system. The structure of the house does not determine its location.
