Abstract:

This research simulates and experiments with the passive cooling heat-pipes heat-exchanger and solar energy capability in reducing the cooling energy consumption. The computational fluid dynamics satisfactorily converge all the properties and the conditions using the RANS method to solve the velocity components, pressure and k-ɛ (epsilon) scheme. Regarding the experiments, the capabilities of the heat-pipes heat exchanger in reducing temperature were tested with a test box in five opening configurations. The simulations by the computational fluid dynamics and the experimental works on the heat-pipes heat-exchanger combined with solar energy found that the power consumption could be reduced in the range of 93 W/m³ to 140 W/m³ or about 25% to 33% of the room’s required energy. It is significant that the heat-pipes heat-exchanger reduces room temperature while solar energy reduces the dependence on grid electricity. Thus, the combined solar energy and passive cooling have a huge potential in reducing energy while maintaining comfort cooling.
