Abstract
Nowadays, humankind is facing problems with global energy deficiency and global warming. During hot periods or in hot climate regions people use traditional cooling methods. These methods use energy to cool the whole space and are not energy efficient. To face the problem, the application of impinging jets for direct cooling of occupants was proposed. Numerical investigations were done in Ansys CFX and thermal comfort was measured by the CBE comfort tool. The domain for impinging jets had three jets with the same diameter of 8 cm. One of the jets was normal to the occupant, while the rest were focused on cooling the head, shoulder and waist regions. Results showed that impinging jets can provide thermal comfort and are an energy efficient solution that can save 18.3% of energy.
