Abstract

This article aims to define the indoor and outdoor air temperature to develop a two-phase Thermosyphon implemented on the roof for passive cooling. For this, an experiment was carried out with a small-scale project and two parameters were varied: the cooling temperature of the thermostatic bath and power. The results show that the temperature gradient between the evaporated and condensing sections is fundamental for developing the system. Thus, the test with a power of 25W and a thermal bath temperature of 16 °C, which has the best temperature gradient (15.51 °C), the best thermal performance.
