Özet:

In this thesis, the possible usage of phase change materials in military shelters with the aim of decreasing the heating effect of the solar radiation is presented. In order to meet the rapidly growing demand for energy in military applications, a passive cooling technique, specifically, storing thermal energy with phase change materials is analyzed by using experimental approach. Not only different types of phase change materials but also different amounts of them are examined during the solar loading experiments. In order to simulate solar heat loading on prototype military shelters, solar radiation test or in other words sunshine test that is stated in military standard MIL‐STD‐810G, Environmental Engineering Considerations and Laboratory Tests, is used. Besides, in order to simulate the real world, solar radiation heat fluxes in Ankara are calculated and solar radiation tests are repeated according to the calculated solar radiation heat fluxes.
