Table 5: Average Solar direct normal irradiation (DNI) and Specific photovoltaic power output (PVout). Studying the locations of the world's 10 Largest Refugee Camps--Kakuma, Hagadera, Ifo and Dagahaley in Kenya; Zaatari in Jordan; Yida in South Sudan; Katumba and Mishamo in Tanzania; Pugnido in Ethiopia; and Panian in Pakistan [33]--digital models were created for the simulation of mobile energy unit possible use in the climatic conditions of these camps. Simulations were made under the assumptions described in Section 2.2. In addition, climate conditions were simulated according to the location of existing largest refugee camps. For digital model creation, the TRNSYS climatic database was used. To assess the impact of PV panels for electricity production and HVAC system operation in temporary camp, two models were created: Case 0: without PV panels (only with diesel generator); Case 1: with PV panels + diesel generator (see Table 8). As seen from the Table 9 (data obtained from the \"Global Solar Atlas 2.0 [32]), all of the world's largest refugee camps are located in regions with rather similar climatic conditions with respect to solar direct normal irradiation. The cooling duration to ensure occupant comfort and wellbeing varies from 762-5426 h annually, while the heating duration is far less--40-190 h annually (see Table 10). The electricity output generated by the PV panels is higher (in most cases) than the total required electricity amount for recreated temporary camps.
