According to TUIK's (Turkish Statistical Institute) 2020 greenhouse gas emission inventory data, 94.9% of CO2 emissions from transportation are caused by road transportation. The leading sector in road transportation is refrigerated product transportation. The reason for the importance of refrigerated product transportation is that additional fuel is consumed for the cooling of the product and the emission emission increases accordingly. In this study, a theoretical analysis of the cooling of a certain product in a refrigerated trailer with solar energy support was made and its effects on energy, cost, fuel consumption and CO2 emissions were investigated. For this purpose, a trailer whose technical specifications and dimensions are known from the company catalogs and used in commercial applications has been selected and it is thought that mono-crystalline solar panels are placed on the top and side surfaces. The energy obtained from the panels will be used in the cooling unit. The trailer with solar panels is assumed to move in the city of Istanbul. In the selection of the cooler and evaporator, one of the brands with the highest sales rate in the market was chosen. The cases of cooling the trailer when it is empty and cooling the trailer when the product inside is frozen fish are analyzed. In July, the month of the year with the highest radiation intensity, 29% of the electrical energy consumed by the cooling system was provided with the energy obtained from the panels. In this case, 30% of the fuel consumed by the cooling unit can be saved with the energy provided by solar panels. This will reduce emissions, contribute to the protection of nature and reduce the cost of product transportation.
