An obligatory link in the transfer of products from the producer to the consumer is transport, which must ensure the transfer of products without damage, with the maximum preservation of its quality. From this point of view, vehicles for the transportation of agricultural and food products attract special attention, since these products are easily exposed to pressure, temperature and mechanical damage. One of the most important ways to preserve the quality of products during transportation is the use of vehicles equipped with various types of refrigeration devices. For this, it becomes necessary to develop new vehicles that will be equipped with economical, highly efficient and acceptable refrigeration devices. A schematic diagram of a vehicle equipped with an absorption-type refrigeration machine, which is completely powered by the heat of the vehicle's exhaust gases, is presented. R

Global pressure has intensified to reduce the use of R404a with high global warming potential and relatively high leak rates in supermarket systems. In Europe, several design modifications such as cascade systems and new refrigerant choices are being investigated. One of the new leading options is to utilize a hybrid cascade system using CO2 in low temperature refrigeration circuit and R134a in medium temperature. R134a has higher efficiency than R404a and about one third the direct global warming potential (GWP). To make even greater gains in GWP reduction, a new lower GWP refrigerant has been developed that is retrofittable in the medium temp R134a circuit with minimal system changes. This refrigerant has less than half the GWP of R134a and is also non-flammable. This paper will show results of experimental calorimeter and supermarket system performance. A TEWI analysis will also be presented to demonstrate the significant reduction in environmental impact if XP10 is used in a hybrid cascade system with CO2.
