Research on energy saving optimization method of electric refrigerated truck based on genetic algorithm

Systematic Opportunity Scan of Energy Recovery Technologies Applied to Trucks with Electric Refrigerated Units

“…In turn, the work of Song et al [34] elaborates the research based on the justification that refrigerated trucks have high rates of cargo damage, which is the result of the unstable temperature inside the cold room. It is presented by the research that, in recent years, electric refrigeration trucks have been designed where the all-electric refrigerated chamber is a new type of chamber featuring higher efficiency.…”

“…The refrigeration system of the electric refrigerated truck used as a reference for the research carried out by Song et al [34] is composed of auxiliary equipment such as compressors, condensers, evaporators, expansion valves, and pumps. In the case of this vehicle, the compressor is driven directly by the high-voltage DC/AC motor.…”

“…There are two types of vehicles with these units: independent, where an independent motor drives the compressor, and non-independent, which depend on the vehicle's motor [33]. In the refrigeration system of electric refrigerated trucks, made up of auxiliary equipment such as a compressor, condenser, evaporator, expansion valve, and pumps, the compressor is the main source of energy consumption [34]. In the case of the mechanical refrigeration truck with a non-independent refrigerator, the compressor is driven directly by the vehicle's gasoline or diesel engine [34].…”

Both types consume a significant amount of energy to cool the inside of the trailer body, according to the demands of the products being transported.…”

Net Zero Roadmap Modelling for Sustainable Dairy Manufacturing and Distribution

“…Where, U en is the overall heat transfer coefficient of the chamber or refrigeration unit enclosures, which was calculated as presented in [62] and [63] respectively, and A en is the heat exchange surface of the enclosure, T pr is the storing temperature of products in the cold storing chamber and T amb is the ambient temperature or the temperature outside of the storage chamber. More details on calculating the thermal load for cold storage chambers and refrigeration units of vehicles can be found in [62] and [63] respectively.…”
