Refrigerated trucks (RT) typically carry an extra diesel engine and therefore require extra fuel to power their large, refrigerated trailers (even though 60% of the energy in the truck’s main engine is wasted as heat). Our system changes this reality and uses this energy waste to power the refrigeration cycle of RTs. The project is a replacement of the existing power unit on refrigerated trailers with an aftermarket waste heat recovery system to eliminate the fuel consumption of the refrigeration unit. This saves the user around 50 liters of diesel fuel per day, which is more than $1,500 a month and cuts carbon emissions by 40,000 kg of CO2 yearly per truck.
