A transport refrigeration unit includes a combustion engine (66) system having a turbocharger (70) constructed and arranged to receive air in a cold state and expel the air in a compressed hot state, an evaporator (50), and a defrost heat exchanger (78) constructed and arranged to receive the air in the compressed hot state and expel the air in a compressed cooled state for defrosting the evaporator (50). In operation, the unit may be capable of controlling a defrost temperature and/or controlling the temperature of the air entering a combustion engine (66) of the engine system for combustion by controlling the volume of air flow between the defrost heat exchanger (78) and a charge air cooler (68) of the engine system. |
