PROBLEM TO BE SOLVED: To provide a method and a unit for automatically defrosting an evaporator coil of an air-conditioner without any manual operation and without using any static pressure. SOLUTION: In the unit and the method for controlling the transport temperature for defrosting an evaporator coil of a transport temperature control unit, the transport temperature control unit comprises an evaporator coil, an ambient temperature sensor to detect the ambient temperature, a return air temperature sensor to detect the return air temperature, an exhaust temperature sensor to detect the exhaust air temperature, an evaporator coil temperature sensor to detect the evaporator coil temperature, and a control unit to start the defrosting cycle when a large differential temperature occurs in the evaporator coil. In this method, the temperature sensors connected to the control unit operable to control the transport temperature control unit are provided, temperatures are detected by the temperature sensors, and transmitted to the control unit, the defrosting cycle is started by the temperature transmitted to the control device, and the control device starts the defrosting cycle.
