A system and method for temperature control for a Transport Refrigeration System (TRS) is provided. Particularly, a method for temperature control of an internal space of a refrigerated transport unit is provided. The method includes determining a measured internal space temperature within the internal space of the refrigerated transport unit. The method also includes calculating, via a TRS controller, a temperature difference between the measured internal space temperature and a desired set point temperature. Also, the method includes adjusting, via the TRS controller, a duty cycle percentage of a liquid line solenoid valve and/or a hot gas solenoid valve based on the temperature difference to control an amount of refrigerant directed to the thermal expansion device and the evaporator and/or an amount of hot gas directed to the evaporator.
