Abstract

A method for air temperature control within a cargo compartment of a transport unit using a transport refrigeration system (TRS) that includes a thermal accumulator having a phase change material (PCM) provided therein is provided. The thermal accumulator is disposed in a thermal accumulator compartment and the cargo compartment is separated from the thermal accumulator compartment via a climate controlled barrier. The method includes a controller receiving, via one or more temperature sensors, temperature data within a cargo compartment of the transport unit from. The method also includes determining a temperature within the cargo compartment based on the temperature data. Also, the method includes determining a temperature stratification within the cargo compartment based on the temperature data. Further, the method includes operating the TRS in an active operation mode when the temperature within the cargo compartment is greater than a temperature set point.
