Abstract
Disclosed is a method of operating a trailer refrigeration unit of a refrigerated trailer system comprising setting a cargo hold set point temperature through a user interface; urging an airflow along a flowpath from a return air inlet port, through an evaporator of the trailer refrigeration unit, and to a supply air outlet port of the trailer refrigeration unit; monitoring a return air temperature of the airflow flowing through the return air inlet port; monitoring a supply air temperature of the airflow flowing through the supply air outlet port; heating the airflow flowing through the supply air outlet port when the return air temperature is less than the cargo hold set point temperature; and stopping heating of the airflow flowing to the supply air outlet port when the return air temperature is less than the cargo hold set point temperature and the supply air temperature reaches a threshold.
