ABSTRACT:
A transport refrigeration system having a refrigerant compressor which is selectively operable with either an electric motor or an internal combustion engine. The transport refrigeration system conditions a load space to a selected set point via heating and cooling modes in response to a selected one of either a return air sensor or a discharge air sensor. System control is automatically optimized in response to manual selections of the prime mover and the operative sensor by providing first, second, third and fourth control algorithms. Selection of the return air sensor automatically selects the first and third control algorithms for electric motor and internal combustion engine, respectively, and selection of the discharge air sensor automatically selects the second and fourth control algorithms for the electric motor and internal combustion engine, respectively.
