Abstract:
A transport temperature control apparatus operable in a cooling mode and a defrost mode, the apparatus comprising:a refrigeration circuit; a heat exchanger having an air inlet and an air outlet, the air inlet and the air outlet being in fluid communication with a conditioned space; an evaporator coil extending through the heat exchanger between the air inlet and the air outlet and being fluidly connected to the refrigeration circuit; a divider substantially perpendicular to the evaporator coil, the divider defining a first portion of the evaporator coil and a second portion of the evaporator coil; a first fan housed in the heat exchanger and being positioned adjacent the first portion of the evaporator coil, the first fan having a first operating condition for directing air across the evaporator coil in a first direction and a first non-operating condition; and a second fan housed in the heat exchanger and being positioned adjacent the second portion of the evaporator coil, the second fan having a second operating condition for directing air across the evaporator coil in a second direction and a second non-operating condition, the second direction being opposite the first direction.
