A transportation climate control system for providing climate control to a climate-controlled space of a transportation unit. The transportation climate control loop includes a compressor, an evaporator, and at least two fans. The transport climate control loop also includes a controller for controlling the transport climate control loop and for defrosting the evaporator coil. When a defrost event is triggered, the controller commands the transport climate control loop to supply heat to or around a section of the evaporator coil; and independently controlling each of the at least two fans to move air around the evaporator coil in a controlled direction such that heat from the one section of the evaporator coil is used to convectively heat an inlet of the evaporator coil.
一种用于向运输单元的气候受控的空间提供气候控制的运输气候控制系统。运输气候控制回路包括压缩机、蒸发器和至少两个风扇。运输气候控制回路还包括用于控制所述运输气候控制回路以及用于对蒸发器盘管除霜的控制器。当除霜事件被触发时,所述控制器命令所述运输气候控制回路向所述蒸发器盘管的一个区段或该一个区段周围供应热;以及独立地控制所述至少两个风扇中的每个风扇以使空气在所述蒸发器盘管周围沿受控方向移动,使得来自所述蒸发器盘管的所述一个区段的热被用于对流地加热所述蒸发器盘管的入口。
