A climate control circuit for a transport climate control system is provided. The circuit includes a compressor, a plurality of evaporators, a suction flow control device, and a controller. The suction flow control device is downstream of the plurality of evaporators and directs the working fluid from each of the evaporators to one of a main suction port and an auxiliary port of the compressor. The controller determines whether each of the evaporators is operating in a fresh temperature range or in a frozen temperature range. For each of the evaporators operating in the fresh temperature range, the controller instructs the suction flow control device to direct the working fluid from the corresponding evaporator to the auxiliary suction port. For each of the plurality of evaporators operating in the frozen temperature range, the controller instructs the suction flow control device to direct the working fluid to the main suction port.
