A transportation refrigeration system operable in a cooling mode, a defrost mode, and a heating mode to condition air in an air-conditioned space. The system comprises a refrigeration circuit fluidly connecting a compressor, a condenser, a tank, and an evaporator. The evaporator is in thermal communication with the air-conditioned space. A heating circuit fluidly connects the compressor, the tank, the evaporator, and a heater. A defrost circuit fluidly connects the compressor, the tank, the evaporator, and the heater. The tank has a base and the first opening is spaced a first distance above the base and the third opening is spaced a second greater distance above the base.
