The invention provides a refrigerator car and a heating unit thereof. The heating unit comprises a compressor, an indoor heat exchanger and a gas-liquid separator, wherein an inlet of the indoor heat exchanger is connected to an outlet of the compressor by virtue of a first pipeline, and the first pipeline is provided with a defrosting control valve; an inlet pipe of the gas-liquid separator is connected to the outlet of the compressor by virtue of a second pipeline, an outlet pipe of the gas-liquid separator is connected to the inlet of the compressor, the second pipeline is provided with a heating control valve, and an outlet of the indoor heat exchanger is connected to the inlet pipe of the gas-liquid separator. By adopting the heating unit, gaseous overheated coolant at an exhaust side of the compressor is mixed with liquid coolant at the outlet of the indoor heat exchanger, the coolant sucked by the compressor is ensured to stay at a low-pressure vapor state, so that the compressor can apply more work to the coolant, the temperature of the coolant heated by the indoor heat exchanger is higher, the liquidation of the coolant can release more heat, the heat exchanging efficiency when heating in a refrigerator car carriage can be improved, the temperature fluctuation in the carriage can be reduced, and the temperature inside the carriage can be accurately and stably controlled.
