The invention provides a refrigeration device, a control method thereof and a transport vehicle. The refrigerating device comprises a compressor, a first heat exchanger, a liquid storage device, a throttling element and a second heat exchanger in a refrigerating circuit, the refrigerating device comprises a refrigerating mode and a hot gas bypass heating mode, in the hot gas bypass heating mode, refrigerants leaving from an outlet of the compressor are directly conveyed to the second heat exchanger and then return to an inlet of the compressor, and the refrigerants are stored in the liquid storage device. The refrigerating device further comprises a branch flow path, a control valve is arranged on the branch flow path, in the hot air bypass heating mode, the control valve can be opened or closed, when the control valve is opened, part of refrigerant leaving from an outlet of the compressor passes through the branch flow path and then is conveyed to the liquid storage device, and when the control valve is closed, part of the refrigerant is conveyed to the liquid storage device through the branch flow path. And when the control valve is closed, a refrigerant stored in the liquid storage device sequentially passes through the throttling element and the second heat exchanger and then returns to an inlet of the compressor, and under the condition that the control valve is closed, the branch flow path is cut off.
