The present invention provides a control method, a vehicle, and a constant-temperature transport system capable of suppressing a reduction in heating performance. The constant-temperature transport system comprises: a compressor (21) that compresses a refrigerant; an exterior heat exchanger (24) connected to the downstream side of the compressor (21); an interior heat exchanger (29) connected to the downstream side of the exterior heat exchanger (24); a hot gas bypass pathway (33) that is connected to the discharge side of the compressor (21) and that supplies the refrigerant to the interior heat exchanger (29) by bypassing the external heat exchanger (24); an expansion valve (34) provided to the hot gas bypass pathway (33); a temperature detection unit (35) that detects the temperature of air affected by the interior heat exchanger (29); a pressure detection unit (36) that detects the pressure of the refrigerant on the outlet side of the interior heat exchanger (29); and a control unit that controls the expansion valve (34) such that, on the outlet side of the interior heat exchanger (29), the saturation temperature, which is dependent on the pressure, is lower than the temperature by a prescribed temperature.
